The best one I have seen on working on diesel engines on TH-cam is Matt from diesel Creek. Try contacting him and he may have some suggestions. He just did one with a pony motor a couple of weeks ago
Salvage workshop is another good channel. Matt from Diesel Creek is great!
Seconded re: Matt from Diesel Creek!
Yep dropped down to say the same thing. Matt definitely has some knowledge he might be able to drop.
Yip I Follow Matt to. He really knows his stuff.
I never thought that I would see a will it run on your channel it makes for good content plus I think it would be neat to operate a Caterpillar I think you guys just have to have fun that's all there is to it you're not allowed to not have fun
I had good luck cleaning and preheating the spark plugs with a propane torch. Also try putting a little marvel mystery oil in the cylinders and crank it over and lub up the rings.
That is a great tip, that our friend Dave did try. But no luck!

Agree, Marvel Mystery Oil is a good choice to put in cylinders of engines that have set for years. Been using it for over 50 years to pickle my engines for long term storage. And it's the first thing I put on top of the pistons to lube the cylinder walls when I pull them down and prep them for use. Been known to pressurize my oil line through the oil pressure port to oil all the bearings on my motors too! That way the bearings are dry when I hit the starter so I can build up oil prressure.
I still think you might not have the good compression.
What a great tease for “next time” in the last 5 seconds!
😉
I enjoy your videos. You two work so well together. And, you two are not afraid to dig into anything.
Spark externally is no guarantee of spark internally. Start out with a new plug. Dump a little seafoam into the plug hole. Let it sit overnight to free up any sticky rings. Put a compression gauge on the pony engine when you try to start it. Put a voltage tester on the plug wire also. Check to see if they are within specs. Depending on the results go from there
Yes, hubby said same thing.
@@ORSkiewhat, put a squirt in the hole to free up sticky ring.
As retired heavy equipment mechanic somethings are meant to walk away from and this is one. Unless it is free and you have money and time to put into it. It would be a fun project if you are interested in doing the work, because they are good dozers and well built. Hope for the best and enjoy the project if you go down that path. Can't wait to see what you decide. Love your podcast. Keep up the good work
It is free (to use). How much time and money they want to put into it is the real issue.
im sorry guys im laughing when you guys tried to pull the dozer..but nice try 🤣🤣
It takes a dozer to pull start at dozer
It was a fun experiment. 😆
I knew where this was going 😂
@@AmbitionStrikesthat hand cracking on that caterpillar dozer is kind of tuff but that engine won’t start up I love you guys 😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎
The day my dad sold his d7 they pull started it with two tractors, they used chains and it wasn’t settled into the ground.
courtney please stand back farther from those tow straps they can whip back plus if the chain breaks it can whip dangerously close to you. I'd hate to see you injured or worse. you guys are awesome don't want to see you hurt. don't give up we are all praying for your safety and success.
Marty T is another one that rescues abandon heavy equipment
Someone made a comment contact Matt from diesel Creek that's actually a fairly good suggestion he works on a lot of pretty old equipment and seems to always get it going
Well, at least you’ve found Squatch 253, absolutely love that guy’s channel!
Clean the carburetor, make sure the float is working. 10 year old gas has ethanol in it and it deteriorates to a varnish that gums things up and is far less flammable. Even with direct feed of fresh gS, the old gas may have plugged up jets in carb. Some engine oil or Kroll or Marvel Mystery oil in the pony motor cylinder could restore sufficient compression for it to fire. Good luck.
Using hind sight, it is very lucky that D7 didn't start.
You ended up with the right dozer for you, and I love an older D8 Cat. They built the world.
I love how you still share your experience even Though it’s a failure. Thank you Riley & Courtney
Good Luck, keep at it. No first hand knowledge on dozers but Intake and exhaust blockage are the first things to check for vehicles sitting in fields- mice squirrels snakes chipmonks etc make nests in the craziest places.
Good Luck, cant wait to see it run and Reckless pushing on the road!
My wife is 76 and I am 73. She is a city girl and for some reason she cannot get enough of you guys. We too live in the woods but not off grid, but whenever I am outside working on stuff, she is no where to be found....lol keep videoing!
You could use an impact gun to start the pony motor, instead of the drill, it has more torque and turns slower.
Check if the pony motor exhaust is plugged and also check the intake, It might be partially blocked. You need three things for an engine to run Fuel, Spark (timed correctly), and Air. You have the fuel and the spark so it stands to reason that it might be air your problem.
What about compression ?🤔
The impact will most likely damage the 90 degree gear box. The gears inside as well as the keys for the gears will not like the impacts. Usually the gears shed a few teeth.
@@tireballastserviceofflorid7771 I appreciate your thoughts on my suggestion. I'm just curious, have you tried this method and experienced this happen? I have not.
I just watched a video from the Deboss Garage TH-cam channel and he tried starting an old hand-crank start engine with an impact gun and it did not work. This is the link to his video th-cam.com/video/b0N-J9QRwSk/w-d-xo.html
Courtney and Riley maybe get in touch with Richard from Deboss Garage Heavy Duty TH-cam Channel for suggestions to start the bulldozer. He has many years of heavy equipment mechanic experience.
@@kevins.7990 Yes I have tried to operate small gear boxes with an impact. I was a Journeyman mill Wright for about 20 years before opening my own welding and fab shop for 11 years. Now I do tire ballast/service and have a tiny farm. Seen countless people over the years try everything from spinning a Briggs and Stratton to a Wisconsin V4 with an impact. Usually something will brake within a few seconds. As a side not. Basically speaking no gear box is impact rated. The very nature of the impact is bouncing the load will literally bounce the gears and chip of brake them off entirely.
This is a job for Salvage Workshop. Or, Heavy D Sparks is also good at rescuing these old machines...and he's not too far away in Salt Lake City. I wouldn't be surprised if you could get him to bring his whole crew up to your area to collab on a rescue.
Reaching out to other TH-cam channels is a great idea.
Absolutely call up Dave Sparks. He's helped so many people with stuck equipment or even stuck tourists 😁
Dave sparks and his crew get them running just enough to load them and you never see them again, they want to use it not get rid of it. Get ahold of salvage workshop if you actually want it useable like you planned. Hes very handy with everything
@@jblazer147 Either person would be helpful, they are not looking to restore a dozer, just get it running and moving.
@@bullzeyez3236 didn't say restore it but you need to properly fix it to dependably use it. Dave is not near as good as everyone thinks he is. Building trucks is a whole different realm from old equipment. He does the rescue stuff but I've only seen him start one thing the rest he drug out and the one thing I did see him start he just loaded with either till it finally did. I like the dude but he's got alot to learn
Hi guys,
I love your channel.
Perhaps try this:
1. get the pony motor’s carb rebuilt
2. Buy new plugs
3. Make a drill adapter that does not use the hand crank
4. Rent a stronger drill
5. Pour a small amount of an oil designed to boost compression into the spark plug holes.
6. Install the rebuilt carb
7. run a hanging fuel tank and new fuel hose to the carb
7. Turn the pony motor over a short while with the drill
8. Reinstall the plug on the wire and check for spark by running the drill
9. If there is spark, reinstall the plugs
9. Pour a small amount of fuel into the breather tube of the carb to fill the float bowl
9. Confirm there is fuel squirting into the throat of the pony motor
20. try it with the drill
20. only use a small spray of ether so as no to flood it
Good luck
Don't give up guys! That's a perfect doser for you just needs some love and work!!! You guys are doing great.
Would love to see this resurrected
You guys are on the right "track", haha.. Lotsa muscle in that baby! Hey, I agree with the posters that said to check the carburetor on the pony engine.. Carb no right.. nothing going to happen.. as others have advised, make sure your pony engine isn't linked to the diesel engine (probably not, though).
My dad taught me how to drive a D5 at 5+ yrs of age. Riley, you are correct, it's next to impossible to see over the front.. a VERY shallow view angle.. takes a bit of practice to overcome. Just my .02.. good luck!
"Ran When Parked"............ LOL! I know this is gonna be a Reckless Riley EXTRAVAGANZA! And I was right! The only thing you didn't try was explosives! Really glad Riley didn't wreck himself with that crank mess.
I am proud that Courtney did the critical task of socializing with the nearby dogs!! Tops getting the dozer started in my opinion.
Mellow Yellow is the official greeter at our neighbors house. ☺️
Just like the dozer I started on 50 years ago👍 Fun Fun!!
Definitely check compression. If it didn't blow the cork out it's not a good sign. A little bit of oil on top of the piston can bump up the compression for a first time start (helps the rings seal a bit better when they get sticky). Has worked for me in the past.
Jack up the blade while holding the lever and chain it , a good size loader will work as long as you pull the lever. You're going to need another dozer or a large loader. Remember the tracks have been sitting and rusting. Even though the plugs are firing I'd change them out. I had the same problem. Good video.
Tired from vicariously pulling on the starting crank. Get it going so I can ride along. Always wanted to drive one. Had an IH 484 diesel tractor for a few years. Loved what it could do, yahoo!
you said you were going to jump start the bulldozer I immediately flash back to 1972 when we had a 1966 VW bug. I lived on a dead end alley and our homer was a little over half back of the dead end. If the VW didn't start you would run it down the alley jump in pop the clutch and pray it starts. Well sometimes it didn't and I would by myself have to grab the bumper and drag it back up the hill and. try it again. I thought how in the world are you going to jump start a bulldozer that huge. All the things you had to move just to attempt this. Cannot wait to see your next video....looks like you got it started.
This reminds me of the old Boy Scout skit where you end up asking how many jerks does it take to start a lawn mower... 🤣
Hand cranking pony motors is a hard thing, even when they have been running recently. Hand cranking one that's been sitting for years or decades can be impossible. I had one from a big generator D318 cat engine that wouldn't give me any sign of trying and I felt like you guys probably do, even though everything was right with the fuel and spark and timing. Luckily for me, I have 2 other D318s in a grader and dozer, so I robbed the electric starter off my grader and put it on the generator. The pony fired right up with the faster cranking of the electric starter. If you guys really want that dozer, find an electric starter that will work on it and you'll be less frustrated every time you use it.
Great video Riley and Courtney
I was just thinking about starting the pony engine. Did you make sure it was disconnected from the main motor? A 2 cycle or a 4 stroke should be easier to spin.
1) PONY - STARTER: I suspect fuel system for pony (starter) out of service due to water & rust. Are you sure it is disengaged from main diesel engine? Expect back fire(s) when fuels are being pushed into carburetor.
2) DIESEL SYSTEM: I suspect main fuel system water & rust bound. 15 years of any residual diesel separating into water & crud. Remember 15 years of freeze thaw.
3) DOZER CONTROLS: make sure dozer in neutral just in case you actually get "lift off."
4) Recalculate outsourcing costs for road obstacles.
5 ) DOG CHATTER:
- Orange pup to white pup) "Look Snowy, two legged hoomuns on our yard toy."
- Boone to Riley: "Time's up! You playing with stoopid clicky finger toy on lap. My turn for flying squeeky toy!"
🤗🙏🤲😎
Hi Donald! I'm sure the carburetor on the pony needs a rebuild but we can't even get a cough out of it on starting fluid! Yes the pony is disengaged, in fact the clutch is stuck and we can't get it to engage, another obstacle. Fingers crossed the diesel will run! The dog commentary is too funny! Thanks for watching!
Remove the spark plugs, spray starting fluid in the cylinders, install the plugs & wires, and crank. You should now have some sort of ignition.
@@AmbitionStrikes Check the fuel pump and extract the gazoline from the tank. Replace with fresh gazoline.
You have to talk to them .I was 17 when I got the chance to operate a D6 probably same year as yours mine had crank through hood too.Cat Skinner walked away from it spouting 4letter derogatory remarks all the way to his truck and left .They said that if I can start it she was mine for the rest of the job.Drove it up to the foreman and climbed down told him the repairs needed and I didn't have a torch or welding machine and I'd make do but needed a shop truck first thing in morning.The rest of the day I drug trucks in and out of massive muddy trail and back dragged to a semi flat surface. I got 7bucks an hour and felt like getting paid to go swimming .Talk nice to her and she only weights 3 or 4 times what humpty does so don't get it stuck near that pond of yours!!!!!!!!And put the can on the stack every night too, keeps out rain and critters.
How exciting a dozer how cool is that hope you get it started that would be a game changer GOD BLESS.
Well.... That was fun!
As I remember the need for bigger equipment was because of a boulder too big for your current equipment. Perhaps you are approaching this from the wrong angle. Make the boulder smaller rather than the equipment bigger. Or as an army engineer I knew said " It's nothing a key of C4 won't fix!"
Title for the video. "Reckless Riley explores explosives!"
We still have about 1 mile of road to build (hopefully this summer) so we have decided that it is time to find some larger equipment. The quotes we go to rent a dozer (or larger excavator) are about $12,000/month so we are trying to explore other options!
@@AmbitionStrikes Ask local viewers who own a larger bulldozer ie a D8 to come for a couple of weeks to be part of your videos in exchange for cash to cover expenses,(fuel) etc. and their company gets national advertising , even go so far as to go out with them to do a completley seperate video just on their work sites. Use your fame to your advantage. JR
Matt on Diesel Creek channel is really good at getting old engines started. Give him a shout.
13 year CAT parts guy, they make a changeover from the pony motor to electric start. Don't know if you want to invest that kind of money in it but it is available. Also, the serial number plate should be in the cab close to the bottom of the dash, if it's not there it will stamped into the frame where the winch/ ripper is mounted. Hope this helps.
That is an early 1960s D7 no cable controls for your blade. I was building those pony motors for that D 7 , D 8 , and D 9 s back in 1972 ( my first job after high school and 18 years old I started working for Caterpillar Tractor , before they changed to Cat Inc. ) but those had an electric starter instead of the crank ( if the battery was dead back then you still had the crank as your back up ) . You need too check a couple of things …
1 . The pony motor spindle or return spring is broken and drive gear on the spindle is still engaged to the flywheel
2. The diesel engine is locked up or hydro locked with water in the cylinders ( happens if exhaust was not covered or air intake was compromised allowing water too enter cylinders )
3. The clutch pressure plate is stuck to the flywheel
4. Check oil and fuel on the diesel prior to start
5. Carburetor needs to be cleaned and rebuild with all that rust in the fuel tank
6. Pour a ounce of ATF into each cylinder of the pony motor to lube the rings then crank the pony motor to insure all the rings of each piston get lubricated they may have stuck in the piston .
7. Change the oil in the pony motor and look for bearing material and metal shavings
8. Check your valve lash on both the intake and exhaust valves of each cylinder to insure
you close and open the valves according to your timing .
9. Check the spark plugs are clean of carbon and spark plug gap is correct.
10. Gremlins are everywhere , the transmission is in neutral , the little things we sometimes overlook
After 45 years , I retired from Cat as an engineering technologist ( engineer without the paperwork )
and have worked on engines , undercarriage , transmissions , crawlers of all types , and worked in validation of the C 175 engines torque converter transmission for the 797 off highway truck Marine application Power production generator application . Good Luck and hope that tractor gets running to fix your road .
I didn’t read all of the other comments but I’d say put a little engine oil in the cylinders to help the piston rings seal better and create more compression. After sitting a long time stuff dries out and oil film goes away, might help it turn over slightly quicker/easier too. I’ve spent some time on those old Dozers and I hope you get it running, it’s big enough to do a lot of work if it’s mechanically sound enough, also it will be a good experience and good videos. You pretty much need another crawler to pull start that one.
Transmission fluid works better. Leave the spark plugs out while lubing the cylinder and rings, Spray brake cleaner into the cylinders and turn the pony crank thru a few times before replacing the spark plugs. Also spray spark plug spark gap so the plugs will not be oil soaked. Use starting fluid to assist in starting.
You two are just awesome. That fact that you just keep trying with smiles on your faces and great attitudes -- I love this channel. It's so much fun watching you. Even without the teaser at the end showing that you do get the dozer running...it would still have been video-watching well spent. Wishing you good luck on all your future adventures!
If things are supposed to work they will, and sometimes things do not work the way you want and that is for your safety and best interest Kind of a divine intervention. Like the videos Stay Safe
Don't give up, the best things in life are never easy and that's what makes you love them more. Get a bunch of new plugs and change them out as they can get fouled with a number of reasons and check the timing of the MAG to tdc so it is sparking when it is suppose to.
❤️❤️ I gotta be honest, this was a hard one to watch. I thought for sure Riley was going to end up in urgent care.
With that spinning handle, I CONCUR !
Check out some other great TH-camrs that do a lot with old equipment: Squatch253, Diesel Creek, and Salvage Workshop. All do a lot with diesels and they have all done pony rebuilds. Squatch 253 is a guy that does methodical teardown to every component and rebuilds to factory specifications. Salvage Workshop goes to the level of rescuing and getting things running. Diesel Creek restores to operational use and then works the equipment hard.
Collab on location with Diesel Creek and Salvage Workshop?
Definitely Salvage Workshop. He's done rebuilds on Pony motors and Matt @ Diesel Creek of course Did you do a compression test with a gauge?
Love the 58 international flatbed in the background
Good luck getting the cat running
RR Singing......I'm spinning around Move outta my way I know you're feeling me 'Cause you like it like this I'm breaking it down.
No advice needed for the dozey duo as you've managed to crank it up. Well done both!
Check Salvage workshop he has just brought a D6 back to life also Diesel Creek has a magic touch with old kit. Also get there advise on price. Seems a bit to pricy. Towing a dozer with the blade down. Riley is earning his reckless status. Keep up the good work.
OMG! I fell out of my chair laughing when the pull cord broke! It happens to me ALL THE TIME! Everytime I need the generator or lawnmower..boom! cord comes off in my hand. Always after I been my shoulder out and tired! JUST GREAT!
It's always at the worst times!
You guys have an admirable amount of patience!
Those old machine can sit for a very long time and still fire up and run. Just takes the right trick to get it to go.
I had a old 7 like that. 14’ blade if I remember correctly. We had to completely rebuild the pony motor. Even after the rebuild the whole machine was kind of a pain to start. Pony motor was loud, the main engine was awesome, but just too many steps. I’m guessing that you can find a working pony on a scrap cat somewhere in Oregon, Washington, Idaho. Happy dozing 😁
I’m so happy I’m not the only one with that luck!! You already have 965 problems then the generators like “hold my beer”
I just discovered yawls channel today. I love watching all the equipment get restored and running and excellent try by attempting to pull the bulldozer with the truck. Physically, I knew that it wouldn’t work because these old dozers they require so much to get them running.. that pony motor Hass to be able to run it almost full power to get that engine rotating it’s basically a lawnmower engine strapped to the top of the diesel engine but good thought though but I really think I’m gonna enjoy your videos. Also, I’m a totally blind, TH-cam watcher, so I am extra fascinated by this stuff.
We had an early D7 and D8 at our high school ROP class with hand crank pony motors. Even older models are possible. We had cable operated blades and earth movers attached. No hydraulics whatsoever. As far as advice for starting the pony motors try cranking on them like you would when kick starting a motorcycle. You have to slowly get one cylinder almost set to TDC then give it a good strategic crank. It should be enough to get it to go if everything has been trouble shot like you have been doing. IIRC your body positioning on the track when giving it that last good crank should be about 45 degrees or so not 90 degrees perpendicular. Sounds weird but the strategic crank is what worked for me. Additionally I got proficient enough to engage the pinion on the pony motor and release the compression on the diesel side and pull the diesel throttle lever get it started and kick the pinion back in place all by myself. It was tricky but definitely doable with one person. You can DM me directly if you want a more in depth walk through.
Burl
Takes a dozer to drag a dozer that has not moved in “forever”. Focus on the basics like you were doing, run a compression test, good to spin pony engine without plug to exercise rings, spin mag with a spark plug attached, should be a “fat” spark, if both ok, should “Pop” with starting fluid. If getting signs of combustion, clean carb fresh gas and give her a try and another…BTW, the big Diesel engine will be much easier to start!
Yea i was thinking they might need a crane to move it. :)
Lucky they didn't break the army truck. Do they realize how much the cat weighs? I was waiting for the pony motor crank to hit him in the nuts.....
Make sure the carb and intake are clear, in no nests or any blockage. If I were working on this dozer, I would pur a little time in and clean the entire fuel system. If it has spark, compression and fuel all happening at the right time, it should run. Good luck.
You guys can do it 😉. Think how much fun Crash it Courtney will have getting even with the trees 😳
😉
Crash it Courtney! LOL!
You guys have far more patience than I have..... somewhere on the second day I would have pulled out the C-4......
Damn old dozers are my specialty. Hard to do without hands on though and my entire service truck though. I am local though. I’m sure Riley can get it running. Persistence is key.
Morning Folks - consider using a Kevlar rope to replace the generator pull cord. Should last longer
Look, if the other machine moves some, then its enough to tow start but it does need to be done right theoretically... fuel pressure up and oil circulating.. that said, its not the end of the world to do it once as its just junk to most if its never going to run. Usually those pony motors were easy to start as that slow pop over was a high impulse and would make its most juice to the plug to start. I was born the same year as the dozer your trying to start, my dad was construction/logger/miner so I did wear out a half dozen of those. You may wind up pulling the head of of the pony engine, cleaning it up and clearing the rust off of the valves. If it has a copper head gasket, put it in a pan of water and boil it so it swells up an will retighten. No reason for it not to be a easy start engine.... most of those had the provision to add a starter onto the pony so a battery starter could be added to the mix
Are you getting any fuel in to the cylinders? After all that cranking you should have a good smell of fuel when you remove the spark plug. If no smell the the carb needs a good clean. A little drizzle of fuel into the cylinders might givge you the extra kick that you need. Thanks for posting
You've probably already found him on youtube if you've been looking up dozer rescue, but maybe send a message to Rich from DeBoss Garage / DGHD. One of my favourite heavy equipment rescue channels and he seems to be a really nice and knowledgeable guy. Good luck team, sending big hugs from NZ
Apply WD-40 on all joints you can find on it and let it rest and cure for a day. That way atleast there will be lesser resistance to parts that are trying to move. Secondly, disconnect the gearbox from the engine. This will ensure that it won't move forward when started. More importantly it will enable free start of the output rod. These old engines need to be started in neutral because of old design of cylinder heads. Cold start is always an issue with these old yet beautiful machines. Great content guys. Looking forward to more videos. Please please please post more videos. You have a great property and truly great content. Peace ✌🏽 😄.
Don'y forget to put air in the tracks.
Ahhh yes air in tracks that makes sense
Hi Riley & Courtney
I have no idea how to start that thing.
But laughed my head off watching Reckless Riley try.
Love that nickname.
As persistent as he is . I'm sure if he decides to keep trying he will get it.
Lots of luck.
Stay strong and safe
See ya next time
I grew up using a D 8 as my jungle gym . Brought back many memories 🧡. Thx
That thing weights probably 3 times the truck + is nested in the soil.. Well, first of all, I suggest you check fuel lines, clean the tanks and only then try to start it up, especially the main engine. Other than that, check the line valves, sediment collector and filters as there might be some water, sipped through cracks in the exhaust.. 20 years are a long time and a machine becomes almost "fused" by sitting in the rain. Also check the carburetor of the pony as nasty stuff might be inside. Other than that I leave some ingenious approach to you... If you turn it on the first pull, where's the fun? =)
Oh those moments, when you need a tool and then it breaks, so you need another tool and work to fix the tool you need to do the work... Pull string snap - priceless... =/ I could feel your happiness..
Wow, that's the vintage of dozer that I learned on. Although we started the pony motor with a rope wrapped around a pulley.
You will build lots of strength with steering clutches and steering brakes.
Take the carb off and clean it. Gasoline leaves a nasty residue when it dries up inside of a carb. Ream out every jet and the idle circuit.
Man o man she's really cute...😁😘😘😘😘👍 Those eyes are gorgeous!👍
Mimick the catch pawl from the handle and weld a pulley to it. Then add a bumper/ door knob-ish to he top to hold pressure on it. Then have Courtney wrap a rope around the pulley and go. It’s an old school motor old school pull start. It has all the things it needs and at the right times just not the right speed to create real compression. The drill was a good idea just not enough umph. Be careful and thanks for sharing!
Have you guy's ever watched any of Andrew Camarata's videos? I know you don't have time probably but he has some really great stuff and millions of viewers, he is a heavy equipment oporator and works on all his old stuff like this dozer, he built a shipping container castle that is insane and is just a top notch guy and video editor, dog lover etc. Also Diesel Creek with Matt is also has a really awesome channel. You three are my main go to channels.
And rough as guts, a chainsaw to install a radio?.....
You guys are great fun to watch! Reminder there are two top dead centers for a four-cycle engine, Intake, compression, engine firing and exhaust. For the correct TDC for firing make sure the rocker arms are loose and not pushing on the valves, use a screwdriver in the spark plug hole to see when piston is at top dead center. I almost thought the electric drill was cranking backward at one point.
Thought the same thing about the backward cranking. Think it was an optical illusion . . . .
Friend of mine got a hold of an old D8 that had set for years. Cleaned the carb and the fuel tank, mag had spark. Same kind of hand crank. That thing would pop and spit enough to keep you cranking but wouldn't start. Had the magneto on and off, replaced the condenser, still wouldn't go. Got tired, took the coil out of the magneto, a little drilling and wiring and we were able to mount an external automotive type coil to work with the points and that rotor in the magneto, hooked up a 12 volt battery and it started second crank. Sometimes the innards of those Magneto's will go bad, they Will still spark but not strong enough to run the engine. At that time it was about 300 bucks to get a rebuilt magneto, we had these parts laying around and just wanted to get it going to see if the rest of the machine was any good. it was.. An old farmer around here had three old caterpillar machines with pony motors. Only one would run. He had to start it to pull start the others. Before it was all over the gears that pony motor tore up and he ended up pull starting things with an old TD9 international.
That is a great cat I had one like it and I loved it
Use a impact gun cordless, for starting (more torque). Remove the carburetor, spray starting fluid directly into the intake.
That kind of bulldozer will solve your trouble with the road. It's quite heavy job to make the road properly so you need heavy tools to do it. Certainly try to get the dozer in use, even if starting it up might take some effort. If you plan to tow that bulldozer, you probably need another bulldozer to do it. If you had such dozer functioning for winter use also, there is probably enough power for any snow pile, but also make sure it doesn't break on the road, it might be quite a trouble blocking the road.
If it breaks down on the road then we are going to have to get an even BIGGER dozer! Maybe that is secretly Riley's plan... 😉
My father taught me to remove the plugs; crank, and see if a finger in the spark plug hole gets wet with fuel. Then connect the plug wire to a plug and hold the loose plug body to a ground and crank to see a spark. I like the other comments about fuel turning to varnish. Now for your scolding. WHAT WERE YOU THINKING letting that crank fly around!!!!!!!! That made me scream. I Have plate/screws holding my wrist on due to a back-fire accident. And while I'm scolding add some safety straps to that garage door! The stress on the screws may someday work-harden them. Then they can all get brittle and snap at once. You two are my favorites, you got married! Bless you.

Use your D8 to pull start the D7.
Once started engage the start clutch to start the starting engine.
Time to reach out to Diesel Creek your , fellow TH-camr.
Good luck!
patience Riley should be the new name, took lots of patience.
Great D 7 . I was raised in a house with 3 older sister's. The middle ones husband is older than that Cat and a Diesel engine mechanical Genious. I'm glad you have a great woman around. Like my sister she is sharp and knows how to say Old man take a break drink some Ice tea and go back at it tomorrow. She also if given the information and what she needs to get it done will do it herself. When she tells us get out we go . It's for our own good . Lead fallow or get out of the way or no supper for you . I have seen good Woman get old things running when the old man just got frustrated. Keep doing wonderful things
i have a D6 9U.. pony motor was trash... (not sure bout the D7) but there is a V belt pulley on the back of the big motor, we took a snowmobile motor & mounted it to the frame & a V belt around the pulley on the big motor!! ( the neighbors are now deaf) but it started it perfectly!!! then we started pull starting it!! fill the bed of the army truck with a load of dirt, jack the blade up out of the dirt & just use the BIG chain ( no strap) & leave the compression release on the big motor open, get it out of where its sunk first THEN try to dump the compression release & pull start it!!! hope this helps & be safe!!!
Now we're talking fun times. I love the good old machinery! I put money on it (before I saw the teaser for the next video) that you will get that ole girl running. You have the know-how, the ability to build anything and you have the mind and education of an engineer. What a challenge but omg this is what makes life worth it...and the stories you'll tell for years to come. They just don't make engines like that anymore. Maybe remove the carburetor and soak the parts in some gasolene overnight. I'd not pay $10k for it though. The old dude has some really great vehicles to play with. His dogs are adorable too. Ironic advertisement for life insurance lol.
Thanks so much for the support and kind words. We agree that if we can get it running the carburetor could definitely use a rebuild. He's a great neighbor to have with some awesome old treasure!
I dont think it was the same dozer in the teaser
@@centurion726 interesting thought I was looking at closely to see if it was
@@x35mmman The old had round roll bars the other had square
"A" For effort. i hooe you can get it going. i was cheering for you while watching.
I'm not sure if your tried the plugs out of the head to see if they arc. Best bet is to just get new plugs. Corrosion is generally conductive so they tend to shourt out inside. And when I saw gas come out that means the plugs are wet. Wet plugs won't acr. You can try fine sand blasting, the only good way is to replace them. Also your timing procedure looked OK but I think there is a chance your 180 out. Highly unlikely since it ran when parked. I have seen those mags on old John deere tractors and they can be finicky. But your making hot spark. Also soaking down the bore with a quality penitrating oil for a few days by keeping it wet. That will help the rings losen up and create more compression. Also check the start mechanism to see if it can be lubed anywhere to reduce drag and increase crank speed. Also hit the valve guides with penitrating oil to help losen the vanishing. Even a tiny tiny amount of drag will effectively change the valve timing and will make starting very tough. I recommend Kroil or PB blaster only.
The thing about ether. If you know 100% you have spark. You will get a pop or kick back no matter the ignition timing. So the fact you get no pop or kick tells me the high tension from the mag is not creating an arc in the cylinder.
Any time you fully flood an engine you always need to pull the plugs and spin it over to dry it out. Otherwise the mist generated inside the cylinder can and will short out the plug. Especially old weak ones.
Before you start the main engin all the oil need to be checked for water. One it runs keep it about an hour and the change all the filter and the oil if you can. The hydraulics are the single most critical system on the machine. Also the most expensive to maintain. Not woth a short cut. Also should change the engine oil filters before it starts or cranks. Again an expensive system.
Also giving a generous dose of grease to all bushings before being activated. If a pin rust tight inside a bushing it's possible to spin a bushing when it first moves.
If I were a few thousand miles closer I would swing by and fire it up for ya.
Keep after it and be patient. Would be a really cool project.
I would love to have that aluminum boat with the teeth on it. Make it my gator boat!
I would also add. The main engine cylenders should also have the cylenders soaked a little before its cranked over. Give it a big doasing of penitrating oil and then let it dry out a few days before you crank it. Maybe even a little blast of air. It can be tough to acess the cylenders on a diesl, but would be worth the effort. Excess oil can cause a diesel to Rev pretty hard when it cranks over.
By the way. That thing running is worth a fair amount of money. Good luck
The bigger the toy the more FUN it is... Much love and prayers, be blessed in Jesus name... BBE//
Call diesel Dave!
Very cranky smiles 😊☺️☺️
take the carb off and clean it . also check the fuel line. change the gas filter. check the exaust for mouse houses and the intake air. put oil in the plug holes to help seal rings. I would make another adapter for the crank starter and get a straight shot without the crank handle trying to kill you. Use a good strong impact gun. It's a good idea to take pictures of everything you take apart. your memory is not as good as you think it is. lol.
This is the first time I have seen Courtney climb into the driver's seat on the army truck, is this why Riley wants the dozer, because Courtney has stolen all of his toys? Seriously I would expect the pony engine to run on starter fluid if it has a spark and compression, assuming that the inlet valves were opening, if they didn't close, you would have no compression and it would backfire through the carburettor, I suspect that the spark plugs are possible waterlogged or the gaps closed. Great vlog as always, stay safe.
Looks like you found a different dozer. Great content, keep up the good work.
Did you engage compression release on main engine, or set to start? Next, make sure you have compression in pony. The valves were moving but did you check for compression, biggest issue with "sitting" engines is stuck rings. If no or low compression try soaking cylinders in light oil, or trans fluid. Pour oil in cylinders and spin engine, let sit overnight, then add more oil and spin again. Hopefully rings will release and start to make compression. Once you have pony compression, check spark at plug, remove plug, connect to plug wire and ground base, spin engine and check for spark across gap. Your alternate source of fuel (propane, ether, external gasoline) should allow pony to start. Please find better way to spin pony, can't you connect drill or impact to shaft without handle, maybe a square socket? Don't want you to break your arm. Best of luck!!
Hi guys, another great goal! As soon you can cross Africa and you will make lots of friends. They are the kings of all the wreckage you will be in heaven. start on a bike and finish on a beautiful DC3 Or an old factory trawler. this continent will be your paradise where you will find great torch and pipe wrench technicians in the villages.
I think your pull start plan is a good one. You need to lift that thing with another piece of equipment to free it up. It’s pretty much suctioned into the mud for over 15 years.
Don’t give up. Pull and throughly clean the carb. Make sure air intake and exhaust are free and clear. Stay with the bypass fuel source. Go back and watch The Sasquatch 253 you tube channel again, those old magneto ignitions can be tricky and there two parts to correct timing them. He just did a episode on rebuilding them
Squatch 253 is who you mean.
Well good shot guys but it was fun!? Cant wait until next time 😁
This video is one of the reasons why I enjoy your channel.
Lol, have you considered just renting a jack hammer/rock breaker that mounts on your excavator? FWIW Andrew Camarata has many vids showing how these work and how to use them… they’ve been around a long time and work well. 🍻😊
