You may not be able to notice with the current eye issues, but your old camera was a potato. Your style has matured well, production quality is up, sound quality is up and some of us like the same story retold! You are a Caterpillar Bard in the Tavern of Old Iron Lore.
We used to have a saying around the shop whenever we found metal in some component "Can you see any part numbers?" But I've never seen a chunk large enough to have a P/N, or other identifying marks until now. Yikes!
😢if. They pull that RD6 with the compression lever in the open free wheel position then pull the RD6 in compression and start mode she would still be in better shape Having the old starting engine gives you a chance to blow out what ever is in the cylinders. Awesome video and story. Denis from Santa Rosa CA
I'm amazed the block isn't destroyed. Dad had a farmall diesel tractor with a cracked head. We used it that way for many years, he always kept the radiator cap loose on it. One day I filled it with antifreeze and put the cap on tight. Water got forced into the cylinder with the crack and it was that same scenario. Liquid can't compress. The rod broke and the loose end broke large holes through each side of the block exploding anything bolted to the outside. I was stunned. It was still running when I shut it down. It was a good candidate for a rebuild until I did that.
The curled chunk of metal resembles shavings from a metal shaper or metal planner. That was a lot of power to take a cut that deep! Thank you for the video!
Using marvel mystery oil in fuel helps lubricant everything keeps valves rings free And helps injection pump ... and use pony engines if equipped plus power services additives helps
RD6 content! The very first time I caught your channel was D6 stuff. I was so naive.... I thought these were 1960's-70's machines. A quick TH-cam search showed me that these were pre-war machines. Been hooked ever since.
Water is quite amazing! And it will not compress. Back in another life (40 years ago) I worked in a sand and gravel quarry. The sand was mined with a dredge off the bottom of a lake. The dredge's slurry pump was driven by a Cat D353 with an Ingersol Rand air starter. The after cooler started leaking and when the operator went to start the engine, not only did it bend a rod, but it also popped the head off. I have pictures.
The mechanical advantage of the crank pushing the connecting rod at the top of the stroke (and the bottom) is enormous. It takes many degrees of crank rotation to raise the piston the last few millimeters.Obstruct the piston in some way and something has to give ,and it's usually the rod. The situation is worse where there is only slightly more fluid than the volume of the combustion chamber. This is where the mechanical advantage is greatest. If the cylinder was half full of fluid , the crank rotation may have stopped with no damage at all.
Aviation piston engines will do this occasionally. On radial engines it’s why you see them rolling the engine over by hand before a start. They are checking for a hydraulic lock which happens when oil or fuel accumulates in the lower cylinders. It will be interesting when you get to start the disassembly.
Hi Squatch - long time viewer, first time commenting. That's some serious carnage that engine has suffered! But we all know its in the right hands to address it. This past weekend I attended the HECA's (Historical construction equipment association) "Last Blast" 2023 just north of Barrie, Ontario with my 2.5 year old son and dad. It was awesome seeing so many vintage machines running in the quarry pit (especially the steam powered shovel!) and seeing all of the static displays, and hearing the IH and CAT power units! My son is obsessed with all of the machines (and me too of course) and all 3 of us thoroughly enjoyed ourselves. In addition to the various Cats they have an RD6 there with a massive cable operated shovel. I think the info tag said it was used for trenching. It was my first time being up close and personal to such a machine and after seeing all of your videos over the years I have a huge appreciation for them all. The organization has two CAT Sixty's there too - one is a 1926 snow special in great condition and the other is a 1930 model - significant as it's the last original Ontario Sixty. I even found myself doing mock walk arounds and checking for matching serial numbers, undercarriage wear etc. lol. I found myself pointing out to my dad the "knuckle busting" controls on their Auto Patrol #10 grader and how the pony motors worked on the old diesels lol. It's all thanks to you and your dad! Thank you for the great content and for sharing yours (and Seniors!) passion for the vintage equipment with the rest of the world. I always look forward to all of your videos, regardless of what the content is because I know it will be fantastic and I'll learn something new. Hope your recovery continues to go well and I look forward to the next installment!
Awesome video! It’s always interesting to me to go back and look at the cause and results/consequences of mechanical failures in machinery! Thanks for putting this together!!👍🏼
Ouch, I know how it feels. I got the same destruction on my Scania 143, I guess it was the headgasket that failed an filled one cylinder with coolant. I turned the key, it ignited litte and bam, rock solid. Got to take a reciprocating saw and cut the bent connecting rod to get it out of the engine. The same parts from the piston and liner as you got. No fun at all...
This is a great video on the pre tear down etc. to find out what happened, why it did etc. I remember watching the previous video, but I dont remember seeing the reference to the older videos. I will have to watch them and get up to speed on them since this is looking like the next project coming.
I really like you added metric and imperial sizes together. Really gives for us none imperial size knowers a good idea what the dimensions are like. That thing must have smoked like opening of hells gates. Hydro lock has ruined lot of engines, dose not take much for moisture to build up in the combustion camber.
Usually ether will bend the diesel connecting rods especially if you use too much and ether lock the engine rarely happens if you hydrolock the engine because it has to get past the valves into the engine
Great idea giving both measurements.👍 The only trouble is, dress makers use centimeters, mechanics use millimeters.😜 I'll forgive you as you're a newbie.😉
Thanks for the video Toby! These are great videos to put out with your eye healing. Hopefully once Preparation H and x231 are done you can start looking into the RD6. Would be a great series. I’m not a big CAT guy but always interested seeing how everything works. Thanks for the video and can’t wait for the next one! Hope things are still going good with your healing process
I'm wondering at this time all that's holding back the tear-down of the RD-6 if preparation H is virtually the only things left to be done with x-231 is painting much of the parts. And that can't be done until it's warm enough, which is next Spring! I think his eye problem has delayed and reshuffled things somewhat. I started watch his channel when he had just started the tear-down of X-231.
So I guess it’s possible that if the compression release had been opened and the tractor moved a few feet before trying to start it that the liquid might have had a chance to be blown out without causing any damage? It’s kind of sad to think about it.
Been watching you for about 6 years now. Glad ya got your videos sorted out into playlists. Really helps the end user find the preferred content. I got a scar on my eyeball as well. Eye issues are a pain in the rear
I really appreciate your explanation. The damage that results from liquid inside a cylinder is amazing. The forces inside a piston engine are tremendous. I once threw a rod out of a MM Z by stopping the feed on a hammermill it was driving. The tractor was at full throttle and I was too slow getting to the throttle. It was pretty scary.
Those play lists are good for binge watching from oldest to newest. At least in my TH-cam play settings, if I go into one of his play lists and select a vid and watch it, it cues up the NEXT upload automatically. Works great like that.💪🏻✅💪🏻
Excellent video that is what I was thinking would have bent the connecting rod. My dad had that happen to a John Deere G tractor over 40 years ago now it leaked coolant into the cylinder and he realize that and he went to pull it started and it bent number 1 flywheel side connecting rod and busted the block to pieces it became a parts tractor after that
I have to comment here, while not RD-6 related directly. It is adjacent kinda. A while back you were talking about the difference between dozers and tractors. That dozers have front ends nearly even with or slightly behind the front idler wheel. While tractors have the radiator and more proud of the front idler. Since then, I found myself looking harder at such and yep. Spot on true even in the larger units. It's one of those oddities that was seen but not noticed until it was pointed out. And for how to get such a rod bent, it's a leverage thing from pull starting. That as the momentum builds in the machine being pulled, it multiplies through the drive train to the engine. Which all it needed in a cylinder was to have a small pool of unburned fuel or water that as the piston went up for the compression stroke ran into the liquid held in by the closed valves. Then it just became a weakest point, the rod at about the last third of its length. After that full compression couldn't be achieved thus a misfire for a diesel. As long as the liner isn't cracked or the piston itself damaged, a NOS rod can be sourced. A new one machined or if really desperate, the old one straightened. The latter would need to then be fully heated then cooled slowly to get the stresses out that come from work hardening, spot heating. Downside of which would be that rod would be perpetually a risk to break at the repair point. While it may never let go with the use you'd give it. It could just as easily let go at first crank post rebuild.
Good video again Squatch. And I like you every now and then also make the cross reference from imperial to metrics measurements. You’re becoming an global acting TH-camr !
So what are each of these components metalurgy? Piston= Aluminum alloy? Connecting rod= forged steel? What is the liner made of? Something good if it was able to shave material off the connecting rod!
I assume you are thinking the block can be used. Maybe just some easing of the sharp edge where the cast iron piece broke off and should not cause a problem.
Thanks for the RD6 review I seen the earlier and the later but never the actual home coming video maybe one day I will get to it. Keep that eye protected I sincerely hope it's coming along fine.😊
Squatch, thanks for the video. I hope you are well on your way to being on the mend. Understand you may not soon or ever get into that RD6, but if you do, I'd definitely appreciate the videos. I'll go back and watch the RD6 Playlist series, thanks.
Having been exposed to quite a few diesel engines over the years early Cummins had a spring loaded compression release and it was normal to pull it open start the engine spinning and release the compression release to start as this would help expel any build up be it fuel or coolant of course if there was any you needed to pull the affected headband sort the issue mainly it got the motor spinning and circulations oil before ignition
Very sad that on the day the damage happened, no one thought to pull the engine over with decompression activated first.....I hope that soon, you will consider rebuilding the six!!!!.......Very interesting machine!!!!
Iv rebuilt cat 3512 engines with bent rods from head spacer failures those 35 series rods make rd6 rods look like tooth picks, amazing the forces in an engine and the methods they find to destroy them selves
Yikes. That’s a shame about the rod and liner. Hopefully the crank isn’t hurt. Moisture intrusion causes a lot of good engines to be scrapped. It’ll be interesting to see you tear down that engine and see …head, crank, block condition. I rebuilt an early model D 4 engine once that was vandalized. It was 3/4 torn apart when I was hired to fix it. It took me three weeks 3500 dollars and a hand full of trips back to the owners shop to locate all the parts and hardware to put it back together. What a nightmare that was. Nothing was organized when it was first taken apart. And some hardware was never found and had to be bought from caterpillar. Is that one piece remnants of a injector tip? Its kind of hard to see it clearly with the youtube picture paused. Great content! Keep them coming! Lol have a wonderful day!
Ok, I am trying to catch up some on older videos. I do not know those engines that well but from what you said, wouldn't it have been better to engage the compression release and to pull it for a short distance then stop and disengage the compression release and then pull with full compression?
@@squatch253 The crying shame is I am allergic to the chemotherapy drugs due to how the drugs are produced. Corn is used and that is the allergen. The allergic reaction is bad enough the extension of life would cause additional suffering. I am happy to hear you are getting better. Thanks for the kind words
Given the mass and the comprehension ratio of that engine , would it be fair to suspect some kind of crank shaft damage too? From the thrust of the rod bending? And if the liner is broken, do you think that it would have belonged the liner bore? Or is that something that wont be known till a full teardown and tank, and magna flux ?
I would guess more likely pull starting with starting fluid (under full compression) caused the bent rod, scene bent rods caused from that many times before, just an idea
I wonder how much liquid is required to hydro-lock the RD6, and whether this was natural condensation accumulation or from a leak into intake or exhaust.
Thank you for this video squatch. I know this narrow or standard gauge RD6 is a 1936 model. I was curious what year the wide gauge RD6 3072 is? Don't be pressured into taking on this project before you are completely well....6 months out is perfectly ok. This resurrection will be quite heavy work compared to the little D2 1113.
So, if you do a pull start, and have the compression release OPEN and pull it for 100 feet or so, BEFORE closing the compression release, will that “pump” out any fluid in the cylinders, then allowing you to CLOSE the compression release for a “safe” pull start? Would you “guess” that the damage to #1 is limited to the cylinder liner, piston, connecting rod, wrist pins, connecting rod bearings and hopefully “minor” scoring from circulation of debris before the engine was shut down: Oil pump? Other bearings, etc?
I know there are a couple projects in front of this cat. But one day the engine will be pulled it will go on a cart. It will be tore down and cleaned and put back together like a fine watch and the day this bulid starts to happen i will be so happy. Not that i don't like the other bulids just like the cat stuff a little better something in the craftsmanship
Squatch I really enjoy the caterpillar content Not sure if you’ve answered this question in the past, I’ve watched most of the D2 content How do you secure your crawlers for transport? Thanks

WOW, when that big old cylinder hydro locked it had to have made a violent BANG! Someone knew something happened!

As a rule of thumb, it's probably safe to practice cranking the engine over by hand 1st if it's been sitting for a prolonged period of time.
It didn’t have the hand crank provision because of the aftermarket hydraulic pump drive which was a link in the chain of events.
@@johna7661 do'h lol, he did say that....duh.
If they hadn't been too lazy to pull it with compression release first, the rod would still be okay
Love the scene with old barn in background! Thanks for video Toby.
I would enjoy seeing the RD-6 head into the shop. Thanks

I agree with the others. I'd like to see this one get back to running and greased up. Not really a full restoration but get it back in service.
That's what you call a "self clearancing" problem.

Another episode from Squatch, the tractor forensic pathologist...
😂
Thx a lot!
👍👍👍
You should see how we bend giant ones on EMD 645 engines on locomotives🤣
I had a j rod out of a 6.2 diesel that sucked in water while running. It was a neat conversation piece. Hydraulic lock on an engine is no bueno.
I'm glad you explained the condition of the engine. The still photos looked like you were caught by an F1 during tornado season!!! 😂
When that piston and rod come out they will make one heck of a wall hanger!
I really like you added metric and imperial sizes together. Really gives for us none imperial size knowers a good idea what the dimensions are like.

The rd6 rebuild would be a popular series when the time comes. It has all the great features. Carnage,coolness and the rd6 sound cool when running.
More carnage when attached to the rock crusher!!!!!
The bent rod did spark my curiosity.
I've seen remarkable strange things happen mechanically. Thank you.
Well it's looking into your next rebuild project
When you're eye is fully healed a RD6 repair and rebuild would be great 👍
I want one of those machines so bad, got me hooked back on your old "starting an RD6" from years ago.
Bang Bang Bang went the rid.
The compression of that one cylinder is huge.
Thank you for the story time
She go boom !!!
I really appreciate your explanation. The damage that results from liquid inside a cylinder is amazing. The forces inside a piston engine are tremendous. I once threw a rod out of a MM Z by stopping the feed on a hammermill it was driving. The tractor was at full throttle and I was too slow getting to the throttle. It was pretty scary.
That must’ve been a hell of a cacophony when it came apart.
You have to pump liquids the best way dzls compress air only ronrdzl
When the times comes to rebuild the RD6; that bent connecting rod needs to become a wall hanger!
Tobie you are a Caterpillar Dr
Great story

Excellent video that is what I was thinking would have bent the connecting rod. My dad had that happen to a John Deere G tractor over 40 years ago now it leaked coolant into the cylinder and he realize that and he went to pull it started and it bent number 1 flywheel side connecting rod and busted the block to pieces it became a parts tractor after that
I guess pull starting is not always a good idea with out turning the engine over first. I will be looking forward to watching this one get worked on.
It's never a solution.
Ahh the power of a John Deere 😅😅😅
Haha blame it on the John Deere! 🤣
How's your eye I can't wait to see what's in store for this crawler don't rush though because I still want you to heal up
A story well-told. Thanks for taking the time to re-tell it. Steve
as always you explain everything in great detail thank you!
Thanks for sharing.
I have to comment here, while not RD-6 related directly. It is adjacent kinda.
A while back you were talking about the difference between dozers and tractors. That dozers have front ends nearly even with or slightly behind the front idler wheel. While tractors have the radiator and more proud of the front idler.
Since then, I found myself looking harder at such and yep. Spot on true even in the larger units. It's one of those oddities that was seen but not noticed until it was pointed out.
And for how to get such a rod bent, it's a leverage thing from pull starting. That as the momentum builds in the machine being pulled, it multiplies through the drive train to the engine. Which all it needed in a cylinder was to have a small pool of unburned fuel or water that as the piston went up for the compression stroke ran into the liquid held in by the closed valves. Then it just became a weakest point, the rod at about the last third of its length. After that full compression couldn't be achieved thus a misfire for a diesel.
As long as the liner isn't cracked or the piston itself damaged, a NOS rod can be sourced. A new one machined or if really desperate, the old one straightened. The latter would need to then be fully heated then cooled slowly to get the stresses out that come from work hardening, spot heating. Downside of which would be that rod would be perpetually a risk to break at the repair point. While it may never let go with the use you'd give it. It could just as easily let go at first crank post rebuild.
Thanks for the video Toby! The forces created there are something else. Cheers
Pull start hydrolocked diesel.. That's something that doesn't happen every day.
Good video again Squatch. And I like you every now and then also make the cross reference from imperial to metrics measurements. You’re becoming an global acting TH-camr !
So what are each of these components metalurgy? Piston= Aluminum alloy? Connecting rod= forged steel? What is the liner made of? Something good if it was able to shave material off the connecting rod!
Thank you interesting. Glad you are feeling better each and every day 😊
Is that an eagle flying in to the tree behind you at around 1:15 🤔
I assume you are thinking the block can be used. Maybe just some easing of the sharp edge where the cast iron piece broke off and should not cause a problem.
Cannot imagine the footpounds of torque trying to roll #1 rod and piston around when the rod bent.
Thanks for the RD6 review I seen the earlier and the later but never the actual home coming video maybe one day I will get to it. Keep that eye protected I sincerely hope it's coming along fine.😊
Man that’s some serious compression in those engines. Can we look forward to a rebuild series on that RD6? Hope you are feeling better.
Squatch, thanks for the video. I hope you are well on your way to being on the mend. Understand you may not soon or ever get into that RD6, but if you do, I'd definitely appreciate the videos. I'll go back and watch the RD6 Playlist series, thanks.
This beast needs to be the next project. I want X231 done also, but there may be more burnout from it, if so, Crackle Jack can fill in the feed.
Time to put this in the shop and start ripping it apart!❤
Great video, thanks for the info
The forces involved in these engines are pretty big. Takes only one "mistake" in the perfect functioning grand order of things to cause a headache.
keep up the good work
Having been exposed to quite a few diesel engines over the years early Cummins had a spring loaded compression release and it was normal to pull it open start the engine spinning and release the compression release to start as this would help expel any build up be it fuel or coolant of course if there was any you needed to pull the affected headband sort the issue mainly it got the motor spinning and circulations oil before ignition

So is this the winter project? Hey, useful to get a bit of piston with a name on it.

Does playing with the RD6 rod and piston count as heavy lifting🤣. Be careful
Thank you for this video squatch. I know this narrow or standard gauge RD6 is a 1936 model. I was curious what year the wide gauge RD6 3072 is?
Don't be pressured into taking on this project before you are completely well....6 months out is perfectly ok. This resurrection will be quite heavy work compared to the little D2 1113.
So, if you do a pull start, and have the compression release OPEN and pull it for 100 feet or so, BEFORE closing the compression release, will that “pump” out any fluid in the cylinders, then allowing you to CLOSE the compression release for a “safe” pull start?
Would you “guess” that the damage to #1 is limited to the cylinder liner, piston, connecting rod, wrist pins, connecting rod bearings and hopefully “minor” scoring from circulation of debris before the engine was shut down: Oil pump? Other bearings, etc?
Nice to see the military serial number on the side of the hood. Any military contract plates left on it?
@@squatch253 Great, thank you, may check.
Great video. Is there anyway to turn up an injection pump on a d2 d311 engine to give more fuel?
I know there are a couple projects in front of this cat. But one day the engine will be pulled it will go on a cart. It will be tore down and cleaned and put back together like a fine watch and the day this bulid starts to happen i will be so happy. Not that i don't like the other bulids just like the cat stuff a little better something in the craftsmanship
Squatch
I really enjoy the caterpillar content
Not sure if you’ve answered this question in the past, I’ve watched most of the D2 content
How do you secure your crawlers for transport?
Thanks
