- Now that I know my Coleman aircraft tug will work, its time to get it working better. I replace the broken windows, drain the gas out of the brake booster, and finish up some odds and ends. Now it is a turn-key, operational vehicle, and great for pulling stuff around the yard.

I love this guys content, he is just so--- straight forward, and he talks about everything he does.
I like.
You are a good problem solver. We need more people like you in the world.
We had a Coleman tug very much like this one when I was in Vietnam in '70-'71, in a Chinook helicopter company (271st ASHC Innkeepers) at Can Tho Army Airfield. I think ours may have been a bit newer though as it looked just a bit different as I recall. (50+years ago) It had a button under the front of the shifter knob that acted as a clutch when shifting. (Don't now how that worked, all I did was drive it from time to time) Those drive axles look to be the same as the ones that International Harvester used on the front of their 4x4 and 6x6 trucks in that time frame. It would steer with the front axle, both axles , or crab steer. I always thought those tugs were pretty cool. I saw one at a truck shop in K.C. MO. about 15 years ago, looked just like ours. Brought back a lot of memories as did this one. Dave
Thanks for sharing, this one used to use the button under the shifter. It is some kind of fluid bypass for the torque converter that unloads it. On this one, its bypassed with a hydraulic valve. I had to re-plumb it in the first video to get it to drive, but it works reliably now.
Hey brother, I was Navy, about 20 klicks up the road at Binh Thuy. Welcome home.
Worked in the electric shop during that time frame. One of the two LSI civilians.
@@LowBuckGarage did yo tighten up the loose bolts on the hydrovac unit? becaouse it seems like normally they used double bolts for londing vacuum chamber, while you're holding it 1 of them was missing and other 3 seemed like very loose. 12:43
Great content. I appreciated your logical and can-do nonchalant attitude
Thanks, glad you enjoyed it!
1968-69 Mather AFB Ca, Aircraft mechanic towed USAF T-29 aircraft 29K lbs with a Coleman tug. fond memories enjoy watching low buck garage.
That takes me back 31 years to my Air Force days.
Regarding the door glass removal and replacement:
Remove the inner door panel and examine the windows run channel. It is what the glass contacts as it slides up and down. You may notice that the welded channel leaves the run channel exposed and the inner panel appears to have a matching piece to trap the run channel in place when everything is assembled. If the run channel has a joint between the upper and lower sections just carefully pry it away from the steel channel thats welded to the door body and it will allow you to swing the glass free of the foreward section of the run channel. If there is no joint, the whole run channel should be loosened and slid down from the top to gain wiggle room to work things loose. The old run channel may just be stuck in the welded steel channel or someone may have glued it in place.
Thanks for the info, it could save me a lot of effort. I'll look for that next time!
I always thought it would be cool to make an awesome snowplow machine out of one of these.
Good idea. I have one here. Aaaannd a 10' Meyers plow. Gassers start easy in cold weather (bonus)
this man is just fantastic
You certainly don't see one of those everyday, and you're certainly don't see a half track everyday either. That vehicle certainly has a lot of torque. Great job 👍☮️
Thanks!
Don’t remember what TH-camr recommended your channel but I’m glad they did. Subscribed and am binge watching.
I look at your videos as a great source of technical information, as well as a hotbed of fantastic, economically responsible, and environmentally sound solutions to automotive problems. I really like the boat tank idea, and I may use that on my old car. I patched the tank, but my patches may not be holding up so well. No need for a 16-20 gallon tank, either, because I only drive it occasionally. I also really liked the info about the alternator pulley size. The info on the power brake booster is also useful, as I am presently helping a friend with a similar (but smaller) booster on a 1955 Cadillac. Here's a tidbit that you might find useful, too - my Garmin NUVI GPS will actually operate on 6 volts! It's in my old car right now, because the speedometer calibration is off and I was concerned about driving fast enough on the highway without over-revving the engine. The plug for the GPS has electronics in it to reduce the 12V to 5V, which the GPS uses. Evidently, the voltage regulator is capable of maintaining a high enough output voltage with only 6V going in. I simply select the speed/distance screen on the GPS when driving.
that gas tank looks just like one I bought from a military surplus yard in Utah and installed in my motorhome that I built on a international ton and a half flatbed truck chassis ...what a project that was ..!
That would make an absolutely killer offroad tow truck
Love the sound of that Chrysler. Mopar used that engine from 1935 until 1973. A real hammer.
now we got these super advanced pieces of garbage that dont last no more than 200 thousand miles....and cant or isnt worth repairing because you cant find parts for them*incorporated obselecence.
I put a 1948 Dodge Power Wagon panel truck back on the road. It was an ex-Coastguard radio truck. Sprung for 5 tons, 4WD, 4 spd with a Granny low, lo/hi range, PTO Winch. It was a beast to drive but in compound low it could just about climb trees. There's a mad joy to these cumbersome old beasts.
We had one of those Coleman guys assigned to our CH54 Skycrane helicopter unit. Those weighed 20500 lbs empty. It was not very good for maneuvering a giant helicopter in right quarters but if we had snow and ice it was great ( we had tire chains too). With a blade on the front it was a good snow plow truck. Ours had a Chrysler 413 instead of the straight 6.
Where else are you going to see someone trying to pull a half track sideways?
my first time watching you and have to say you are amazing. I love the way you think and work WOW.
Thanks, I sure appreciate that!
@@LowBuckGarage your welcome and God bless you
Thanks for sharing buddy keep up the great work🦅🇺🇸🏁😎
Thanks 👍
@@LowBuckGarage 🦅🇺🇸🏁😎
Can’t believe how smooth and quiet it runs. I think you should try and pull a 3 bottom plow with it 👍
Way cool, unique vehicle. Great job!👍🏻👍🏻👍🏻👍🏻👍🏻👏🏻👏🏻👏🏻👏🏻👏🏻⭐️⭐️⭐️⭐️⭐️✅✅✅✅✅
Comforting to know that you are cautious, following alll regulations and creating a safe space! From Canada.
I could see this thing with a full-blown towing boom thingy, rescuing folks from off-road shenanigans. Or something like that. Lots of fun in any case!
You have a good vision, I'm going to go that direction with it next!
@@LowBuckGarage Awesome!
@@LowBuckGarage I was going to suggest a CCKW and oilfield “gin pole and chains” style frame and a harbour freight budget winch.
Had a 47 Dodge dump truck with the filter for the hydrovac in the cab under the seat (lots of clean air under there!). You could hear it sucking air when you stepped on the brakes. Friend had a 70 something Chevy and the filter was on the firewall. I imagine the reason for remotely mounting the filter was to keep it from sucking in moisture from road spray when driving in the rain.
I like how you keep you cool. One problem at a time. When the fan hit the alternator. I just thought ffffffar out😂
Good show plenty of good information
Thanks!
Another great video! As far as the alternator goes, I worked in an auto parts store right out of high school. I used to re clock alternators quite often. IIRC the shaft is usually pressed into the “front” half of the shell. I don’t recall ever being able to remove that portion like yours did. Something does seem off. If you re clock the rear half of the shell and don’t pull it off the stator, it’s pretty simple. If you happen to pull it, you have to use a couple of paper clips to hold the sling loaded brushes in place for re assembly.
A very cool, fun truck
If that tug had a large boom on it from a service truck it would be really cool for yard work, pulling engines, moving equipment etc.
That's exactly what I'm thinking. Working on it right now...
I Love this Truck! ❤
this channel is the best thing
Doing a hose over a hose as needed, I've had the best luck and longest life with this method bonding the two with tire patch cement (rough it up and glue it up like you would an inner tube)
That front bumper makes it handy as a portable anvil.
Great build! Considering how sturdy those tyres look, you might try to let some air out of them, to aid with traction 👍
That brought back memories to me are used to use those to tow F-4 Phantoms at Nellis Air Force Base in the late 70s early 80s memory serves me correctly they had a flat head six-cylinder Chrysler
When the plug blow off was epic 😂😂 you are awesome !!
You are have to much fun with the truck!
Nice truck to put a blade on and in the back put a crane
I enjoyed this
Perfect for stump pulling!
Powerful old beastie
That tracked vehicle offers a challenge going sideways.
It would make a great yard truck .
Job done
U r a genius 😍😍
I really liked the trouble shooting where it is like real life, a 5 minute job turns into a 3 day affair, and one thing leads to another.
When you did the half track towing, side, you would of been able to do it if it wasnt for the soil/gravel where you lost grip on those 50 year old tires....
I look at one on facebook for sale, looked interesting for a daily driver. with todays driver, you need a bumper and heavy machiinary just to get around anymore safely...
Stay safe working on those things...Thanks very nice video.
Thanks, glad you like it!
I live in Nova Scotia, Canada, and let me tell you; if you decide to sell that thing I'll have it shipped up! That would be the perfect snow plow rig for my subdivision.
Now clean and paint
Awesome
I bet a A frame you can adjust the angle on and a heavy duty winch would make that a good tow truck strong enough to get semis or similar out of ditches and/or mud in your area making it possible for you to make a fiew extra bucks to pay for your projects, with that 2 axle steering it should be a joy to maneuver while getting people unstuck (just don´t forget to get good snow chains for all wheels). Good luck on future projects.
Hit the caps with 420 lap caller good.
I came up with your channel couple of days ago and i’m addicted. I’ve watched a few videos and only thing i would like for you to do differently is the alternator pulley; why not put original into lathe, cut in half and add a spacer. Wouldn’t be in anyway better, but lower buck.
Nice channel and i thank you for it. Greetings from Finland
Could be a fine yard wrecker - and easy mods to make it happen. A PTO and winch would be very nice along with a boom and strut system.
or a realllllly good grocery getter....talk about safe.
A Holmes lift bed would be nice
Thanks again mate for your time, I am watching out of sequence as I only recently discovered your channel and I'm happy I did. Looking forward to catching up on any previous projects. Nice half track, is that what you call it? Not everyone can say they own one of those. Bye now see you next time.
kinda wish the old panel would still cover the gastank, maybe with some hinges to make it easy to open and close but yea, not just an open red gastank
That window looks to be same as what Grumman step van uses.
Towed a lot of f-16s around with that mb4
Overkill...lol. We towed F-16s with bobtails at Balad...lol. Not saying we didn't tow with a similar beast also...but our big tug in Balad broke (go figure) so we used bobtails. :D
Next time pulling a stump out, put a steel rim next to the stump and run your tow rope over it to your vehicle. You will get way more power and it will lift the stump up and out instead of over thru the soil and roots fighting against you.
Doesn't hurt to throw 2 bungees on that gas tank. Also, I would try to make that panel be easy removal. Maybe some nutserts and thunbscrews.
I want one!.!.!.!
Look at the top of door should be screws t0 take the top off to change the glass.good luck
Impressive. Just what you need for pulling the shopping home from Walmart!😂😂
I was thinking using it to plow making tight corners and things like that. But you may not be in an area where it snows.
18:38 An A section belt in B section pulleys.
24:16 Just bend the fan blades forward a little.
Do you have any idea where that tug came from? It is identical to the one we had in Montana. We had a welder in the back. I almost believe it might be it with the glass and back counter weight removed.
Brought back tons of memories! I drove those while towing RF4C jets in the air force for several years. Every one had the engine speed governed to keep us lead feet drivers from speeding. I was wondering if your was governed when you first got it. What is your background?
Endless possibilities with that piece of testosterone!
We need to help get this great creator up to 10k plus subscribers.
That would be awesome, if it does happen I'll come up with a special video!
@@LowBuckGarage Make some shorts. I think that will help.
@@tihspidtherekciltilc5469 Thanks for the input, I'll give it a shot! I've been saving an alternator rebuild as a piece in a longer video, will try uploading it on its own.
I would love to see that half track thing motor around if you havent done it already.
Love your project! Would it go faster if bumper was removed?
👍👌👏
Love your channel, just going back and catching up on some old videos. My experience, one of the challenges with towing something with a strap is the strength of the strap versus the weight of what you’re towing. Your strap appears to be a sling strap that we would use to sling load Equipment underneath helicopters. But just curious what kind of strap you were using? What was the strength for it? Maybe somebody else saw from the video?
You might want to build a A-FRAME stump puller and you will be able to pull stumps or even the whole tree out. just look on you tube for A-FRAME stump puller .
Man I love the content been binge watching because you look familiar to me ... if the name Tom Calanan Rings a bell im sure you will remember me... Anywho keep on doing your thing
Sorry, the name doesn't ring a bell. Hope you keep watching anyway!
Onward!!
That Coleman tow,,do they use this in Airports? Looks like a Fisher Price toys for adults,,when I saw it pulling and slipping,,I thought. The tires were gonna blow,,they look like slicks
Bet the tank is welded in 😂😂😂
Talk to Rory at moab motorsports aka trailmater about the tow truck Olympics!
I really enjoy your videos! I'm curious about the 4x4 motor home in your yard. Is that one factory? I actually ran across a late 70's Motor home that was factory 4x4. Can't remember the manufacturer but it had a cool 70's name and data plates on the side. Anyhow, take care 🙂👍
This one is not, I swapped in the drivetrain from an '94 Dodge. I wasn't happy with the front end, but just picked up a different dana 60 that should make it all work.
@@LowBuckGarage oh ok. Cool 🙂👍 I hope it works better for you. Thanks for the reply 🔧
😁😁👍👍
About the gm alternator issues charging. I know on some of the old tractors you have rev the engine up or use a separate wire to excite it to start it charging. Have you seen that before?
I've got a plan for this one that will need good charging at idle, so I needed to go the small pulley route to get the alternator speed up. It will come in handy soon!
Looks like the booster was used as a reserve tank.
You needed to pull from the bottom, your pulling it into the ground, if you pull lower down, you'll be pulling up, it won't dig in. Cheers.
I wonder if you could find an original or re-popped 1000lb rear bumper. That might eliminate the rears bouncing and spinning...which I never ever saw when I was driving them in the late 80s. Of course, pulling 50,000lb aircraft on a concrete flightline with wheels under the aircraft is a lot different than pulling a halftrack sideways through the sand...lol.
I'm also wondering about the shock absorbers. I'm sure they're completely worn out by now, and that might let the axle bounce around too much. Though it works great towing stuff in the normal direction!
Wow that hurt ... yea i do that kind of thing alot 😂😂😂😂😂😂😂
On your hydraulic line next to your alternator why not use a street l instead of a pipe with an elbow to give you more alternator adjustment.
Is there a centre diff , if so you should have locked it to stop the hopping when towing the 1/2 track.
There is, but I'm not sure if its working properly. I did engage it, but it didn't seem to make much of a difference.
What axles does the Coleman have under it? 4 wheel steer is neat!
I believe Coleman made their own axles, they made 4x4 conversion for other manufacturers also. That 4 wheel steering is great for getting into tight spots.
I'd wager that with a big huge slug of a concrete block for weight up in the bed, that thing could'a moved that half track. Just seemed it didn't have enough tractive weight.
Need too find an old fork lift mast put on the front an 3 point on back.
Stump was pretty rotten. No contest for the bad boy.
Thre G M ALTERNATIR YOU HAVE.....IS THE EASYEST TO REASSEMBLE ALTERNATOR
THEY EVER MADE.....THE TRICK. IS TO PUSH YTHE BRUSHES IN AND INSERT
PAOERCLIPS IN THE HOLES TO
HOLD THE BRUSHS. IN....THATS IT
....PPOP IT OPEN AND LOOK....IT LIKE LEGOS
Is that a crack on the axle tube that closes up while pulling @30:46?
I'd never noticed that, next time I crawl under it I will definitely look. Thanks for giving me a heads up!
Disappointed you did not mend hydro vac, keep up with the content
Yeah, me too. I spent a while trying to hunt down the little rubber bits it needed, but came up dry on two critical seals. Without them it would fill with brake fluid; they were really bad. I have all the parts saved, so when I do come up with those parts I'll rebuild this one and put it in another project.
wow that bean counter or engineer responsible for that bottom manifold hydro vac line must of come from a mom who smoked and drank when she was pregnant.
WHAT ENGINE DOES IT HAVE ?
I just bought a Coleman MB4.... I need a master cylinder.... Any chance I could get the Napa part number?
The master cylinder is a NAPA number NMC M661.
Is that a 4x4 rv in the background :)
Yes, its got a '94 dodge 4x4 drivetrain swapped into it. I built that way before I did video, though.
