News: 10/5/12 - All new members are REQUIRED to fill out the signature section of your profile. Otherwise, you may be deleted from the forum. This is to help me determine if you are a member or if you are a spammer. Thank you.

9/22/12 - I ask that you please add a signature line to your profiles on the Cletrac Forum to help me to determine who is spam and who is not. You don't need to drop everything and do this immediately, but please do it when you get a minute and you are visiting the forum. Just go to and put something in the signature area. If you no longer want to be a member on the Cletrac Forum, please remove your membership.

8/10/11 - Added a new board: Trucking and Hauling

5/30/11 - Just added several new pictures to the Photo Gallery, including several Alfta Track OC-4 working in snow logging, several from the Chicago Road Show, and some from a logging show (not all Oliver/Cletrac). All these pictures are from around 1963 and were scanned from old slides given to me by my late friend John W. Davis. Go to the Photo Gallery and click on "NEW" to see these pictures. Quality is marginal, but I think you will enjoy them.

2/13/11 - Just added a new board "New members introduce yourselves here".

Folks, I just added a new photo gallery where you can upload your own pictures with descriptions, etc. Right now this is in the beta testing stage to see how it works out. Give it a try, but please keep a backup copy of your pictures just in case we decide to use something else. I would prefer you use your real name on the photo gallery, but if you really don't want to, please use the same username as on the forum. Please put your images into the proper categories and take care when your write out your descriptions and image names so people can search for them. I am learning this as we go. At least at the beginning, I have it set up where the administrator has to approve members. I am afraid we may get porn spam in here if we leave it open. To get to the photo gallery, use this link:

Folks, when you join the forum, or when you get the chance to update your Profile, please be sure to put your location and interests. Filling out your signature would help as well. I've been getting some spammers joining and posting links to sites that are completely unrelated to Cletrac or Oliver, or anything to do with tractors. It would make it easier for me, as well as all the other members, if you guys would put your location and interest in your profile. See

Thanks Blake, I'll use caution then, probably leave it as it is till I have to use it.

I reckon I'm more liable to damage it by over filling that running it low, since the average mileage on the other three I've found is under 200 miles from new.

Got a Parts List, but no manual, unfortunately.

Thanks Blake, always good to know.  I can find something locally that will do.

So, just pour it in the fill elbow then?  Take out the rear plug for a level, or just use the fill elbow?

Thanks again.

Thanks Matt, I don't think standard bits would help - unless they happen to look like that image above.  I think Gil is short of those conical housings and the driveshaft / sprockets.

On another point, I've pulled the cab and drivers compartment off mine to reveal the differential  I can see a fill / level elbow right front and what could be a level plug slightly lower down at the rear;

There are plugs at the same locations and heights on the other side, without the fill elbow;

... and I think the plug at the top left is just an end cap covering the end of the operating lever shaft.

Since all the remaining T-36s that have speedometers seem to show less than 200 miles, I'm assuming the diff will be fine and just need topped up.  On the assumption that the diff is internally the same as the MG military unit, how much of what lube do I put in the fill elbow?  Do I take a rear plug out and just fill it with gear oil at the front elbow till it comes out the, back, then stick the plug back in?

I have no military manual info for the MG differential, and dont want to do something extra-stupid like put oil in a port that is access for brake band adjustment, or whatever.

It turns out that another T-36 with the Cletrac diff is in Polson, Montana, at Gil Mangel's Miracle of America Museum.

Gil is stuck with the restoration of it, as someone took the drive ends off the differential and they got lost.  I still think that the drive outpus from the T-36 diff are pretty much the same as the MG1 and MG2 units, so anyone in the US with a broken differential and a pair of drive ends they are never going to use?

That image is the drive ends on my T-36.  The Parts List does say it is an MG-type differential, so I'm hoping someone here can help.

Thanks to Matt Rimmer for pointing me at this site.  My T-36 Iron Fireman is supposed to have a Cletrac model MG differential, but the control levers and ratchets don't look anything like Matt's.

Anyone here ever run across another T-36 or know anything about them?
