Cletrac AG6 H

[thebebop]

Hi all

Can anyone supply me with info on a tractor I just purchased? It is an AG6 H and the Serial number is 3X1906. I'd like to find out the year, type of engine (casting number 15986) and any other important data in case I need to find parts. Right now it runs great, tin is complete and near perfect and under carriage is good. Paint is weak but just adds to it's character : ) It has  a Heil 8' Hyd Blade.

Last question. It currently has the rubber street treads on it (bad shape) but did come with a complete set of dirt treads. Any suggestions on an easy way to remove the old rusty bolts in order to swap them?

Thanks!

It is a 1945 model. If the orignal engine it would be an F-226 Continental which makes finding parts fairly easy. Most Continental casting for those engine start either F400 or F600. Then there are more letters and number. Questions?

Ok, is there any way to determine by sight if the engine is a continental ?

the continental is a 6cyl flat head engine and if it has a dist. ignition ,the dist. is in the center of the head ,the head is held on by a large # of studs with tall nuts on them . there should be a small machined off area on the side of the block at the top that has f226 stamped in it . to remove the pads try a impact gun and if that will not work use a torch and cut the bolts but be careful since there is gas close by . it might be best to loosen the adjusters and knock out the master pin so you can do this with the tracks removed.

Thanks ya'll, I'll take a closer look at the engine tomorrow. It is definately a 6cyl flat head. The distributor is in the middle of the head but towards the back of the engine. I'll post what I find and maybe that will help to verify the type.

The distributor drive is next to third main bearing. I was also going to mention some ofthose have a magneto but since you mentioned distributor that solves that problem. The AG-6 came about because the goverment would not have any OO series Hercules because of the war. So the AG-6 was then made with a 6 culinder Continental untill the end of its production. Questions?

From your description it seems to be the Continental.  Does the manifold have "Cletrac" cast into it?

[walter hudson]

sorry, i should of been more specific, the distributor is between the third and forth plug.

[walter hudson]

oops , the dist. is between the 4th and 5th plug, also look for the id plate on the left side lower front (below generator)

[thebebop]

I couldn't stand waiting until tomorrow so I took the good ole flashlight out. It does say Cletrac on the manifold and the distributor is set between the 4th and 5th spark plugs. There is a small machined off area one the left hand side of the block close to the top with the following numbers: 15986

The head has a lot of bolts on top with standard nuts...not what I'd call "tall nuts" The head also has "firing order" and numbers after that cast in raised letters.  Above those raised letters are more but could not make them out because of other items blocking the view. There are numbers on the lower right hand side of the block which I cannot make out either but will attempt to paper trace them tomorrow.

Torch the bolts off, but as the wise man previously stated, be careful! Don't think you're gonna save too many of them, for you my Friend are dealing with a piece of heavy machinery AND NOTHING IS CHEAP!! If you are not prepared to spend LOTS of money than perhaps another hobby would be more suitable for you. Forgive me if I sound snooty.

[thebebop]

Yep you sound pretty snooty : )  I don't mind spending money on my equipment if needed. I figured most if not all of the bolts for the track pads would have to be replaced so torching them seems to be the ticket. Nice thing about this tractor is that for the most part, it seems to be bullet proof. She's a tough old bird for sure. Wish I could say that for my Bobcat and old M & M chipper.

I've spent almost as much on those 2 in the past 2 weeks as I did for the whole Cletrac. I've worked the Cletrac twice as hard and have spent zip on repairs !!

I was figuring on selling it once my project was finished but now I might just keep it.
