Okay. So hereís the deal. On page 30 of the 1975 parts section I found the broken part. Itís one of two ďearsĒ that are on the opposite side of the chain adjustment rod. Thereís a rod that goes through the two ears. The outer oneís ear broke off down near the hole the rod runs through. It looks like the two ears and shaft locate the sprocket and maybe when you tighten/loosen the adj shaft the whole housing pivots to make that happen. Thereís no number or name for the part, although it looks pretty important. It does seem to be aluminum. Not sure what I did to break it, though.

It would be great if you have the piece that broke off.

Simple Heli Arc job, for the most part.

If you don't the broken off ear, then one must be fabricated, and this will cost you more. Find a reputable welding shop. Take it from there.

All of this of course after your remove the front axle housing for the repair.

you got that correct. the housing swings. ( yours used to) it is the course adjustment for the track, and the fine adjustment for the drive chain.

basically the drive chain tension is set, then you go to the back of the machine to fine adjust the track.

when owners don't go to the machine and spend a period of time figuring out how what, effects which, when and where, Items can be forced to failure.

there is some pretty good engineering and unique ways of getting the machine to work, stare at it a bit to understand the (how)

those aluminum pieces can get hurt pretty easy loading a trailer or hitting a stump.

I have a broken one I will post a picture of it to see if it is what you are talking about.

of course that will be after work tomorrow 5 PM central

sorry for the delay.

Pre-retirement has ended for me temporarily..... I am back to work.

I think you are describing this part.

the power comes to the track drive sprocket from the shaft spinning in the center.

the aluminum housing rotates on the mounts tensioning both the interior drive chain and the outside drive belts........

Yep. I believe the broken ear is on the inboard end. Broke off just above the hole. Couldnít find the little piece. Still not sure what caused the stress there. I was doing a careful (I thought) 180* turn. Maybe it was loose somehow?

At this point I would consider trading my two machines for one good, reliable one. I like the idea of owning two but realistically I won’t be able to fix or work on either until I get my hangar/shop built...probably a year or more. I’d rather have one that works now. Any takers?

I doubt you will have any trouble finding someone for that trade. your machines look desirable.

I like the ambulance door on the white one.
