D6 9U 9808 Clutch and Tranny Questions

I would suspect the winch. That may be just because I'm an optimist, but it doesn't shift correctly, and the transmission does, so maybe removing the winch will free up the input shaft. and everything else is ok.

Could very well be as the winch is in constant drive except when disconnected by main engine clutch so if something in the winch is froze (bearing or drive gears) the whole drive line comes to a halt.

Couple more thoughts:
I would think if the winch drive had froze up solid enough to kill the tractor you would not get any backlash movement in the shaft unless the connecting coupling was loose. On the other hand locked gears in the transmission would still have some backlash as you mentioned. Either way you probably wouldn't get enough movement to engage/disengage the winch dog clutch for shifting. Just thinking........

Old Magnet,

Eric did not think that it was an oil clutch either. That is what I initially thought it was. I can't determine whether or not the winch was running 'accidently' while they were pushing on that tree and just bound the cable up so tight that it wouldn't move or what. All I know is that it stopped right there.

We may take a stab at trying to start it and see what can be done, but first we have a 14A D8 to bring home that runs.. So maybe it will get looked at in july. It also depends on what they want out of it. Free is almost too much.. It does have a nice 9' Mann brush rake, but the cat is pretty used up.

OM,

Here is a link to the pictures of the cat. I don't have any real good ones of the clutch. I dug all the crap out and then my batteries died in the camera.

Will I find a dipstick for the oil clutch on the right hand side of the cat like on most oil clutches?

Yes on the dip stick and fill plug...........but that's no oil clutch. Appears to be earlier clutch like out of a 4R/5R unit which has the fingers like the D4-7U that you mentioned. Also the early style release collar with the oil funnel drip lube that you can sorta see😄 😄

Here's a sample early clutch....still has thermite links though.

Sorry, copied the wrong page.....and it's 4R not R4 (time to quit for the night)

Thanks Old Magnet. Kind of a puzzler on the clutch. I guess maybe you can put the older one in the later cat? Too busy right now to go up and play with it... Hopefully this summer.. I can't get the gal to come up with a value on the thing anyway.. And I don't want to pay for it.. If I wanted the clearing rake I guess I would pony up some dough.. but I don't...
