886 International clutch

M Nut · Jul 13, 2011

Tractor seemed like the clutch was slipping a bit, (but couldn't smell clutch) so I went through and adjusted the clutch and the TA according to the service manual. Seems to have improved the slipping , but now when I push in the clutch to stop movement of the tractor, the tractor almost stops, then suddenly has a quick lurch forward with a knock type noise, then comes to a complete stop like normal. (If I pull it into neutral as soon as I depress the clutch, it doesn't do the lurch or knock) Any ideas as to what to try and adjust next? possibly the clutch brake?, although I did adjust that when I did the clutch and the TA, but is that where I guy should start checking again?

I have my doughts that it was your clutch thats was slipping, Its your TA. The lurch forward and the knock is being caused by the TA, that is the sprag clutch that is causing the movement and the noise. I don't know enough about them to describe better but im sure someone else can. But i am certian that your in for a TA job.

Even on the direct (high) side? The TA functions just fine otherwise. I use it all the time switching from high to low and back into high again. Not doubting your thoughts, I just was under the impression that if a TA goes bad you can still use the tractor just fine, but have to leave it in Direct drive?

I bet it doesn't do that if you have TA lever back when you push clutch in. Sounds like you are releasing the direct drive
TA clutch before the main clutch releases and it is down shifting ito TA low side but it sprague slips some before it takes ahold. Try readjusting dump valve so red light gots out just a bit before main clutch engages. If red light isn't working, run up a grade, adjust so with tractor creeping backwards it stops moving back just before main clutch engages starting to pull you forward. Do this with ta lever ahead in Direct Drive. Also, make sure you haven't given clutch too much free play trying to overcome worn clutch slipping.

Yes, it does do it with the TA lever pulled back. It does it with the TA in either position. Sounds like i may have to go back and re-adjust everything again? I did it all twice, but something still isn't right. Fixed one problem and created another!

Yeah, it's the TA. Mine started out with the little lurch and clunk noise just like you describe, but soon, JUST before all movement stops it felt more like being rear-ended by a small car accompanied by a sound like dropping a large steel ball on the deck of a battleship.

Yes it will still do this in DD. Your TA will still shift fine but its your sprage clutch that is getting weak. It will run for awhile longer but it is on its way out. My 1468 does what yours is doin but not near as bad.
