Transmission slippage on 1086

nathan · Apr 30, 2014

I"m new to the tractor and know its been sitting unused in a shed for appx. 10 years. Owner died and we found it so have no history on tractor. Drives but does not have very much spunk and slips, slipping gets worse the longer you drive and it doesn"t make much difference whether or not TA is engaged. Looking for the simple fix if any, but not afraid of splitting and repairing anything necessary

Sounds like the clutch is 'gone'. Split it and replace it.

Good news is, you found out why it was parked.

Well before i would start spending money first i would be looking a clutch adjustment . dump valve and CAB mounts and MCV pressures . Now not sayen that this is the cure all but this is where i would go first . And the one thing that really gets me is to split one and stuff a clutch in and ONLY a clutch and two weeks later the T/A takes a DUMP.

I agree with DeltaRed. I got a 1086 that had been parked in the weather about 13 years last year for almost nothing because "the T/A is out"... when I got the tractor to crank up, the clutch wouldn't budge and you had to yank the shifter into first gear, but the T/A would shift hard enough to shake the front tires. Long story short, when I split it, the clutch was rusted to the flywheel- new flywheel and clutch, I was back in business under $1000.

As for me if it was a stuck clutch i still would not have split the tractor . I would have put 1/4 inch nuts under the clutch fingers and unbolted it from the flywheel and popped it loose but it back together and do a little clutch slippage and run it like i stole it . It would have self cleaned it's self . Now as the other boy's problem his clutch is slipping , so before the splitting stands come out i like to look for the reason on WHY .and to see if i can SAVE MONEY . But hey what do i know .

My 1206 started slipping a couple of winters ago. So we split it, clutch was worn but should have slipped. Well new clutch and facing the flywheel DID NOT if the problem. New MCV hydraulic pump did. old pump wasn't building enough pressure at low RPM's to fully engage the TA.

Yeah, I don't know why most everyone is saying clutch, clutch, clutch, because that is the last thing that will slip on a tractor like a 1086. My money is on a bad TA. They ran it until one side went out, then ran it until the other side went out. On hydraulic TAs, when one side goes the other is not far behind.

The "cheap" thing to do right now is not turn a single frame bolt. Check the adjustments on the clutch and pressures on the MCV so you get a better idea of what's wrong, like tractor vet said. Splitting one of these is quite a bit of work, and no fun. You don't want to do it on a guess.
