Clutch and transmission problems with Ford Jubilee

HanknotFrank · Sep 26, 2023

Recently acquired Jubilee had been running pretty good after help from this forum for wiring and alternator problems.But now I can only change gears with the tractor not running. With it running it scraps and is very hard to get in or out of a gear. I read most of the posts on this site regarding a stuck clutch that is rusted. I assumed that was my problem but before doing anything I looked in my manual and it said to stop tractor before shifting gears which of course I do but I thought it meant to use low idle speed. Today I cranked it up and made sure I was at low idle speed when changing (and of course stopped) gears and it went into gear easily several times but later when tractor was warmed up the problem returned and I could not shift into gear. Thanks for any help.

It sounds like the clutch is not stuck if you were able to shift it in and out of gear when stopped an idle. Check the linkage for excess wear in pins and pin holes. Then check to see that the clutch is adjusted per the manual. If you have too much pedal free play it might not be fully disengaging the clutch.

Check the free play adjustment on the clutch pedal. I don't know the
specs, but there should be some movement at the top, maybe 3/4 inch or so
before you feel the spring resistance of the clutch. Too much play and
the clutch will drag, never fully releasing. Too little will cause
premature wear on the release bearing and possibly clutch slippage.

Also check the transmission oil level. Being low on oil will cause the
transmission to continue to spin after the clutch is disengaged. The oil
acts as a damper to bring the transmission to a stop quicker.

The transmission has no synchronizer rings. It must stop spinning before
it will go into any gear without grinding. They are tough, some grinding
is allowable, just don't make it a habit or get too forceful with it.
Trying to shift with the engine above idle or while still rolling will
aggravate the problem.

If none of this helps, it may be time for a new clutch. A worn clutch
disc is sometimes slow to release. So can a warped or failing pressure
plate cause release problems..

In addition it possibly being out of adjustment, the clutch disk needs to slide freely on the input shaft splines. If the tractor has been sitting for a while, there could be be rust on the splines which prevents the disk from backing away from the flywheel.

If the tractor stops moving when you press the clutch, you know the pressure plate is working. Try adjusting the pedal so there is NO free play. If that works add some free play until it drags again, then set the free play between none and where is starts to drag.

IF you still have the problem with no free play at the pedal, I think you have a rusty input shaft. On my 860 you can see into the bell housing without splitting the tractor. The steering gearbox assembly is bolted down over a nice big hole in the bell housing. It is a pain to take off the sheet metal etc. But is is easier than splitting the tractor. YOU may just need to spray a little PB Blaster on the input shaft.

Good Luck
