Clutch Question

Mnethercutt · Dec 31, 2018

I’ve just finished reassembling my 1010 and am concerned that the clutch is not going to fully disengage. I haven’t tried to drive yet or even put the tractor in gear while running, but I cannot adjust the pedal to have the 3/4 inch free play. Adjusted as far as I can, I have about 1.5 inch of free play. If I press the pedal down and engage the pto, I can spin the pto but I hear the clutch spinning. When I reassembled the clutch, I just put everything back together and bolted the pressure plate down tight. I used the shaft to try and keep the disc centered but just want to make sure I haven’t screwed something up before I burn up a clutch disk.

Thanks!

With PTO engaged, the clutch pedal depressed, you can turn the PTO shaft, and hear the clutch turning inside the housing. Is that correct? Is it turning easily? If the pressure plate is releasing you should be able to turn the PTO shaft and since the disc is just floating on the shaft you may hear the clutch disc scuffing the pressure plate and/or flywheel as it turns. If you let the clutch pedal up can you turn the PTO shaft?

Did you set the pressure plate finger height after installing the pressure plate? I don't have a 1010 manual but know there is a procedure for many JD's to set the pressure plate finger height when a clutch is installed and expect your model is one of those. This is done using the specified JD gauge for that tractor and clutch (some folks have come up with other methods to check the height instead of purchasing the gauge). The fingers are supposed to be within about .015" to .020" of each other as well, if I remember right . Since the throwout bearing operates the pressure plate fingers, finger height can effect being able to get the clutch pedal free play right.

It turns easily with the pedal depressed but if I let it up it doesn’t turn.

I did not adjust the finger height. I saw that section in the manual, but it sounded as though it wasn’t necessary since I hadn’t disassembled the pressure plate, plus I didn’t have the tool. I’m reusing the same one I had when I took it apart.

You will likely be ok with the free play you have as long as it disengages. Wear will normally reduce free play, so you shouldn't have to adjust free play for a while.

To be "devil's advocate" for checking/setting the fingers, several things can come into play. Do you know it was set up properly the last time a clutch was installed? Do you know the clutch disc you got is the same thickness the old one was originally? Have the flywheel or pressure plate faces worn away some or been surfaced since it was last set?

It is always a crap shoot re-using the old pressure plate. How much wear is in the pins, pivots, and holes? Are the springs still up to spec? What is the condition of the plate's disc surface? That said; I have had a new, not rebuilt, pressure plate fail in a plow truck. It went in, adjusted easily, and worked fine; then it broke a finger within hours after it was put to work. You never know. JMHO
