More clutch issues

Hoenes · May 13, 2016

I'm finishing up my power unit. I took off the original clutch housing, torque tube, and belt pulley. I installed a "power unit" bell housing off a combine. This changes the set up from input shaft, to an output shaft. The clutch worked fine before. The belt pulley would come to a complete stop pretty quick. Now, the "output" shaft wants to keep up with engine speed, when the clutch is in. I can stop it by letting it drag down with a LONG 2x2, but as soon as I take away the 2x2, it gathers up engine speed again. Is this because there is no load on it, or do I need to loosen up the clutch adjustment a little? I hate to start messing with the clutch adjustment, but I don't want to burn up a clutch either, when I put a generator or "whatever" behind it. Sorry for long post.

Does it have any free play? or the pilot bearing may be a little snug.

Yes, it's completely loose when the clutch is pushed in and the motor is off. It spins freely. I need to check the serial number cut-off to see if it's a pilot bushing, or a pilot bearing. I'm thinking a bushing would drag more than a ball bearing. The agco pdf manual said if your in there, to update the bushing set up to the bearing set up. So far, I haven't had the need to. By the way, it's a wd 201 engine. The power unit bell housing works on either wd or 45.

If the Pilot bearing had any grease in it when the shaft went in, it should be good for many years of use, be it bearing or Bushing..

A Pilot bearing should not cause an Input shaft to spin..

Have you looked at the Pressure-Plate "Fingers", to see if they are all 3 set alike..?

You can tell by locking the foot clutch in the disengaged position and measure the width between the Flywheel and the Pressure Plate at each approximate "Finger" location..

All should measure the same..

Bushog, I will check those measurements. Unfortunately, not a lot of thought was given to the clutch access area when we built the frame. I used the original tractor side rails, and elevated them above a "skid frame" made out of wide channel iron. A cross member sets aways below the access plate. Wrenches are no problem, but visual is. Odd thing is, with all the original parts, the clutch adjustment was fine. Maybe the drag of all the gearing in the torque tube and the weight of the (wide style) belt pulley (on the side rail) was enough drag to stop rotation when the clutch is in. The only purpose of this clutch, is for "start up" only, so the starter don't have to drag along the generator or whatever I end up putting behind it.

The pilot bearing turns anytime the engine does, so if the input shaft fits too tight in it, it will turn right along with the engine, even with the clutch held down.

You think it will after being in there anything more than a short time..????????????????????????

THINK...!!!!

Don't need to think about it, seen it and know it can happen, not only on tractors but cars and trucks too. If the shaft fits any kinda snug, or is long enough to hit bottom, its gonna turn with the engine.

Cole, Yes I have seen that too, even after operating for quite some time. Had to split the tractor, it would not loosen up.
