Thanks,
I pulled the engine and this is what I found:m38a1butch wrote: ↑Sun Feb 04, 2018 4:46 amThanks -- I too don't want to go into the transmission as my first choice. So it looks like I'll be pulling the engine to check out the clutch system. I have one nagging question though, if it is the clutch then wouldn't it also grind gears in 2nd & 3rd? Since I'm a new mule owner there's much I don't know but with guys like yourself I'll get there (if I don't die of old age first )muleman7 wrote: ↑Sat Feb 03, 2018 5:43 pmI would check the clutch disk, pressure plate, throwout bearing and sleeve before tearing into the transmission. My guess is the clutch disk is dragging when the clutch pedal is fully depressed.
Unable to shift into 1st-rev with the engine running and clutch fully depressed is a cause of:
1-clutch disc spinning while the clutch is fully depressed
2-not coming to a complete stop prior to shifting
Clutch free play before throwout bearing contacts pressure plate should be 1/2"
1-top bar of foot basket bent inward not allowing full movement of clutch pedal [likely] push in clutch and pull up on clutch cable then try shifting
2-clutch pedal adjustment not correct too much free play [likely]
3-clutch disc fingers warped causing the linings to be too wide dragging on the flywheel and pressure plate [not as likely]
4-levers or fingers on pressure plate not properly adjusted [seldom the problem]
After analyzing this I've come to the conclusion that who ever installed the clutch system prior to me obtaining the mule installed the throw out bearing in backwards causing the backside of the bearing to slide down the pressure plate fingers causing the deep gouges in each of the fingers. It's been my experience that the "flat" side of the throw out bearing always contacted the finger tips of the pressure plate.muleman7 wrote: ↑Thu Feb 08, 2018 4:16 pmIt appears that the throwout bearing failed and the back side worked back wearing the carrier fingers then the bearing froze and wore the levers on the pressure plate. You may re-use the pressure plate as the tips are not worn where the throwout bearing makes initial contact.
Best practice is replace the pressure plate, clutch disc, carrier and throwout bearing. Pressure plate and clutch disc may be reused but that is your choice. You only want to do this once.
There is a small spring that attaches to the throwout bearing carrier and input shaft cover that pulls the carrier back against the cover.

It's been my experience that the "flat" side of the throw out bearing always contacted the finger tips of the pressure plate. The picture is the exact way it looked when I removed the engine. The throw out bearing retainer is almost completely worn through.muleman7 wrote: ↑Thu Feb 08, 2018 4:16 pmIt appears that the throwout bearing failed and the back side worked back wearing the carrier fingers then the bearing froze and wore the levers on the pressure plate.

That was the problem. Somehow it was pushed closer to the neutral position and being a new mule owner (I feel a little like an ass here) I didn't even think to check that. Everything's fine. Clutch works like it should. Life is good.
