108 with brake on PTO

BigB87 · #1 04-01-2015, 07:08 AM

I rebuilt the clutch in my 108 and it doesn't do as good now. It had 2 disks before i rebuilt it and only put one back in. Would this cause my problems? I know when its engaged it shouldn't slip much or at all. I can put a belt on it and hold it still with my hand (I know dangerous) but its driving me nuts. I have my tiller mounted to it and have to ride the clutch along with being in 1st in low range to till some soft stuff. But should I put 2 disks in or just leave the one?

I used two discs in mine. I had the opposite problem with mine, it was difficult to disengage. Sounds like you need to tighten the three adjusting screws tighter.

Well when i do that it stays engaged and can't disengage it at all

Two friction disks? Or two springs?

Adding a second friction would do nothing for holding power. Not unless you added a steel disk that is connected to the PTO (like the rear steel) between them.

Did you install a new spring? You sure all parts are correct? Did you use the gauge to adjust it? Not pointing fingers, but I'd say you either installed incorrect parts, or didn't assemble it right.

Well ive readjusted it 3 or 4 times and it gets better then worse. Kinda new to rebuilding a mechanical clutch. Never had many problems

Mine had two friction discs and two triangle springs, it's a late production 129. Seems like the manual says you can use two friction discs on HD applications, mine had two when I bought it, so I put two back in it.
Mine didn't stop the PTO well until I replaced the brake lining on the PTO arm, it also brought the adjustment on the actuating rod back into range.
Once you figger it out you will smack your head, I was trying to make it harder than it really was, works like a regular mechanical clutch, the center button is like a throwout bearing.

See my 108 was set up fir heavy duty and the motor i put in came out of 129 that was also heavy duty. So it has dual spriings and disks i just put 1 disk in

The only thing adding two frictions would do is add surface area to the "teeth" on the friction disk that rides in the basket. (Less likely to wear the edge of the "teeth" off.) It does nothing for holding power. There is no reason that with one disk that you should not have been able to adjust the PTO.

I used the gauge to set mine 3 times and it was too tight each time. I ended up assembling the clutch, tightening the 3 screws until I could no longer slip the clutch by hand, then went one round tighter on each screw. This was on advice of a good member here, and it worked like a charm first try. Tilled my whole garden a week ago today and it worked great.
