OK cool. One less thing to have to buy :)

While I have things apart is it worth putting a kevlar disc in? I'm going to put in a blue spring rather then stock. What I'm worried about is this clutch engaging to fast and not giving me the chance to ease into gear. The tractor is basically only used to pull loads around the property and plow snow. I realize my driveway is not a monster but it's pretty wide. With the snow we get up here I'm expecting this tractor is going to have to push some pretty good amounts of snow so I looking to get everything prep'd best I can.

Keep it stock. That's what the teaser spring is for, to ease into full engagement.

More important is the amount of wear on the throw out lever where it meets the bearing {the rounded portions)
Is there a lot? If so, are the surfaces evenly worn? Or lopsided, thin on one side and thick on the other?
This will cause premature T/O bearing failure IMHO.

Is the pivot bolt about worn through? How about the holes it passes through? Are they all hogged out and worn? This will cause lopsided T/O bearing engagement also.

This area, again, IMHO, is an area that calls for greater bearing surface area, room for modification & improvement.

Its not a bad idea to beef up the clutch on a plow tractor, my 108 started to slip pushing the heavy snow we got last year and that was with a brand new clutch and a nos spring.

All other parts are looking pretty good. The leaver has little wear at all on it. The pivot bolt is just fine and so is the hanger for the clutch. The main reason for the rebuild is not because the PO really used the tractor much but that the disc just got brittle and was falling apart and the pressure discs where all rusted. Since I have it apart I just thought I would replace stuff and make some upgrades here and there. I have a new bearing going in and teaser spring. Jeff is making me a new drive shaft and I bought that blue spring. My plates have been refaced and the driver pins look pretty good. Really not much were on the other moving parts. I bought a stock disc but since I'm going to be moving snow and after some reading I just thought I would ask you folks about the kevlar one. It's going to be a lot easier to put the kevlar disc in now then in my driveway in the freezing cold later if I'm wrong :(

108 clutch should have the spacer or you geometry will be off. # 20 If I remember it's 1/2 inch wide

Thank you. Yes I agree and will make sure this spacer is placed back into the clutch. Hoping the next time this gets worked on it's because my daughter's have kids and those little buggers are playing with grandpa's tractor HAHAHA

Pushed plenty of snow with the stock clutch disc. My first disk lasted 30 years. You'll spin the rear wheels with chains on them before the clutch will slip. Unless the Kevlar disc is cheaper, I see no reason to change. YMMV.

Kevlar is cheaper ( at least $10) and the hotter it gets the better it grabs.

Where are you getting your Kevlar discs?
