It looks very clean in there, but I can not get the solid driver disk off the splined shaft. I even managed to break out one of the puller bolt holes in the driver disk....bummer. Any ideas? This project all came about because the clutch would not release after I ran it the last time (three days ago)while loading on a trailer. I can roll the belt pulley and hear parts of the mechanism rattling around in the back of the pulley. Thanks Chuck [Reply]   [No Email]

I guess i will just need to get longer bolts and try again. Any ideas where to get a new driver disk if this one is not salvageable? Thanks Chuck [Reply]  [No Email]

Those things can stick on there good sometimes. I don't think I've seen any reproductions, your only choice would be salvage yards. I think I've seen one on Ebay too, though it was a bit spendy. All the 80, 820, 830s use them, maybe the R, but not sure. Brandon [Reply]  [No Email]

The service manual says to make a simple plate to slide two bolts through, tightening into the driver, then to push everything with a center bolt pushing on the crank bolt to pull off the driver...It works really well. If one bolt hole is broke, you could try putting some pressure on it with the remaining bolt, and some not too hard smacking on the center bolt, or a little bit of head on the driver, it might pop loose, though a bit iffy as it's pulling crooked that way. Go for a puller if you can find one. I'd be sure you're using the right size bolt that threads into the driver. I've grabbed the next size down once or twice and it wouldn't hold...until I looked at what I was doing! I'd thread it in as far as you can too, as there is a lot of force and you want it spread as much as possible. It is different than Frank's 70. Both have their quirks. My 80 has a small chunk out of a driver thread, though it's still useable. On my 70 I ended up breaking the driver. It probably hadn't been off in decades. Oh, make sure you have the driver and crank marked for position. It DOES matter on the 80, they counterbalance each other. Brandon [Reply]  [No Email]

They are not meant to just hold a pulley arm. Lots more meat if they are all the way through and seated. [Reply]  [No Email]
