The clutch started smoking and slipping on my model 70 last winter while I was pushing snow. I replaced the disks about a hundred hours ago and was suprised that they were slipping already. When I disassembled the clutch all the replaced disks looked to be in pretty good condition, yet there were pieces of clutch material inside the pulley.When I finally checked the owners manual I discovered that I had neglected to replace the pad behind the drive disk. Do you guys think that this could be the problem? Since replacing the disks the clutch does not fully disengage when the lever is pulled all the way back. When the lever is just pulled back enough to bring it out of the fully engaged position, it seems to function well. But when the lever is pulled back hard, as in an emergency stop to avoid running over a fencepost, the tractor keeps on going. I only throw this in because it has bothered me for some time and I thought it might be a clue. Anyway, I can't remove the drive disk from the crankshaft. I was unable to find a puller large enough to accomodate the 1/2" bolts, so I fashioned one myself from angle iron. After a month of soaking penetrating oil, tapping with a hammer and alternately tightening and loosening the puller, not so much as a budge. Any suggestions as to getting this thing off? Also the book suggests aligning the timing marks on the disk and crankshaft during reassembly. Mine are already off a couple of teeth. Do I replace them that way or follow the instructions? Thanks in advance for your help.
