I can't seem to get the flywheel off my 35hp motor, I read how to do it and got a puller and some grade 8 bolts and that seem to fit the flywheel just fine. When I put pressure on the puller nothing seems to happen, I firts used a braker bar than whent to a inpact gun but don't like that because I don't want to brake it; there is a lot of pressure on the puller and seems like it should come off. Should it take a lot of pressue (say 250ft/lbs)? Is there something like a c-clip in there or is it just the nut and lock washer that hold it to the crank? Can and should I use heat? Any help?
