Hi not sure if this is the right forum, but just bought a rapidor power hacksaw, is in good shape but needs stripping cleaning and painting. Bought is from a farmer so has not seen any oil in years. I am having trouble getting the drive shaft and pulley off. Removed the nut holding the ecentric cam but its solid and wont come off, tried removing the spring on the clutch but cant move either. Cant get spares for these ang more so stopped as dont want to break anyrhing. How have other folk got these apart?
