I first replaced the timing belt and damaged the piston ring (rubber). I had to go on internet several times to complete repair. There are (weird)long bolts through the covering. There is a reverse thread bolt on the fan. There is a torx bolt holding the piston ring cover on. Had to heat the piston ring crank shaft with a torch to get the torx bolt out. Couldn\'t get it out with an impact driver. The new piston ring is hard to get back in place. You need to premold the new ring and slide the piston in at an angle in to the cylinder or you will never get it back in. There are two small plates of steel in the compressor head that keep falling out and getting out of position. Getting the timing belt on is difficult too. Bostitch Model CAP2000P-OF
