I need some help. I'm replacing the top gear on my MB 35, i need to know how to take the gear off. I have thje clutch removed, but now having trouble removing the gear.

Its a pain to remove the first time, took me a while to figure it out. Take out the two allen screws and screw one into the hole opposite the split in the fitting. Once it is as far as itll go, get a wood block and tap the pulley back to the engine block, it should come off the fitting with some force. Poke a flat head into the split on the fitting and it should wiggle off pretty easily and presto.
