Hello, I have a 99 CR-V and i was noticing how much free space is leftover in the cranshaft keyway. Normally it uses 2 woodruf keys , one for timing belt pulley and one for the cranksaft pulley. Has anyone had success using one of the longer, single keys from Honda. If so what part #? or can a 3rd key be placed in there , ground to fit? 3 normal size keys are little too long, 3rd one would need to be ground a bit. Just wondering since its an easy what to add extra protection over pulleys sheering them off. Usually the damage in the keyway is due to a loose crankshaft pulley bolt. Just thought I'd beef it up a bit in there.
