remember on the JP set its not uncommon to have to hone the crank gear to match your crank snout! DO NOT use heat to install it, should be a snug fit but go on with light taps from a dead blow hammer. You will need a mic (not dial calipers) and measure the snout, give that spec to the machine shop and they will hone the gear, that said mine was dead on but i have seen them have to be cut off...
