I recently took my stock blower off and put on a ported unit, I took apart the snout off the stock unit and was checking the coupler, ect. My questions are how much gear oil do i need to put back in it, is it the 4.7oz that eaton says, could i put more? and also do i need to make a gasket for the snout or loctite the bolts? I didnt see a gasket when i took it apart. thanks I trust you guys more than anyone else with my 500.
