The installation hardware kit includes two (2) O-rings for use on the lower distributor housing. These O-rings must not be installed on the distributor unless the engine block has been specifically machined for their use. Please note that most engines were not machine for the use of the O-rings. Installing a distributor with these O-rings in engines that were not machined for their use will damage the O-rings. Debris from the damage O-rings will end up in the crank case and could lodge in oil galleys resulting in sever engine damage.; A coil with 0.70 Ohms primary resistance or less MUST be used with this MAX-FIRE Ready to Run distributor. For best performance, use a coil with 0.50 Ohms primary resistance or less.; Install a new gasket and lube the gear with the supplied lube, then install the new distributor with the rotor and advance can pointing in the same direction as on the old distributor.; If the distributor will not go all the way down, the pump shaft may have turned while removing the old distributor. Pull out the new distributor. With a long screwdriver, turn the oil pump shaft then reinstall the new distributor making sure the rotor and vacuum can are pointed in the same direction as on the old distributor. When the distributor is properly seated, the trigger wheel will be in line with the magnetic pickup.
