1. Remove the new crankshaft rear seal and wear ring assembly and plastic step-up tool from the packing. Separate the plastic step-up tool (if installed on the crankcase rear seal) from the crankcase rear seal and wear ring assembly.
NOTE: The crankshaft rear seal and wear ring are one-piece and need to be installed as an assembly. Do not separate the wear ring from the crankshaft rear seal or damage to the seal may occur.

NOTE: Lubricate the outer diameter of the rubber seal with a solution of dish soap and water (approximately 50/50 mix) prior to assembly. Do not use any other type of lubricant.
