Remove pump from side of engine by first unbolting oil pump cover. Outer rotor will drop out when cover is removed. Do not allow rotor to be
damaged by dropping it. Oil pump can now be unbolted and disassembled for inspection. Press off drive gear, supporting gear to keep load off
aluminum body. Inner rotor and shaft can now be removed. Remove oil pressure relief valve plug and lift out spring and plunger. Clean all parts
thoroughly. If mating surface of oil pump cover is scratched or grooved, replace pump assembly.
