DISASSEMBLE





1. Remove drive and driven rotors:
a. Remove the cover plate screws.

NOTE: An impact driver and T-30 TORX are required to break the oil pump screws loose.

CAUTION: The oil pump cover screws are coated with a sealant to prevent oil leakage. New screws must be installed if they are removed.





b. Mark the drive rotor and driven rotor with a felt pen. Remove the drive rotor and driven rotor.





2. Remove relief valve.

CAUTION: Whenever the oil pressure regulator valve is removed, it must be replaced. The puller jaws will damage the valve sealing seat upon removal.
