Engine Oil Pump - Install
(Engines Without a Balancer)
Installation Procedure
Note: This procedure is for the installation of the
engine oil pump on engines that are not equipped
with a balancer. Refer to this Disassembly and
Assembly Manual, "Balancer Group - Install" for
information on the installation of the engine oil pump
on engines that are equipped with a balancer.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
NOTICE
If any of the parts on the engine oil pump are worn or
damaged, the entire pump must be replaced.
1. Clean all of the internal components of the oil
pump if the front cover of the oil pump was
previously removed in order to inspect the internal
components. Check the internal components for
wear and for other damage. Check the clearance
between the outer rotor of the oil pump and the
oil pump body. Check the clearance between the
outer rotor and the inner rotor. Check the end
play movement of the rotor. Refer to the Systems
Operation/Testing and Adjusting Manual, "Engine
Oil Pump - Inspect". Replace the engine oil pump
if any of the components are worn or damaged.
2. Lubricate the inner rotor and the outer rotor of the
engine oil pump with clean engine lubricating oil.
Install the front cover of the engine oil pump onto
the body of the oil pump. Install the setscrews and
tighten the setscrews in order to secure the front
