Remove the two mounting capscrews and the lubricating
oil filter head.
Disassemble
CAUTION
To prevent the possibility of high filter restriction after
installation and causing filter damage, be sure to
mark the lubricating lines, oil filter head inlet and
outlet ports. Failure to do so can cause the center
filter media to break up and be pumped through the
engine.
Label the filter head connectors to identify the lubricating
oil connections and fitting orientation.
Remove the fittings from the lubricating oil filter head.
Inspect for Reuse
Inspect the lubricating oil filter head sealing surfaces and
bypass, if equipped.
Assemble
Replace the compression o-ring seals and o-rings on all
face sealing connections.
Lubricate the o-rings with clean engine oil.
Install the inlet and outlet connections into the filter heads.
Be sure the lubricating oil connections are orientated
correctly and they are installed to their proper depth.
Do not torque or tighten the fitting locknuts at this time.
