WARNING  To reduce the possibility of personal injury, avoid direct contact of hot oil with your skin.

WARNING  Some state and federal agencies have determined that used engine oil can be carcinogenic and cause reproductive toxicity. Avoid inhalation of vapors, ingestion, and prolonged contact with used engine oil. If not reused, dispose of in accordance with local environmental regulations.

WARNING  Batteries can emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To reduce the possibility of arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.

CAUTION  Use caution when draining oil or replacing filters that oil is not spilled or drained into the bilge area. The oil and oil filters must be discarded in accordance with local environmental regulations.

• Disconnect the battery. Refer to Procedure
  013-009.

Loosen, but do
not remove, the inlet and outlet lubricating oil filter head face seal connection locknuts.

Remove the four mounting capscrews and the lubricating oil filter head.

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 the lubricating oil filter head sealing surfaces and bypass, if equipped.

Replace the compression o-ring seals and o-rings on all face sealing connections.

Lubricate o-ring 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.

CAUTION  To prevent the possibility of high filter restriction after installation and causing filter damage, be sure the lubricating lines, oil filter head inlet and outlet ports are orientated correctly to the bracket prior to installation. Failure to do so can cause the center filter media to break up and be pumped through the engine.

Install the filter head assembly to the bracket and tighten the capscrews.

Tighten the lubricating oil filter inlet and outlet connection locking nuts.

WARNING  Batteries can emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To reduce the possibility of arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
