Install Oil Filter Housing Assembly

Reassemble oil ﬁ lter housing if disassembled previously.

Reassembly

1. Install small spring onto rubber valve, and insert

small end through corresponding hole in cup until

properly seated.

2. Install larger spring into ﬁ lter housing.
3. Insert oil ﬁ lter cup, aligning cutout with

corresponding section in housing.

4. Install nipple in housing and torque to 17.8 N·m

(158 in. lb.).

Installation

1. Make sure all sealing surfaces are clean and all

dowel pins are in position. Install or check new

O-rings are around all oil ﬁ lter adapter dowel pins.

2. Install oil ﬁ lter housing assembly and secure with M8

screw. Make sure housing is ﬂ at on crankcase and

all O-rings remain in position. Torque screw to

23.7 N·m (210 in. lb.)

3. Oil ﬁ lter may be installed now or upon completion of

engine assembly.
