OIL FILTER MOUNT
GENERAL
See Figure 3-48. Oil is pressure-fed from the oil pump to the
oil ļ¬lter mount (4) via a hose connection (5). Oil travels
through the ļ¬lter mount into the ļ¬lter via outer ļ¬lter holes.
Adequate oil pressure activates the oil pressure signal light
switch (6) in the ļ¬lter mount, which turns off the oil pressure
indicator lamp.
The check ball (2) in the ļ¬lter adapter (1) āopensā at 4-6 psi
(28-41 kN/m
2
) oil pressure. Filtered oil leaves the ļ¬lter, ļ¬ow-
ing past the check ball.
DISASSEMBLY
1. Remove oil ļ¬lter adapter (1) from oil ļ¬lter mount (4).
Remove check ball (2) and spring (3).
2. Remove oil pressure signal light switch (6).
CLEANING/INSPECTION
Thoroughly clean all parts in cleaning solvent. Blow out holes
and passages using compressed air.
ASSEMBLY
NOTE
Use TEFLON PIPE SEALANT or HYLOMAR on all ļ¬ttings
installed to oil ļ¬lter mount.
1. Install oil pressure signal light switch (6). Tighten to 5-
7 ft-lbs (7-9 Nm).
2. Apply LOCTITE THREADLOCKER 242 (blue) to the
threads on that end of the oil ļ¬lter adapter (1) which is
installed into oil ļ¬lter mount (4). Do not apply LOCTITE to
adapter threads on oil ļ¬lter element side.
NOTE
The oil ļ¬lter adapter (1) has identical ends; either end may be
installed into the oil ļ¬lter mount.
3. Place spring (3) and check ball (2) into threaded hole at
center of mount (4). Push adapter (1) against ball to
compress spring. Install threaded end (with LOCTITE)
into threaded hole at center of mount (4). Tighten adapter
to 8-12 ft-lbs (11-16 Nm).
4. Connect pressure switch wire. Tighten nut which secures
wire to 4-10 in-lbs (0.4-1.1 Nm).
5. Pour about 4.0 ounces (0.12 liter) of clean engine oil into
ļ¬lter. Apply a light coat of oil to oil ļ¬lter gasket. Install oil
ļ¬lter onto oil ļ¬lter mount/adapter assembly; tighten ļ¬lter
an additional 1/2-3/4 turn after gasket contacts ļ¬lter
mount surface.
6. Fill oil tank with proper oil. See ENGINE LUBRICATION
SYSTEM, CHANGING ENGINE OIL AND FILTER in
Section 1.
