GENERAL
See
Figure 3-48.
Oil is pressure-fed from the oil pump to the
oil filter mount (4) via a hose connection (5). Oil travels
through the filter mount into the filter via outer filter holes.
Adequate oil pressure activates the oil pressure signal light
switch (6) in the filter mount, which turns off the oil pressure
indicator lamp.
The check ball (2) in the filter adapter (1) "opens" at 4-6 psi
2
(28-41 kN/m
) oil pressure. Filtered oil leaves the filter, flow-
ing past the check ball.
DISASSEMBLY
1.
Remove oil filter adapter (1) from oil filter mount (4).
