DESCRIPTION:
The oil pickup assembly consists of a cylindrical plastic tube
with a screen. Two o-ring seals are installed in grooves at one
end of the cylinder. The pickup slides into a bore of the oil
filter pad in the crankcase cover and extends into the inte-
rior of the crankcase (see Figure 9-). Once installed in the
crankcase cover bore, the pickup is retained by either of the
following methods:
. If the engine is supplied with an optional oil filter, the
pickup is prevented from coming out of the bore by the
oil filter adapter.
2. If the engine is not equipped with an optional oil filter,
pickup is retained by an oil filter pad cover.

INSPECTION:
Remove the o-ring seals, then clean the pickup in solvent.
Inspect the plastic body for cracks or other damage. Check the
pickup screen for damage or clogging.
Make sure the hollow
tube is free of obstructions.
Install the two o-ring seals prior to reassembly. Replace the
oil pickup assembly if it is damaged, if the screen is torn or
plugged or if the tube is plugged. Replace damaged o-rings.
