LUBRICATION SYSTEM
Testing Oil Pump — An oil pressure tap is located
above oil pump cover plate (Fig. 13). Oil pressure
should be 12—18 psi above suction pressure.
OIL FILTER SCREEN is accessible thru bottom
cover plate. Remove and inspect strainer for holes
and dirt. Clean it with solvent and replace.
Oil Pump and Bearing Head — The oil pump
assembly is contained in the pump end bearing
head aluminum casting. (The pump end main
bearing is a machined part of this casting — no
insert bearing.)
REMOVE bearing head from crankcase and dis­
assemble oil pump. Drive segment cap screws must
be removed before bearing head can be removed
(Fig. 13). Remove pump vane assemblies from
both sides of bearing head. Push the pump rotor
out of the bearing head by pushing against the
bearing side of the rotor. Check all parts (Fig. 14)
for wear and damage.
REPLACE
1. Install the rotor retaining ring in the ring groove
of the pump rotor with chamfered edge toward
compressor. Compress retaining ring, and insert
pump rotor into bearing head.
