NOTICE
Do not over-lubricate the power steering motor.
Over-lubrication of a motor can seriously damage
it by forcing grease into motor windings, as well
as the centrifugal switch, causing it to malfunc-
tion.
IMPORTANT: Due to the high operating tem-
peratures of the motor, use Darmex RPL-707
grease for motor lubrication.
7. Using a hand-type grease gun with Darmex RPL-
707 grease, insert the adaptor over the grease
fittings and pump the handle two or three times
to fill the grease cavity.
Listen closely as the grease is pumped in. When
you hear a sound like air being released, the
grease cavity is full.
8. Wipe off any excess grease from the fittings.
9. Install the compressor assembly to the front box
and refrigerant system.
10. Charge the refrigerant system per Section
83.03, Subject 110 of the Walk-In Van Chassis
Workshop Manual .
11. Close the hood.
