Lubrication, Electric
Vehicle
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
rear tires.
2. Using a clean rag, wipe all dirt from both power
steering motor grease fittings. See
Fig. 2 for the
location of the grease fittings.
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.
3. 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.
4. Wipe off any excess grease from the fittings.
5. Remove the chocks from the tires.
