Step 1
Remove the pump from the vehicle and clean pump exterior.
Place the pump on its side on a clean work surface. Scribe or
draw a line across the pump motor housing, gerotor housing,
port plate and fuel chamber so that you can reassemble the
pump correctly (See Figure 1).
Step 2
Remove the fuel chamber screws from the bottom of the pump,
then remove the fuel chamber and port plate from the pump.
NOTE: Do not drop the gerotor from the gerotor housing
cavity (See Figure 2).
Step 3
Place your hand beneath the gerotor and hold the pump in an
upright position. The gerotor should slide out of the gerotor
housing and into your hand (See Figure 3).
Step 4
Remove the motor screws from the top of the pump. Remove
the motor from the gerotor housing. (See Figure 4). Push the
armature into the motor housing about 1-1/4" and slide the
grommet out of its slot. Pull end cap off the commutator
(See Figure 5).
Step 5
From the center of the end cap, push the brushes back into the
brush holders (See Figure 6), untill the brush spring fingers are
resting against the sides of the brushes (See Figure 7). Pull
brushes out of the brush holders. The brush spring fingers will
“snap” back into the brush holders. Disconnect the brush leads
from the end cap.
Step 6
Connect the new brush leads to the end cap. Using a small
screwdriver, paper clip, or similar device, pull the brush spring
fingers back and insert the new brushes into the brush holders.
Release the brush springs. From the center of the end cap, push
the new brushes back into the brush holders (See Figure 6) until
brush spring fingers are resting against the sides of the brushes
(See Figure 7).
Step 7
Slide the grommet into its slot. Push the armature into the
motor housing about 1" and hold it there. Place the end cap
on the commutator. Push the brushes into the brush holders.
The brush spring fingers will “snap” into place. Hold the end
cap firmly on the commutator. Slowly lower the end cap and
commutator into the motor housing until the end cap is fully
seated (See Figure 5).
Step 8
Place the motor housing on the gerotor housing. Make sure the
line across the pump (as described in STEP 1 and Figure 1)
align. Install the motor screws and torque to 24 in-lbs.
Step 9
Clean the gerotor cavity. Install the gerotor in the gerotor
housing. Inspect the o-ring and gasket and replace if necessary.
Install the port plate, gasket and fuel chamber with screws.
Make sure the line across the pump (as described in STEP 1
and Figure 1) align. Install the fuel chamber screws and torque
to 24 in-lbs.
