3. Remove the bearing plate bearing using the FMC P502677 bearing removal and installation tool
as follows (see Figure 24):
a. Place the bearing plate on its side on a flat surface that will not scratch or damage the
part. (The worn bearing will be pressed out towards the cam side of the bearing plate.)
b. Insert the pilot plug into the worn bearing so the shoulder on the pilot plug stops against
the bearing.
c. Insert the tension rod through the pilot plug so that the nut of the tension rod is against
the shoulder end of the pilot plug.
d. Place the "adapter can" over the tension rod on the cam side of the bearing plate; slide
the adapter can down the tension rod until it rests on the bearing plate.
e. Screw the speedball handle onto the tension rod until it contacts the adapter can.
f. Continue to rotate the speedball handle clockwise until the worn bearing is pulled from
the bearing plate.

4. Install the new body bearing using the FMC P502677 bearing removal and installation tool as
follows (see Figure 25):
CAUTION
Do not use silicone grease on the inside diameter of the bearing or on the cam
outside diameter. The grease will cause rapid failure of the pressed-in body
bearing.
a. Visually inspect the bearing housing bore for any defects and wipe clean of debris.
NOTE
Before installation, submerge the new bearing in clean, fresh water. Water is the
only lubricant that can be used.
b. Install the reaction plate on the tension rod until it contacts the nut of the tension rod.
c. Insert the pilot plug into the new bearing. The shoulder on the pilot plug needs to stop
against the bearing.
d. Insert the tension rod reaction plate assembly at the opposite end of the new bearing,
through the new bearing and the hole in the pilot plug. Take care not to damage the new
bearing while the tension rod is inserted.
