7. Install the high pressure seal into the groove in the
housing.
8. Install the metal backup shim against the high pres-
sure seal in the groove in the housing bore by
squeezing the shim between the thumb and forefin-
ger to bow shim (bow in the shim should be in the
shape of a hill and not a valley for easier installation).
9. While maintaining the bow in the shim, start the shim
into the groove and use a small screwdriver to push
the shim into the groove. Install the wire ring into the
groove making sure the ends are butted.
Shaft Timing Procedure
FOR PROPER OPERATION, THE MOTOR DEPENDS ON THE COR-
RECT ORIENTATION OF PARTS AS WELL AS THE CORRECT
INTERNAL TIMING.
1. Turn shaft over so the output end of the shaft faces
down.
2. Install the cooling plug into the shaft making sure
the large OD end of the cooling plug faces up.
3. Lower the drive link into the shaft making sure that
the timing mark end of the drive link faces up and
the timing mark on the end of the drive link is
aligned with one of the through holes in the shaft.
4. When the splines contact each other, slowly rotate
the drive link counterclockwise until the drive link
splines engage with those on the shaft.
5. Turn the housing over so the pilot of the housing
faces down and secure the housing in a vise.
6. Without disturbing the seal carrier assembly or drive
link, carefully lower the shaft assembly into the
housing.
7. To seat the seal carrier against the wire ring, gently
tap the drive link down until the end of the shaft is
nearly flush with the rear surface of the housing.
8. Place a body seal in the groove in the rear surface of
the housing.
9. Using alignment marks as a guide, place the wear
plate on the housing making sure the notch in the
wear plate is aligned with the port side of the hous-
ing as shown in Figure 3-11., Notch Alignment.
10. Place a body seal in the grove in the face of the
rotor.
