13. Using an 8 mm internal hex wrench, remove the
endcap screws (22).
14. Remove the endcap (23). Remove O-ring (24) from
the housing or endcap.
When the endcap screws are removed, pressure
from the servo spring will cause the endcap to bind
on the shaft. Press down on the portion of the end-
cap covering the servo piston and hold the endcap
level while removing.
TAKE CARE NOT TO SCRATCH THE SURFACE OF THE VALVE
PLATE.
15. Remove the valve plate (25) and timing pin (26) from
the endcap.
Each displacement has a unique valve plate. For
identification, the last two digits of the valve plate
part number are stamped on its surface.
16. Remove and discard the O-rings (27, 28).
17. Remove the rear shaft bearing (29) from the endcap
with a bearing puller.
The bearing may be difficult to remove with a puller.
Try this as an alternative: Pack the bearing cavity
with heavy grease. After the shaft is removed, insert
it into the bearing cavity and tap lightly with a soft
mallet on the splined end. The grease will force the
bearing out. Use caution not to drive the bearing
past the rear shaft journal as the bearing may
become trapped on the shaft and damaged.
