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 endcap covering
the servo piston and hold the endcap level while remov-
ing.
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 identifi-
cation, 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 bear-
ing 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 jour-
nal as the bearing may become trapped on the shaft
and damaged.
