p.
The tapered bearing (35) must now be removed from the shaft. A bearing puller should be used that will pull
against the inner race of the bearing. A spacer is required to protect the slot in the end of the pump shaft from
the puller screw. Protect the face of the cylinder block (34) during this operation.
q.
After removal of the bearing (35), slip the spacer (36) out of the bore in the cylinder block (34). Place the pump
horizontally in preparation for removal of the cylinder block assembly (37).
r.
Slide the cylinder block assembly (37) off the shaft while holding the external end of the shaft. If the cylinder
block assembly does not remain together during removal, it can be easily reassembled at a later time.
s.
Set the pump on the servo housings (38) and remove the front cover screws (39) and washers (40). Lift off the
front cover (41) and gasket (42).
t.
The race (43) for the tapered shaft bearing (44) is a press fit in the front cover (41).
u.
Lift the shaft (45) and bearing (44) out of the center hole of the swashplate (46).
v.
Remove thrust plate (47) from its counterbore in the face of the swashplate (46). Reach through the center hole
in swashplate and push against exposed edge of thrust plate (47). Do not allow part to fall and become
damaged.
w.
The tapered bearing (44) can be pressed off the shaft (45) if required. Be careful not to damage the seal
diameter of the shaft while removing the bearing.
NOTE
From this point on it is necessary to mark all parts so that neutral (zero swashplate angle) will
be retained when the parts are reassembled. The swashplate is held in neutral by springs
inside the servo housings. These springs are adjusted by turning the servo housings.
x.
First, mark the servo housing (38) for location to the pump housing. This set of marks should line up to show the
rotational position of the servo housing to the pump housing.
y.
Remove the locking retainers (49) using a 12 point, 3/16 socket for the cap screws (48).
NOTE
After removing the retainers (49), scribe a line to mark the height of the servo housing in
relation to the pump housing.
