Cub Cadet P Series - Manual (Page 105)

100 PR Series
Refer to Figure 11.
Disassembly
1. Using any combination of two, 9/16” wrenches
or 9/16” socket and ratchet drive, loosen the
end cap bolts (58) evenly.
2. Keeping the end cap (25) held in place, remove
the four end cap bolts (58).
3. Slowly remove the end cap (25).
4. Remove the valve plate (29).
NOTE: This step is only applicable on PR series
pumps built prior to 0216Pxxxxx.
5. Remove housing alignment pins (26).
6. Remove housing gasket (28).
Inspection
1. Inspect the end cap (25) body for damage,
nicks or unusual wear patterns. Replace if
necessary.
2. Inspect the running surface (side that contacts
the cylinder block) of the valve plate (29) and/
or end cap (25). The running surface may
show evidence of minor abrasive rings, this is
normal.
NOTE: Grooving in the valve plate and/or end
cap, made evident when the surface is checked
by dragging a fingernail across it, would be
cause for replacement of the valve plate.
3. Inspect and replace alignment pins (26) if bent
or distorted.
4. Replace the housing O-ring (28) with a new
O-ring before reassembly.
Assembly
1. Install O-ring (28) into the O-ring seat of housing
(15).
2. Install alignment pins (26) into housing (15).
3. Lubricate the valve plate prior to installation.
Install valve plate (29) so the bronze side of the
valve plate is facing down toward the cylinder
block.
NOTE: This step is only applicable on PR
series pumps built prior to 0216Pxxxxx.
4. On pumps built without a valve plate, lubricate
the end cap (25) prior to installation.
5. Install end cap (25). Before installing the four
end cap bolts (58), push down on the end cap
(25) verifying alignment and insuring that the
cylinder block pistons spring back and forth.
Install and torque end cap bolts (58). Reference
Table 2, page 92 (torque values).
