Pump Disassembly - Toro Reelmaster 216 Service Manual

Pump Disassembly (Fig. 35, 36, 37, 38)
The following procedures are for major repair of the
variable displacement pump. These instructions begin
with the removal of the end cap. Remove the charge
pump, seals, check valves and relief valves before
doing major disassembly (See procedures on previous
pages of this section).

1. When cap screws (Item 46) are loosened, internal
spring loading will cause end cap (Item 45) to separate
slightly. Loosen screws evenly to prevent distortion of
parts. If separation does not occur as screws are loos-
ened, tap end cap with soft hammer until parts separate.
IMPORTANT: Most parts have critical, high toler-
ance surfaces. Use caution to prevent damage to
these surfaces during assembly. Protect exposed
surfaces, opens and ports from damage and foreign
material.

2. Remove end cap (Item 45), however, make sure valve
plate (Item 40) does not fall and become damaged. If
valve plate tends to lift off with end cap, hold it in place
on end cap and remove both parts together. If valve
plate remains on cylinder block, remove it at this time.
3. The end cap is an assembly consisting of a needle
bearing which is a press fit in the end cap and the valve
plate locating pin (Item 41). Inspect bearing (Item 42)
and remove if replacement is required.
