Assembly - Toro Reelmaster 6500-D Service Manual

Camplate Inspection:
¯ The finish on the piston shoe surfaces of the camplate
should show no signs of scoring.
¯ Inspect camplate bushing (23) surface for wear and
surface for coating transfer from bushing.
12. To remove servo piston assembly (7) from housing,
start with the four each cap screws and washers (5 & 44)
retaining each cover plate (13 & 9).
13. In removing the cover plate (13) from the servo pis-

Note: Disassembly of servo piston assembly is not re-
quired.
15. Remove retaining ring (2) from the front of housing.
Press the shaft (25), shaft seal (31), and washer (29)
from housing. Remove both retaining rings (3), both
