5.2 MOTOR INSPECTION AND
CLEANING
Inspect and clean all parts as follows:
A CLEANING
Clean all parts with a degreasing
solvent. Blow dry with compressed
air and wipe clean. Use only lint-free
cloths.
B GEAR HOUSING
The chamber bores and bottoms
around the shaft bushings should be
polished and not rough or grooved. If
the bushing bores are yellow-bronze,
replace them and investigate the
cause of wear.
 Theflatsurfacesaroundthechamber
andboltholesshouldbeflatandfree
of nicks or burrs that could cause
misalignment or leaks.
C BUSHINGS
The inside of the bushings should
be gray with some bronze showing
through.Ifsignificantyellow-bronze
shows, replace the bushings.
5. MOTOR ASSEMBLY

814PRO SERVICE MANUAL
14
D GEARS
The drive and idler gears should have
straight tips without nicks, square
tooth ends and a smooth even polish
on the teeth and end faces. Check
for cracks between the drive gear
keyway and gear tooth root. Replace
the gear if cracks are present.
E VALVE HANDLE MOTOR SURFACE
The surface near the gears should
show two interconnecting polished
circles without a step. The bottom of
the o-ring groove should be smooth
asshouldtherestoftheflatsurface.
The bore for the shaft seal should be
smooth or oil leakage may occur.
F GEAR HOUSING
The gear housing should be clean
and free of scratches.

G SHAFTS
The shaft diameter at the bearing
and seal locations must be smooth.
Grooves, roughness or a reduced
diameterindicatefluidcontamination
or damaged bushings. Grit particles
may have been imbedded in the
bushings grinding into the hardened
shaft. If abnormal shaft wear as
above occurs (more than normal
polishing), replace both the shaft and
associated bushings.
Also check the hydraulic system for
excesscontaminationinthefluid
andforfiltercondition.Operating
conditions may require changing from
a25-micronfiltertoanoversized
10-micronfilter.
See power pack manual for
instructions.

B To replace the bearing (80) onto the
motor shaft (50), support the bearing
inner race and press the motor shaft
through the bearing inner race.
