GEARCASE
CLEANING AND INSPECTION
9
Using Puller Bridge, P/N 432127, and Bearing
Puller, P/N 432130, remove the larger propeller
shaft bearing located in the front of the bearing
housing. Discard the bearing.
CLEANING AND
INSPECTION
Discard all seals, O-rings, gaskets, and clutch dog
spring.
Clean all gearcase components in solvent and dry
with compressed air. After cleaning, coat all inter-
nal components with HPF XR gearcase lubricant
to prevent rusting.
Perform the following inspections:
• Gearcase housing — all gasket surfaces must
be free of gasket material. All threaded holes
must be free of corrosion and sealer.
• Gearcase anode — if anode has been reduced
to two-thirds of its original size, it must be
replaced. Refer to Anode Testing Procedure –
Continuity on p. 52.
• Driveshaft — check splines for chips, wear,
and cracks. Bearing and gear surfaces must not
show signs of metal transfer, corrosion, or dis-
coloration. Severe spline wear might indicate an
exhaust housing or gearcase has been dis-
torted by impact damage.
• Water intake screen — must be clear. If
screen can't be cleaned, it must be replaced.
• All internal components — must be visually
inspected for signs of wear, distortion, chipping,
metal transfer, pitting, galling, and discoloration
due to improper lubrication.
• Water pump — check impeller for wear, crum-
bling, and hub bonding. Check impeller cup and
plate for scoring and distortion.
