Driveshaft Needle Bearing

REASSEMBLY/INSTALLATION
If driveshaft needle bearing failure has occurred, and original bearing race has
turned in the gear housing, gear housing must be replaced. Loose fitting needle
bearing will move out of position and cause repeated failures.
NOTE: Driveshaft needle bearing must be installed prior to installation of reverse gear.
1. Apply a thin coat of Quicksilver 2-4-C w/Teflon Lubricant to driveshaft needle bearing
bore in gear housing.
2. By way of propeller shaft cavity, place needle bearing in driveshaft bore with num-
bered side of bearing facing up driveshaft bore.
3. Install and seat needle bearing with the following tools: Puller Rod* (91-31229), Nut*
(91-24156), Pilot* (91-36571), Plate* (91-29310), and Mandrel* (91-92788). Pull
bearing up into bore until it bottoms on gear housing shoulder. (DO NOT use exces-
sive force.)
