Bearing Carrier And Propeller Shaft Installation - Mercury 40 Service Manual

Bearing Carrier and Propeller Shaft
Installation
1. Insert propeller shaft assembly into bearing
carrier.
2. Before installing bearing carrier assembly into
gear housing, obtain locally a 6 in. (152.4mm)
long by 1-1/4 in. – 1-1/2 in. (31.7mm – 38.1mm)
diameter piece of PVC pipe. Install the PVC pipe
over the prop shaft and secure the pipe against
the bearing carrier assembly with the propeller
nut and tab washer. This will allow the reverse
gear to apply pressure to the reverse gear thrust
bearing to prevent the thrust bearing from being
inadvertently dislodged as the bearing carrier as-
sembly is installed in the gear housing.
