Removal of roller bearing for - Series 4
See Fig. 72-24.
After the propeller gearbox is removed, the crankcase side propeller
shaft bearing can be replaced if necessary.
For the extracting procedure it is necessary to drill a bore (2) of at least
6.2 mm dia., (1/4") into the center of the oil inlet cover (1).
■ CAUTION : The oil inlet cover is thus rendered useless and must be
replaced before installation!
■ CAUTION : Grease the grooves of the drill slightly to ensure that the
majority of the metal chips adhere to the drill. Remove
metal chips carefully after drilling.
The roller bearing is pulled out together with the oil inlet cover. Remove
the retaining ring (3) with circlip pliers. On the gearbox side, fit puller cap
(4), part no. 876489, and push hex. screw (5) through the cap, roller
bearing (6) and the hole drilled in the oil inlet cover (1). Fit the pullout
plate (7) with the nut (9) and washer (8) on the back end. By turning the
hex. screw clockwise, the roller bearing is pulled out together with the
oil inlet cover. Remove the O-ring (10).
