3.9.5) Propeller shaft removal
See Figs. 72-28 and 72-29.
Place gearbox housing on a suitable surface and press out the propeller
shaft with a hand press. Alternatively, the extractor (1), part no.
877615, can be used to press out the propeller shaft.
Fit the extractor onto the gearbox housing (3) with 6 x M6 screws (2)
and place press-out insert (4), part no. 877605 (for engine configura-
tion 2), or press-out insert (5), part no. 877600, (for configurations 3
and 4) on the end (6) of the propeller shaft (7).
Insert pull-in spindle (8) into the support (9) of the extractor (1) and
screw hex. nut (10) M24x1.5 onto the spindle (8) from the inside. Keep
nut in position with fork wrench. By turning the spindle clockwise, the
propeller shaft is pressed out of the gearbox housing.
■ CAUTION : The protection piece must be used without fail, as other-
wise the machined inner diameter of propeller shaft would
be damaged. If the propeller shaft is removed, the ball
bearing (11) must be replaced!
To remove the ball bearing (11), unscrew the 4 hex. screws (12) M7x16
with the washers (13) from the gearbox housing (3).
■ CAUTION : During this procedure, the shaft seal (14) will be
damaged and must be replaced.
Heat the gearbox housing to 80 to 100
°
C (176 to 212 °F) and knock the
ball bearing (11) out, together with the oil seal (14) and the radius ring
(15), using a suitable punch and from the outside towards the inside.
