Repair instructions
9. Install special tool 884830 onto the splines end and
turn the gear in the set direction of rotation, clockwise
for left handed propeller. At the same time brake the
movement on the propeller shaft, as forcefully as pos-
sible.
10. Check that the contact pattern on the teeth surfac-
es of the drive side coincide with that of the picture
“A”, which is correct. The contact pattern should be
positioned in the middle of the tooth but displaced to-
wards the small end.
11. Should the contact pattern correspond to that of
picture “B”, reduce the shim thickness for the vertical
shaft and the propeller shaft.
12. Should the contact pattern correspond to that of
picture “C”, increase the shim thickness for the verti-
cal shaft and the propeller shaft.
NOTE! If the pinion is moved the gear wheel must be
moved correspondingly in order not to alter the gear
backlash.
