1. Grease the needle bearing (13) with Universal
Grease and drive the bearing into the yoke by using
tools 884259 and 9991801. Press in both the seal
rings (14) with the help of the same tools.
NOTE: The seal rings should prevent water from
forcing its way in, see Fig. 17. Glue on the bush (12)
with VP 1161351-0 and fit the bush in the yoke with
the flange facing down towards the retaining pawl.
2. Fit the shaft (59) on one of the retaining pawls (47)
and install the spacer washer (49) and the spring hook
(58). Screw one of the nuts (61) onto the shaft. Then
place the thrust rod (50) on the stop shaft (62) and fit
the journalling (48) in the retaining pawl half. After this
place the thrust rod (50) and the stop shaft (62) in the
retaining pawl half. Then fit the other retaining pawl
(47) and the spring hook (60) with spacer washer (49)
on the shaft (59) and journalling (48). Screw tight the
other nut (61).
NOTE: The nuts (61) are tightened fully and then
slackened about 1/8 of a turn so that the spring hooks
are movable without being loose. Now fit the lock
clamp (52) and the shaft pins (53) with spring (63) and
washer (56) in the journalling (48). Place the spring
shaft (55) in position with the help of the springs (64)
and fit the spring (54) between the journalling (48) and
the stop shaft (62). Paint the retaining pawl with a thin
coating of original VP touch-up paint.
3. Fit the retaining pawl in the yoke and screw tight
the guide plugs (18).

4. Fit the yoke with the retaining pawl on the interme-
diate housing.
NOTE: Do not forget the wear washer (26) between
the lower attachment of the yoke and the intermediate
housing, also the two plastic washers (66) on each
side of the journalling (48). Observe due care when
fitting the guide spindle not to damage the seal ring.
5. Fit the hose attachment and packing on the yoke.
Coat the surfaces with VP sealing compound
1141570-0.
6. Fit the shift yoke and push in the shaft (4) and lock
with a split pin.
NOTE: A washer (5) should be fitted on each side of
the split pin.
Part V Reconditioning the lower gear
A. Removing
1. Lift up the oil strainer out of the oil channel. (Only
the later type gear has an oil strainer).
2. Remove the two screws (8) retaining the propeller
bearing housing (3). Remove the propeller shaft (14)
and the propeller bearing housing with the help of tool
884161, see Fig. 18. If no such tool is available, then
removal can be carried out by holding the propeller
shaft and striking on the gear housing with a rubber
mallet until the propeller shaft together with the pro-
peller bearing housing loosens from the gear housing.
3. Turn the lower gear housing upside down in tool
884264. Then bend up the lock washer (23) on the nut
(22), which retains the gear on the vertical drive shaft
and unscrew the nut.
4. Strike up the lock washer (20) and unscrew the
round nut (21). Remove the lock washer and spacer
ring (19).
5. Loosen the gear with the help of tools 884267 and
