REASSEMBLY
When the part concerned has been removed, clean the
cover dividing plane and remove any gasket fragments
and residual sealing compound. Inspect and clean all dis-
assembled parts, as well as the transmission case, in kero-
sene or the like. Make sure that such items as poppet balls,
needles from broken bearing, etc., are not left in the case.
Then commence reassembly at the appropriate 90"“ in
the following description.
Pinion shaft with bearings and gears
1. Using an arbor press and tool 78 41 067 drive the
roller bearing and pinion shaft 4th gear in until the
inner bearing race is flush with the pinion gear.
Mount the spacers and speedometer drive on the
pinion shaft.
On earlier gear units make sure that the matching
number faces the same way as on the 4th speed
gear. On later gear units there are no matching
number. The 4th speed gear is marked with a X on
that side, which will face from the gear end of the
pinion shaft.
2. Next, pass the pinion shaft through the end of and
into the transmission case from the differential side,
and then locate the pinion shaft 3rd gear on the
shaft inside the case. Make sure that the Woodruff
key for the 3rd gear has been fitted to the pinion
shaft. In some older units, the pinion shaft 4th
gear is also held by a Woodruff key instead of
being press fitted.
3. Turn the shaft to align the Woodruff key in rela-
tion to the groove in the 3rd gear.
4. Insert the guiding arbor 78 41 224, in the rear bear-
ing seat so that the pinion shaft passes into it.
5. Secure the arbor with the rear press screw so that
its flange is flush against the transmission case end.

Drive the pinion shaft finally home With the front
6. press screw, checking that the key Engages in the
pinion shaft 3rd gear.
7 Back off the rear press screws and remoVe the arbOr
from the bearing seat.
8 Place an 0.14 in. (3.6 mm) spaceron the shaft and,
NOTE! If the rear pinion bearing IS eqUIpped With Split
inner ring, the spacer washer has to be placed next to the
bearing. The washer diameter will be 1.4 in. (36 mm).
NOTE
If no part of the pinion shaft assembly has been re-
newed, the previously used spacer and shims may be
refitted.

Using the press screw and arbor 78 41 224, presS
the rear ball bearing, complete with retaining ring,
into the transmission case end. Use the press screw
at the front end of the pinion shaft as a suppert
during this operation.

In case of a split bearing, fit the inner ring first and
then the principal part of the bearing on the shaft-
Then press the bearing in, as described above.
Fit a new tabbed washer and lock nut (NOTE! Left
hand threaded) on the pinion shaft. Note that the
nut should not be tightened until the primarv- and
counter shaft are installed. See position 26.
