(F) Assembly:
Oil all sliding parts with gearbox oil when assembling.
Check catch of reverse gear for easy operation.

Remove all sealing caps.

Replace only on grooved ball bearing.
The grooved ball bearing is a C-3 bearing and must be
compensated to zero between casing and bearing support.
Measure depth of casing A, e. g. 13.1 mm (0.5158").

Measure depth B on bearing support ring, e. g. 6.0 mm
(0.2362").

Width of grooved ball bearing C 19.0 mm (0.7480").
Measure width of shim D.

Insert grooved ball bearing into bearing support together
with shim.

Press bearing with support, supporting disy as speedo-
meter drive worm onto output drive shaft.

Screw two guide bolts into support.
The recess in the supporting ring is at the bottom.
Heat top of casing to approx. 80° C (176° F).
Insert output drive layshaft and reverse gear into cas-
ing top.

Fasten support.
Unscrew guide bolts.

Insert gearshift shaft.
Important: Note rollers.
Fit on shift forks; the higher shift fork is for 3rd gear and
4th gear.
Put stop ball in position.
Fit in shift rod for reverse.

Position of stop and locking balls.

Turn gearshift shaft to reverse gear position.
Insert gearshift shaft for 1st gear and 2nd gear.

Insert gearshift shaft for 3rd gear and 4th gear.
Fasten shift forks with 2 tension pins each.

Insert sealing caps with sealing compound.

Fit in shift lever (1) for reverse gear lever and fasten.
Important: The shift lever must not be fitted in with a slant.

Fit on casing.
Build in reversing light switch and fastener for gearshift
shaft.
Heat inner ring of grooved ball bearing to approx. 80° C
(176° F) and fit onto layshaft.
Heat inner ring of grooved ball bearing to approx. 80° C
(176° F) and force onto drive shaft by means of tool No. 611
(tight fit).

Force drive shaft with grooved ball bearing into gearbox
casing (tight fit).

Fit on supporting ring.
Fit on circlip.
Compensate grooved ball bearing form drive shaft and
layshaft to guide flange to zero position.
Gap A between grooved ball bearing and drive shaft e. g.
7.0 mm (0.2756").
Gap B between grooved ball bearing and countershaft
e. g. 4.6 mm (0.1811").

Place sealing on guide flange.
Depth C e. g. 7.5 mm (0.2952") drive shaft
Depth D e. g. 5.3 mm (0.2086") layshaft
