Dismantling the bogie differential lock

1

Remove the cover 51, diaphragm 50 and 
piston 49 for the differential lock. Take out 
the differential lock.

2

Remove the switch 48.

3

Unscrew shaft 44 and take out the levers
40 and 42 with spring 41.

Assembly

1

Press the rear pinion bearing 10 onto the 
pinion using drift 87 550 and 99 092.

2

Fit the oil collector into the gear housing. 
Apply locking compound to the bolts and 
tighten them.

3

Press the front pinion bearing outer ring 7 
into the gear housing using assembly sleeve 
98 524, drift 87 247 and shank 98 450.

4

Turn over the housing and fit the shims 11 
that were used earlier under the rear pinion 
bearing outer ring.

5

Fit the setting ring 98 779 instead of the rear 
pinion bearing outer ring. This has a slightly 
smaller outer diameter, which makes it 
easier to change the number of washers.

6

There is a two-digit number painted on the 
pinion. This is the deviation measurement A 
given in hundredths of a mm. The pinion 
setting dimension is 0.50 + A +/- 0.05 mm.

7

Lubricate the running surface of the ring 
with oil. Fit the pinion and rotate it a few 
turns so the rollers take their correct 
positions.

8

Place the pinion position template 99 072 in 
the bottom of the differential bearing seat. 
Make sure the template is vertical and 
parallel to the centre line of the differential. 
Hold down the template lightly so it does 
not wobble when measuring.

9

Measure the setting dimension of the pinion 
with a feeler gauge between the end plane of 
the pinion and the template.

Example: The number 58 is on the pinion. 
This gives a setting dimension of 
0.50 + 0.50=1.08. The setting dimension 
must be 1.03 - 1.13 mm.

10 Adjust if necessary by changing shims 

between the pinion bearing housing and the 
gear housing.

Shims are available in thickness 0.25, 0.30 
and 0.40 mm.

11 Remove the pinion and the setting ring. 

Instead of them, press in the outer bearing 
ring belonging to the bearing using support 
ring 98 613, drift 98 566 and shank 98 450.

12 Place the pinion on a bench and fit the 

spacing ring 12 and the shims 13 that were 
fitted originally. Apply grease to the contact 
surfaces so they adhere to each other and to 
the bearing.

13 Turn over the gear housing so that the front 

section points down as illustrated.

Unsplined side up

14 Insert the pinion transfer gear 4 into the gear 

housing with the unsplined section of the 
hub facing the rear end of the housing 
(upward).

15 Insert the pinion into the gear housing. 

Make sure the transfer gear splines engage 
in those on the pinion.

16 Carefully drive down the pinion far enough 

to screw on the nut 8.
