17 Turn the gear housing and place the pinion 

on support drift 98 332, drift 99 253 and 
assembly drift 98 364.

18 Press in place the transfer gear using drift 

87 932.

19 Fit the spacing ring 6 and the front pinion 

bearing 7. Use drift 87 932 to press together 
the bearings with max. 70-80 kN. Rotate the 
gear housing at the same time. Stop pressing 
if the gear housing becomes difficult to 
rotate and change to a thicker shim or longer 
spacing ring.

Note: The larger diameter of the spacing ring 
must be placed against the transfer gear.

20 Attach a dynamometer to the gear housing 

in the hole closest to the differential lock 
operation. Measure the force required to 
rotate the gear housing.

The bearing preload is correct when the 
rolling resistance measured with the 
dynamometer is 8-14 N with worn bearings 
and 25-45 N with new bearings at a press 
force of 70-80 kN.

Shims are available in thickness 0.30, 0.40 
and 0.50 mm.

Spacing rings are available in lengths 22.48, 
22.50, 22.52, 22.54 and 22.56 mm.

21 Lay a wooden board on the press bench for 

the pinion to fall onto. Press out the pinion 
with drift 99 135. Keep the shims and 
spacing rings. Take out the transfer gear. 
The pinion is to be refitted when the planet 
wheel carrier has been adjusted.

22 Turn over the gear housing so that the front 

section points down as illustrated.

23 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).

Unsplined side up 

24 Fit the planet wheel carrier transfer gear 37 

with the unsplined side of the hub towards 
the front cover (downward).

25 Lift up the gear housing and place it on the 

planet wheel carrier, aligning the splines on 
the transfer gear with the corresponding 
splines on the planet wheel carrier.

26 Fit spacing ring 36 and bearing 38 and press 

lightly on the inner bearing ring using two 
thrust elements 98 614, drift 99 221 and 
shank 98 450.

27 Rotate the gear housing while increasing the 

press force on the bearing up to 70-80 kN.

28 Mount the dial gauge 98 075 on the 

magnetic foot in the gear housing. The tip of 
the dial gauge must rest against drift 99 221. 
Zero the dial.

29 Lift up the housing with two crowbars and 

read the bearing clearance. The clearance 
should be 0.02-0.10 mm.

Adjust the bearing clearance if necessary by 
changing shims of spacing ring.

Shims are available in thickness 0.30, 0.40 
and 0.50 mm.

Spacing rings are available in lengths 12.30, 
12.32, 12.34, 12.36 and 12.38 mm.

30 Fit locking tool 98 615.

31 Tighten the nut 38 with key 98 440. 

Tightening torque 400 Nm.

32 Lock the nut by staking its collar into the 

four grooves in the planet wheel carrier.

33 Refit the pinion, see "Adjusting pinion 

position and bearing preload", points
14-19. Tighten the nut using socket 98 480. 
Tightening torque 600 Nm.

34 Remove the locking tool 98 615 and fit the 

cover 55 with a new gasket 54 over the 
transfer gear.

35 Fit the cover over the pinion nut. Insert the 

cover under the planet wheel carrier and 
drive down the cover with a plastic hammer.
