The procedure here is exactly the same as when building
a self-locking differential into a car not equipped
with this mechanism at the factory. In that case the only
exception is at the beginning: Remove differential housing and take
crown wheel (US: ring gear) off housing.
Removal of final drive cf. 33 10 010.
Removal of self-locking differential cf. 33 14 010.
Take crown wheel (US: ring grar) off self-locking differential.
Note when assembling: Fit on crown wheel (US: ring
gear) cold.
Clean bolt threads thoroughly.
Insert bolts with Loctite AVV.
Pull off taper roller bearing by means of Rollex 503349.
Note when assembling: Press on taper roller bearing cold.

¹) see Specifications

Build in new self-locking differential without crown wheel
(US: ring gear).
Tighten cap fastening bolts evenly (2.0 ± 0.5 mkp/
14.46 ± 3.615 ft./Ib.).
Measure frictional volue¹).
If the frictional value is lower than required, find out
size of gap and use corresponding shim.

By fitting shims (2) with the necessary thickness, adjust
torsional backlash and contact pattern as desired.
Move shims (2) from one side to the other until torsional
backlash¹) and the contact pattern are correct.
Make sure that the overall thickness of both shims together
is never changed.


¹) see Specifications.

If the contact pattern is not correct, adjust by means of
shim X. For doing this, basic rules of adjusting contact
pattern on page 33-12/11.
Important: Before unscrewing collar nut (1) check frictional
value. Make it a rule to always replace tensioning bush (2).
Adjust bevel drive pinion bearing to the frictional value
measured prior to disassembly. When doing this, make sure
that the collar nut is tightened to a torque of at least
15 mkp (108.45 ft Ib) . If this value of 15 mkp (108.45 ft Ib)
is not reached or if it is exceeded, replace tensioning bush
(2) and pepreat the measuring process.
