7 Series E32 740iL (M60-2) SAL
If the specified friction torque is not achieved although both
bearing covers have been tightened to the specified tightening
torque,
refer to Technical Data 33 11 2AZ,
a thinner shim must be installed at the crown wheel end and the
measurement must be repeated.
If the friction torque level is achieved even though the second
bearing cover has not been tightened to the specified tightening
torque, a thicker shim must be installed at the crown wheel end
and the measurement must be repeated.
To simplify calculation of the shim thickness, the distance between
shim and transmission case must be measured with a feeler
gauge and added to the shim thickness fitted.
Example:
Bearing cover at crown wheel end not tightened down (screws
tightened uniformly). Friction torque specified on bearing set
packaging 180 Ncm.
1 output flange fitted
New shaft seal = 20 Ncm
Measured friction torque = 200 Ncm
Gap measured with feeler gauge = 0.20 mm
Shim used = 1.40 mm
New shim = 1.60 mm
Install new shims, 1.60 mm gage, and repeat measurement.
Once the friction torque has been established, remove final drive
and mark shims used in bearing cover and transmission.
