Checking/adjusting fully assembled length of
output shaft
e
Caution:
Check and adjust the fully assembled length as de-
scribed below and install a spacing washer of the
correct thickness.
Before measuring, always make sure that the
grooved ball bearings are pressed fully home, even
if the shaft has not been disassembled and reas-
sembled.
•
Pull off output-side deep-groove ball bearing
with universal puller, BMW No. 00 7 500.
•
Remove the spacing washer.
•
Locate dial gauge, BMW No. 23 4 762, in rear
bore of measuring fixture, BMW No. 23 4 761,
and set to 0.2 mm (0.008 in) preload.
•
Using dial gauge, zero to distance "A" of the zero
gauge, BMW No. 23 4 763.
•
Place reference washer, BMW No. 23 4 766, on
the output shaft.
•
Place the grooved ball bearing on the reference
washer.
•
Insert the output shaft into the measuring stand.

•
Using the dial gauge, measure the deviation from
zero of distance "B" at the inner bearing race.
Deviation from zero is equivalent to the thickness
"C" of spacer (1).
•
Place spacer (1) of correct thickness on inner
bearing race and check deviation from zero.
A = B + C
e
Caution:
The maximum deviation from zero must not be ex-
ceeded.
•
Take off spacer, grooved ball bearing and refer-
ence washer.
•
Place a spacing washer (1) of the correct thick-
ness on the output shaft and press on the
grooved ball bearing.
Reference dimension for output shaft:
Maximum deviation
from zero ....... -0.05 ... 0.00 mm (-0.002 ... 0.00 in)
