Checking/adjusting fully compressed
length of gearbox shafts and selector
drum
Checking/adjusting fully-compressed length of
intermediate shaft
e Caution:
To adjust and check the fully-compressed length,
measure deviation from zero as described below
and adjust with a shim washer.
Before each measurement, even if the shaft is not
being installed, make sure that the deep-groove ball
bearing is fully compressed.
•
Pull off the input-side deep-groove ball bearing
with universal puller, BMW No. 00 7 500.
•
Take off the spacing washer.
•
Insert zero gauge, BMWNo.234763, into
measuring stand, BMW No. 23 4 761.
•
Secure dial gauge, BMW No. 23 4 762, in rear
mounting hole on measuring stand,
BMW No. 23 4 761, and set to 0.2 mm (0.008 in)
preload.
•
Using the dial gauge, zero to dimension “A” of
the zero gauge, BMW No. 23 4 763.
•
Remove the zero gauge from the measuring fix-
ture.
•
Place measuring disc, BMWNo.234765, on
the intermediate shaft.
•
Place deep-groove ball bearing on measuring
disc.
•
Insert intermediate shaft in measuring stand.
•
Using dial gauge, measure deviation from zero of
dimension “B” at inner bearing race.
The deviation from zero is equivalent to the thick-
ness “C” of spacing washer (1).
•
Place a spacing washer (1) of the thickness just
determined on the inner bearing race and check
deviation from zero.
A = B + C
e Caution:
The maximum permitted deviation from zero must
not be exceeded.
•
Remove the intermediate shaft from the measur-
ing fixture.
•
Take off spacing washer, the deep-groove ball
bearing and the measuring disc.
•
Place a spacing washer (1) of the determined
thickness on the intermediate shaft and press on
the deep-groove ball bearing.
