Caution!
- Check and adjust the fully assembled length as described 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 reassembled.
Position dial gauge, BMW No. 23 4 762, in front locating bore of stand, BMW No. 23 4 761, and set to 0.2 mm (0.008 in) preload.
Using dial gauge, zero to dimension «A» of the zero gauge, BMW No. 234763.
Pull off the output-side grooved ball bearing with universal puller, BMW No. 007500.
Remove the spacing washer.
Mount reference washer, BMW No. 23 4 764, on the input shaft.
Place the grooved ball bearing on the reference washer.
Insert input shaft with adapter disc, BMW No. 234767, in measuring stand.
Using the dial gauge, measure deviation from zero of dimension «B» at the inner bearing race.
Deviation from zero is equivalent to the thickness «C» of spacer (1).
Place a spacer (1) of the correct thickness on the bearing inner ring and check deviation from zero.
A = B + C
Caution! The maximum deviation from zero must not be exceeded.
Take the input shaft out of the measuring fixture.
Remove the adapter disc, spacing washer, grooved ball bearing and reference washer.
Place a spacing washer (1) of the correct thickness in position and press the grooved ball bearing on to the input shaft.
Reference dimension for drive shaft:
- Maximum deviation from zero: -0.05…0 mm (-0.002...0.00 in)
