-
Because of the different thicknesses of the shims, the required shim thickness for "S3" may be produced by using more than one shim.
^
Remove universal measuring bar.
^
Remove pinion and outer race of large tapered roller bearing, and install again with selected shim and spacer.
^
Install inner race of small tapered roller bearing.
^
Install drive shaft flange and tighten nut until specified turning torque is achieved.
Notes:
^
Do not additionally treat new tapered roller bearings to measure the turning torque. For this purpose, the bearings are already pretreated with a
special oil.
^
Increase the tightening torque slowly, while reading the turning torque several times. If the specified turning torque is exceeded, the spacer sleeve
must be replaced and the adjustment repeated. A spacer sleeve that has been compressed too much one time cannot be used again.
Turning torque specifications
Carrying out control measurement
^
Check dimension "r."
^
Turn pinion in both directions at least 5 revolutions.
^
Install universal measuring bar and carry out control measurement.
If shims are correctly selected, the dial indicator, read in a counterclockwise direction (red scale range), must display the value of the dimension "r"
