• Sealing surfaces of clutch and gearbox housings must be free
of sealant.
Carry out procedure as follows:
– Press small tapered roller bearing outer race together with a
0.65 mm thick shim into clutch housing to stop ⇒ page 173 .
– Insert output shaft and tighten nuts for bearing support to 25
Nm, then turn 90° further.
– Turn output shaft 20 to 30 times in one direction.
Note
♦ The shaft must be turned in one direction so that the rollers of
the tapered roller bearing settle in one direction.
♦ It is necessary to turn the shaft 20 to 30 times to achieve this.
♦ Otherwise the resulting reading will be incorrect.
– Set up dial gauge (3 mm measuring range) and set to “0”with
1 mm preload.
– Move output shaft up and down and note dial gauge reading
(example: 0.20 mm).
2.2.1 Determining thickness of shim
The specified bearing preload is obtained by adding a constant
preload figure (0.10 … 0.15 mm) to the reading obtained and the
thickness of the shim installed.
Example:
Installed shim
0.65 mm
+ Measured value 0.20 mm
+ Preload (constant) 0.15 mm
Shim thickness
Example:
1.00 mm
Bearing play = Thickness of shim according to
(0.65 mm shim
table
plus determined measured value)
0.850 mm 1.000 mm
– Remove output shaft and pull out small tapered roller bearing
outer race ⇒ page 173 .
