– Install measuring tools and secure to clutch housing with bolt
-arrow-.
– Set -VAS 6080- (3 mm measuring range) to 0 with 1 mm pre‐
load.
– Loosen securing bolts for clutch housing/transmission housing
in diagonal sequence until bolts clear transmission housing
and output shaft.
– Read measured value on dial indicator and note (example:
0.14 mm).
Note
If no measured value is displayed on the dial gauge when loos‐
ening the securing bolts for the clutch housing/transmission hous‐
ing, install adjustment shim 1.95 mm (part number
-084 409 383 AS- ) or if necessary 2.20 mm (part number
-084 409 383 BD- ) for the measurement.
Determining Shim Thickness
The specified bearing pre-load is reached when determined
measured value (0.14 mm) is subtracted from inserted adjust‐
ment shim (1.70 mm) and a constant pre-load value (0.20 mm) is
added.
Example:
Installed adjustment shim 1.70 mm
– Measured value 0.14 mm
+ Pre-load (constant value) 0.20 mm
Thickness of shim 1.76 mm
– Determine the adjustment shim thickness according to the ta‐
ble; part number, refer to the electronic parts catalog ETKA.
The following shims are available:
Thickness of Shims in mm
1.45 1.70 1.95 2.20
1.50 1.75 2.00 2.25
1.55 1.80 2.05
1.60 1.85 2.10
1.65 1.90 2.15
Different shim thicknesses make it possible to select the required
thickness precisely.
– Remove the transmission housing and pull the tapered roller
bearing outer ring out of the transmission housing.
A - Support , for example -Kukko 22/2-
B - Internal puller 46 to 58 mm , for example -Kukko 21/7-
– Remove inserted adjustment shim (1.70 mm thick) from trans‐
mission housing.
