Prepare for the measurement
1 Fit the bolts (3) in the tensioning plate (1) in the position (G 210-G 280).
2 Assemble the tensioning plates (1, 2) in the location bearing covers of the input an intermediate shaft .
IN gearboxes up to the final number041830 in the tensioning plate installation (2) must be shimmed with four nuts M10.
3 Tighten the bolts (3) in the tensioning plates (1, 2) evenly using a torch wrench .
Tighten the bolts (3) at least two turns.
4 Turn the input shaft from one side to another several times, so that the bearing seat.
For that, the scaling group must be engaged.
5 Repeat the work steps 3 and 4 twice more, so that the bearing seat.
6 Release the bolts (3) and tighten them manually.
Do not use tool to tighten.

Determine the compensation washer for the input shaft
7 With a caliper, check the measurement (A) of the bearing external ring (4) of the input shaft with the housing contact surface.
Measure in two opposite positions. The average value of the two positions checked will result in the measurement (A).
W26.50-1091-01
8 With a caliper, check the measurement (B) of the contact surface to the external bearing support surface of the input shaft cover(5).
Measure in two opposite positions. The average value of the two positions checked will result in the measurement (B).
W26.50-1092-01
9 Calculate the compensation washers for the input shaft bearing:
Measurement (B) – measurement (A) = measurement (C).
It must aim a pre-load of 0.05 mm.
The compensation washer to be installed must be thicker than the measurement (C) of the pre-tension specified in the table.

Determine the compensation washer for the input shaft
10 With a caliper, measure the measurement (E) of the bearing external ring (6) of the intermediate shaft to the housing contact surface.
Measure in two opposite positions. The average value of the two positions checked will result in the measurement (E).
W26.50-1094-01
11 With a caliper, measure the measurement (F) of the intermediate shaft cover contact (7) to the support surface of the bearing external ring of the cover.
Measure in two opposite positions. The average value of the two positions checked will result in the measurement (F).
W26.50-1095-01
12 Calculate the compensation washers for the intermediate shaft bearing:
Measurement (F) – measurement (E) = measurement (H).
It must aim a play of 0,0 mm in the bearing.
The compensation washer to be installed must correspond to the measurement (H).
The compensation washer can be different from the adjustment tolerance indicated in the table.
13 Remove the input and intermediate shaft tensioning.
