2.9.4 Pinion shaft bearing assembly
Place spacing washer (1) H1 2 mm on the gearbox housing with the oil grooves; the
oil grooves must be on the side of the four-point bearing (2).
The oil grooves serve to lubricate the bearing. A
reversal of the installation direction leads to bearing
damage from lack of lubrication.
Put on the four-point bearing (2) with the label in the direction of the retaining frame
pinion shaft (4)
Screw the pinion shaft retaining frame in place on the gearbox housing with 4 nuts (5)
The adjusting disk H2 (3) is not inserted yet because
its thickness is not determined until the next step.
Determining adjusting disk H2
The four-point bearing must be fitted with a compression of 0.03 mm in the retaining
frame of the pinion shaft. The compression is calculated as follows:
Fix the probe indicator (1) in place on the retaining frame with bracket (3) no. 37.
Apply probe indicator needle (2) to four-point bearing with prestressing through the
hole in the retaining frame.
Check the clearance between retaining frame and bearing; move the bearing evenly
from the bottom stop to the upper stop (retaining frame) for that (direction of the
arrow).
Add the measured free travel to the compression (0.03-0.05) and insert an
appropriate adjusting disk H2 (3) between retaining frame and four-point bearing.
Base washer H2 has a thickness of 2.18 mm.
Put on the retaining frame
Loosely put on the nut!
Do not tighten the retaining frame nuts yet. The four-
point bearing must first be centered (see chapter
2.9.5)!
