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).
NOTE
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)
NOTE
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!
NOTE
Version: 16.12.2014
The oil grooves serve to lubricate the bearing. A
reversal of the installation direction leads to bearing
damage from lack of lubrication.
The adjusting disk H2 (3) is not inserted yet because
its thickness is not determined until the next step.
Do not tighten the retaining frame nuts yet. The four-
point bearing must first be centered (see chapter
2.9.5)!
