Determine shim

1

 Attach clamping plate (2).

2

Screw in screws (3) on  clamping plate (2) uniformly using  torque wrench   .

 Only use a  torque wrench with slave pointer.
Otherwise the bearing outer race (6) may be damaged.

 Tighten screws (3) on  clamping plate (2) in at least 2 stages.

3

Spin drive shaft back and forth several times so that the bearings settle.

 The splitter group must be engaged during this. Observe position of splitter box cylinder.

4

Tighten screws (3) on  clamping plate (2) again uniformly   .

 Repeat tightening procedure until the tightening torque no longer changes.

5

Loosen screws (3) on  clamping plate (2) and tighten gently by hand.

6

Use vernier caliper to measure dimension (E) from bearing outer race (6) of countershaft to housing contact surface.

 Measure dimension (E) at two opposite points and determine the mean value.

7

Remove retaining ring (8) from countershaft brake housing (7).

8

Measure dimension (D) of retaining ring (8) with outside micrometer.

9

Measure dimension (F) at countershaft brake housing (7) from separating surface to contact surface of retaining ring (8) using vernier caliper.

10

Calculate shim for bearing of countershaft.  

 Dimension (F) - dimension (D) - dimension (E) = thickness of shim to be installed.
A play of 0.0 mm should be aimed for.

11

Install retaining ring (8) in countershaft brake housing (7).

12

 Detach clamping plate.
