1 Fit spacer ring (5) to bearing collar.
The spacer ring (5) is only installed in the case of tapered roller bearings without a collar.
2 Use adjusting sleeve (3) to pre-tension tapered roller bearing. In doing so rotate the gear wheel at constant speed gear 2 (6) several times.
The tapered roller bearings are pre-tensioned sufficiently when the 2 (6) becomes difficult to turn.
3 Loosen adjusting sleeve (3) slightly.
4 Turn constant speed gear 2 (6) several times while tapping the constant speed gear 2 (6) using a plastic mallet.
To relieve jamming.
5 Screw on adjusting sleeve (3) again finger-tight.

6 Attach dial indicator (1) to adjusting gauge (2).
If the pin of the dial indicator (1) is too short, use extension.
7 Attach adjusting gauge (2) so that it slides on adjusting sleeve (3).
8 Use dial indicator (1) to measure collar of main shaft (4).
9 Set dial indicator (1) to zero.
10 Using dial indicator (1), measure distance to spacer ring (5) and to collar of tapered roller bearing in constant speed gear 2 (6), dimension "A".
11 Calculate thickness of shim to be fitted:
Dimension "A" - 0.20 mm = Thickness of shim to be fitted.

12 Using a suitable pulling device, pull off constant speed gear 2 (6) up to an axial play of approx. 1.0 mm.
13 Fit calculated shim (8) and pressure plate (7) to collar of journal.
14 Fit adjusting sleeve (3) and tighten until the pressure plate (7) has pushed the tapered roller bearing back into its installation position.
15 Attach dial indicator (1) to adjusting gauge (2).
16 Attach adjusting gauge (2) so that it slides on adjusting sleeve (3).
17 Position dial indicator (1) on ground surface of constant speed gear 2 (6) and turn constant speed gear 2 (6) approx. 20 times.
18 Set dial indicator (1) to zero.
19 Turn constant speed gear 2 (6) clockwise/counterclockwise slightly and, while simultaneously pushing up/down (arrows), read off bearing play at dial indicator (1).
Do not push constant speed gear 2 (6) up/down using a screwdriver or tire lever as this can result in measurement errors.
20 If there is any deviation, correct using appropriate shim (8) and repeat measuring procedure.
The objective is to have an axial play at the lowest tolerance limit.
