Checking and adjusting axial play of input shaft
1 Place dial indicator holder (2) with dial indicator (1) onto sealing surface of cover for drive shaft and countershaft, and then position probe with preload onto bearing seat of drive shaft tapered roller bearing (3).
2 Set scale of dial indicator (1) to "0" (note position of small pointer).
D28.50-0025-01
3 Fit bearing outer race (5) without play using strip clamps (4) while spinning the input shaft (6).
The tapered roller bearing is without play when the rollers can still be turned easily.
4 Place dial indicator holder (2) with dial indicator (1) onto bearing outer race (5) of drive shaft tapered roller bearing and place probe onto sealing surface of rear housing section.
5 Read off and note measurement difference on dial indicator (1).
6 Determine thickness of shim.
The shim must be thinner than the
amount of the axial play specified in the table.
D28.50-0026-01
Checking and adjusting axial play of countershaft
7 Place dial indicator holder (2) with dial indicator (1) onto sealing surface of cover for drive shaft and countershaft, and then position probe with preload onto bearing seat of the countershaft tapered roller bearing (7).
8 Set scale of dial indicator (1) to "0" (note position of small pointer).
D28.50-0023-01
9 Fit bearing outer race (5) without play using strip clamps (4) while spinning the input shaft (6).
The tapered roller bearing is without play when the rollers can still be turned easily.
10 Place dial indicator holder (2) with dial indicator (1) onto bearing outer race (5) of the countershaft tapered roller bearing and place probe onto sealing surface of rear housing section.
11 Read off and note measurement difference on dial indicator (1).
12 Determine thickness of shim.
The shim must be thinner than the
amount of the axial play specified in the table.
