Measuring and adjusting axial play of input shaft

Transmission

1

Place depth gauge (2) at top, flat onto measuring post (1), move to pulse ring (4) with depth gauge (2) and reset depth gauge (2) to value of 0 mm.

2

Place measuring sleeve (3) on drive shaft.

3

Move depth gauge (2) up to measuring sleeve (3) and measure dimension.

4

Calculate dimension and note down dimension L1: Determined dimension + (fixed dimension of measuring sleeve (3)) 70 mm = dimension L1.
For example  33.06 mm + 70.00 mm = 103.06 mm.

5

Remove measuring sleeve (3) from drive shaft.

6

Insert ring gear and planet carrier.

7

Place test adapter (5) onto axial bearing of planet carrier.

8

Apply a force of 400 N to test adapter (5).

9

Place depth gauge (2) flat onto measuring post (1), move to test adapter (5) with depth gauge (2) and reset depth gauge (2) to value of 0 mm.

10

Move to pulse ring (4) with depth gauge (2), determine dimension and note down.

11

Calculate dimension and note down dimension L2: (fixed dimension of measuring adapter (5)) 104 mm - determined dimension = dimension L2.
For example  104.00 mm – 14.31 mm = 89.69 mm.

12

Remove adjusting ring from planet carrier (7).

13

Place measuring post (1) and measuring sleeve (8) on  parallel gauges.

14

Place planet carrier (7) onto measuring sleeve (8).

15

From measuring post (1) move with depth gauge (2) up to inner race (6) and reset depth gauge (2) to value of 0 mm.

16

From measuring post (1), move depth gauge (2) up to bearing washer (9), and measure and note down dimension L3.

17

Determine shim thickness: Dimension L1 - dimension L2 - dimension L3 = interim value - 0.10 mm = shim thickness.
For example  103.06 mm - 89.69 mm - 10.62 mm = 2.75 mm - 0.1 mm = 2.65 mm.

18

Install shim of calculated thickness.
