Measure and adjust axial play of transmission

Transmission

725.0 in model 907

1

Place transmission housing (1) onto  parallel gauges (12).

2

Place measuring sleeve (2) onto transmission housing (1).

3

Place depth gauge (3) onto measuring sleeve (2) and reset depth gauge (3) to value of 0 mm.

4

Move depth gauge (3)  to parallel gauge (12) through the bore in the measuring sleeve (2) and determine dimension between measuring sleeve (2) and  parallel gauge (12) then note down.

5

Calculate dimension A1 and note down: Determined dimension - 50 mm (fixed dimension (measuring sleeve (2)) = dimension A1
For example, 469.10 mm – 50.00 mm = 419.10 mm

6

Insert measuring block (4) into transmission mount.

7

Apply a force of 400 N to measuring block (4).

 Crank the transmission several times so that the transmission mounts settle.

8

Place depth gauge (3) flat onto  measuring post (6), move to measuring block (4) with depth gauge (3) and reset depth gauge (3) to value of 0 mm.

9

Move depth gauge (3) up to measuring ring (5) and measure and note down dimension.

10

Calculate interim value and note down: Fixed dimension (measuring block (4)) 55 mm - determined dimension = interim dimension.
For example, 55.00 mm – 13.91 mm = 41.09 mm

11

Calculate dimension B1 and note down: (Fixed dimension for measuring post (6)) 370 mm - interim dimension = dimension B1
For example, 370.00 mm – 41.09 mm = 328.91 mm

12

Place measuring post (6) and  drift (10) on  parallel gauges (12).

13

Place coupling K 27 (9) onto  drift (10).

14

Place depth gauge (3) onto measuring post (6), move to seat (7) of deep-groove ball bearing with depth gauge (3) and reset depth gauge (3) to value of 0 mm.

15

Remove coupling K 27 (9) from  drift (10).

16

 Move to drift (10) with depth gauge (3), determine dimension C1 e.g. 88.58 mm and note down.

17

Determine shim thickness: Dimension A1 - dimension B1 - dimension C1 = interim value
Interim value - play 0.3 mm = shim thickness
For example, 419.10 mm - 328.91 mm - 88.58 mm = 1.61 mm - 0.3 mm = 1.31 mm

18

Install shim of the determined thickness.
