8022 - Machining flywheel Engines 601.940/941, 602.940

Preceding work:

Flywheel removed (03-8001).

Note

The two-mass flywheel of engine 602.940 must not be machined.

Distance (a) in mm

19.4 0.1

Distance (b) in mm

when new

16.6

for repairs up to

15.6

Maximum axial runout in mm

0.05

Permissible peak-to-valley height

Rz 2.5 - Rz 6.3

Note

Flywheels of mechanical transmissions which have scorch marks, scoring or cracks in the clutch surface should be machined by grinding or precision-turning.

If the scores or cracks are deeper than the maximum permissible stock removal, the flywheel must be replaced.

After machining, the clutch surface must not display any shrink holes or chatter marks.

When machining the clutch surface (A), ensure that the distance (a) is always maintained.

The mounting surface (B) for the clutch should therefore be machined in accordance with the stock removal at the clutch surface (A).

The stock removal at the clutch surface (A) must not exceed 1 mm.
