Refinishing flywheel - ra03006010420x(0420)
WARNING: This page does not describe the selected car, but rather 42 other vehicles, including the 1999 Mercedes-Benz S600, 1999 Mercedes-Benz S500, 1999 Mercedes-Benz S420, 1999 Mercedes-Benz S320, and 1999 Mercedes-Benz CL600. However, it is still accessible from the selected car via links, so may be relevant.
Engines 601, 602 (except 602.98), 603
Preliminary jobs:
Flywheel and driven plate removed (03-410).
Operation No. of operation texts and operation values or standard texts and flat rates 03-8022
| Dimension (b) | measure, max. 17 mm, min. 15.6 mm. If dimension (a) has become so great due to material removal that dimension (b) is less than 15.6 mm, renew flywheel. |
| Dimension (a) | measure, engines 601, 602: 22.5 mm, engine 603: 19.4 mm. Maximum material removal 1 mm, if material removal is greater than 1 mm, renew flywheel. |
If the clutch surface (A) is refinished, the mounting surface (B) must be refinished by the same dimension so that distance (a) is maintained. |
|
| Flywheel | refinish |
The two-mass flywheel cannot be refinished. Clamp flywheel in lathe so that permissible deviation from flat = 0.05 mm is not exceeded. |
DATA
| Engine | 601, 602 603 | |
| Distance a | 22.5 ± 0.1 19.4 ± 0.1 | |
| Distance b | in new state | 16.6 ± 0.4 |
| for repair | up to 15.6 ± 0.4 | |
| Permissible deviation from flat on clutch surface or clutch attachment surface | 0.05 mm |
NOTE:
Flywheels for manual transmissions with burned spots, scoring or cracks on the clutch surface should be refinished by precision turning.
If the scoremarks or cracks are greater than the maximum permissible material removal dimension, renew flywheel.
After machining the clutch surface should not have any porous spots or chatter marks.
