SL 600 (129.076) V12-6.0L (120.983) (1997)
Insert into adjusting slide (step 10).
Fixing device 119 589 00 21 00:
Must engage in measuring pin on vibration damper.
CORRECTING SETTING OF TDC SENSORS
Nuts of adjusting slide:
Slacken (step 11).
Adjusting slide:
Move until fixing device 119 589 00 21 00 engages at vibration damper (step 11).
Nuts of adjusting slide:
Tighten (step 12).
NOTES:
The TDC sensors (L1/2) and (L1/1) with adjusting slides (3) and (7) are attached to the timing case cover.
The measuring pin (arrow) on the vibration damper must be centered below the TDC sensors (L1/2) and (0/1) at 200 after TDC at cylinder 1° and at
20° after TDC at cylinder 7 (TDC pointer reading 80°).
The setting of the TDC sensors must be chocked and corrected:
^
if the crankshaft or the vibration damper is replaced.
^
if the timing case cover is replaced.
^
if parts are added to part engines.
With the cylinder heads removed, attach a dial gauge holder to the crankcase and position dial gauge pin on the piston crown.
