-
Tighten the screw which tensions the camshaft. Tighten to 12 Nm.
Checking the valve clearance
NOTE: Measurements should only be taken on a cold engine. A suitable temperature is approximately 20 degree C.
Use feeler gauge 999 5752.
Press with a finger so that the feeler gauge lies parallel to the upper side of the valve lifter (see above figure).
Move the feeler gauge sideways when taking the reading in order to obtain as accurate a measurement as possible.
The valve clearance measured on cold engines (approximately 20 degree C) should be:
Inlet valve:......................................................................................................................................................................................................0.20 ± 0.03 mm.
Exhaust valve:.................................................................................................................................................................................................0.40 ± 0.03 mm.
NOTE: The tolerances are less at setting. When checking the valve clearance through the plug hole the tolerances are larger.
Differences in valve clearance for different engines/ambient temperatures:
- 0.01 mm at 15 degree C
+ 0.01 mm at 25 degree C
+ 0.02 mm at 30 degree C
+ 0.03 mm at 35 degree C
+ 0.04 mm at 45 degree C
Correcting measured clearance
-
Lift out the upper section of the press tool.
-
Lift out the camshaft.
-
Adjust the play by replacing the valve lifters.
Other valve lifters are available as replacement part/replacement part kits.
Reinstall the camshaft and the upper section of the press tool. Tighten to 12 Nm.
Take a new measurement.
