Checking valve clearance at two
crankshaft positions
1. Check TDC position of piston in cylinder A1:
If the rocker arms are not under load on
cylinder A1, the piston is in firing TDC.
If the rocker arms are under load on cylin-
der A1, the piston is in overlap TDC.
2. Check valve clearance with the engine cold:
Inlet = 0.4 mm;
Exhaust = 0.6 mm;.
3. Check all valve clearances in two crankshaft
positions (firing TDC and overlap TDC of cyl-
inder A1) as per diagram:
1 Cylinder A1 is in firing TDC
2 Cylinder A1 is in overlap TDC
I Inlet valve
X Exhaust valve
4. Use feeler gauge to determine the distance
between valve bridge and rocker arm.
5. If the deviation from the set value exceeds
0.1 mm, adjust valve clearance.
Adjusting valve clearance
1. Loosen locknut (1) and unscrew adjusting
screw (2) slightly.
2. Insert feeler gauge between valve bridge and
rocker arm.
3. Readjust adjusting screw (2) so that the feel-
er gauge just passes through the gap.
4. Tighten locknut (1) applying the specified tightening torque, holding adjusting screw (2) firmly with screwdriv-
er.
