crankshaft positions)
Checking valve clearance at two crankshaft positions
1.
Check TDC position of piston in cylinder A1:
• The piston is in firing TDC when the rocker arms on cylinder A1 are unloaded.
• The piston is in overlap TDC when the rocker arms on cylinder A1 are loaded.
2.
Check valve clearance setting with engine cold:
• Inlet (long rocker arm) = 0.2 ±0.05 mm
• Exhaust (short rocker arm) = 0.5 ±0.0 5mm
3.
Check all valve clearances in two crankshaft positions (firing TDC and overlap TDC of cylinder 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.
Adjust valve clearance if the deviation from the set value exceeds 0.1 mm.
