II - VALVE CLEARANCE MEASUREMENT
OPERATION
- Turn the crankshaft accessories pulley clockwise
and align the TDC mark (3) and the mark (2) located
on the timing cover.
- Use a feeler gauge to measure the clearance between
the valve tappet and the camshaft.
Note: Valve clearance:
- inlet:
0.24~0.32 mm (cold),
0.304~0.416 mm (hot: 80ºC).
- exhaust:
0.26~0.34 mm (cold),
0.308~0.432 mm (hot: 80ºC).
|
- Measurement positions (cylinder no. 1 at TDC):
- Cylinder no. 1: inlet and exhaust,
- Cylinder no. 2: inlet,
- Cylinder no. 3: exhaust.
- Measure the valve clearance in the locations indicated
by a black arrow on the diagram using a feeler
gauge.
- Turn the crankshaft accessories pulley one turn
(360º) to align the TDC mark (6) and the mark (5) located
on the timing cover.
- Referring to the diagram, measure the valve clearance
in the locations indicated by a black arrow in
the diagram using a feeler gauge
- Measurement positions (cylinder no. 4 at TDC):
- Cylinder no. 2: exhaust,
- Cylinder no. 3: inlet,
- Cylinder no. 4: inlet and exhaust.
