VALVE CLEARANCE CHECK AND ADJUSTMENT
NOTE: Check and adjust clearance when the engine is cold.
1. If equipped, remove air deflector from top of engine.
2. Remove rocker cover.
3. Turn the crankshaft until the piston is at top dead center of the compression stroke (Figure 22-5, Page 22-7) .
4. Using a feeler gauge (1), measure the clearance between the adjuster screw (3) and the top of the valve stem
(Figure 22-6, Page 22-7) .
5. If necessary, loosen the lock nut (2) and turn the adjuster (3) up or down to adjust the clearance to 0.0047 in.
(0.12 mm) for both intake and exhaust. Once clearance is correct, tighten the lock nut (2) to 52 in·lb (6 N·m).
6. After adjusting valve clearances, rotate the crankshaft several full revolutions and verify that the intake and
exhaust valve clearance are still correct.
At TDC, the two punch marks on cam sprocket are parallel with the
cylinder head surface.
