Valve Clearance Check And Adjustment - Club Car Precedent 2016 Maintenance And Service Manual

ENGINE – SUBARU EX40
Oil laden air in the crankcase passes through the reed valve and expands into the rocker chamber. In the rocker
chamber most oil separates from the air and drains back to the crankcase. The air passes through a tube and
vents to the intake manifold.

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 20-5, Page 20-7).
4. Using a feeler gauge (1), measure the clearance between the adjuster screw (3) and the top of the valve stem
(Figure 20-6, Page 20-7).
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.
