VALVE COMPONENTS AND
CYLINDER HEADS
1. Lubricate valve stems and insert into valve
guides. Intake valves toward flywheel side of
engine, exhaust valves toward P.T.O. end.
Valves will be marked "IN" for intake and "EX"
for exhaust.
2. Rotate camshaft to position where cam has no
effect on tappets-hold valve firmly on seat and
check clearance between valve stem and tappet.
Intake valve clearance (cold) should be between
.003" and .006", and exhaust valve clearance
(cold) is between .011" and .014" (see Figure 8-
27). If clearance is insufficient, grind end of
valve stem until correct clearance is attained.
Make sure stem is ground perfectly flat.
