•
Valve clearances should be checked and adjusted as follows
while the engine is still cold.
[Inspection]
•
Remove the rocker cover.
•
Bring the No. 1 or No. 6 cylinder piston to the top dead center
(TDC) on the compression stroke according to the following pro-
cedure:
•
Rotate the crankshaft until the pointer is aligned with the “1 6”
mark on the flywheel.
•
This will place either the No. 1 or No. 6 cylinder piston at TDC
on the compression stroke. The cylinder in which the rocker
arms for both the intake and exhaust valves can be pushed
down by hand by the valve clearance amounts has its piston
at TDC. Rotate the engine by one full turn to switch the TDCs
of the No. 1 and No. 6 cylinder pistons.
•
With the No. 1 or No. 6 cylinder piston at TDC, measure the
clearance of the valves (clearance between valve bridge and
pad) marked with a circle in the table below.
