6.Valve clearance inspection
and adjustment can be performed on rocker arms indicated by
white arrow mark when the No. 1 cylinder piston is at the
top dead centre on the compression
stroke, and on rocker arms indicated by black arrow mark
when the No. 4 cylinder piston is at
the top dead centre on the compression
stroke.
7.Measure the valve clearance.
If the
valve clearance is not as specified, loosen the rocker arm
lock nut and adjust
the clearance using a thickness gauge while turning the
adjusting screw.
Standard value (cold
engine):
| note |
Valve clearance check and
adjustment is unnecessary for exhaust side due
to auto lash
adjuster installed.
