• Before inserting a feeler gauge, push the adjusting screw pad on
the side opposite from where a feeler gauge is to be inserted, as
shown in the illustration, using a flat-blade screwdriver or other
similar tool. This will create space necessary for the gauge to be
inserted.
• The measurement is correct when the feeler gauge feels slightly
resisted as it is inserted.
• The measurement is not yet correct if the feeler gauge can still
be inserted smoothly.
• If the measurement deviates from the standard value, adjust as
follows.
[Adjustment]
• Loosen the lock nuts and adjusting screws on the valve bridge
and rocker arm.
• While holding the valve bridge by hand, screw in the adjusting
screw until it lightly contacts the valve stem end.
• Then, further screw in the adjusting screw by 45°.
• While holding the adjusting screw in this position, tighten the
lock nuts to the specified torque.
CAUTION
• After adjusting the adjusting screw, be sure to tighten the
lock nut to the specified torque. Insufficient torquing will
compromise the parallelism of the valve bridge, damaging
the valve mechanism.
