9-4-7 TAPPET ADJUSTMENT

Set the tappet at the lowest point and push down the valve. Measure the clearance between the valve and the tappet stem, using a clearance gauge inserted into the clearance (See Fig. g-4-12).

Note: When the engine is not running, the clearance between the valve and tappet stem must be in the range of 0.110.02. This holds true for both the intake valve and the exhaust valve.

Note: If the clearance is smaller than the specified one, grind down slightly the valve stem tip with a grinder and measure the clearance again.

If the clearance is larger than the specified allowance, replace the valve with a new one and adjust the clearance using some compound etc.

Note: Install the valve spring retainers after completing adjustment of the tappet clearance. Then recheck the clearance.

*Installment of spring retainers

Place the retainer, using a special tool, over the valve stem with the retainer’s notch facing towards the front.
