Valve Clearance: Adjustments

NOTE: To provide a means to compensate for dimensional changes in the valve train and provide for valve adjustment, 0.060 in shorter or longer pushrods are available. If the valve clearance is less than the minimum, the 0.060 in shorter pushrod should be used. If the clearance is more than the maximum, the longer pushrod should be used. To check the valve clearance, proceed as follows:

1. Install auxiliary starter switch.

Fig. 21 Valve Adjustment Alignment Marks:

2. Mark crankshaft pulley at three locations, with No. 1 location at TDC timing mark (end of compression stroke), location No. 2 one half turn 180 degrees clockwise from TDC and No. 3 location one quarter turn clockwise 90 degrees from position No. 2, Fig. 21.

3. Turn crankshaft to number 1 location, then compress valve lifter using tappet bleed down tool No. T71P-6513-A, or equivalent, Fig. 20, and check the clearance on the following valves:
^ No. 1 Intake.
^ No. 1 Exhaust
^ No. 4 Intake.
^ No. 3 Exhaust
^ No. 8 Intake.
^ No. 7 Exhaust
4. Turn crankshaft to No. 2 location, then compress valve lifter using tool No. T71P-6513-A, or equivalent, Fig. 20, and check the clearance on the following valves:
^ No. 3 Intake.
^ No. 2 Exhaust.
^ No. 7 Intake.
^ No. 6 Exhaust.
5. Turn crankshaft to No. 3 location, then compress valve lifter using tool No. T71P-6513-A, or equivalent, Fig. 20, and check the clearance on the following valves:
^ No. 2 Intake.
^ No. 4 Exhaust.
^ No. 5 Intake.
^ No. 5 Exhaust.
^ No. 6 Intake.
^ No. 8 Exhaust.
