Valve Clearance: Adjustments

NOTE: Correct valve clearance is 0.09-0.19 in. A .060 inch longer or a .060 inch shorter pushrod is available to compensate for dimensional changes in the valve train. If clearance is less than specified, the .060 inch shorter pushrod should be used. If clearance is more than the maximum specified, the .060 inch longer pushrod should be used.

Fig. 5 Compressing Lifter To Check Valve Clearance:

1. Using an auxiliary starter switch, rotate crankshaft until No. 1 cylinder is at TDC compression stroke. Compress valve lifter using tool T82C-6500-A or equivalent. At this point, the following valves can be checked: intake Nos. 1, 3 and 6, exhaust Nos. 1, 2 and 4.
2. After clearance on these valves has been checked, rotate crankshaft until No. 5 cylinder is at TDC compression stroke (1 revolution of crankshaft), and then compress valve lifter and check the following valves: intake Nos. 2, 4 and 5. exhaust Nos. 3, 5 and 6.
