5. See if the rocker arms of No. 1 cylinder are off the respective cam lobes (of camshaft); if so, valves (1), (2), (5) and (7) in left figure are ready for clearance checking and adjustment. Check valve lashes at valves (1), (2), (5) and (7). If the rocker arms of No. 4 cylinder are off the respective cam lobes, check valve lashes at valves (3), (4), (6) and (8).

NOTE: When checking valve clearance, insert thickness gauge between camshaft and cam-riding face of rocker arm.








6. If valve lash is out of specification, adjust it to specification by turning adjusting screw after loosening lock nut.
After adjustment, tighten lock nut to specified torque while holding adjusting screw stationary, and then make sure again that valve lash is within specification.

7. After checking and adjusting valve lashes at valves (1), (2), (5) and (7), (or (3), (4), (6) and (8)) rotate crankshaft exactly one full turn (360°) and check the same at valves (3), (4), (6) and (8) (or (1), (2), (5) and (7)). Adjust them as necessary.
8. After checking and adjusting all valves, reverse removal procedure for installation.
