Adjusting Valve Tappets

Adjusting Valve Tappets (O.H.V. Engine)

To get the maximum power and best all-around performace from an engine, keep valve tappets properly adjusted. They must be adjusted after grinding valves, and should be inspected and, if necessary, adjusted about every 1000 to 1500 miles thereafter.

The need of attention to tappet adjustment is indicated by excessive clicking and noise that develops with too much overhead rocker arm play, or in other words, too much clearance between valve rocker arms and ends of valve stems.

Engine must be cold.
