ADJUSTMENTS
Tappet adjustments:
Exhaust valve, .005"-.007"
Inlet valve, .003"-.005"
Note: Cylinder head nuts should be tightened
again after engine has been warmed up.
Suggestions: Check for burned or warped valves. A weak or broken valve spring causes a clicking noise
similar to a noisy tappet. When removing tappet assemblies it is advisable to leave the adjusting screws, lock
nuts and plates screwed into tappets, so that there will be no danger of tappets dropping into the interior of
the engine. Avoid lifting cylinder heads by means of water manifold—use lifting tool HE-286.
