Lapping Valves
Reground or new valves must be lapped in, to provide
proper t. Use a hand valve grinder with a suction cup
for nal lapping. Lightly coat valve face with a ne grade
of grinding compound, then rotate valve on its seat with
grinder. Continue grinding until a smooth surface is
obtained on seat and on valve face. Thoroughly clean
cylinder head in soap and hot water to remove all traces
of grinding compound. After drying cylinder head, apply
a light coating of SAE 10 oil to prevent rusting.
Valve Stem Seals
These engines use valve stem seals on intake and
exhaust valves. Always use new seals when valves
are removed from cylinder head. Seals should also be
replaced if deteriorated or damaged in any way. Never
reuse an old seal.
