ASSEMBLY
CAUTION
Make sure all lapping compound is removed from cylin-
der head and valves after lapping is completed. If lapping

nents or engine oil, excessive engine wear and damage
may result.

keeper groove when installing valve stem seal. If the
seal is installed without using the protective sleeve,
the seal will be damaged.
