Guidelines for replacement

In normal conditions, unevenness may occur on the
surface of engine camshaft lobes. This does not mean
that the camshaft has to be changed. These marks do
not have any negative influence on either engine per-
formance or the durability of the engine and its com-
ponents.
Examples of acceptable wear and unacceptable wear
are shown below.

Unacceptable wear

NOTICE! The camshaft and associated rocker arms
must be changed.
