Camshaft Installation Note
Caution
•
Because there is little camshaft thrust
clearance, the camshaft must be held
horizontally while it is installed. Otherwise,
excessive force will be applied to the
thrust area, causing burr on the thrust
receiving area of the cylinder head journal.
To avoid this, the following procedure
must be observed.
1. Assemble camshaft onto the cylinder head, facing
the cam noses at No.1 and No.3 cylinders as
shown.
