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.

4. Tighten the bolts in two or three steps in the order

shown.

5. Apply clean engine oil to the new oil seal.
6. Push the oil seal slightly in by hand.
