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.

2. Apply silicone sealant to the areas shown.

Note

•

Keep the camshaft sliding surface free of
sealant to prevent engine damage.

3. Apply engine oil to the camshaft and the cylinder

head journals.

4. Install the camshaft caps to the positions from

which they were removed.

5. Hand tighten the camshaft cap bolts marked 5, 7,

2, and 4.

6. Tighten the camshaft cap bolts a few turns in the

order shown.

7. Verify that the camshaft settles horizontally when

2 bearing cap bolts at No.3 journal are tightened.

8. Apply clean engine oil to the camshaft oil seal.
9. Push the oil seal slightly in by hand.
