Camshafts/Rocker Arms and

Camshaft Seals

CAUTION:

• Make sure that all rockers are in alignment with their

valves when torquing the rocker assembly bolts.

• To prevent the rocker arm assembly from coming

apart, leave the camshaft holder bolts in the holes.

• Handle the rocker arms carefully so that the oil does

not come out of the hydraulic tappets.

1. Install the camshaft and rubber cap, then install the

camshaft seal with the open side (spring) facing in.

NOTE:

• Position the camshaft with pin hole at the top.

• Do not apply oil to the camshaft holder mating

surface of the camshaft seal.

• Apply liquid gasket. Part No. 08718 - 0001 or

08718 - 0003 around the rubber cap.

5. Tighten the cylinder head bolts sequentially in 2 or

3 steps.

Specified Torque:

76 N-m (7.8 kgf-m, 56 Ibf-ft)

NOTE:

We recommend using a beam-type torque wrench.

to tighten slowly and not to overtighten.

If a bolt makes any noise while you are torquing

it, loosen the bolt and retighten it.

Before installing the cylinder head cover gasket,

thoroughly clean the seal and the groove.

When installing, make sure the head cover gasket

is seated securely in the corners of the recesses

with no gap.

Check that the mating surfaces are clean and dry

before applying liquid gasket.

Do not install the parts if five minutes or more have

elapsed since applying liquid gasket. Instead, reap-

ply liquid gasket after removing old residue.

After assembly, wait at least 30 minutes before

filling the engine with oil.
