Inspection

NOTE:

Do not rotate the camshaft during inspection.

Remove the rocker arms and rocker shafts.

1. Put the camshaft and the camshaft holders on the

cylinder head, then tighten the bolts to the specified

torque.

Specified torque:

8 mm bolts: 22 N-m (2.2 kgf-m, 16 Ibf-ft)

6 mm bolts: 12 N-m (1.2 kgf-m, 8.7 Ibf-ft)

Hydraulic Tappets

Valve Installation

When installing valves in the cylinder head, coat the

valve stems with oil before inserting them into the valve

guides. Make sure the valves move up and down

smoothly.

When the valves and springs are in place, lightly tap the

end of each valve stem two or three times with a plastic

mallet to ensure proper seating of the valve and valve

keepers.

NOTE:

Make sure that the valve keepers are properly posi-

tioned on the valve stem.

Tap the valve stem only along its axis so you do not

bend the stem.

VALVE STEM ENDS
1. Fill a container with 10W - 30 engine oil and place

the hydraulic tappet in it. Press down on the check

ball with a thin wire. Bleed the tappet of air by

pumping the plunger slowly until no bubbles come

out of the hydraulic tappet.

Camshafts/Rocker Arms and Camshaft Seals

Installation

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.

2.
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 around the rubber cap.

RUBBER CAP

Replace if there was

oil leakage.

CAMSHAFT

OIL SEAL

Replace.

Seal housing surface should be dry.

Apply a light coat of oil to camshaft

and inner lip of seal.

Engine No. 1300001~1309262 (U.S.A.), 1700001~

1700751 (Canada):

Apply liquid gasket to the head mating surfaces of

the No. 1 and the No. 7 camshaft holders.

Engine No. 1309263~, 2300001 ~, 3300001~ (U.S.A.),

1700752~, 2700001 ~, 3700001~ (Canada):

Apply liquid gasket to the head mating surfaces of

the No. 1 and the No. 5 camshaft holders.

— Apply liquid gasket to the shaded areas.
3. Tighten each bolt two turns at a time in the sequence

shown below to ensure that the rockers do not bind

on the valves.

Specified torque:

8 mm bolts: 22 N-m (2.2 kgf-m, 16 Ibf-ft)

6 mm bolts: 12 N-m (1.2 kgf-m, 8.7 Ibf-ft)

Cylinder Heads

Installation (cont'd)

6. Install the head cover gasket in the groove of the

cylinder head cover. Seat the recesses for the cam-

shaft first, then work it into the groove around the

outside edges.

NOTE:

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.

HEAD COVER

Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

Use liquid gasket, Part No. 08718 - 0001 or 08718

-003.

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.

Apply liquid gasket to

the shaded areas.
8.
When installing the cylinder head cover, hold the

head cover gasket in the groove by placing your fin-

gers on the camshaft contacting surfaces (top of the

semicircles).

Once the cylinder head cover is on the cylinder head,

slide the cover slightly back and forth to seat the

head cover gasket.

NOTE:

Before installing the cylinder head cover, clean

the cylinder head contacting surfaces with a

shop towel.

Do not touch the parts where liquid gasket was

applied.

Replace the washer when damaged or deterio-

rated.

9. Tighten the nuts in two or three steps. In the final step,

tighten all nuts, in sequence, to 12 N-m (1.2 kgf-m,

Removal (cont'd)

5. Remove the bearing from the cap. Keep all caps/bear-

ings in order.

6. Remove the upper bearing halves from the connect-

ing rods and set them aside with their respective caps.

7. Reinstall the cap on the rod after removing each

piston/connecting rod assembly.

8. To avoid mixup on reassembly, mark each piston/con-

necting rod assembly with its cylinder number.

NOTE: The existing number on the connecting rod

does not indicate its position in the engine, it indicates

the rod bore size.

9. Remove the bearing cap bolts and bearing cap side

bolts, then remove the bearing caps.
