NOTICE:

Remove any oil from contact surface.

Install the cylinder head within 3 minutes after apply-
ing seal packing.

After installing the cylinder head, cylinder head bolts
must be tightened within 15 minutes.

Do not start the engine within 2 hours after installing.
(b)Apply a light coat of engine oil on the threads of the cylin- der head bolts.
(c)Install bolts and plate washers to the cylinder head.
NOTICE:
Do not drop the washers into the cylinder head.
(d)Using several steps, install and tighten the 10 cylinder head bolts and plate washers with a 10 mm bi±hexagon
wrench uniformly, in the sequence shown in the illustra-
tion.

(b) Lift the cylinder head from the dowels on the cylinder
block, and place the cylinder head on wooden blocks on
a work bench.
NOTICE:
Be careful not to damage the contact surfaces of the cylin-
der head and cylinder block.
HINT:
If the cylinder head is lift off, pry between the cylinder head and
cylinder block with a screwdriver.
67. REMOVE CYLINDER HEAD GASKET
68. INSPECT CYLINDER HEAD SET BOLT
(a) Using vernier calipers, measure the tension portion diam-eter of the bolts.
Standard outside diameter:
10.75 to 11.00 mm (0.4232 to 0.4331 in.)
Minimum outside diameter: 10.40 mm (0.4094 in.)
If the diameter is less than minimum, replace the bolt.
69. INSTALL CYLINDER HEAD GASKET
(a) Measure protrusion height of the piston heads. (1) Clean the cylinder block with solvent.
(2) Set the piston to be measured to slightly beforeTDC.
(3) Place a dial indicator on the cylinder block, and cali- brate the dial indicator at 0 mm (0 in.).
HINT:

Place measuring tip of the dial indicator as shown in the
illustration.

Make sure that the measuring tip is square to the cylinder
block gasket and the piston head when measuring.
(4) Find the most overhung position of the piston head by slowly turning the crankshaft clockwise and
counterclockwise.
