5. Install the valve spring and the spring retainer.Place the end of the valve spring with the closely
wound coils toward the cylinder head.
6. Install the valve spring compressor attachment and the valve spring compressor. Compress the valve
spring, and install the valve cotters.
7. Remove the valve spring compressor and the valve spring compressor attachment.
8. Lightly tap the end of each valve stem two or three times with a plastic mallet (A) to ensure proper
seating of the valve and valve keepers. Tap the
valve stem only along its axis so you do not bend
the stem. 1. Reassemble the rocker arm assembly (see page
6-46).
2. Clean and dry the No. 5 rocker shaft holder mating surface.
3. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the cylinder
head mating surface of the No. 5 rocker shaft
holder. Install the component within 5 minutes of
applying the liquid gasket.
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be install within 4 minutes.
 If too much time has passed after applying the liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket.
4. Insert the bolts (A) into the rocker shaft holder, then install the rocker arm assembly (B) on the cylinder
head.
Apply liquid gasket
along the broken line.

4. Set the crankshaft to top dead center (TDC). Align
the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
5. Set the camshaft pulley to TDC (see step 2 on page 6-21).
6. Install the cylinder head on the engine block.
7. Measure the diameter of each cylinder head bolt at point A and point B.
8. If either diameter is less than 10.6 mm (0.42 in.), replace the cylinder head bolt. 9. Apply new engine oil to the threads and under the
bolt heads of all cylinder head bolts.
10. Tighten the cylinder head bolts in sequence to 39 N·m (4.0 kgf·m, 29 lbf·ft). Use a beam-type
torque wrench. When using a preset click-type
torque wrench, be sure to tighten slowly and do not
overtighten. If a bolt makes any noise while you are
torquing it, loosen the bolt and retighten it from the
first step.
11. After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown in
step 10. If you are using a new cylinder head bolt,
tighten the bolt an extra 90 °.
NOTE: Remove the cylinder head bolt if you
tightened it beyond the specified angle, and go
back to step 6 of the procedure. Do not loosen it
back to the specified angle.
