21. INSPECT CAMSHAFT THRUST CLEARANCE
(a) Install the 2 camshafts.
(b) Using a dial indicator, measure the thrust clearance while
moving the camshaft back and forth.
Standard thrust clearance:
0.040 ± 0.095 mm (0.0016 ± 0.0037 in.)
Maximum thrust clearance: 0.110 mm (0.0043 in.)
(c) If the thrust clearance is greater than maximum, replace the cylinder head. If damages are found on the camshaft
thrust surfaces, the camshaft also has to be replaced.
22. INSPECT CAMSHAFT OIL CLEARANCE
(a) Clean the bearing caps and camshaft journals.
(b) Place the camshafts on the cylinder head.
(c) Lay a strip of Plastigage across each of the camshaft jour- nal.
(d)Install the bearing caps (See page 14±4). Torque:
No. 1 23 N m (235 kgf cm, 17 ftlbf)
No. 3 13 N m (132 kgf cm, 10 ftlbf)
NOTICE:
Do not turn the camshaft.
(e) Remove the bearing caps.
(f) Measure the plastigage at its widest point.
Standard oil clearance:
0.035 ± 0.072 mm (0.0014 ± 0.0028 in.)
Maximum oil clearance: 0.10 mm (0.0039 in.)
NOTICE:
Completely remove the Plastigage after the measuring.
If the oil clearance is greater than maximum, replace the cylin-
der head.

24. INSTALL UNION
(a) Mark the standard position away from the edge, onto the
water hose union as shown in the illustration.
(b) Apply adhesive to the water hose union hole of the cylin- der head.
Adhesive:
Part No. 08833±00070, THREE BOND 1324 or equiva-
lent.
(c) Using a press, press in a new water hose union until the standard marks come to the level of the cylinder head sur-
face.
Standard protrusion:
A 29 mm (1.14 in.)
B 66.5 mm (2.62 in.)
C 24 mm (0.95 in.)
NOTICE:
Install the water hose union within 3 minutes after ap-
plying adhesive.
Do not put into coolant within an hour after installing.
25. INSTALL VALVE GUIDE BUSH
(a) Gradually heat the cylinder head to 80 ± 100 C (176 ±
212 F).
(b) Using SST and a hammer, tap in a new guide bushing to the specified protrusion height.
SST 09201±10000, 09201±01055, 09950±70010 (09951±07100)
Protrusion height: 8.7 ± 9.1 mm (0.342 ± 0.358 in.)

26. INSTALL VALVE STEM OIL O SEAL OR RING
(a) Apply a light coat of engine oil on the valve stem oil seals.
NOTICE:
Be very careful to assemble the oil seal for intake and ex-
haust. Assembling the wrong one may cause a failure.
HINT:
The intake valve stem oil seal is gray and the exhaust valve
stem oil seal is black.
(b) Using SST, push in a new valve stem oil seal. SST 09201±41020
27. INSTALL INNER COMPRESSION SPRING
(a) Install the valve, spring seat, valve spring, and spring re- tainer.
(b) Using SST, compress the valve spring and place the 2 keepers around the valve stem.
SST 09202±70020 (09202±00010)
(c) Using a plastic hammer and the valve stem (not in use) tip wound with vinyl tape, lightly tap the valve stem tip to
ensure a proper fit.
NOTICE:
Be careful not to damage the valve stem tip.
