ENGINE MECHANICAL - Cylinder Head
E. Inspect camshaft journal oil clearance
(a) Install the camshaft bearings to the No.1 bearing cap
and No.1 journal of the cylinder head.
(See step 4 (b) on page EM-78)
(b) Clean the bearings and camshaft journals.
(c) Place the camshaft on the cylinder head.
(d) Lay a strip of Plastigage across each of the camshaft
journals.
(e) Install the bearing caps.
(See step 4 (c) to (e) on page EM-78)
Torque: 250 kg-cm (18 ft-lb, 25 N m)
HINT: Do not turn the camshaft.
(f) Remove the bearing caps.
(g) Measure the Plastigage at its widest point.
Standard oil clearance:
No.1 journal 0.022-0.074 mm
(0.0009-0.0029 in.)
Others 0.030-0.066 mm
(0.0012-0.0026 in.)
Maximum oil clearance: 0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace the
bearings or camshaft. If necessary, replace the bearing caps
and cylinder head.
(h) Completely remove the Plastigage.
F. Inspect camshaft thrust clearance
(a) Install the camshaft.
(See step 4 on page EM-78)
(b) Using a dial indicator, measure the thrust clearance
while moving the camshaft back and forth.
Standard thrust clearance: 0.10-0.20 mm
(0.0039-0.0079 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)
If the thrust clearance is greater than maximum, replace the
thrust plate. If necessary, replace the camshaft.
15. INSPECT VALVE LIFTERS AND LIFTER BORES
(a) Using a caliper gauge, measure the lifter bore diameter
of the cylinder head.
Lifter bore diameter: 40.960 — 40.980 mm
( 1 . 6 1 2 6 - 1 . 6 1 3 4 in.)
