NOTE:
•During disassembly, be sure that the valve train
components are kept together and identified so that
they can be re-installed in their original locations.
•Before removing the cylinder head from the engine
and before disassembling the valve mechanism, do
a compression test and note the results.
DISASSEMBLY
1. Injector Assy
2. Glow Plug and Glow Plug Connector
3. Cylinder Head Assembly
•Refer to “Cylinder Head Gasket”
CLEAN
•Cylinder head
Carefully remove all varnish, soot and carbon on
the bare metal. Do not use a motorized wire brush
on any gasket sealing surface.
INSPECTION AND REPAIR
Make the necessary adjustments, repairs, and part
replacements if excessive wear or damage is
discovered during inspection.
1. Cylinder head gasket and mating surfaces for
leaks, corrosion and blow-by. If the gasket has
failed, determine the cause;
–Improper installation
–Loosen or warped cylinder head
–Insufficient torque on head bolts
–Warped cylinder block surface
Page 1775 of 3573

6A – 42 ENGINE MECHANICAL
2. Cylinder head for cracks, especially between valve
seats and in the exhaust ports.
3. Cylinder head deck for corrosion, sand particles in
head and porosity.
CAUTION: Do not attempt to weld the cylinder
head. Replace it.
4. Cylinder head lower surface for flatness.
Use a straight edge and a feeler gauge to measure
the cylinder head lower surface warpage.
If the measured values exceed the specified limit,
the cylinder head must be replaced.
Cylinder Head Lower Face Warpage:
Standard: 0.075 mm (0.0029 in) or less
Limit: 0.2 mm (0.0079 in)
Cylinder Head Height:
Standard: 95 mm (3.740 in)
5. Water jacket sealing plugs seating surfaces.
6. Use a straight edge and a feeler gauge to measure
the manifold cylinder head fitting face warpage.
If the measured values exceed the specified limit,
the manifold must be replaced.
Exhaust Manifold Warpage:
Standard: 0.05 mm (0.0020 in) or less
Limit: 0.20 mm (0.0079 in)
CAUTION: Do not attempt to weld the cylinder
head. Replace it.
REASSEMBLY
1. Cylinder Head
•Refer to “Cylinder Head Gasket”.
2. Glow Plug and Glow Plug Connector
•Tighten glow plugs.
Torque: 15 N·m (1.5 kg·m/11 lb ft)
