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 bolts
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.
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

EX 46.72 mm (1.8394 in)
Limit: IN 46.57 mm (1.8335 in)
EX 46.67 mm (1.8374 in)3. Cam Run-Out
1) Mount the camshaft on V-blocks.
2) Measure the cam height (H) with a micrometer.
If the measured value is less than the specified
limit, the camshaft must be replaced.
Standard: 0.02 mm (0.0008 in) or less
Limit: 0.10 mm (0.0039 in)
4. Camshaft oil clearance
1) Clean the camshaft, camshaft bracket and
camshaft carrier.
2) Put camshaft carrier on the cylinder head.
3) Put camshaft on the camshaft carrier.
4) Put plastigauge on the camshaft journal.
5) Install camshaft bracket to original position and
tighten bolts to specified torque in the numerical
order shown in the illustration.
Torque: A; 21.6 Nꞏm (2.2 kgꞏm/15.9 lb ft)
