Measurement of Compression Pressure
1. Warm up engine and switch off the ignition switch.
2. Remove glow plate and glow plugs.
3. Fit compression gauge adapter to cylinder head.Compression gauge adapter:
:15-20N ×m
(1.5 - 2.0 kg-m, 11 - 14 ft-lb)
4. Ensure the ignition switch is in the ªLOCKº position and discon- nect harness connector (gray colored) from injection pump.
5. Crank engine, then read gauge indication.
I Always use a fully-charged battery to obtain specified
engine revolution.
I Engine compression measurement should be made as
quickly as possible.
Compression pressure:
Unit: kPa (bar, kg/cm2, psi)/200 rpm
Standard 2,942 (29.4, 30, 427)
Minimum 2,452 (24.5, 25, 356)
Differential limit between cylinders 294 (2.9, 3, 43)
6. If cylinder compression in one or more cylinders is low, pour a small amount of engine oil into cylinders through the glow holes
and retest compression.
I If adding oil helps the compression pressure, piston rings
may be worn or damaged.
I If pressure stays low, valve may be sticking or seating
incorrectly.
I If cylinder compression in any two adjacent cylinders is
low, and if adding oil does not help the compression, there
is leakage past the gasket surface.
Leakage past the cylinder gasket can result in oil and water
becoming mixed in the engine block cooling and lubrica-
tion chambers.

(2) Align combustion chamber knock pin with cylinder head notch,and drive in combustion chamber with a soft hammer.
3. Check amount of protrusion of combustion chamber. Protrusion:StandardLess than 0.10 mm (0.0039 in)
VALVE DIMENSIONS
Check dimensions in each valve. For dimensions, refer to SDS.
When valve head has been worn down to 0.5 mm (0.020 in) in
margin thickness, replace the valve.
Grinding allowance for valve stem tip is 0.2 mm (0.008 in) or
less.

WASTEGATE VALVE
Remove rod pin and check wastegate valve for cracks, deformation
and smooth movement. Check valve seat surface for smoothness.
Check operation of by-pass valve controller.
IMove by-pass valve to make sure that it is not sticking or
scratched.
I Measure rod end play of the by-pass valve controller.
Do not apply more than 102.6 kPa (1,026 mbar, 770 mmHg,
30.31 inHg) pressure to controller diaphragm. By-pass valve controller stroke/pressure:0.38 mm (0.015 in)/92 kPa (920 mbar, 690 mmHg,
