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.
IAlways use a fully-charged battery to obtain specified
engine revolution.
IEngine 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.
IIf adding oil helps the compression pressure, piston rings
may be worn or damaged.
IIf pressure stays low, valve may be sticking or seating
incorrectly.
IIf 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.

a. When replacing only cylinder head gasket, install same
grade gasket as the one formerly used.
b. When replacing or repairing cylinder block, cylinder head,
piston, connecting rod and crankshaft, select gasket as
follows:
(1) Measure piston projection.
ISet each piston at its Top Dead Center. With piston held in that
position, measure its projections at two points.
ICalculate the average value of the two measurements.
IDetermine the amount of projection of the other three pistons.
(2) Select suitable cylinder head gasket which conforms to the
largest amount of projection of the four pistons.
