Parts Requiring Angular Tightening
ISome important engine parts are tightened using an angular-
tightening method rather than a torque setting method.
I If these parts are tightened using a torque setting method, dis-
persal of the tightening force (axial bolt force) will be two or
three times that of the dispersal produced by using the correct
angular-tightening method.
I Although the torque setting values (described in this manual)
are equivalent to those used when bolts and nuts are tightened
with an angular-tightening method, they should be used for
reference only.
I To assure the satisfactory maintenance of the engine, bolts and
nuts must be tightened using an angular-tightening method.
I Before tightening the bolts and nuts, ensure that the thread and
seating surfaces are clean and then coated with engine oil.
I The bolts and nuts which require the angular-tightening method
are as follows:
(1) Cylinder head bolts
(2) Connecting rod cap nuts
Liquid Gasket Application Procedure
a. Before applying liquid gasket, use a scraper to remove all
traces of old liquid gasket from mating surface and
grooves, and then completely clean any oil stains from
these portions.
b. Apply a continuous bead of liquid gasket to mating sur- faces. (Use Genuine Liquid Gasket or equivalent.)
IBe sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in)
wide (oil pan).
I Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.118 in)
wide (in areas except oil pan).
c. Apply liquid gasket to inner surface around hole perimeter. (Assembly should be done within 5 minutes after coating.)
d. Wait at least 30 minutes before refilling engine oil and engine coolant.

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.
