ENGINE MECHANICAL
DESCRIPTION
The 1 KZ-T engine is a 3 .01- OHC turbo diesel engine .

OPERATION
 EG-3
ENGINE - ENGINE MECHANICAL

Aluminum alloy is used for the cylinder head and resin for the cylinder head cover to reduce
weight . The camshaft is belt driven and its serviceability has been increased by driving it with the
injection pump gear . The belt tensioner is a hydraulic type to maintain appropriate tension .

The cylinder block has a balance shaft built into it to reduce engine vibration . For the idle gear
between the crankshaft gear and injection pump gear a scissors type gear is used to reduce gear
grinding noise . The crankshaft has a streamlined counterweight to reduce oil friction at high
engine speeds .

A cooling channel has been provided in the piston head to reduce heat transmission to the top
ring groove . To improve the durability of the top ring, FRM (Fiber Reinforced Metal) is embedded
into it . Also, the groove has been positioned closer to the upper surface of the piston to reduce
the volume of the piston chamber . The top of the piston is alumite-coated for greater heat
resistance .

TROUBLESHOOTING
EC31F-01

Diesel Engine Daignosis

GENERAL
1. Diesel engine problems are usually caused by the engine or fuel system . The injection pump is
very rarely the cause of fuel system problems .
2. Before beginning fues system tests, first check that the engine compression, valve timing and
other major systems are within specifications .
PRELIMINARY CHECKS
1 . Before performing fuel system checks, ensure that the engine is in good running condition . If
necessary, first check the compression, timing and major components or systems .
2. Check the air filter, and clean or replace it if necessary .
3. Check that there is sufficient fuel in the tank .
4. Check if the fuel is contaminated with gasoline or other foreign elements . Only good-quality
diesel fuel should be used .
5. Bleed air from the system by pumping the priming .
6. Check for water in the fuel filter and fuel tank, and drain as necessary .
7. If the engine will not crank or if it cranks slowly, first troubleshoot the electrical system .
 EG-9
ENGINE - ENGINE MECHANICAL

PRECAUTION :
1 . The basic troubleshooting procedures for the diesel engine (valve clearance . compression, bear-

ings, valves, pistons, etc .) are the same checks you would make for gasoline engine .

2 . Repair of the injection pump requires considerable skill and use of a special test bench .

ENGINE COOLANT INSPECTION

1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
"LOW" and "FULL" lines .
If low, check for leaks and add engine coolant up to
the "FULL" line .

2. CHECK ENGINE COOLANT QUALITY

(a) Remove the radiator cap .
CAUTION : To avoid the danger of being burned, do not
remove the radiator cap while the engine and radiator are
still hot, as fluid and steam can be blown out under
pressure .
(b) There should not be any excessive deposits of rust or
scale around the radiator cap or radiator filler hole,
and the coolant should be free from oil .
If excessively dirty, replace the coolant .
(c) Reinstall the radiator cap .

EG-16
ENGINE - ENGINE MECHANICAL

(d) Remove excess water by shaking the filter element or

blowing with compressed air.
NOTICE : Do not beat or drop filter element .
(e) Wipe off dust on the air cleaner case interior .

ALTERNATOR DRIVE BELT INSPECTION

INSPECT DRIVE BELT

(a) Visually check the belt for cracks, oiliness or wear .
Check that the belt does not touch the bottom of the
pulley groove.
If one belt has any of the above defects, replace both
belts.

(b) Check the drive belt deflection by pressing on the belt

at the points indicated in the illustration with 98 N (10
kgf, 22 lbf) of pressure .
Deflection :
New belt
6 - 8 mm (0 .24 - 0.31 in .)
Used belt
8 - 12 mm (0 .31 - 0 .47 in .)

If the deflection is not as specified, adjust it .

Reference
Using SST, check the drive belt tension .
SST A 09216-00020
SST B 09216-00030
Drive belt tension :
New belt
38 - 62 kgf
Used belt
20 - 40 kgf


ENGINE - ENGINE MECHANICAL EG-17

HINT:
• "New belt" refers to a belt which has been used
less than 5 minutes on a running engine .
• "Used belt" refers to a belt which has been used
on a running engine for 5 minutes or more .
• After installing a new belt, run the engine for
about 5 minutes and recheck the belt deflection
or belt tension .

E0340-01

GLOW PLUGS INSPECTION

NOTICE : When checking the resistance of the glow
plugs, do it with the engine installed . Keep removal and
installation of the glow plugs to a minimum .

INSPECT GLOW PLUGS (See page ST-33)

Using an ohmmeter, that there is continuity between
the glow plug terminal and ground .
Resistance (Cold) :
Approx . 0.65 Q
If the resistance exceeds 1 .0 0, replace the glow plug .

Ct7' 1 8
ENGINE - ENGINE MECHANICAL

(d) Disconnect the 2 PCV hoses .

(e) Use pliers to . pinch the ends of the clamp togetho
until the lock plate engages the catch .
Make sure the lock plate and catch are engaged si
curely .
(f) Remove the intake pipe and gasket .

2. REMOVE CYLINDER HEAD COVER

Remove the 10 bolts, 2 nuts, cylinder head cover an
gasket .

3. SET NO .4 CYLINDER TO TDC/COMPRESSION

groove with the timing pointer .
(b) Check that the valve lifters on the No .4 cylinder ar
loose and valve lifters on the No .1 cylinder are tight
If not, turn the crankshaft one revolution (360 0 ) an
align the mark as above .

4. ADJUST VALVE CLEARANCE

(a) Check only the valves indicated in the illustration .
• Using a thickness gauge, measure the clearanc
between the valve lifter and camshaft .
• Record the out - of - specification valve cleat
ance measurements . They will be used later t
determine the required replacement adjustirr
shim .
Valve clearance (Cold) :
Intake
0 .20 - 0 .30 mm (0 .008 - 0 .012 in .)
Exhaust
0 .25 - 0 .35 mm (0 .010 - 0 .014 in .)

align the mark as above (See procedure step 4) .


EG-19 ,
ENGINE - ENGINE MECHANICAL

(c) Check only the valves indicated as shown . Measure

the valve clearance . (See procedure in step (a))

(d) Remove the adjusting shim .

• Turn the crankshaft to position the cam lob of the
camshaft on the adjusting valve upward .
• Using SST, press down the valve lifter.
SST 09 248 - 64010
HINT : Before pressing down the valve lifter, position the
notch on the exhaust manifold side .

• Remove the adjusting shim with small screwdriv-

er and magnetic finger .

(e) Determine the replacement adjusting shim size by

using following the formula or charts :
• Using a micrometer, measure the thickness of
the shim which was removed .
• Calculate the thickness of the new shim so the
valve clearance comes within specified value .
T Thickness of removed shim
A Measured valve clearance
N Thickness of new shim
Intake :
• = T + (A - 0 .25 mm (0 .010 in .))
Exhaust :--
• =T+(A-0 .30 mm (0 .012 in .))
• Select a new shim with a thickness as close as
possible to the calculated values .
HINT : Shims are available in 17 sized in increments of
0 .050 mm (0 .0020 in .), from 2 .500 mm (0 .0984 in .) to
3 .300 mm (0 .1299 in .) .

(c) While cranking the engine, measure the compression

pressure .
HINT : Always use a fully charged battery to obtain
engine revolution of 250 rpm or more .
(d) Repeat steps (a) through (c) for each cylinder .
NOTICE : This measurement must be done in as short a
time as possible .


EG-30
ENGINE - ENGINE MECHANICAL

Compression pressure :
3,040 kPa (31 .0 kgf/cm', 441 psi) or more
Minimum pressure :
1,961 kPa (20 .0 kgf/cm', 284 psi)
Difference between each cylinder :
490 kPa (5 .0 kgf/cm', 71 psi) or less
(e) If the cylinder compression in one or more cylinders is
low, pour a small amount of engine oil into the cylin-
der through the injection nozzle hole and repeat steps
(a) through (c) for the cylinder with low compression .
• If adding oil helps the compression, chances are
that the piston rings and/or cylinder bore are
worn or damaged .
• If pressure stays low, a valve may be sticking or
seating improperly, or there may be leakage past
the gasket .

removing the mounting bolt of the camshaft timing
pulley.
If there are any defects as shown in the illustration,
check the following points :
(a) Premature parting
• Check the proper installation .
• Check the timing cover gasket for damage and
proper installation .

(b) If the belt teeth are cracked or damaged, check to see

if either camshaft or water pump is locked .

check to see if there are nicks on the side of the idler
pulley lock .
 EG-35
ENGINE - ENGINE MECHANICAL

(d) If there is wear or damage on only one side of the belt,

check the belt guide and the alignment of each pulley.

EM3340

rod strongly against the floor or wall to check that it
doesn't move .
If the push rod moves, replace the tensioner .
