ENGINE OVERHAUL -Timing Belt11B-24
INSPECTION
1. TIMING BELT
Inspect each section of the belt in detail, and if any of
the following type of damage is found, replace the belt
with a new part.
(1) Hardening of backface rubber.
The backface is glossy, marks are not made even
when a fingernail is run cross it, and there is no
elasticity.
(2) Cracking of backface rubber.
(3) Cracking of canvas.
(4) Cracking at root.
(5) Cracking on side of belt.
(6) Abnormal wear on side of belt.
NOTE
The state is normal if the cutting surface is neat as
if cut with a sharp knife.
(7) Abnormal wear of teeth.
First stages: Canvas is worn (canvas fibres are raised,
rubber is removed and whitish, and canvas seams
are unclear).
Latter stages: Canvas is worn off, and rubber is
exposed (face width is narrow).
(8) Teeth are missing.
2. AUTO TENSIONER
(1) Check for oil leaks. If any leaks are found, replace.
(2) Check whether the rod end is worn or damaged,
and replace if necessary.
(3) Measure the rod protrusion length. If not at the
standard value, replace the auto tensioner.
Standard value: 12 mm

INSTALLATION SERVICE POINTS
"AAINJECTOR INSTALLATION
1. Apply a small amount of new engine oil on the O-ring.
2. While rotating the injector to the left and right, insert the
O-ring into the delivery pipe while taking care not to
damage it.
Caution
Make sure that the engine oil does not enter the
delivery pipe.
3. Confirm that the injector rotates smoothly. If it does not
rotate smoothly, the O-ring may be biting in. Remove
the injector, check the O-ring for damage, and then insert
it into the delivery pipe. Check the rotation again.
"BAFUEL PRESSURE REGULATOR INSTALLATION
1. Apply a small amount of new engine oil on the O-ring.
2. While rotating the fuel pressure regulator to the left and
right, insert the O-ring into the delivery pipe while taking
care not to damage it.
Caution
Make sure that the engine oil does not enter the
delivery pipe.
3. Confirm that the fuel pressure regulator rotates smoothly.
If it does not rotate smoothly, the O-ring may be biting
in. Remove the fuel pressure regulator, check the O-ring
for damage, and then insert it into the delivery pipe. Check
the rotation again.
"CATHROTTLE BODY GASKET INSTALLATION
Assembly so that the protrusion on the throttle body gasket
is at the position shown in the illustration.

Caution
When reusing the lash adjuster, always clean and inspect
it before installing. (Refer to the section on checking the
lash adjuster.)
INSTALLATION SERVICE POINTS
"AALASH ADJUSTER INSTALLATION
Caution
When reusing the lash adjuster, always clean and inspect
it before installing. (Refer to the section on checking the
lash adjuster.)
Assembly the lash adjuster onto the rocker arm while taking
care not to spill out diesel oil in it.
"BACAMSHAFT INSTALLATION
1. Apply engine oil on the camshaft journal and cam.
2. Install the camshaft onto the cylinder head.
Caution
Do not mistake the intake and exhaust camshafts.
There is a 4 mm width slit on the back end of the
exhaust side camshaft.
"CABEARING CAP INSTALLATION
1. Set the camshaft’s dowel pin to the approximate top.
2. The bearing caps No. 2 to 5 have the same shape. Check
the identification symbol before installing to prevent
mistaking the cap No., intake side and exhaust side.

3. Following the tightening order, tighten at 78±2N•m.
4. Completely loosen the bolts.
5. Next, following the tightening order, tighten the loosened
bolts at the torque 20±2N•m again.
6. Make paint marks on the cylinder head bolt’s head and
cylinder head.
7. Following the tightening order, tighten the cylinder head
by 90_.
8. Tighten by another 90_, and confirm that the paint mark
made on the cylinder head bolt’s head and the paint
mark on the cylinder head are positioned on the same
line.
Caution
(1) If the tightening angle is less than 90_, the
connection performance may not be attained, so
take special care to the tightening angle when
tightening.
(2) If the tightening angle is larger than the specified
value, completely loosen the bolt and start again
from step 1.
INSPECTION
1. CYLINDER HEAD
(1) Before cleaning the cylinder head, check it for water
leaks, gas leaks, damage or cracks.
(2) Completely remove the oil, water deposits, sealant
and carbon, etc. After cleaning the oil path, blow
air and confirm that there is not clogging.
(3) Using a straight edge and thickness gauge, inspect
the flatness of the bottom of the cylinder head for
strain.
If the strain exceeds the limit value, grind the end
and correct the flatness.
Standard value for lower surface strain: 0.05 mm
Limit value for lower surface strain: 0.2 mm
Grinding limit value: 0.2 mm
Cylinder head height (standard value for new part):
131.9 - 132.1 mm
Caution
The grinding limit is within 0.2 mm together with
the combined cylinder block.

"MADRAIN PLUG GASKET INSTALLATION
Replace the gasket with a new part, and install at the direction
shown in the illustration.
Caution
Incorrect installation direction will lead to oil leaks.
"NAOIL FILTER INSTALLATION
1. Clean the installation surface on the cylinder block side.
2. Apply engine oil on the O-ring for the oil filter.
3. Screw in the oil filter, and tighten approx. 3/4 of a rotation
(approx. 14±2N•m) from where the O-ring contacts
the installation surface.
INSPECTION
1. COUNTER BALANCE SHAFT
(1) Make sure that the oil hole is not clogged.
(2) Check the journal (bearing section) for seizure or
damage, and check the state of contact with the
bearings. If any faults are found, replace the counter
balance shaft, bearing or oil pump case assembly.
2. OIL COOLER BYPASS VALVE
(1) The valve must move smoothly.
(2) The L dimension must be at the standard value at
a constant temperature, constant humidity state.
Standard value: 34.5 mm
(3) The protruded dimensions must be at the standard
value after submerging into 100_C oil.
Standard value: 40 mm

"BAOIL RING INSTALLATION
1. Assemble the oil ring’s spacer into the piston ring groove.
Next, assemble the upper side rail, and then assemble
the lower side rail.
NOTE
(1) Install so that the side rail and spacer closed gaps
are at the position shown in the illustration.
(2) The following identification colours are applied on
the spacer and side rail (new parts) according to the
size.
SizeIdentification colour
S.T.D.None
0.50 mm O.S.Blue
1.00 mm O.S.Yellow
2. The side rail can be assembled easily by fitting one end
of the side rail into the piston groove and then pressing
on it with fingers as shown in the illustration.
Caution
The side rail’s closed gap could break if it is spread
open with a ring expander in the same manner as
the other piston rings.
3. After assembling into the piston, check that the side rail
rotates smoothly in either direction.
"CAPISTON RING NO. 2/PISTON RING NO. 1
INSTALLATION
Using a piston ring expander, assemble the ring with the
identification mark facing upward.
