Seal Lock Adhesive
CORRECT
Precoated Parts
Precoated parts are bolts and nuts, etc. Which are coated
with ? seal lock adhesive at the factory.
(a) lf a precoated part is tightened, loosened or caused to
move in any way, it must be recoated with the
specified adhesive.
(b) Recoating of Precoated Parts
(1) Clean off the old adhesive from the bolt, nut or
installation part threads.
(21 Dry with compressed air.
(3) Apply the specified seal lock adhesive to the bolt
or nut threads.
(c) Precoated parts are indicated in the component illus-
trations by the "*" symbol.
When necessary, use a sealer on gaskets to prevent leaks.
Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
Use of special service tools (SST) and special service
materials (SSM) may be required depending on the nature
of the repair. Be sure to use SST and SSM where specified
and follow the proper work procedure. A list of SST and
SSM can be found at the back of this manual.
When replacing fuses, be sure the new fuse is the correct
amperage rating. Do NoT exceed the fuse amp rating or
use one of a lower rating.
Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the proper
locations.
(a) lf the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels in order to
ensure safety.
(b) After the vehicle is jacked up, be sure to support it on
stands. lt is extremely dangerous to do any work on
the vehicle raised on a jack alone, even for a smalljob
that can be finished quickly.
12. Observe the following precautions to avoid damage the
parts:
(a) To disconnect vacuum hoses, pull on the end, not the
middle of the hose.
(b) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(c) Be careful not to drop electrical components, such as
sensors or relays. lf they are dropped on a hard floor,
they should be replaced and not reused.

EM-2 ENGINE MECHANICAL - Description
DESCRIPTION
B, 38, 1 1 B and 148 ENGINES
The B,38, 11B, and 148 engines are in-line 4-cylinder OHV 8 valve engines with a capacity of 3.O liters (B,
1181, 3.4liters (38) or 3.7 liters (148).
38 Engine (BJ)
148 Engine (BU)
For B and 38 engines, refer to the 38 (BJ) engine, and
for 1 1 B and 148 engines, refer to the 148 (BU) engine. 8S0115 SSO116

ENGINE MECHANICAL _
s (B,
The B, 38, 118 & 14B engines are in-line 4-
cylinder engines with the cylinders numbered 1-2-
3-4 from the front. The crankshaft is supported by
5 bearings inside the crankcase. These bearings
are made of aluminum alloy.
The crankshaft is integrated with 8 weights
which are cast with it for balancing. Oil holes are
made in the center of the crankshaft to supply oil to
the connecting rods, bearings, pistons and other
components.
The ignition order is 1-3-4-2. The cylinder head
is made of cast iron, with a cross flow type intake
and exhaust layout. The combustion chambers are
swirl chamber type for the B and 38 engines and
direct injection type for the 11B and 148 engines.
An intake shutter is installed in the intake
manifold to reduce intake noise.
Each intake and exhaust valve is equipped with
an inner and outer spring made of special valve
spring carbon steel, capable of following no matter
what the engine speed.
The cam shaft is driven by a timing gear. The
cam journal is supported at 5 places between the
valve lifters of each cylinder and at the front and
rear ends of the cylinder block. Lubrication of the
cam and the cam journal is performed by oil
supplied through the oiler port in each journal of
the cylinder block.
The valve lifter is turned by the roller lifter for
reduced friction and abrasion.
Adjustment of the vlave clearance is done by
means of an adjusting screw on the rocker arm.
The timing gear cover is made of aluminum
alloy. For the BU and BB series, the power steering
pump is attached to timing gear cover.
Pistons are made of highly temperature-resistant
aluminum alloy. As the 11B and 148 engines are
the direct injection type, a deep combustion
chamber has been provided. The No. 1 piston ring
groove has been strengthened using a ceramic
fiber alloy.
Piston pins are the full-floating type, with the
pins fastened to neither the connecting rods nor
the piston boss, but with a snap ring fitted to both
ends of each pin to prevent it slipping out.
The No. 1 compression ring is made of steel and
the No.2 compression ring is made of cast iron. The
oil ring is made of a combination of steel and
stainless steel. The outer diameter of each piston
ring is slightly larger than the diameter of the
piston and the flexibility of the rings allows them to
hug the cylinder walls when they are mounted on
the piston. Compression rings No.1 and No.2 work
to prevent the leakage of gas from the cylinder and
oil ring works to scrape oil off the cylinder walls to
prevent it from entering the combustion chambers.
The cylinder block is made of cast iron. lt has 4
cylinders which are approximately 2 times the
length of the piston stroke. The top of the cylinders
is closed off by the cylinder head and the lower end
of the cylinders becomes the crankcase, in which
the crankshaft is installed. ln addition, the cylinder
block contains a water jacket, through which cool-
ant is pumped to cool the cylinders.
The oil pan is bolted onto the bottom of the
cylinder block. The oil pan is an oil reservoir made
of pressed steel sheet. A dividing plate is included
inside the oil pan to keep sufficient oil in the
bottom of the pan even when the vehicle is tilted.
This dividing plate also allows the oil pump to
maintain the oil supply when the vehicle stops
suddenly and the oil forms waves.

EM-4 ENGINE MECHANICAL - Diesel Engine Diagnosis
DIESEL ENGINE DIAGNOSIS
1. GENERAL
Diesel engine problems are usually caused by the engine or fuel system. The injection pump is very
rarely the cause of fuel system problems.
Before beginning fuel system tests, first check that the engine compression, valve timing and other major
systems are within specifications.
2. PRELIMINARY CHECKS
(a) Before performing fuel system checks, insure that the engine is in good running condition. lf
necessary, first check the compression, timing and major components or systems.
(b) Check the air filter and clean or replace as necessary.
(c) Check for sufficient fuel in the tank.
(d) Check if the fuel is contaminated with gasoline or other foreign elements. Only high-quality diesel
fuel should be used.
(e) Bleed air from the system by pumping the priming pump.
(f) Check for water in the sedimenter and fuel tank, and drain as necessary.
(g) lf the engine will not crank or if it cranks slowly, troubleshoot the electrical system.
