(1) Adjust voltage to specification.
(2) Check and repair coil and re-weld.
9.11 Lower battery volume, higher self-discharging
Symptoms and causes
Removing procedures
Hard engine startup
due to lower battery
volume
(1) Lower battery fluid level.
(2) Short circuit among battery plates.
(3) Plates are sulphurized.
(4) Poor contacting at circuit connections,too
much oxide on terminals. Insufficient charging.
(1) Fill in distilled water or diluted
sulfuric acid (concentration 1.1) as
specified.
(2) Remove sediments or change battery
fluid.
(3) Repeatedly recharge to remove
sulphurization.
(4) Make the connection firm, remove
oxide and apply Vaseline on terminals.
Larger battery
self-discharging
(1) Impurities in battery fluid.
(2) Short circuit on battery outside lead.
(3) Fluid overflowing from battery, connect
positive / negative poles to short circuit.
(4) Heavy shedding, damaged separator
plates and warped plates make short circuit.
(1) Add battery fluid formulated with pure
sulfuric acid and distilled water as
specified.
(2) Locate short circuit and remove.
(3) Clean battery surface and terminals
with soda water or warm water, be sure
no water is entering battery.
(4) Repair or replace battery.
● Cautions:
(1) The gas released from battery is easy to be ignited by sparks, so there should be no lighted fire presenting
during battery’s check and service. Do not let battery fluid contact skin and cloth. Wear goggles while servicing a
battery.
(2) Never short circuit two battery terminals, or it may lead to battery overheating even explosion.
(3) While dismounting or mounting electrical equipments, remove first the negative (ground) cable from
terminal. But for replacing light bulbs, cutting off relating switch would be ok.
(4) When removing a battery, remove negative cable first then positive cable. Untie battery bracket to life out
battery. Operate in reverse sequence to mount a battery.
9.12 Failure cold-start preheating system
Symptoms and causes
Removing procedures
Turn ignition key to “START”, engine stalls after flash indicator
has blinked 30 seconds at a frequency of 4 times per second.
The cause may be burnt fuse or short circuit on glow plug “P”
(normal glow plug resistance is about 2Ω), or solenoid “D” fuse
is burnt. Fuse damage or loose wire connection may also be the
causes.
Check circuit of cold start device or replace
damaged parts.

·153·
Symptoms and causes
Removing procedures
Turn ignition key to “START”, engine stalls after flash indicator
has blinked 60 seconds at a frequency of 4 times per second.
This may be caused by relay contacts inside controller that
control FGK output haves not closed due to damaged controller
or lower battery voltage (lower than 9V).
Replace controller or charge battery to
specification.
Glow plug does not ignite during normal preheating. The cause
may be blocked fuel pipe / plug fuel feeder or damaged solenoid
parts.
Check fuel pipe, replace damaged parts.
After whole preheating process has completed (ignition key on
“START”):
(1)Indicator goes off after it has blinked (quickly) for 60
seconds at a frequency of 4 times per second. This may be
caused by stuck MV output relay contacts.
(2)Indicator keeps blinking at a frequency of 4 times per
second This may be caused by stuck FCK output relay contacts.
(3)Indicator goes off after it has blinked (quickly) for 30
seconds at a frequency of 4 times per second. Coolant
temperature sensor RT is disconnected or poor contacting of RT
harness may cause this.
(1)Cut off power and replace controller.
(2)Replace controller.
(3)Replace controller.
When coolant temperature is below 15℃, turn ignition switch to
“START” will not lit indicator. Damaged indicator clip or
controller, or poor harness contacting may cause this.
Check harness first, if indicator keeps off,
replace indicator. Replace controller if
replaced indicator still does not lit.

Removing procedures
● Notes:
1. Fault- removing procedures and requirements to replacement and mounting-- temperature control
switch:
(1) Remove temperature control switch, connect its two leads to a voltmeter. Put switch in water
under heating. Switch is well if voltmeter indicates continuity at 83±2℃. ( As thermometer
error is concerned, switch is considered well even at 80~87℃.
(2) Temperature control switch case is thin, dismounting/mounting torque should not exceed 20N.m.
Otherwise it might get distort, cannot work properly.
2. In the event engine is overheated and clutch is failure while no spare parts at hand, you can set
clutching clearance to zero and fix it via 3 adjusting bolts on fan retaining plate. Let fan run
synchronizing with pulley. Bring the problem to service station quickly.

10.1.2 Structure Overview
Clutch connects engine and transmission, it transmits and cuts off power connection between these two. It is
mainly used to start up vehicle, help gear-shifting and avoid overload on transmission line. BJ6536 series light
buss adopt diaphragm spring clutch. The clutch transfers engine power through frictions at drive and driven parts,
and cuts off power with release mechanism. The clutch is operated by clutch operating mechanism. The operation
mechanism has the characteristics of low friction resistance, high transmitting efficiency and smooth-clutching.
The clutch mainly consists of clutch pedal, master cylinder, slave cylinder, booster and oil pipe.

Diaphragm spring clutch is a kind of advanced clutch, composed by pressure plate and cover assembly (24),
driven plate assembly (9) and release mechanism. By using a disc diaphragm spring (32), clutch rear disc and
cover assembly is mounted on clutch cover (30) by attaching its big end with nine rivets (31). (Its small end

contacts release bearing). A 2-step torsion damper and an auto compensative damper are mounted on driven plate.
A corrugated spring leaf (15) is mounted on front damping disc (16), two friction plates (11) is riveted on both
sides of corrugated spring leaf. Clutch disc hub (19) (with involutes spline) mounts on transmission input shaft.
The clutch driven disc assembly that slides on input shaft spline
is pressed in between flywheel and clutch
pressure disc (26). The friction force made by pressure disc transmits engine power to transmission via FR/RR
damping discs (16, 22) and through damping spring (17) / clutch disc hub.
Clutch pressure disc assembly releases away from driven plate assembly by means of releasing mechanism.
When clutch pedal is depressed, the force presses onto small end of diaphragm spring via release fork (8) through
release bearing assembly (5), thus detaches the clutch; while pedal is released, pressure disc assembly, by using
the returning force of diaphragm spring, presses on driven plate assembly to engage the clutch.
10.1.3 Check and Repair
Check each part after clutch and its operating mechanism have been removed from vehicle. Carry out
necessary maintenance and repair.
1. Check and repair -- clutch assembly
(1) Clutch driven plate assembly
①Wear on friction plate. Measure 2 rivets’ depth on driven plate (from friction plate surface to rivet head, “t”
in figure 10-1-5). If wear amount is equal or less than limit (table 10-1-1), operator should replace driven plate
assembly or fix friction plate again with rivets. Remount rivet if it is loosening. Replace two friction plates at the
same time.
Figure 10-1-5 Measure rivet depth Figure 10-1-6 Axial runout check -clutch driven plate
②Check axial runout of clutch driven plate. Measure at the spot 2.5mm from driven plate edge (figure

3. Before mounting clutch assembly on engine, clean flywheel friction face, there should be no oil dirt on
fitting surface of clutch friction plate. Meanwhile, apply a thin layer of lubricant oil on fitting surfaces of release
bearing sleeve, release fork, ball support of release fork and ball nut of push rod.
4. When to reassemble clutch, operator should first mount adjusted clutch driven plate assembly and then
cover assembly on flywheel face (be sure to set the short end of clutch plate hub in driven plate assembly to the
front). In order to make these two assemblies and flywheel concentric, one should insert a piece of spline
bar (may
use transmission input shaft as a tool) into flywheel pilot bearing to locate driven plate assembly, and put pressure
plate and cover assembly in place by flywheel locating pin. Fix them with bolts
5. Reassembe and adjust of clutch controls
Reassembly:
(1) Reassemble and check master cylinder. Thoroughly clean parts before reassembly, and bath sealing
cups and rings in brake fluid. Be sure not to block oil holes on master cylinder inner wall and piston.
① Reassembly of master cylinder. Proceed in reverse order to disassembling.
② Check after reassembly.
▲ Piston cup of master cylinder should seal well. There should be no brake fluid weeping on it when
piston goes back and forth.
▲ Perform sealing test under an oil pressure of 13Mpa. Ensure no leakage occurs in 5 seconds.
(2) Reassemble and check slave cylinder. Thoroughly clean parts before reassembly, and bath sealing ring
and cup in brake fluid.
① Reassemble slave cylinder. Proceed in reverse order to disassembly.
② Check after reassembly.
▲ After reassembling, devices should operate freely without any restriction or grabbing.
▲ Perform sealing test under an fluid pressure of 13Mpa. Ensure no leakage occurs in 5 seconds.
(3) Reassemble clutch pipeline
① Proceed in reverse order to disassembly.
② During reassembly, keep oil pipe and connectors clean, clamp pipes and fasten the connectors. There
should be no restriction in pipeline or weeping at connectors.
(4) Reassemble clutch pedal mechanism
① To make sure all fitting surfaces of all pins, shaft and pinhole are clean. Apply a layer of thin lubrication
grease on them.
② Proceed in reverse order to disassembly.
③ After reassembly, the rotating components should be connected firmly and can move freely.
④ Install the reassembled clutch pedal mechanism onto the instrument panel and cabine floor and fix it
with connecting bolts.
Adjustment:
① Clutch pedal free travel. Free travel is the joint results made by the distance (i.e. release clearance)
between diaphragm spring release finger (or lever) end and release bearing, as well as distance between release
master cylinder pushing rod and piston. Adjust pedal free travel is in fact to adjust these two distances. Adjustment
should be made according to requirements.
a. Clutch release clearance adjustment. Change the length of slave cylinder push rod to adjust clearance.
Remove return spring between release fork and clutch housing, and loosen slave cylinder push rod locking
nuts. Turn push rod clockwise to attach ball nut with release fork, and turn ball nut backward 1-1.5 turns. Fasten
push rod locking nut, install release fork return spring. The clearance from release bearing side to diaphragm
spring release finger tip at this moment is 1.5~2.mm.
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Chapter 10 Chassis Structure and Service
·161·
b. Adjust clearance between master cylinder pushing rod and piston. Loosen locking nut on master cylinder
pusing rod, turn pushing rod counter clockwise till it touchs piston, turn pushing rod clockwise 3/4 turn, and then
fasten locking nut on pushing rod. The clearance should be 1mm.
② Clutch pedal height adjustment. While pedal has proper free travel, its high-low adjustment is made by
means of limiting screw. Method is to loosen locking nut on screw that mounted on pedal’s bracket, turn screw
clockwise. Pedal height increases as screw tread grows and lowers as tread diminishes. Keep adjusting till pedal’s
center face is 170±3mm from cab floor. Then tighten locking nut.
③ Bleed clutch pipeline system. In order to obtain normal operation for clutch hydraulic pressure
operating system, there should be no air in system fluid. To bleed the system needs two persons: one depresses
clutch pedal in the cab while the other peforms venting at slave cylinder. The bleeding procedures as follows:
a. Remove vent plug and hook up a plastic hose, place other end of hose in a see-through cup of suitable
size;
b. Fill up the cup with brake fluid. Be sure to keep adding fluid to the cup as bleeding is in progress to
maintain at least 2/3 cup of fluid all the time.
c. Unscrew vent plug for 1/2 turn, depress-release pedal many times to flood release master cylinder,
pipelines and slave cylinder;
d. Loosen vent plug, drain out fluid with air;.
e. Pedal moves downward while air fluid is being discharged. Fasten plug immediately at the moment pedal
almost lowers to its extreme position.
f. Repeat procedure “e” till there is no sign of bubbles in fluid. Then fasten vent screw plug finally, remove
hose and install screw cap.
10.1.5 Typical Faults and Elimination
1. Incomplete clutch release (see table 10-1-5).
Clutch can not cut off engine power output while pedal is depressed to floor, clutch then keeps running by
being dragged by engine. Incomplete release may lead to gear shock and shift difficulty.

2. Clutch skidding ( see table 10-1-6).
Clutch driven plate skids when clutch pressure plate cannot press driven friction plate tightly on flywheel
surface. Depress acceleration pedal under heavy load will only make engine roaming rather than speeding up.
Minor slippery is hard to be noticed, but high temperature due to friction will burn out friction plates.

10.2.2 Structure Overview
Vehicle operates differently in different situations, such as it works during start-up, accelerating, decelerating,
driving at low/high speed, driving uphill, backing up, parking etc. These need vehicle’s traction and speed to be
changed in a larger range. But torque/speed output from current vehicle engine is too limited to meet this demand.
To compensate this, vehicle powertrain employs transmission. Transmission is used to change drive ratio to make
vehicle maneuvers like backward driving and power cut-off possible.
5RYA4 transmission is a three-shaft gear type with 5 forward gears and 1 reverse gear. It is connected to
clutch housing with bolts.
