CLUTCH INTRODUCTION

CLUTCH STRUCTURE

·As picture below, the clutch is dry diaphragm with single leaf. It consists of clutch driven

disk (2), release disk (4), intermediate disk (6), pressure plate (7) and flywheel (1).

·There are diaphragm springs in the pressure plate (7), which are fixed in the crankshaft by

intermediate disk (6) and bolt (5). Driven disk (2) is pressed on the flywheel (1) by
pressure plate (7), and bolt (8) is used to fix pressure plate (7) and flywheel (1) together;
the clutch pusher (9) is used to push separator disk (4) and then the separator disk (4) to
push the small end of diaphragm springs on pressure plate (7).

OPERATING PRINCIPLE OF CLUTCH

·As picture below, Picture a presents the connection status of clutch. When clutch pedal is

not treaded, the driven disk (3) is pressed on flywheel (2) by diaphragm spring (1). Driven
disk (3) and flywheel (2) are revolving synchronously, and the torque is transmitted to the
transmission-axle (6) by Separator disk (5) through driven disk (3).

·Picture b presents the disconnection state of clutch. When the clutch is treaded, pusher (4)

pushes separator disk (5) which presses the small end of diaphragm spring (1) to move the
big end of diaphragm spring (1) away from driven disk (3), so the pressure is disengaged
between driven disk (3) and flywheel (2) and the clearance is generated to cut off the
motive power of engine and pass the transmission.

ASSEMBLY AND ADJUSTMENT OF CLUTCH CABLE

·Put dust cap up and screw jam nut (11) and

adjustment bushing (12) to the upper end
(make the adjustment travel L minimum)
so as to facilitate the assembly of clutch
cable.

·Coat a little lubricant on the assembly

fitting surface of clutch cable.

·Put clip (1) across the guiding cylinder of

clutch pedal on the front brattice to
connect the clutch pedal. Make sure that
washer (3) and end face of guiding
cylinder of clutch pedal are spliced.

·Make butt end (18) fixed by bracket after

across the slot in release arm of
transmission and rubber cushion through
the upper face of transmission.

·After the assembly, uplift the segregation

arm of transmission by hand and adjust the
adjustment bushing (12) down at the same
time, so the 2~3mm clearance for
segregation

arm

of

transmission

is

available; then tread the clutch pedal for 10
times to ensure the fitness of assembly and
readjust

the

adjustment

bushing

to

guarantee that the 2~3mm clearance for
segregation

arm

of

transmission

is

available (Remarks：For new clutch, the
adjustment travel L of driven disk cable
shall not be less than 18mm. See Pic.2).

·Carry out the driving examination for the

whole automobile. Clutch and gear shifting
operation shall be normal.

·Screw jam nut (11) down to close with

adjustment bushing (12), and then put
down dust cover (9).
