b. Use special tools to install the guide bearing
Remarks: Install the guide bearing into the flywheel, make
sure that the bearing can rotate well.
6. Check to see whether there is wearing of the diaphragm spring
Use caliper to check the wearing depth and width of the diaphragm
spring
Limit value: maximum depth 0.6mm
Maximum width 5.0mm
7. Check the throwout bearing
Rotate the bearing with hand along the axis direction.
If the bearing can not rotate or the resistance is too large, it is necessary
to replace the throwout bearing.
Remarks: The bearing is permanent lubricated, so cleaning
and lubricating is unnecessary.

2.Installtion of clutch cover
a. Align the matching mark of clutch shell with that of flywheel .
b. Tighten the bolt evenly. Exert force along the edge of the clutch
cover repeatedly until binding tightly. Tighten the bolt.
Tightening force: 19N
m
Remarks: First tighten the upper most bolt of the 3 bolts
near thelocation pin.
3. Check the end surface runout of diaphragm spring clutch finger.
Use the special tools to check the alignment of diaphragm spring.
Maximum displacement: 0.5mm
If the displacement is greater than the specified value, use the special
tools to adjust the face runout amount of the diaphragm spring clutch
finger.

2. Operation of 4WD
The operating auxiliary steering column can be shifted to 4WD status.
For position of auxiliary steering column and corresponding operating
condition refer to table.
3. Caution for operation:
a. Do not use 4WD in good surface, otherwise the tyre and components
of drive system will be damaged easily and increase the consumption
of fuel, and cause the noise of drive system.
b. Please run in 1st-Gear under “4L” gear position when run in very
low speed in field.
Operating instruction of transmission SC5M4D-C
1.The schematic diagram of transmission operating gear position
is on the handle of steering column.
During the process after vehicle is started and in traveling, it must
step the clutch pedal to bottom before the shifting. If need shift from
5
th-Gear to reverse-Gear, it should move the shifting bar to the neutral
position of 3rd/4th-Gear. Shift to R-Gear after stop the vehicle stably,
otherwise, it can not shift.
During the traveling process. It should always pay attention to the
shifting to make the vehicle matches to the speed of engine. The
correct shifting can improve the economical efficiency and prolong
the service life of engine. Do not shift from high-Gear to low-Gear on
the condition that the pointer of tachometer may enter into red area,
otherwise, the engine will be damaged.
Warning: Do not shift to reverse-Gear when the vehicle moves
forwardly, otherwise the transmission will be damaged.

2H 2WD Use this gear position when run in the general railway and high speed highway.
4H High speed 4WD Use this gear position when run in the deep snowland, sand ground or uneven road
in normal speed.
N Neutral gear When use the gear position during using of winch, it could not drive the vehicle.
4L Low speed 4WD Use this gear-position when run in uneven road such as mud land or climbing or
downward （especially when need increas e the power）.
