The tool for installation of oil seal can be used to install the three bushes. When installing the bushes,

stagger the gap on the bush and that on the clutch housing (the two gaps can not coincide), as shown in

Figure 21.

Wearing bush

Now start to install release bearing assembly and release bearing as shown in Figure 22. First, install

the two wearing bushes to their designated positions, and then put the release bearing through bush, release

return torsion spring, release fork (release fork and release bearing should be assembled properly in advance,

and then set the release bearing onto the housing) and bush in turn up to its designated position, finally,

tighten the release arm bolts (with torque as 20±2Nm). See Figure 23.

3. Assembly of transmission housing

First, use a special tool to fit oil seal of the differential to its designated position (when fitting the oil seal,

care should be taken to prevent oil leak in the future, and replacement with new oil seal is recommended),

and then respectively install oil drain channel, bush (note: the installation process for this bush is the same

as that for the bush of clutch housing above), linear bearing etc. to their designated positions. See Figure 24.

4. Assembly of gearshift mechanism assembly

Assembly of gearshift mechanism assembly is comparatively simple, which can refer to the disassembly

process of the gearshift mechanism assembly. Remember to check the amount of parts to prevent neglected

installation. Please refer to Figure 25 for tightening torque of the bolt.

5. Assembly of gearshift fork assembly

Assembly of gearshift fork assembly is comparatively simple, which can be assembled with reference to

the disassembly drawing.

6. Regulation and assembly of input shaft assembly

Place the input shaft with its end with clutch spline down, and then set the third gear needle bearing

applied with the gear oil of the same designation as that used inside the transmission assembly onto the input

shaft. Set the third gear driving gear assembly in from upside of input shaft with the end with synchronizer

cone of the gear assembly up, and then check and make sure that the gear assembly can rotate freely. Set a

3/4/5 gears synchronizer ring in from upside of input shaft with conical surface of the synchronizer ring

applied with the gear oil of the same designation as that used inside the transmission assembly, and then

check and make sure that the synchronizer ring should envelop loosely on synchronizer cone of the third

gear driving gear assembly and can rotate relative to the synchronizer cone. Press 3/4 gears synchronizer

assembly onto the input shaft with the end surface of gear hub with two oil grooves down, turn the

synchronizer ring to make its guide block completely enter the groove corresponding to the gear hub, and

then make sure that the synchronizer ring is not locked. Fit front snap ring of input shaft; when fitting, try to

use the thicker snap ring, if really unsuitable, select the snap ring of next thinner level, and then check if the

snap ring has really enter the groove with the clearance between the snap ring and the groove not exceeding

0.05mm. Set a 3/4 gears needle bearing applied with the gear oil of the same designation as that used inside

the transmission assembly onto the input shaft from upside of the input shaft. Set a 3/4/5 gears synchronizer

ring applied with the gear oil of the same designation as that used inside the transmission assembly in from

upside of the input shaft. Set the fourth gear driving gear assembly in from upside of input shaft with the end

with synchronizer cone of the gear assembly down (the guide block of 3/4 gears synchronizer ring should

completely enter the groove corresponding to the gear hub), and then make sure that the gear assembly can
