Screw M7 bolt-1 into the threaded hole as indicated in the
figure; hold the fork shaft, knock slightly the transmission
housing with plastic hammer until the bearing comes out
and at the correct position. Screw in the bolt-2 and fasten
it with 15Nm torque. Screw in reverse gear bolt and fasten
it with 20Nm torque. Screw in the fastening bolt of fore
and rear housings and fasten it with 25Nm torque; fasten
the rear bearing baffle of input shaft with 15Nm torque.
Adjustment of gear-5 fork
Adjust the gear-5 fork by the following procedures
Notes:
Never pull out the fork shaft from gear-5 fork bush,
otherwise the fork and guide board in the housing may
deviate from their due positions and fall out, thus they
must be reinstalled.
Before mounting the shifting shaft, put transmission at
neutral position. Insert the shifting shaft and big spreader
spring, and then screw on the plug with 50Nm torque.
Right screw the fork bush until the bush comes out by
X=5mm. Pull out the shift shaft completely, left screw
it and shift to gear 5. Lift slightly the gear-5 connecting
bush to eliminate the clearance between driving
mediums.
Screw in the shifting fixing-seat assy. and fasten it with
40Nm torque.
Check the clearance between gear-5 connecting bush
and connecting tooth of gear-5 driving gear. The
theoretical value a=1mm. If necessary, screw the gear-5
fork bush to adjust this clearance to be 1mm.
Note: when measuring clearance a, move slightly the
sliding bush and fork to eliminate the free gap.
