Check the radial run-out of input shaft liking that shown in
figure, maximal diameter is 0.03mm.
Check the distance from back surface of synchronous loop to
gear end surface with clearance gauge, the minimal value
should be 0.8mm, if the minimal distance could not reach this
value, it is necessary to change synchronous loop.
Check the distance between gear cover and shift fork with
clearance gauge, its maximal value is 0.35mm, or it is neces-
sary to change gear cover or shift fork.
Measure the minimal diameter of abrasion surface A of input
shaft with micrometer, its value is 33.985mm, and the mini-
mal diameter of surface B is 30.985mm, if the value exceeds
this scope, it is necessary to change input shaft.

Measure axial clearance of 1 gear and 2 gear with thickness
gauge,
1 gear: 0.1—0.35mm
2 gear: 0.1—0.35mm
Measureradial clearance of 1 gear and 2 gear liking that shown
in figure, the maximal flop value is 0.056mm.
Take down tapered bearing liking that shown in figure
Note:
1. Hold the lower end of shaft to prevent it falling.
2. Clamp inner ring of bearing to make it reliable.

shown in figure.
Take down forth and fifth gear wheel with pressure machine.
Note: hold the lower end of shaft to prevent it falling.
Move first and second gear to first gear.
Disassemble third gear with pressure machine, and hold the
lower end of shaft to prevent it falling, at this time, disassemble
roller bearing, synchronous loop and second gear.
Disassemble clip spring with clamp spring pliers, and do not
hurt bearing surface of shaft.

Measure the round flop liking that shown in figure, its maxi-
mal allowed flop value is 0.03, if exceeding this value, it is
necessary to change the output shaft.
Check the axial clearance between the back surface of syn-
chronous loop and end surface of gear splines with clear-
ance gauge, its minimal value is 0.8mm, if the clearance is
less than this value, it is necessary to change the synchro-
nous loop.
Check the clearance between gear cover fork slot and fork
with clearance gauge, its maximal value is 0.35mm, if exceed-
ing this value, it is necessary to change fork.
Check the abrasion and damaged situation of output shaft,
and measure the exterior diameter of bearing platform with
micrometer, its minimal value is 33.985mm, if measured re-
sult is less than this value, it is necessary to change the out-
put shaft.
Assemble first gear and synchronous loop liking that shown
in figure.
