REPAIR TRANSMISSION MECHANISM AND ITS MANAGEMENT.
Disassembly of the gearbox to produce a special stand.
The stand is an angular plate (Fig. 76), set
on the table. It has several openings: hole 2
shaft with the bearing assembly, a hole 4 to the axis of the block
gears, intermediate shaft and a hole 3 to the guide
rod forks, gearbox assembly with extension and lateral
Cover, set on a stand, to fix the holes in the legs
Blow by two studs 5 and press the nuts to the plate 6. You can
greatly facilitate the work of dismantling the gearbox,
Several complicating the design of the stand. To do this, the vertical
shelf gon set the turntable, which gives
opportunity to rotate about the longitudinal transmission
axis, so that all work can be done from the top.
In the absence of the stand you can disassemble the gearbox,
fixing it in the grip of a right foot sump. At the same time on the lips
vices should be worn soft-tighten the vise nakladki.

3.Snimite with fork shaft reverse gear is engaged.
4.Postavte in neutral gear lever.
In this position, he should smoothly move along
5.Otvernite bolts crankcase side cover (with the mechanism
shift in the collection) and remove the cover. To cover this
shifted to a long, long shaft

Take a hollow mandrel and fully enter it into the axial hole
In the process, be careful not to apply the mandrel
