To detach the co ve r of the main drive casing from
1he hub of the
driven gear, insert the rear wheel axle
into
the hub, holding up the driven gear with one hand,
and, by lightly tapping the axle end, knock the cover
out of ·the bearing pressed into the hub. The bearing is
pressed out through ~ hree holes in the hub.
After unscrewi
ng the nut securing the dri vi ng gear
bearing (left-hand thr ea d), 1he : latter is knocked out
through a special slot in the casing.
When
in sta lling the driven gear and hub assembly,
the needJ·e rollers (45 pes) mu sl~ be lubricated with
consistent
greas e. (to keep them from falling out). Ta -
ke care not to damage the casing gland and not to J. et
spring jump off the latter.
It is good practice to use a special mandrel for thi s
purpose.
Dismantling !llnd Assembling the Universal Joint

unscrew the casing (left- hand tthread) , holding back
the nut. Uncotter the wedge bolt, unscrew the nut;
us ing a soft drift, knock out the wedge bolt, .remove the
universa .] joint from the shank of the driving bevel gear.
2. Take off the four lock rings of the un i versal joint
bearings. Place the propeller shaft fork on a support
and partially press out one of the bearings through the
cross and the opposite bearing. Grip the protruding
part of the bearing in a vice and extract it from the
fork. Turn the unive rsal joint, press out, through the
universal
joint cross, and then extract the second bea-
ring.
Remove the
band s and seali ng rubber rings from
the cross
pins and take down the propeller shaft fork
from
the universal joint cross.
3 Pre ss out the r ema ining two b ea rings in the same
manner and detach the uni versal joint cross from the
se cond fork.
4.
When assembli ng the universal joint, install the
bearings and packing parts in pairs, one after another,
on the opposite
pins of the cross, af ter first mounting
the cross with its pins to be inserted into the fork.
