88
In the fork box (7) (see Figure “Gearbox
(24F+12R)”), the three dogs, fork (8),
ball-point lock (13) and parts of the inter-
lock mechanism for preventing the si-
multaneous engagement of two gears
are installed. The fork box is fastened to
the gearbox housing (1).
A shaft (9) with attached lever (15) and
bushing (12) is installed in the cover (13)
supports and the housing (6) (see Fig-
ure “Gearshift Mechanism”); the two
bushings (18) and spring (10) are
mounted between the check rings (19).
The bushings rest against the screw
(17) and the housing (6) end-face with
their ends. This mechanism serves for
positioning the gearshift lever to its neu-
tral position. The shaft (9) is connected
with the fork (1), to which the gearshift
lever is attached, by means of the dogs
(5) and (7), and lever (20). The fork (1)
is installed in the housing (6) through a
sphere (3); it is supported by spring (4).
The Range-Selector Mechanism is
mounted in the gearbox housing (1) (see
Figure “Gearbox (24F+12R)”) and in the
gearshift mechanism cover (14).
The fork (37) for shifting the toothed
coupling (36), fork for shifting the
toothed coupling (6) (see Figure “Shaft
of reduced gears and reverse”) and fork
(18) for shifting the synchronizer (26)
(see Figure “Gearbox (24F+12R)”) are
mounted on the dogs in the housing (1).
The dogs are fixed in the housing with
ball-point locks.
The shaft (9) with the levers (10) keyed
thereon is installed in the supports of the
cover (12) and housing (18) of the con-
trol mechanism (see Figure below). The
shaft (9) is fixed with a ball-point lock
(14) and connected with the fork (1), on
which the range-shift lever is fitted,
through the dogs (5) and (7) and lever
(6). The fork (1) is installed in the hous-
ing (18) in sphere (3) and supported by
spring (4).
