C. If rear pump linkage assembly (item 2) needs to
be disassembled, note that rear balljoint has left
hand threads and a groove to identify it. Linkage as-
sembly components are shown in Fig. 36.
Assembly (Fig. 33)
1. If rear pump linkage assembly was disassembled,
use the following during assembly (Fig. 36):
A. If removed, thread both jam nuts onto linkage rod.
Install outer jam nut so that it is 1.510” (38.4 mm)
from end of rod. Then tighten inner jam nut against
outer jam nut and torque from 111to145in-lb(12.6
to 16.3 N- m).
B. Install springs and balljoints to the ends of the
linkage rod so that the springs are compressed to a
length of 1.000” (25.4 mm).
C. The standard balljoint center to center length of
the rear pump linkage should be 21.010” (53.4 cm)
after assembly.
2. Assemble removed transmission control compo-
nents using Figure 33 as a guide.
A. If rear pump linkage assembly (item 2 in Fig. 33)
was removed, install pump linkage so that the end
with jam nuts is orientated toward front of machine
(shown in Fig. 3 7). When securing pump linkage to
transmission traction lever ( item 21 in Fig. 33),
torque flange head screw (item 12 in Fig. 33) and
flange nut (item 1 in Fig. 33) from 15 to 19 ft- lb (21 to
25 N- m).
B. If motion control handle (item 16 in Fig. 33) was
removed from motion control (item 13), make sure
that spring washers are installed with the concave
sides facing each other as shown in Figure 35.
Torque flange nut from 10 to 16 ft- lb (14 to 21 N- m)
to secure motion control handle. After flange nut is
properly torqued, install and torque jam nut against
flange nut from 38 to 52 ft- lb (52 to 70 N- m).Hold
flange nut with wrench while torquing jam nut so that
flange nut torque does not change.
C. If motion handles (item 17) were removed, align
the ends of the handles during assembly.
3. After all transmission control components have been
installed, perform adjustments for control handle posi-
tion, neutral position, control handle dampening and
neutral lock resistance (refer to Operators Manual). Al-
so, make sure that traction interlock system correctly
prevents engine starting and operation when motion
control handles are not in the neutral locked position.
