Installing the Carrier Frame to
the Traction Unit
1.
Fasten the angle brackets to the traction unit
frame with the six (6) 1/2"-13 x 1" (25 mm) hex
head flange bolts and flange locknuts. Position
the bottom locknuts on the outside of the angle
brackets. Torque the fasteners to 60–80 ft.-lbs
(81–109 N M) (Fig 5).
IMPORTANT: When installing the angle
brackets on traction units with hydrostatic
drive, use the 1/2"-13 x 1-1/4" hex head flange
bolts supplied with the traction unit.
2.
Attach the carrier frame to the angle brackets
with the four (4) 3/8"-16 x 1-3/4" (44 mm) hex
head bolts and locknuts. Note that the locknuts
must be on the outside of the carrier frame.
Leave the locknuts loose to allow movement
between the carrier frame and angle brackets
(Fig 5).
3.
Install the shims between the carrier frame and
angle brackets. Align the holes in the shims with
the top holes in the carrier frame and angle
brackets (Fig. 5).
4.
Install the four (4) 3/8"-16 x 7/8" (22 mm) hex
head screws with flat washers through the carrier
frame and shims, and into the threaded holes in
the top of the angle brackets. Torque the hex
head screws to 27–33 ft.-lb (37–45 N m)
(Fig. 5).
5.
Torque the four (4) 3/8"-16 x 1-3/4" (44 mm)
hex head bolts and locknuts to 27–33 ft.-lb
(37–45 N m) (Fig. 5).
