Straightening
1.
When performing straightening repairs with the frame on
the vehicle:
• Use spreader plates or wood blocking to distribute chain
force to avoid damage to frame box section.
• Be sure to loosen sufficient length of frame to allow
frame force points to move without causing other dam-
age.
• Restrain vehicle movement in both directions along line
of force application.
2.
Vertical bends, except at end sections, require removal of
frame rail from vehicle.
3.
Application of bulk heating to frame components is not
authorized, metal properties will be irreversibly degraded.
4.
At the conclusion of a bend repair, carefully inspect welds
in the vicinity of repair and area of force application. Any
evidence of cracking or chipping of welds must be
repaired.

Winch Troubleshooting
Winch Inoperative
1.
Check for jammed winch cable.
2.
Check winch control cable connector for corrosion or
loose connection. Clean corroded connector or secure
loose connection.
3.
Check for loose or damaged winch power cables. Using
voltmeter, connect positive meter lead to positive power
cable (red) at the winch motor, and negative meter lead to
the winch motor ground cables (black). If voltage is not
present, repair or replace winch power cables.
4.
Disconnect winch control from winch. Using an
ohmmeter, check for continuity between the common
terminal and the other two terminals on winch control
cable connector. Check for continuity one at a time, while
holding control in the OUT position and IN position. If
continuity is present in both positions, repair winch. If
continuity is not present in both positions, replace winch
control.
