1-21. SELF-RECOVERY WINCH.
(fig. 1-17) The self-recovery winch, where used, is mounted on the
right side chassis frame rail between the second and third axles. The winch is powered by a reversible
hydraulic motor which drives the winch drum through a planetary gearbox. It is equipped with an
automatic brake that is applied whenever the cab control lever is in the center position. All vehicles
equipped with a self-recovery winch have an operator controlled, two-position valve to activate the
reversible winch motor.
