ABSTRACT OF THE DISCLOSURE A winch transmission and control which through selective energization of separate parts of the transmission enables the winch to automatically change to a different output speed, produce a fully braked condition, or a freewheeling condition. Reversing of the direction of the drum occurs through reversing the direction of the power input motor to the transmission. A unique, single lever hand control is operatively associated with means for energizing the clutch mechanisms which control the various parts of the trans- mission as well as control the reversibility and stroke of a pump which drives the input motor. The hand control assures a proper correlation between braking and powering of the drum. Another unique feature is a combination cable guide and external structural tie bar for a hollow drum of a towing winch used on a towing vehicle for strengthening the winch drum case. Another unique feature is a technique for installing large, slow-speed ball bearing in a bearing race.
