ABSTRACT:
A deck winch having provision for removal of the main shaft without removal of the winch base from the deck is disclosed. The winch includes a flat keeper member disposed radially to the main shaft and which seats semi-circumferentially in a circumferential groove in a main shaft. This keeper member is normally kept in the shaft-retaining position by the pinion shaft, which is spaced from the main shaft. An opening through the keeper member is positioned over the pinion shaft just above the upper gear and below a portion of the base structure, so that when the winch drum is removed and the pinion shaft is removed following extraction of a cotter pin, the keeper member may be easily pulled out to permit removal of the main shaft.
