ABSTRACT:
An assembly method and tool is provided for installing a front driven gear (18) in a torpedo housing bore (24) in the lower gearcase (12) of a marine drive, without hammer blow impacting of the gear. An axial shaft (60) has a front end (62) inserted into the gear and an annular shoulder (66) for press-fitting the gear into the reduced diameter front portion (28) of the torpedo housing bore (24). A front aligner (68) is provided by an annular disc (69) having an outer circumference (70) loosley engaging the torpedo housing bore (24) and having a central opening (72) axially sliding over the axial shaft (60). A rear shaft aligner (76) has a threaded outer circumference (80) threadingly engaging a rear threaded portion (26) of the torpedo housing bore (24), and having a central axial opening (82) axially sliding over the rear end (64) of the axial shaft. The central opening (82) of the rear aligner (76) is extended axially at a stem (84) which has a rear end (86) which is internally threaded (88) and receives a threaded bolt (90) which is turned to engage the rear end (64) of the axial shaft and drive the latter axially forwardly such that its annular shoulder (66) pushes the gear (18) axially forwardly to press-fit the latter into the noted reduced diameter front portion (28) of the torpedo housing bore (24).
