An improved tram transmission (10) for transferring power produced by a tram motor (54) to a tram crawler chain (66) more efficiently than transmission of prior art. The improved tram transmission (10) includes a motor drive shaft receptacle (12) which is dimensioned for receiving the drive shaft (56) of a tram motor (54). A plurality of cooperating pairs of gears (70) are provided to cooperate with the motor drive shaft receptacle (12) such that the power produced by the motor (54) may be transferred to the crawler chain (66). A plurality of shafts (73) are included to support the gears (70) and are held in place with ball bearings (183). The main shaft (76) carries a hub (158) which includes a plurality of sprockets (166) for engaging the crawler chain (66). A housing (18) is provided for shielding the components (12, 70, and 183) from debris and moisture and for containing lubricant (68) for the gears (70), shafts (73) and bearings (183).
