ABSTRACT:
A method and apparatus for ready replacement of a noncreeper subassembly in a tractor transmission with a creeper subassembly. The method includes subassembly removal and replacement through a window. Removal is by opening the window, reaching in to move, along a subassembly main shaft, a collar which joins the main shaft to a shuttle shaft and in so doing opening a void between the shafts, and then using the void to advantage to manipulate the subassembly out the window. Replacement reverses the same steps. The collar on the creeper subassembly has means for seating a bearing.
