Title: Shaft manipulating and centering tool

Abstract: A shaft manipulating centering and assembly tool for use in a housing bore has four basic members, a manipulating member, a pressing member, a locking member and a power drive member. The manipulating member has an outer surface the radius of the bore and an inner surface that includes one section the radius of the shaft and a flat section. The pressing member has limited rotation within one end of the manipulating member and can push against the bore wall or shaft and can turn the manipulating member. The locking bar member anchors the tool on a housing stud. The drive member turns the pressing member and manipulating member and holds the locking bar in place. By placing the tool beside the shaft within the bore and turning it in a first direction, the shaft is lifted onto the manipulating member and the locking bar moves beside the housing stud. By rotating it in the opposite direction, the locking bar engages the stud and the pressing member moves the shaft to one end of the bore on the manipulating member flat section so that the shaft can be easily turned. By further rotation in the first direction the shaft is lifted by the manipulating member flat section until it falls into its arcuate section where it is centered in the bore. By centering the rear end of the shaft with a centering device, the tool can be removed and bearings inserted in the front end of the housing, after which the centering device in the rear can be removed and bearings inserted in the rear bore around the shaft rear end.
