Clutch housing assembly and planetary gear assembly tool

Abstract

A tool for installing and removing a clutch drum piston assembly from a planetary gear assembly and for installing and removing the planetary gear assembly within an automobile automatic transmission includes a sliding hammer arrangement and an adjustable spindle adapted to be used with clutch drum assemblies of various diameter central apertures. The adjustable spindle is formed form a plurality of elongated arcuate members radially disposed about a cylindrical member intermediate the ends of the arcuate members defining a fulcrum. An adjustment collar having a tapered interior surface is disposed about one end of the elongated arcuate members. As the adjustment collar is moved axially toward the other end of the assembly, the tapered inner surface causes the arcuate members to pivot radially outwardly about the fulcrum. A shaft is connected to the disk and extends outwardly from the collar. The outwardly extending portion of the shaft serves as a guide for a sliding hammer. The interior surface of the adjustment collar is provided with one or more cam followers which cooperate with cam surfaces integrally formed on the ends of the arcuate members. The cam surfaces allow the adjustment collar to be axially fixed with respect to the arcuate members.
