  • Patent number: 10245654
    Abstract: A clutch brake cutter for removing a disk-shaped clutch brake from off an input shaft that couples a truck engine to a transmission includes one or more cutting tools and employs a method of clamping and axially compressing a solid or multilayer clutch brake during the cutting operation. In some examples, the clutch brake cutter first guides a drill bit radially from an outer peripheral edge to an inner peripheral edge of the clutch brake. The resulting hole has a diameter that is less than the disk thickness of the clutch brake. Next, the clutch brake cutter guides a chisel lengthwise through the predrilled hole to split the hole open. The drilling and chiseling operation is repeated at an opposite location on the clutch brake to separate the clutch into at least two pieces that can be readily removed from the input shaft without having to first remove the transmission.
