Spline wrench

Abstract

A Spline Wrench is disclosed for manually rotating clockwise and engaging a power take off (“PTO”) drive shaft of a tractor, truck, aircraft, or watercraft having six or more splines for aligning the PTO with a female coupling of a machine, tool, or equipment, such as a mower, tiller, combine, water pump, air pump, fuel pump, compressor, generator, or other similar machine, tool, or equipment. The apparatus is used to rotate clockwise and align the splines of a spline shaft manually without having to engage the engine and transmission and pulsing the shaft to rotate it into position. Various embodiments of the Spline Wrench are designed to engage the splines of a Type 1 540 RPM 1 3/8 in. diameter 6-spline shaft, a Type 2 1000 RPM 1 3/8 in. diameter 21-spline shaft, a Type 3 1000 RPM 1 3/4 in. diameter 20-spline shaft, and a Type 4 1300 RPM 2 1/4 in. diameter 22-spline shaft.
