PCT No. PCT/US81/00780 Sec. 371 Date Jun. 10, 1981 Sec. 102(e) Date Jun. 10, 1981 PCT Filed Jun. 10, 1981 PCT Pub. No. WO82/04481 PCT Pub. Date Dec. 23, 1982.A test stand (10) having a principal use for testing a fuel pump and associated governor (24), has a drive shaft (16), an inertial weight (30) operatively associated therewith, and apparatus (56) for selectively engaging and disengaging the inertial weight (30) with the drive shaft (16). This test stand (10) solves the technical problems associated with present test stands, which problems include the inability to maintain a constant drive shaft speed for fuel pump calibration, and also the inability to thereafter rapidly increase or decrease said drive shaft speed for purposes of determining the governor response. The apparatus (56) can accommodate misalignment between the drive shaft (16) and the fuel pump (24). The test stand can also include a spline arrangement (108) which also accommodates misalignment between the drive shaft (16) and a cam shaft (99) of the fuel pump (24).
