A driveshaft assembly (100), for example in an Electronic Unit Injector, Unit Injector or Electronic Unit Pump testing machine, wherein an indexing means (118,152,162), such as complementary external and internal splines, enables a cam (102) to be mounted on a shaft (112) at a number of discreet positions, each providing a different offset of a central axis (170) of the base cylinder section (108) from a central axis (114) of the shaft, each position providing a different maximum lift value of a plunger in contact with the cam (102) , directly or via a rocker arm. |
