In a fan spacer adapted to unite existing fans with existing pump drive shafts and pulleys on an engine, the combination of
- a spacer body having a bore adapted either without reaming, or with reaming, where required, to fit any of said shafts;
- an axial fan centralizing boss on one end of said body, said boss fitting a bore already provided in one group of said fans;
- four primary radial slots in said body for accommodating four parallel bolts disposable freely at varying radii from the axis of said body and screwing into tapped holes already provided in said pulleys to secure said body axially to one of said pulleys;
- and
- four secondary radial slots in said body equally interspersed circumferentially between said primary radial slots and accommodating another four bolts for securing said fan to said body by extending said bolts through said secondary slots and through bolt holes already provided in said fan.
