A large Power Functions XL-Motor is used to drive a 2x 16-tooth gears via a a third 16-tooth ear). The 16 Tooth gears each drive a CAM made from 1×2 thin type Liftarm. The other end of the 1×2 thin type Liftarm, shown RED in the CAD Drawings below, is connect to a shaft which traverses the top of a Pneumatic Pump.

The Power Functions XL-Motor could be replaced by a RC Race Buggy Motor (Part #5292), which runs faster. Also the old style Pole Reversing Switchcould be replaced with a newer Power Functions Control Switch.

A couple of extra LEGO Pneumatic Air-tanks (Part #67c01) are advisable if you intend to use more than a couple of Pneumatic Cylinders. Using 16-tooth Gears speeds up the compressor, but you need fresh fully charged batteries for optimum results.
