In order to locate cracks or holes in the engine heads, all parts are capped by a plate and rubber pad.  This is done via use of hydraulics coupled to clamping arms and forming an assembly called a CAGE. 

The test is performed under water with the head given an air pressure.  The water is heated and causes small cracks to open so air will escape.  The operator looks for any air bubbles and will mark these areas.  To look at all sides of the head the clamping cage is made to rotate via hydraulics.

 Water level can be adjusted instantly via means of air pressure forcing water out of a double chamber test tank.

We can move 52 gallons of water into the test area completely covering the head under test in less than 2 seconds by this means. 

Also the test area is illuminated via underwater lighting.  PLC controls are used to operate the various parameters. 

This equipment has increased production output from two shifts to 1/2 work shift and reduced operators from two to one.
