The old adage about an ounce of prevention is more important than a pound of cure was never more true then avoiding compressor body leaks. It’s well known that Harrison six cylinder compressors, particularly the DA6, HR6, HD6 and HT6 models, can have body leaks. Since most of these brackets are cast aluminum, warping is highly unlikely as a cause of leaking.

HT6 uses a single solid bracket and the key to avoiding leaks and other problems is a solid fit of the compressor in the cradle and bolt torquing. First, to assure a solid fit in the cradle, rock it the compressor. If it goes back and forth, place a shim or standard washer between the compressor and the bracket.

Then, torque the four bolts evenly and alternately, making sure the compressor remains solid in the cradle before the bolts are torqued. Unless they are torqued properly, as the bracket materials is heated and cooled in the engine compartment, the bracket and compressor can twist or rock to conform to each other.

In addition to avoiding body seal leaks and increasing the compressor life span, careful cradle fit and proper torquing will also reduce vibration and noise.
