Air and Heat, Compressor Bracket

The compressor bracket provided by RCR arrived in several pieces. The idea is to have the parts welded locally due to the variations in engine builds. Not having welding equipment, we made up a jig and took the pieces to our local welder. He did a decent job. With a bit of grinding and shaping, followed by a coat of low gloss engine black paint, we hade a nice, sturdy bracket. It is a simple design but serves its intended function well.

The lower adjustment bracket is a simple flat piece of steel that fastens to a water pump bolt on one end and to the rear compressor bracket on the other. There was about a 7/8” mismatch because of our particular configuration, so we made two cuts in the bracket and had it welded back in place with the necessary offset.

A 40” belt fit perfectly.

The compressor was secured to the upper bracket with a 4 inch bolt and to the lower adjustment bracket with a 4 ½ bolt, utilizing the threaded fittings on the compressor.

Before the compressor was installed for the final time, the oil pressure sending unit was installed. The supplied extension was not long enough to clear the compressor, given its more rearward location in our particular set up, so we purchased a second extension and a female coupling which places the sender out far enough to clear the compressor, engine and oil filter. (We will be installing a remote oil filter at a later date). No Teflon tape was used, since an electrical connection through the fitting is necessary.

The lower radiator hose was carefully routed between the compressor and lower pulley. It is a tight fit. We cut the end off of the same section of hose that provided the 90 degree right angle for the thermostat cover. (Part number D71281, from Advanced Auto Parts).

The compressor electrical connection required that a separate wire be run from the compressor to the trinary switch at the front of the car. This wire is not a part of the Painless kit. No relay was used in this circuit since none was recommended by Hot Rod Air.
