The Continuing Saga of the Commodore's Cruiser

Air System Rebuild

Courtesy of Richard "Arch" Archer

Richard Archer("Arch") is in the process of rebuilding a 1976 Glenbrook with 128,000 miles that he purchased for $5,000. This is another installment in the continuing saga of one man's adventure with a "bargain" GMC.
It's hard to say whether this is the original compressor or not, but it's long past pumping any air now. It will either need to be rebuilt or replaced.
Apparently, the original air tank rusted out and the previous owner fabricated this one out of well casing and sheet steel. In addition to the questionable safety of its construction, no provision was provided for a drain. According to Arch, it was "one third full of the nastiest black goo you ever saw."
Arch purchased a new steel air tank from Cinnabar Engineering along with their "Improvement Kit", including 5 micron filter, check valve, moisture trap and quick disconnect. If he had it to do over again, Arch says that he would go with the stainless steel tank from Jim DeMaere, as advertised in GMC Motorhome Marketplace. It's less expensive than the OEM tank and corrosion resistant also. Unfortunately, Arch received his first copy of GMCMM the same day his new air tank arrived.
Originally planning to rebuild the compressor that came with his Glenbrook, Arch stopped by a truck stop that was going out of business. While browsing through the parts, he spotted a Hadley V-twin compressor nestled in with the air horns. Its specifications and price seemed right, so Arch picked it up to replace the tired compressor that came on his coach.
Here's the completed installation. All hooked up and ready to roll.
