110V Air Compressor Rebuild
It's my observation that many air compressor performance problems are caused by dirty/malfunctioning reed valves. The compressor must run longer resulting in more heat build up and the associated problems caused by heat. My compressor showed virtually no wear on the cylinders. The motor ran fine and the bearings are tight and smooth. I ordered a service kit (GAST K260 , $103.12 shipped to me)from Isaacs Fluid Power Equipment Company (888-336-8501).
This job can be easily handled by one person but a 2 year old grandson makes it more fun!!
Check the flatness of the mating surfaces with a flat file to assure a good gasket seal.

Great post Dean. Adorable Grandson also. I replaced my 120 v air compressor several years ago and so far it is doing well although when I keep the air up in the system for long periods of time it does cycle in about every hour or so. Need to track down some additional leaks and fix them but it is within Newell's guideline of "40 minutes or more between cycles".

Hey Dean, what symptoms led you to rebuilding your compressor?
Just wondering if it should be a maintenance item to put on my list.
Thanks,
Forest

Not sure about Dean's case but in my case and several others I am aware of, the compressor would pump up the system but it would take longer and longer to build pressure. Then as the situation continued, it would never reach the cutoff pressure. About 80-85 psi was all it would muster and that was taking 12+ minutes to go from 70 psi to 80-85 psi instead of the 2 minutes it typically takes to incease the pressure by about 25-30 psi.

Yeah, it took too long to build pressure.
Also, since I know very little about this coach's history I triaged each system and am rebuilding accordingly.

Living in the coach fulltime and using all of the equipment my compressor goes on twice a day maximum of three. Have gone through the entire coach and replaced all of the check valves, air switches, air control valves, etc. Its a lot of work but worth the time. I also had two of my large air tanks and the small air tank for the toilet with leaks in the welds and replaced them at the same time. Lots of places to look for leaks but on mine it was primarily old equipment wearing out. I want everything to work and try to keep up with it as quick as I can.
