Speedaire 5z185a compressor repair

I recently inherited a speedaire 5z185a compressor. its been hidden in a shed on a farm for awhile. my question is: is there a diagramatic drawing for these compressors? Some of the lines are no longer hooked up and the regulator union has been broke off. I know I will have to drain the pump and basically clean everything to a spit shine, but i just don't know where all the lines go. Can you help?
Bill answers...Hello Sean. Nice to hear from Mo.
There's a couple of things you can do to help you figure out where all the air lines go as you start to rebuild your compressor.
The first is to go to the Nav bar, click on the Speedaire link, and then follow the guides to finding out where the nearest Grainger / Speedaire office is.
Contact them to see if you can get a manual.
Failing that, pop into your nearest big box store with your digital camera. Have a look at the compressors on display, and take photos of those that are similar. Ask the clerk what lines go where and why. They might not be able to help, but then again, they might.
A basic DIY compressor is not complex as to it's plumbing.
You'll have a line that runs from the compressor head that is Tee'd, so that the line goes down into the tank through a check valve, and also over to the pressure switch to allow the compressor head to unload.
The tank will have a discharge line that's normally connected to a Tee as well, and also through a regulator to a checked coupler, into which you would connect your air line.
Hope this helps.
Cheers,
Bill
