Pond Boss Forums Thread Like Summary - Thomas 2660 rebuild kit

Hi guys. It's been a while since I've logged on here. Been suffering with back problems for the past couple years and barely able to keep up with the property maintenance.

Anyway, my aeration pump is due for a rebuild. Where's the best place to buy an overhaul kit for my Thomas 2660 pump?

I see one available on Amazon but I'm leery.

If it's got any age on it you will need the cylinder sleeves too. If the kit doesn't come with screws, pay close attention to the ones that you remove. If you see any sign of brown or blue paint on the threads, make sure you use blue service removable loctite on them when putting them back together. NOT the red stud and bearing mount stuff.

The two hardest things will be getting the fiber "ring" to be installed correctly in the sleeve once it's on the piston, and getting the reed valve (flapper valve) to stay in the correct place as you are tightening up the screw that holds it in place. The reed (flapper valve in the video) has a washer on top of it. There is a rounded side and a straight 90° angle side. The rounded side goes down against the longest part of the flapper valve. Putting the sharp 90° edge there will create a stress point and prematurely break that flapper valve.

I'd rather rebuild 3-5 Gast Rotary Vane compressors than one rocking piston compressor.

Look at Thomas itself or Mack Industries.
