Thanks MacMcMac. I had read on here that the SB is cloned a lot so not too surprising.

Hi All, I'd like to use the experience pool here to help ID a compressor. It is for sale near me, but the guy selling it says there are no tags. Just based on shape I wager its a Saylor Beall 705 but the unloader looks different. Anyone have any ideas?

On further looking it doesn't have disc valves so not an r15.

The ground wire to the sub panel should be landed on the bond bus in the main. (Lower left of your panel) Neutral to neutral main to sub. In the sub there will likely be a green screw through the neutral bus that bonds it to the can. This needs to be removed in the sub panel. If you own a...

I'm looking at this compressor for 250$. It doesn't have a name plate on the pump, but it has a 3hp motor and a champion sticker. Anyone recognize the pump model? Also how big is that tank? A bit of reading makes me hopeful it's an R15 pump.

It does have a hand hole. I think I could fit my phone in there to have a look around

Hey jack I think it's a 3/16 ring. I did find them for some old motors. .185 is 2.96 16ths by my reckoning.

Yeah I'm getting a lot of that on this one. I have done some gnarly rebuilds before on tractors but the parts are easier to come by.

There doesn't seem to be any clearance between ring and groove. Measuring them says maybe a half thou difference and that could be tool quality.

I saw a set of lp pistons that were 20 over but then I would think you'd need rings 20 over

Yeah I imagined I was stuck getting new lp pistons. Didn't seem right they were sealed in like that. I'm not sure what the clearance in the groove should be. Tiny I'd bet.

Ring width is 185.5 to 186.0 thou, ring depth 130.5 to 131, 3.25 bore. Piston groove is about 171. If anybody has a ring reference somewhere.

Positive update this time. The crankshaft is perfect. The bearings are good and smooth. Measuring the rusty bore shows it to be around two thousand under in one spot but good elsewhere. I'm not sure how to proceed based on that but I'm talking to my machinist buddy about sleeving. The other...

Thanks Jack. That thought had occurred to me. I imagine that the 3.25 bore can't be that rare a thing and surely other compressors used these pistons. Where did you find piston and ring sizes to compare?

I actually got this based on a previous rebuild I saw on here. It certainly seems like a very capable pump, it's just a matter of hunting the parts. Everything seems mighty expensive for it!
