Well here I am again, asking for help from the OCC guru's!
In my incessant online searching of all things that I "need" for my shop, I came across a Trades Pro 30 gal 5hp air compressor. Looked good, price was way too high, but specs seemed good for what I'd do; 5hp, 75% duty cycle, 5.6-6.4 SCFM flow, and 125psi max pressure. Anywho, got the guy to a good price for it and made the deal. Got it home and fired it up. After a quick diagnostics, I changed the oil (who knows how long it'd been), replaced a few leaky fittings, and gave it a go again. After 15-20 minutes, it still hand't pumped up to full pressure. I'm guessing it got to about 60-80 psi as the gauge was just about beyond readably fogged up.
I'm guessing the rings are bad on this as it shouldn't take that long to fill up. Basically, I'm pretty new to compressor workings such as this and want to know if it's worth putting a few bucks into this to get it back to repairing. Here's a link to the service manual, parts breakdown are on pages 17-18. I'm guessing I need parts 10 and 11 (rings for the piston) but I haven't torn into it yet so I'm not sure. Where should I start with this thing? Thanks guys!
