I've got a chance to pick up an older Campbell Hausfeld 7.5 HP, 80 gallon, 2-stage compressor for $250. The seller told me it is locked up (the motor is fine). He told me it was probably just a bent valve, which I got a good laugh out of thanks to my time spent here. Am I stupid for even thinking about this one? Would it just be a money pit? This is one of the older grey compressors, I think it's American made????
Would you buy a "locked up" compressor?

even with a bent valve you could turn it over the other way

Don't know.....used compressors and a VERY detailed look at the tanks innard's go hand in hand.Motors,comp heads,extraneous BS is all fixable.Rust in tank can be a deal breaker real quick.......gonna at least have to pull a big plug on side and get lights N mirror.......better is a camera used for scoping pipe.Freakin thing could be as new.....or an accident waiting to happen.Check that tank.BW
Good point on the tank, I will definitely check that out. Wouldn't a new compressor like this be in the neighborhood of $1500? What would be the most I should offer? I have to be smart here and assume it's worse case scenario to rebuild it.

$100 and not a penny more. then at least you could recoup your loss by scrapping the thing, probably close to $50 in scrap metal. if the motor runs (hook it up and find out), then you would be doing OK with $100. if the piston is seized, then the unit may not be rebuildable.

I haven't shopped in a while, but I would think that a CH compressor of this size would be easy to find new for 8-900. I bought a 6hp 60 gallon single stage for $399 new, but it has been a few years. The same model now is only $469.

Agreed, $100 max. And that's only if it is clean and the motor really works. If it was run dry of oil, the pump is likely scrap.

The above link will show you some pumps and prices. I would factor the price of a new pump into the sale and if you get lucky you may be able to rebuild the old one.

I wouldn't waste my time with it at any price. It's a cheap consumer-grade compressor and isn't worth the time to rebuild. Instead, I would keep an eye out for a Quincy QR-25 compressor. A 325 or 340 would do fine. Those are worth the trouble to rebuild to new condition.
The CH website is www.chpower.com they offer replacement compressors and just about anything else they sell through retail.
Here's the page on replacement two stage compressors.

I'm sorry I haven't posted pics yet. I don't think this is a consumer grade unit. It's rated for 21.7 CFM @ 175 psi. The closest thing I can find to (current Cambell Hausfeld) it is a CE7000 which is around $2200. My original thoughts were to buy it for $200 or under and hope to have $300-400 in rebuilding it. After listening to you guys it just sounds like I should let this one go. Thanks!

I've been there and done that. I wouldn't advise it.
Offer what you would be willing to pay for the tank. The rest has no value.

If you want a compressor to tinker with, buy it. If you want a compressor to do work, buy a new one. Very good compressors are available at a decent price, and a good brand new compressor will likely work for the rest of your life if you maintain it a little.

$250 is too much IMO
I am thinking like others in saying that I would go $100 with $150 being the max if eveything else is good and I really want it
you could look at installing one of those HF compressor pumps on it and just use the thing.
is it single or 3ph and which do you need?

it feels good to hear/see you say that. i bought a 325 in need of rebuild a while back and it has been sitting wrapped up under my workbench since waiting for me to get the initiative to rebuild it.
Tell us more about the motor. My thinking is this: a 7.5hp 1phase motor is well worth the asking price. If it's 3 phase, whole 'nuther issue.
Brand of motor is everything. If it's 7.5 consumer type it's not really 7.5, but if it's real hp, I'd give it a close look.

For $250 you could look around and find an IR or Quincy to rebuild if you hold out a few weeks. If you bought it at $250, by the time you were done fixing you would likely be into it what a good IR or Quincy can be had for on Craigs pretty easily, and still have a compressor that wouldnt resale for nearly as much.
IMHO, $50 tops if the tank is good and everything is shiny.

I was wanting a project, but I don't wish to get burned. It is a single phase unit, I actually just called the guy and asked for the motor tag info. I figure if nothing else I'll sell the motor and then sell the tank to someone for storage.

I'd buy for the cheapest price I could get it for and put a HF pump on it. $169 for 2-cylinder (not 2 stage, reed valve). Reviews say they will last 5 years or longer if you take care of them. Intermittent home use and keeping them dry I would think double that.

That's not only not a home-cheapo special, that's the exact same compressor that Grainger rebadged and sold under their Speedaire name for many years. They were a decent machine but it all depends on what's wrong with it. If you're going into it blind, you just have to know you're taking a risk and could end up with scrap value.
From some prior experience with CH's with low oil, it's a possibility it's seized a crank bearing. Crankshaft damage could be the dealbreaker.

He gave me the model #, I wasn't able to find parts support online anywhere which is a concern. He's at $250, I'm holding out for $175 or $200. I feel pretty confident that I could recoup that out of the motor. If I could cross it over to the grainger equivalent they have always had awesome parts support.

You are dreaming on the price. The Husky 7.5 hp two stage is the same compressor with a different color paint (its made by C-H) and when I bought mine in 2003 it was over $1600. At that time the C-H branded one was even more.
Does the pump say USA cast into the end housing opposite end from the pulley? If not, its a china pump.
They have changed the configuration since I bought mine, the motor and pump locations have been reversed, allowing a much shorter pipe from the compressor head to the tank inlet check valve in the top of the tank, rather than the side. This was simply a cost saving move. The pump was also changed to a China clone of the original USA pump, identical in all other respects.
These pumps have reed valves. Broken valves will not lock up the pump, and you cannot have a "bent" reed valve like a car engine would.
The pump linked to above is the one. While it says 80/20 duty cycle, mine said it was rated at 100% duty cycle if synthetic oil was used (I use the recommended Mobil 1)
I am yet to run into a 7.5 hp compressor that is not a full rated 7.5 hp. If it says 7 or 7.4 or something like that, then yes, its really a 3 or 4 hp, but if it says 7.5 and draws like 28 amps, its a full rated 7.5 hp
The pump in the pic on the C-H website clearly says Made in USA, but I think you will find the new pumps do not say this.
C-H no longer shows that complete compressor on their web site.
THIS is the current Husky 7.5 HP two stage 80 gal.......
Here is a pic of my 2003 model of the same compressor (motor by the way is a made in Mexico Emerson)........
Here is a pic of the C-H compressor that is identical to mine.....

This is the best picture I can come up with of the pump. There appears to be some words cast into to bearing cover but I can't make them out. I shot him an offer and an just waiting to hear back.

Thats the USA pump, see THIS LINK for an idea of what it looks like.
Is the magnetic starter installed? I don't see it, just see the motor wires and pressure switch wires running out of the pic. You can see where the starter box was installed in the pic looking at the shadow of paint on the RH side under the motor. If it doesn't have a working starter, DON'T bother with it, the starter is a must with this motor and is way too expensive to replace to make this project worth while.
