Old compressor fix??

[Matthew3901]

So i have this old compressor thst my Dad has been using for 25 years and he picked it up used at an auction. So it has a pinhole in the tank...
I have the thought of pulling off the moter and pump and scrap the tank and replace it?

If you can find a cheap (good) tank go for it, otherwise, better to look for another complete compressor. ( unless it has sentimental value)

2nd vote - keep motor and compressor - looks like a solid old brute. Scrap the tank and replace with new.

New tanks are often fairly expensive. I'd think you can buy a replacement used compressor for less than trying to fix this one. But we don't always do things that are more cost effective for one reason or another.

So it looks like i am going to just get him to replace the unit and i will hang on to the upper unit.

Find another tank as suggested. Keep that compressor head, it is the same Speedaire head I use, and a decent one.

I see lightly used compressors all over CL, some with junk motors or junk compressors and others that aren't yet junk but soon will be (oil-less direct drive units, etc). You should be able to source a good condition 10-30 gallon tank for $100 or less if you have a little time on your hands.

Definitely scrap that tank (or build yourself a nice BBQ smoker out of it) but keep the motor, pump, pressure switch, etc. Word of warning for that pump, don't leave it outdoors. The intake is on top, and I've seen a few that have been rained on and let the cylinders fill up with water, causing the cylinders to rust and seize the pump. Keep an eye on CL, you can probably get another complete compressor with a failed pump or motor for just a few bucks. Tanks are pretty generic, so as long as you find one between about 15-30 gallons you can swap the parts over easily.

Can't be in as bad of shape as this one...

 

[Matthew3901]

So a few questions about this compressor...
1. I know it is better than oilless for at least noise level, but other than that I looks cool...not sure of other advantages

2. old brute is still working fine, but the PSI is only set at 100...not sure if I get say a 150 psi oilless and swap Can I up the PSI?

3. also the pressure regulator that is attached is shot...needs replacing

If it has a pin hole, do NOT take chances with running it at all and certainly not up to any pressure. Be safe, not sorry.

 

[Matthew3901]

No I am going to separate and junk the tank and possibly find a compressor that has a bad motor and swap my pump and motor on it.

That pump (it's a Campbell Hausfeld VT by the way) is good for 150 psi. I've got one made in '68 set up that way from the factory, with a 1.5 hp motor on a 20 gallon tank. If you end up going with a larger tank, I'd dial back the pressure a bit just so the duty cycle on the pump and motor isn't as high.

 

[md21722]

Single stage pumps loose their effectiveness over dual stage past 100-110psi. Past 120 they can drop 30-40% of rated at 90 psi. And 90 psi at the tank is probably 65-70 psi at the tool.

So I'll post pics when i get it disassembled

As above, there are a lot of oilless or bad compressors out there. I have had whole compressors given to me that wouldn't pump up due to bad head gaskets or crud in the valves. Easy to fix, but in your case, with a good pump, easy to swap over to, also.

Anybody ever use an old air bubble for a tank? I wouldn't think they would be rated or tested the same, but we still fill them the same and they take getting banged around a lot.

So I pulled it apart today and cut up the tank ....you need to definitely drain the tanks

Maybe you could search Craigslist for a Hf compressor with a bad pump or motor

 

[Matthew3901]

Yep that is a plan!
