Last night I heard a God awful noise from the shop. Sounded like a combination of a jack hammer and top fuel dragster.

The shop was full of smoke (burnt oil smell).

Shut the compressor down and figure something let loose inside.

Well, this morning, just for jollies, I turned it on and it sounded normal. I didn’t let it run long enough to build any pressure. There was oil in the sight, maybe 2/3 low.

I am thinking I’ll drain the oil, turn it back on and see what happens.

But for you experts out there, you think the compressor is shot?

Its a big one 5HP 80gal so I hate to think I’m buying another one.

I’m going to call a local compressor service and see what my options are.

That happened to me in one of the old shops I used to work in. I took the motor apart and one of the metal flaps that build the pressure, cracked/shattered and was flapping around broken inside until the broken parts completely got loose. Though it sounds normal you may find it not building pressure, basically like a ripped diaphragm. Yours may be something different, but easy enough to check.

I think you meant the compressor. The motor is electric and doesn’t have valves last I checked. ;-)

It does sound like oil got into the head of the compressor and was knocking because it won’t compress. It also sounds like it was burning oil. But how it’s burning oil without ignition (unless it’s dieseling) is beyond me.

I guess technically I meant the pump. ;)

Go to the manufacturer, buy a rebuild kit. These things are dead simple to fix. Anybody that can handle the intricacies of woodworking certainly has the capacity to do a compressor rebuild. If you have any questions PM me and I’ll help you through it.

Thanks Jerry. That thought crossed my mind.

But I called the a compressor service its $$$ for them to come out but I can bring it to them and they would check it out.

He asked me where I lived and one of the techs doesn’t live too far away, he is going to swing by after work and have a look see – at no charge! Not having to haul that beast in is really nice.

Wow talk about service!! I told him I would give the tech a nice tip :-)

Mine did nearly this same recently. Hopefully your fix is as easy as mine was… After an exhausting hunt as to what made it go haywire – large coarse tremor, wild noise, and sounding just straight up catastrophic – I found that one of the mounting bolts had sheared off. Simply removed the compresor motor from the mount , and reinstalled new mounting bolts (replaced them all, bc if one went…well). That was it. Bingo-bango. Hopefully you’ll be as lucky

Talked to the tech he said it sounds like a bad valve blowing oil thru breather. Which is excactly what it was doing.

The SS5 rebuild kit is $270. A new compressor is $489.

With even $100 labor I’ll probably buy the compressor. Frame of ref I paid $1000 for compressor on sale about 10 yrs ago.

The new compressor for $489 is most likely not an oil filled compressor, and is designed to be disposable. A repair on that oil filled one you got will most likely buy you another 10+ years.
I’ve got a Husky, Home Depot special 5hp 26 gallon oil filled compressor that I got new, oh late 90’s. Still cruising right along. Now the new ones look the same. But are not oil filled. Guys I know that have them seem to burn one up every 5 or so years. While mine just keeps on running.

That is an identical replacement just the compressor pump.

What have I got to lose, so I removed the compressor and took the head off.

There did seem to be some “scraping” as I turn the pulley. I don’t know if this is normal or not.

I removed the head and checked cylinder walls no scoring noticed.

As for the valves, I don’t know I’d what I’m looking at. See anything wrong? Is there supposed to be a big gap?

Thanks for your help!
