Quincy 310 Compressor (How Old)

[OverkillYJ]

Any info you guys could give me about this thing would be awesome. This came with a garage I just bought. I know the basics about it like it is a 2 stage. I requested the manuals and things from Quincy, but haven't heard back yet. I just saw a You Tube video with a guy running one of these he said was from the 20's. That one I think was a 310-10. This one is a 310-22 as you can see in the pic. Sorry the pics aren't great. This thing is mounted on top of the garage bathroom and is close to the roof. I also have some insulation repair to do.

Basically, how old is this thing? What oil does it use and how do I change it? Is this a good motor to use for it? Are the RPMs correct? It runs great and builds pressure fast. It is set at 150PSI currently. I also am having a hard time telling what size this tank is. I thought it was an 80, but after seeing other think it may be a 60.

EDIT:Cant upload pics for some reason. I keep getting a security token error.

Welcome to GJ Overkill

As for your compressor... I don't know much about the 310, but am familiar with the other quincy series. I currently run a 270 and use to run a 230 quincy.

Any info you guys could give me about this thing would be awesome. This came with a garage I just bought. I know the basics about it like it is a 2 stage.

Yea it is the smallest 2 stage comp that they make IIRC yet still a good size comp. I think they were typically found on small portable compressor units. ~3hp, ~10cfm 90psi pressure lubricated, some (I think) had hydraulic unloaders on the head for easy starting. 400-900 RPM input. Obviously the faster you run it the more HP you will need and the more CFM it will produce.

That surprises me, Quincy has always been extremely helpful when I have called them (Many a times over the years ). As for age, that is going to be based on the second number "-22" that is called the ROC or record of change number. It is like a serial number that tracks the changes to the pump over time and thus applicable parts for your specific compressor. It will give you a time frame in which the pump was built.

What oil does it use and how do I change it? Is this a good motor to use for it? Are the RPMs correct? It runs great and builds pressure fast. It is set at 150PSI currently. I also am having a hard time telling what size this tank is.

Oil.. Well of course quincy has their specific quincy brand oil. But usually any good quality 30w NON DETERGENT oil will be fine.

I have no idea what motor you have so I cannot state if it is a good motor or not.

Likewise I have no idea what RPM the pump is running. The range for that pump is 400-900 RPM. I settled on ~725rpm for a break even between power needed, noise, wear on the pump and ultimately air output. You will have to calculate your pump RPM.

Pump rpm = (diameter of motor pulley/diameter of pump pulley)*motor RPM

If you time the compressor from empty (0 psig) to full (note cutoff pressure) you can theoretically calculate the output CFM of the pump.

As for tank size, again I have no way of knowing. Just measure it and do the math.

Hope this helps.

As for the pics... IDK. Maybe try reducing their size? Are you trying to add them as attachments?

Yeah, for the motor and tank and stuff I wat going to upload pics, but they keep failing. I will get them up though. Thanks for all the info.

Even with pictures, I won't be able to telepathically determine the dimensions of the pulleys and tank.

 

[OverkillYJ]

Here we go. I guess the file size limit is smaller on here then other forums I am in.

The compressor guru's here on GJ will need measurements on the pulleys so that proper RPM can be determined.

Also might measure the tank, but sure looks like stubby 80 gal to me.

Now would be good time to Update GJ Profile with at least Country and State (or State / City in USA) so you'll get best local advice as well.

I rebuilt one from the bottom up. I can't remember my thread title though on here.

A.O. Smith makes good motors.

For the age, assuming the pump and the tank are original to each other and one or the other hasn't been replaced, look on the front of the air tank, opposite the side you took a photo of. There should be a plate welded to the tank with the maximum operating pressure and temperature stamped on it, the thickness of the metal used to make the tank, and also the name of the maker of the tank and the year it was made.

OK, last year I created this thread on my Quincy 310 Model 22 built in 62, and changed the oil like suggested.

Recently I started to notice the ball valve was kinda warm when I would open it for the lines to my lift and along the walls. The ball valve is about 2-3ft of pipe from the compressor.

Today I noticed it had oil dripping from the bottom of the tank. I climbed up to it because it is over a bathroom, and it has motor seeping from where the cylinder meets the crankcase. So I called Pacific Air or something and they are shipping me the gaskets from quincy for $40 to my door.

I assume that is all I need? What else should I do? I am guessing it will be pretty straitforward in regards to clearing out that little radiator tube in the front and bending a couple fins strait. I noticed some of the smaller piping running around looked like they had something missing on the ends of them. I put my finger over them and they were vacuums. There is on on the top of the motor, and one on the left hand back corner where the little square plate is. I assume they should at least have air filters on them right?

Any cleansors specifically for this job? Anything I should check in particular? Known places of wear and things. The only stuff I could find on this are people with different variations.

Cash is tight because I just sold the motor in my Jeep and have it almost down to the bare frame. I am on a spending spree for Jeep parts, not compressor parts. Body is all disconnected and comes off this weekend. This thing is heavy as hell and 15ft in the air against the inside of the roof. So if there is something I should do while I have it down I will sacrifice if I have to.

Here are some pics I took.

Just joined as a new member because I was looking for info on what looks like the same compressor. I know this is an old post but thought I would start here first. I am curious how you hooked yours up as for compressor RPM and motor size. I do not have 3 phase power available so would like to use a single phase 220 volt motor but not sure how big I need. Any help would be appreciated.

Hi and welcome to GJ! Need info on your pump to be able to give you useful info in reply. Does it have a name plate? Do you have any photos?

 

[toh4od]

Here it is. Have owned it for at least 10 years and been saving it until I could put it to good use. Any advise or help would be much appreciated.
