Help Identifying parts on Compressor

[tacorican]

I purchased this really old compressor from an Estate sale. It works. But I want to do preventive maintenance.
I can't seem to find the Filter, what oil it uses etc. Are there any seals I should replace?
It is a 30 Gal Ingeroll Rand Compressor but I'm not sure what model.






Thanks in Advance

Don't think it has an oil filter, air filter should be in that funnel shaped housing sticking out of the side of the cyl. opposite the copper tubing. If you can't find compressor oil, straight 30 non detergent should be fine. I wouldn't start replacing seals that aren't leaking, why go looking for trouble? Wiring looks a little shaky between the motor and switch, might see about replacing that.
Good luck, Jim

on the lower right side - the butterfly is your oil fill and inspection, square head plug below that is the oil drain. typically you fill to base of fill hole, as stated above use compressor oil or ND 30. the funnel looking thing is the air intake clean it and replace element if it even has one - or best would be to replace with modern paper style filter head inlet will be pipe thread. remove the four head bolts and remove the valve plate, it will have reeds on both sides clean plate check for flatness and replace reeds. parts are easily found online just Google: ingersoll compressor parts, gaskets, reeds, filter, etc....

An old compressor like that will be just fine with non detergent 30 weight oil.

I'm in a similar situation with dads old Sears 20gal model 106179880 - it runs great but I'd like to overhaul the wiring so I sleep well. Are these parts (wiring box) standardized and rather simple to get ? Any product recommendations are appreciated.

The " wiring box" AKA pressure switch is pretty much a universal item, yours doesnt appear to have an unloader valve on it. I wouldnt worry about the pressure switch unless it's giving you problems. the rest of the wiring could be cleaned up /replaced

Ok- it functions so I'll leave it alone.
I'm assuming that switch keeps the pressure correct and in check?
The housing to the electric motor - Is that motor something I can disassemble and repaint ? I would t want to attempt to refinish it with the electrical guts in it.
- also any recommendations on gauges? Thank you so much.

The pressure switch controls when the compressor starts and stops running. You could try and repaint the motor if you want but I wouldn't mess with it, its working now don't be taking stuff apart and messing with it because that's usually where the problems start is people messing with stuff.

I'd just buy a set of gauges from HF...don't need anything fancy at all.

I actually have the same compressor except mine is red and says Montgomery Wards on it and only has a 1HP motor. Pump on mine is the same as yours, my regulator/pressure switch are in a bit different place. Great compressor, just the tank on mine failed after 40 years.

^^ ok will do. Speaking of the tank - mine looks fine aside from a little surface rust. Any precautions to take there ?
- and how do you know there's enough oil in it - just fill to the top of where the full plug is?

Tomorrows list - replace gauges , replace wiring , wash tank with soap and water, buy non detergent 10w30.

No, non-detergent 30W. The Walmarts in my area carry it. And yes, fill to the top of the threads on the fill port.

On the tank, search on this site for 'hydrotest' - that is where you fill up the tank completely with water, and then pressurize the water (typically using a grease gun) to safely check the tank integrity. There are plenty of threads on this.
