Question about Ingersoll Rand Type 30 Reciprocating Air Compressor 5 Hp, 80 Gallon, 230 Volt 3 Phase, Model# 2340N5
I'm trying to renove an ingersoll compressor t30 3"&1-3"/4 x2-3"/4 model 234.
The serial number is 8802263. I have ordered a seal kit, valve finger for the full unit but some seals do not fit one cylinder head (the "small cylinder" => is there different T30 models?
I received a plate with 2 valves on it but this cylinder use 2 separates valves...
Do you know where I can find the parts and service manual for this compressor ?

the wire juction box on your compressor has a pressure switch that may be wound in to tight take the cover off the box there should be a switch with a machine screw with nut and washer and spring back this nut off and see if that helps if you go to far you just crank it back in until the switch hit although it may be the other way around you may have to tighten to lower the pressure some of them are made that way if this does not solve your problem send me a picture of the switch and can solve it from there

The best way to go about the task of adjusting the pressure switch is to remove the cover to switch and note the brand/model number. Sometimes instruction are under cover of switch. With switch information, look for mfg. instructions. You will most likely see one or two springs with lock nuts. Do not turn them yet. Most pressure switches are sold with factory adjustment and are sold in pressure ranges. For two stage compressors as yours, the pressure is usually factory set at much higher (150-175) pressures than single stage which is usually about 120 -125. If you change the pressure setting it will also change the differential cut on pressure. The factory will actually use different springs to achieve desired pressures and are color coded. There are too many different brands of switches to recommend how to change pressure setting. You may discover that you can only change the pressure just a small amount (+or -15-20psi ). If you find the information about your switch, make sure that you count the turns exactly so that you can return to factory settings if things go wrong. You can extend the life of the comperssor by lowering the pressure as more amperage /heat is produced to achieve higher pressures. Good luck
