IR 242-D stops really fast and makes a loud growling sound.

by Doug S.

I have a IR 242-5D two stage 5 HP. Compressor.


It pumps up to 140 PSI. Without a problem.

When it hits it's set point to shut off it stops really fast and makes a loud growling noise.

Are they supposed to stop so abruptly?

Noise

Probably not.

Hard to say without actually hearing it.

Still, could be a bearing going out. try turning the sheave back and forth - Other than maybe some valve noise it should be quiet. If there's any grinding noise, keep at it to find the cause.

Then again, if you're around to monitor it, you can wait for a bigger noise to make it easier to find, at the risk of something else (like a crankshaft) being damaged.

Good luck.

Rebuild kit for IR 242 D3 ?

by Mark

IR Type 30 Model 242 D3

I have a IR Type 30 Model 242 D3 or so the tag says.

I cannot find any info on the D3. Everything I have found is for the A or B 242 models.

Can anyone tell me what the D3 is and will the rebuild kits I have found work in it?

I need a high pressure side rod and wrist pin as the rod end at the piston is egg shaped.

Any info out there?

Thank you, Mark

D3?
by: Doug in s.d.ca

Yes, apparently that's a thing.

But usually, if it matters, the parts places say so.

But then you got A and B model gaskets, what to use on a D3?

But it also looks like the major stuff like pistons are mostly interchangeable.

So, I'd call whoever you get parts from - maybe where there's a question, like the gasket kit, you can get both and send whichever back.

(Yeah, you probably knew all that, but I'm interested in how this turns out, so need to comment)
