Hi Bill-


I have spent a bunch of time prior to posting this searching your website, the web, and IR's website. Apparently this is too old??

I bought an IR T-30 model 242-5n at an auction, expecting to do some rebuilding (I was assuming it needed compressor rebuilt). Much to my surprise, it runs and makes air, no funny noises, no knocking! But it does have a couple issues:
1. The motor starter "bounces" as it shuts off. I am working on the solution here....but see next issue
2. the motor nameplate says 30 amps....but it runs at 33 amps as it pumps up. (only takes 5 minutes to pump up, seems normal)
3. In diagnosing the motor, I realized it is spinning backwards from the mark on the flywheel (CW looking at the flywheel, arrow says CCW). The electric motor is reversible, haven't tried it yet.

My questions are:
1. DO all IR compressors spin CCW? My research says most do, but maybe not all?? Does it hurt/work to spin it backwards?

2. DO you know the specs, particularly CFM on this unit?

3. Any idea where to get the owners and repair manuals for this? They are NOT on the IR website, and I don't see them anywhere else.


I'm guessing I may have to have the motor rebuilt, replace the motor starter. Tough troubleshooting without these manuals and specs.

Any help you and your members can offer would be appreciated.

If more pics help, let me know how to upload, it limited me (big pics)

Thanks,
Jon

Most all do, not sure if any IRs are different.

2. DO you know the specs, particularly CFM on this unit?

Not sure what exact motor yours has, but see engineering data sheet

3. Any idea where to get the owners and repair manuals for this? They are NOT on the IR website, and I don't see them anywhere else.

Seems I saw scribd had it, but I didn't choose to sign up.
