[Shop-talk] Impact seems...weak

[Douglas Shook]

100 psi should be good, but you also will require sufficient cfm to apply the force necessary (e.g., 1/2" lines would be great, pressure regulator has sufficient cfm rating, etc.).

Best,

Fellas,

I'm re-organizing the new garage. I haven't set up new big compressor yet, so I've been working with the contractor model I used around the house (135 psi, oil-lube contractor model--I've actually been pleasantly surprised).

I found my old IR2131 in a box a while back--it's been in that box since maybe 1999. Before that it was used maybe ten times, total.

I dumped some air tool oil in the intake and it spun. I was going to rotate my tires yesterday, and it wouldn't remove the lug nuts.

Now to be fair, I couldn't get them off with a breaker bar, either. But the gun is supposed to be better than 600 lb. ft., IIRC. I should have spun those off no problem. I wouldn't have ever used it at more than 100 p.s.i. on the old compressor, so it shouldn't be lacking there.

I thought maybe it needed a rebuild, but before I do it I thought I'd ask you guys. Do these things just 'age'? I remember pulling apart other impacts in the shop back then, but I don't remember their guts. Maybe a seal has dry-rotted?

Or are tire shops just sticking wheels on tighter now? I couldn't budge that thing with an 18: breaker and everything I had.
