Ingersoll Rand IR2131 vs IR2131A? Help

[ElliottG]

Hey guys

Was reading a few threads about the IR impact drivers on here and was just wondering what the difference was between the IR2131 vs IR2131A and how to tell them apart? I'm looking at buying an IR gun and want to know what I'm getting.

I was also looking at the IR2125 because it's a mini 1/2" driver...which would be perfect for me. I'm just wary of buying a used one because I can't seem to find a rebuild kit anywhere for it? Any info?

Thanks,
Elliott

The ir2131 is made in USA i dont think the 2131a is. The 2131 and 2125 are both good guns.

Thanks but here's the info I got from a really nice person over on eBay who sells rebuild kits for these guns:

Other than the anvil, the 2115 & 2125 are the same wrench. As for the difference between the 2131 & 2131A, it is also in the anvil. They are both 1/2" drive, but the early 2131 had a slightly smaller dia. anvil where it goes through the bushing. Later models used a larger dia. anvil and early models can be modified by installing later model anvil and bushing. All of the current models use a 231B-A626 anvil which fits all of the Ingersoll Rand models including IR231H, IR2131A, 2132, and also the IR2135 series. All of the 2100 series wrenches us the composite body with only minor differences

The 2130 is basically the same as the 2131 except it uses a different reverse valve systems. It has a lever instead of buttons. The 2135 is just the latest version of the design. It has seven vanes in the motor instead of 6, has a titanium nose cone, different buttons, and minor cosmetic changes. It can be identified by the nose cone and by the shape of the buttons. The 2112 and 2115 differ in that the 2115 uses a titanium nose cone, has better exhaust flow, and can be recognized by a red trigger and regulator dial as opposed to black. The 2112 can be upgraded to 2115 by replacing these parts. There is also now a 2115Max which has a seven blade rotor and different buttons. Generally, the numbers identify the series (first two numbers) and the design change (last two numbers). Also in the case of minor changes, a letter or series of letters may be added. Ingersoll Rand usually comes up with a design and makes minor changes & improvements with each new model while staying with the same basic design over a long period of time. Witness the old 231 series which has been in production for years as IR231, 231A, 231C and several other special variations and is still available as the 231H. Ingersoll Rand is terrible about marking their products with model no.'s but most are easily recognized by cosmetic changes, if you are familiar with them. Hope this helps and glad to if I can.

Hi! The 2131A is just the first design of the 2131 wrench. The 2131C has some minor cosmetic changes in the housing and more sound insulation supposedly to make it quieter and have less vibration. In all honesty, I've never seen one. The 2131P does indicate a pin lock anvil. It uses anvil part no. 231B-A726 which is a pin type anvil. This anvil and the ring type anvil are interchangeable and both can be used in any of the 2131/2135 models

Hope this info is good for other people as well!

I'm trying to find a tune-up kit for an Ingersoll Rand 2132g impact wrench with no luck at all. the parts blow up looks like the 2132g and the 2131 are internally identical. Does anyone know where I can find a 2132g kit or if the 2131 kit will work for the 2132g? The Kit number would be appreciated.


BTW if anyonce out there cares, the 2132g is a great wrench. First time I used it I though my wheel lug nuts had been left loose. But it was just the torque of the wrench that made them come off easily.


Thanks.
