Craftsman 3/8" impact won't run!

I have a Craftsman mdl # 875.199460 3/8" impact that will not run. you can press the trigger and some air escapes, but it does not attempt to run or turn. i have checked the inlet and no obstruction and also pulled the bottom plate to insure no obstructions. none found. i removed the rear plate, but did not go any further. the gasket seemed stuck and i did not want to destroy it. What do you suggest checking. the unit has very little use. it seems like the air stream never get to the motor. ask for more info if you need it. Please Help!

    I have a 1/2 drive craftsman impact wrench. I thought they were better than Campell-Hausfeld, my personal experience they are not. My 1/2 dr. CH is still working after 5 years. Craftsman gave up after 5 uses. Both were oiled & oil circulated before use everytime. I will only buy CP. found out they have a 3 yr. warranty.

    I have the same exact problem after removing the rear housing i found in the bottom two corners the gasket was torn and somewhat moist ie oil had dampened it so it would seem the air is flowing mostly into the housing and not the motor area does anyone know where replacement gaskets can be found and not a covered piece of cardboard maybe an actual rubber or metal gasket

    I assume you have added plenty of oil into the air inlet? I would even try some Marvel Mystery Oil...amazing stuff...

Igersol rand or shinano are the best way to go

Thanks for reply, but the impact was oiled adequately. i was stored and when removed, it did not run. guess i will scrap it and buy another brand.

How do you oil a Craftsman Air Impact Wrench Model No. 875191182?

Just put 3-5 drops of air tool oil down the air inlet coupler and then run the gun for 5 seconds. Do this everyday that you run the gun for best results.

I have a craftsman model 919.165300 compressor 5 hp 30 gallon.It runs it builds pressure and shuts off like its suppose to. The problem is when I attach my impact wrench to the airline and press the...

first I hope that you drain the water out of the tank regularly. It seems as though you might have an air hose collapsing but in any case there is something apparently restricting air flow too the gun. try opening the petcock and see if you have steady air discharge or not and if you have another air hose try it. Also, are coming directly off the compressor to the tool or do you have an oiler or drier in line? if so, eliminate the accessory. Let me know how you do....I'm curious.

Dont know where to put oil in Craftsman 1/2 " Impact wrench

I just bought one of these also. Manual says oil goes into "the air inlet" which I'm thinking is where you attach the hose. That way the oil is sprayed throughout the interior of the gun once you run air through it.
Question for you: I can't get an impact socket onto this gun, almost seems like the square hole is too small. (yes, both are 1/2" drive). How do you get a socket on this stupid thing?
(man that sounds like I'm an idiot, but I've spent a half hour leaning all my body wight, wiggling, etc. and can't get a damn socket on)

My impact wrench when connected to the airhose stay on even though the trigger isnt pressed

you probably have rust and goo in the line and it has stuck the trigger open,run some air tool oil in and let it soak or better yet some penetrating oil to break up the sludge and then when cleaned out use the air tool oil to lube it

Where do i get a replacement trigger, mine is

If your local Sears store can't help you, try looking to see if you have a Snap-On, Corn-well, or Matco tool distributor in your area. Many air tools are manufactured by companies who make tools for different distributors. I work in a shop, and have found that many of the tool trucks have parts that'll work on other brands of tools besides their own.
