Pneumatic wrench opinion

[Arbybe]

For those of you that have repaired your impacts;
Do you suppose that the average user goes over 100lbs
Causing failure of rotor spline, anvil, cage, etc.
Or could it be lack of lube, moisture, or other abuse?
This seems to be a weak link and as we've seen, some changes have been made.
In production.
With even a warranty of just a few months, I feel it would drive a mfr out of business
In short order if nothing but junk was produced.
I have had very little tool trouble over my life time keeping the pressure under
100lbs
Let me see what you have to say....

I occasionally disassemble my pneumatic stuff to get rid of

any unsightly bacteria (etc) that accumulates, which I feel has

aided and abetted the tools to keep in good working order

for much longer than some of my other playmates' seem to last.

As far as pressure, my compressor ranges from 120 psi to

"it won't make the wrench go" and I have never regulated

the air supply. I know that most tools ask for a steady 90 psi

but I don't really think that it matters all that much. More

like "cleanlyness (and lubrication) is next to Godlyness."

I would have to say quality is the most important factor. My old shop had a ir231 shop gun that I'll guarantee didn't get oiled once a year. They also didn't have regulators & I doubt the filter was ever serviced. My first one was a craftsman & lasted about a week

Air tool power is governed by mass flow rate through the tool, since the inlet area is typically fixed* pressure is the driving factor. Thus increasing pressure into the tool will increase power and speed. Unless you are drastically running over the 90psi recommendation, I'd be willing to bet failure is more likely to come from lack of lube, contamination in the air line and or hard service.

*Why hose and fitting diameter can make a difference.

I'm thinking most impacts & air tools fail due to lack of maintenance by the owner, just like most cars fail due to lack of maintenance by the owner. I run my tools at 120psi, keep everything clean and oiled, and I haven't had many issues.

I try to keep the pressure at 90 psi since the manufacturer recommends it. So far I haven't had to increase it for any reason.

I do add a few drops of tool oil every time I get the impact out for use to make sure the oil will get worked in right away and not drip out. I think this is important in my case since I am using a cheap oil-less compressor and don't have an in-line oiler.

I take care not to drop it or throw it around.

When putting my impact away I try to store it so the quick-connect is horizontal and open. That way moisture from the air line that is left inside the impact can evaporate and escape. I don't point it up because dust and especially fine saw dust would fall in.

To sum up: I don't hit it harder than is needed. Oil in. Moisture and contaminants out.

It's still pretty early in the life of my impact wrench but I expect my simple precautions will help it run a full service life.

i dont bother repairing my impacts.
they give a reasonable service life of 8-10 years. by then it needs an anvil, hammers, seals, ect.

i can have a brand new one at my door within a couple days...
and keep the old one as a spare/home garage gun..

Way more people run 120 to an unregulated 175 than you'd believe. I don't see large failure rates. My old IR2131 performs noticeably better at 120 than 90.
