Wanting first impact wrench

[dstig1]

Anyone ever try to take the crank bolt off a 3.0 SHO engine? Or worse yet, a weenie little 1.6l I4 Honda? Good gawd they're on there to beat the band. I found time is your friend. Keep pounding at it even with a good impact wrench, sometimes up to 15-20 min of pounding - with breaks to let the compressor recover. But then I fixed that with a much bigger 2-stage compressor. I don't run out of air anymore

But then I've also found that some things just work better with a breaker bar. Sometimes the slow steady pull will loosen something the impact won't. It pays to have choices. My IR 2135TI is great - much lighter than the old 231 IR and more power. But sometimes the 24" breaker bar is the solution. We won't get into cheaters...

never had a crank bolt that my 3/4 cp gun wouldn't spin right off after a few hits.

Whats wrong with a 5 foot snipe?

It amazes me that every picture I see of a compressor, shows the compressor still mounted to the shipping pallet instead of properly sitting on the concrete floor, on machinery pads.

There was long conversation about this on here a while back.. Most people leave them on the pallet and after many years of use have never had any problems. I haven't got a large compressor yet, so I dont know the answer to this, but does the instructions say you must bolt it to the cement. Seems to me the wood in the pallet would absorb some of the vibration.

I wish my compressor was as big as those ones, mine is "only" 220v 3hp (quite good for someone who is 14 though)

I guess it depends on who is right when you say "properly.":laughing: When I bought a 60 gallon compressor from a business that specializes in building, selling, and servicing compressors and associated accessories, they specifically recommended leaving it on the pallet. And in my opinion, as with the experts I spoke with, they are "properly" sitting on the pallet.:laughing:

I cannot imagine any advantage to removing one from the pallet to mount it to the concrete unless you have a problem with vibration causing it to move around. Mine never moved at all. And one big advantage to leaving it on the pallet is in case you ever have to move it. In my case, when I sold the farm, the realtor bought the compressor; sure glad it was still on the pallet.

Tell me I'm nuts but this is compact tracor forum if the 1/2 inch won't do it you need a swing handle and a snipe to loosen it and retorque it or you guys have a lot more money than I have .I believe I have 1.25 " socket from Sears,that is a fair size. Just my 2 cents.

I have used several name brand air impact wrenches over the years. Got tired of dragging the air hose around and went with an 18 volt Milwaukee model 2662-22 M18.

This thing has all the torque I could ask for. Very portable.

Just sayin....

I've used this an found it to be quite adequate and a lot more convienent.
I guess I'm wondering why you would need a 3/4" Impact wrench? Are you changing semi truck wheels?

Years back, I wanted to change the timing belt on my Acura (nee Honda engine). Got out the IR2131 and tried to spin the nit on the dampener off and it just sat there and rattled. I decided that the torque was not being transmitted as the dampener rotated slightly with each hit thereby reducing the force. I built a steel "strap" wrench with a bolt to tighten it and a bar to brace against the ground to keep it from turning.

I hit it again and again with the IR and it refused to budge. Got out the 24" breaker bar and put a 4' cheater on and even with a little jumping on the bar, it would not budge. Strap wrench would slip.

The next day I went down to the bus barn and borrowed a 3/4" gun they use for bus maintenance. Put it on the nut and I swear I heard one click and the nut spun off.

Sometimes there is only one right tool for the job.
