Bus tools ?

We love our 3/4" drive Chicago Pneumatic. Like new after 30 years of use!

What's the part number or model number or name of the "good" Milwaukee impact gun ?

Model # 2864-20
Model # 2867-20
Model # 2868-20|
Model # 2869-20

Nice, but friggin expensive.  But when I look at a good quality air impact, they aren't much less.

Should I be looking at 3/4" or 1" ?  What torque rating ?

My porter cable snapped the square head off a 3" 1/2" drive extension but would not budge it.

I couldn't budge 1 bolt with 24" breaker bar with a 4' cheater pipe slid on it so really I had about 5' of breaker bar and still never got it to budge.
So the guy that was there said hang on a minute and came back with that Milwaukee, I laughed and told him see that impact over there, it didn't phase it.
He said humor me, and so I did and WOW that BAD SOMEBITCH zapped that bolt right up out of there!
I didn't get the model # as I was loaned it for the 1 bolt, and handed it right back to him.

I would either go with the BADDEST 1/2" drive or 3/4" drive battery powered one you can get.
They are much handier, smaller, and lighter than a 1" with comparable torque!
And so much nicer not to have to drag a air hose around!

a lot of problem breaking loose lugnuts is the spring flex from extensions. Go to 1" drive and those extensions dont act like springs. I would just get 1" breaker bar, extension, and sockets just for the wheel removal. Usually this difficulty is only when wheels havent been removed for years. Rent the big stuff?

BK has a point as far as portability in the battery tool. That CP looks different than ours. We've been using our Chicago Pneumatic for 3 decades so we're partial to it & it surely doesn't hesitate to loosen stubborns. We use black steel impact extensions because standard extensions reduces the effective shock of impacts & sockets too (impact vs standard) for that matter...

Busnut  tool duty is pretty light...

In 10 years... the air tool will still work just fine.

The battery powered tool?

Maybe old school is enough?

Happy coaching!

BW 10-4 on old school! That's how we originally did it & still can if need be. Always carry the 6' x 1-1/4" cheater!

I carry a torque multiplier for changing tires on the road.  They definitely get the lug nuts off but I don't trust them for tightening to a set torque so would plan to stop as soon as possible at a truck tire shop to get the lugs properly torqued.  I tried marking the lugs and wheel when the lugs were at spec and then removing (counting revolutions).  I then reversed the procedure using the torque multiplier to tighten to my marks.  The result was off (loose) by about 25 ft lbs at 325 ft lbs.
Good enough to get to town but not good enough.

I'd love to have a 1" torque wrench but just can't bring myself to buy one for such a limited need.  Jack

We have a 3/4" torque wrench good to 600 ft lbs & a 4 to 1 torque multiplier but don't carry it on the bus. We have developed a pretty good "feel" with the 3/4" air impact.

I like Delo 100

This spring I installed new brake drums and shoes on my drive's and the guy that helps me is a heavy truck mechanic and he brought in his Milwaukee impact gun not sure what model but because he uses it at work I am sure it is the most powerful gun they have .
We used it on 3 nuts then it would not do any more so for me I would stick with a air impact 3/4 " or 1" ( 1200 foot pounds or more ) so you know it will always work

Ok I'm a Milwaukee guy so let me clear this up.

Milwaukee makes 3 different high torque impacts, each designed for a different use and each one has progressively higher torque. I'll post three screenshots that include the torque info and a pic of the machine.

I have the smallest impact shown here, it does good on lug nuts considering it's only a 1/2" drive
Smallest to biggest in order

I have a Milwaukee 1/2 drive it doesn't have much hang time and has been replaced twice,I have aa I/R from the 60's and a MAC both 1/2 inch drives they work every day and just require a few drops of oil,lol to much impact wrench will have you buying good drill bits and taps   

[chessie4905]

I've  seen pictures of Milwaukee nose pieces that split or shattered, probably from trying to loosen nuts that wouldn't loosen. I think once you get them loosened and cleaned and properly retorqued, most 3/4 electric will suffice. Or break loose with big bar first.
