Title: Impact Wrench Q
Post by: arai_speed on July 13, 2010, 09:05:26 AM
So I'm looking to buy an electric impact wrench for the joyous task of removing the rear wheel and the 1000ft/lb of torque at which is screwed on.

I read the Kawasaki impact wrench can do the job:

http://www.amazon.com/Kawasaki-840017-2-Inch-Impact-Wrench/dp/B000EOJGNO/ref=sr_1_26?ie=UTF8&s=automotive&qid=1279041973&sr=8-26 (http://www.amazon.com/Kawasaki-840017-2-Inch-Impact-Wrench/dp/B000EOJGNO/ref=sr_1_26?ie=UTF8&s=automotive&qid=1279041973&sr=8-26)

Any feedback on this model or others that you've used with good results?

I don't have an air-compressor so I am ruling out any air-guns.

220 should be more than enough.

if u look into other options, wall plug in is the only way to go.

i have a cheap campbell hausfeled 250lb one and it takes that nut of with ease.

 [roll]  My $900 MacTools 3/4 drive air impact won't put out 1000 ftlbs.

  The best electric probably puts out around 185 ftlbs. No matter what they say it's rated at.  110 volt plug in.

Ha...I was joking about the rear nut being torqued to 1000ftlbs...it sure feels that way but I know that is not the case  ;)

I bought a cheapish 320Nm electric Ozito impact wrench from my local hardware store.  Spins it off like your 1000ftlbs was finger tightened by your Granny  [thumbsup].

I have that exact impact wrench (got it for the same reason).
Well built, works like a charm, highly recommended.
You will think back to those times when you and two friends stood on a four foot breaker bar and want to kick yourself!
BTW, you will need to also buy an impact socket to fit the massive wheel nut.

I am a cheap bastard.  Bought a $50 1/2 impact wrench from Harbour Freight.  Taking off the rear wheel nut was a breeze.  I also used the impact wrench to put it back on and then torqued to spec.

I have the same one and have used it for about 5 years now.  It easily makes 200-225 ft lbs, which I've confirmed.  I have a bunch of air tools too, but until I get one of those permanent tanks installed, I always pull out the electric one.

Im going to be guilty of doing this, but i run it on low pressure and stop before it even begins to get tighten. It would be just enough to get most of the screw in, then i swtich to hand tools to tigthen it and torque it.

Same here.  I have gotten very good at "feeling" the torque, but I always final tighten with a wrench.

I have considered buying a set of those torque limiting kits, but i think they only go up to like 175 or 200 ftlbs.. (edit...150ftlbs)

for almost everything hex key wise, i use this

(http://www.impresstools.com/Product-Large/BTD140ZW.jpg)

if i you let it rattle once, it does about 5ft-lbs on an m6 and if you get good at it its pretty repeatable and i do things really quickly with it. i stoped used hex keys for a lot of things.


those torque limiting extentions are cool, but what would you use it on? they are 65 ft-lbs+  if i could set my impact driver gun to slip at increments of 5, i would be using it to tighten EVERYTHING....maybe i should invent some type of clutch impact driver that does that...

Got home last night...plugged in my impact wrench and started wrenching away and NADA! ZIP! NOTHING the make the beast with two backsen thing won't budge.  I tried using silicone spray, tapped the nut w/a mallet, waited, tried again same results.

Should I concede defeat? Anything else I can try?
Title: Re: Impact Wrench Q
Post by: arai_speed on July 15, 2010, 10:20:15 AM
I called my local DucaPrialliaAgustaGuzzi dealer and they quoted me $20 to mount balance a tire if I take the wheel or $59+tax if the wheel is on the bike.  I guess the extra $40+ is for the use of a lift and their shop time  :-\

So should I buy a huge 9ft breaker bar?  [bang]
Title: Re: Impact Wrench Q
Post by: He Man on July 15, 2010, 11:30:38 AM
9 ft? who the make the beast with two backs sells a breaker bar thats NINE make the beast with two backsing feet.

are you sure the thing is going the right way?
how are you keeping the wheel from moving? (in gear? on the floor? with the brake lever?)

Maybe kawasaki brand just sucks, ive used the northen tool one and it works fine
Title: Re: Impact Wrench Q
Post by: arai_speed on July 15, 2010, 12:32:01 PM
I was kidding about the 9ft breaker bar   :)

I'm sure I'm going the right way  I checked.

The rear wheel is on the floor.  I didn't buy the Kawasaki wrench, I got the one from Harbor Freight.  The unit seems to spin just fine...except when it's in place to remove the nut.  :-\
Title: Re: Impact Wrench Q
Post by: ungeheuer on July 15, 2010, 01:39:33 PM
If you're absolutely sure that your impact wrench is attempting to reverse the nut off and not trying to ram it further on.... then it beats me.  Even with the bike on a rear wheel stand with the rear wheel free to turn, mine spins the nut off so fast it almost seems like a waste of time getting the wrench out of its box (until you try to do it the hard way). 
Title: Re: Impact Wrench Q
Post by: He Man on July 15, 2010, 02:13:49 PM
theres your problem its a  harbor freight. its probably defective. they are pretty good with returns just call them up for anotherone.

Northern tools dispite also being a discount tool store is actually not that bad.

Nitrocat 1000tc
1000ft/lb max output.

This WILL take the nut off.  You need a compressor thoough.
That being said, I've had good luck with the dewalt electric impact for taking off alternator pulleys and such.

I ended up taking the bike to the dealer - in a way it worked out as they noticed the clutch was grabbing and they were able to bleed and adjust the system in a way that I had never been able to.   So now a new tire and a nice soft easy pulling clutch made for a good sunday ride.

I will return my HB tool and look into buying a better one much later.

Thanks for all the tips.

 Buy an inexpensive used air compressor local. You can use it for other things also. Then get a good american made air impact. You won't regret it.
I've had mine for 30 years.

I will add this...

When I took my wheel off the first time I almost admitted defeat.  I used a Husky air impact rated at 500ft# and it didn't budge the nut.  I ended up using a breaker bar and a 5lb sledge hammer. Whacking the shit out of it finally got it to move.

Installation was greased threads and a proper torque.

I think it makes a difference if you're using tools, be they pneumatic or simple hand tools, every day for your living or just weekends as to how much you're willing to spend.

Perceived value is everything.

Not much of anything is made here any more...but that is a completely different topic.

Post by: 64duc on July 20, 2010, 06:34:06 AM
 I'm not really sure if anyone makes an air impact in this country anymore, partly since I've been retired for 3 years now. If anyone does it will probably be one of the major tool brands (Mac, Matco, maybe even K&D or Ingersol Rand) read expensive. Educated guess $200 to $400 range. There ain't no free lunch. Generally you get what you pay for. I'm a CB (cheap bastard) so I have found some good inexpensive hand tools over the years.

 I was a shade tree mechanic until I was 34 then started working in the rental equipment business. 30 years there.
Title: Re: Impact Wrench Q
Post by: ducatiz on July 20, 2010, 08:09:25 AM
I totally agree about the older US-made tools -- I have several sets of Craftsman and Matco sockets and spanners and they are phenomenal.  I also have a 20+ yo Devilbiss spray gun and still have no problem getting parts for it.

Unfortunately, most of the big names are importing assemblies, using min-wage labor to put them together and stamping them MADE IN USA (and in small letters "of foreign made components" etc).  I gave up.

Plus, when the CHinese and Indian factories start getting ISO certification and quality has come up while prices are still so low, you have to take notice.

$35 and it's run 6 years so far.  I bet it will crank out another 5-6 years.  If it poops out before then, who cares?

I know this thread is a couple months old but I have to add something to this discussion

I was trying to remove some shock bolts off my SV with absolutely no luck with my Husky pneumatic.  Having it chatter away with no luck budging the nuts.  My compressor puts out plenty cfm.

I gave up and went to the store and bought a Dewalt 1/2" corded impact. Came home and plugged it in and hit the bolts/nuts. Twenty seconds later I was all done!  I went over to the S2R and tried the rear wheel nut. That came off like it was hand tight.

I guess you do get what you pay for when it comes to impacts.
