What should I do. I just payed $260 for an IR 1000 ft/lbs impact wrench and the damn thing won't budge.

 

You need a crank pulley wrench. It is also called Honda Harmonic Damper Pulley Holding Tool. Check this site: http://www.thetoolwarehouse.net/shop/TTW419. We tried with air tool up to 200 lbs and it would not budge.

You have to jam the holding tool with an extension 2-3 feet up against the lower control arm. Also, use a air tool 19mm socket and a 3 feet + cheater pipe over the extension. Otherwise, you will never get it off.

 

Try this trick: Alternate the gun rapidly between loosening and tightening the bolt.
After a few tries it should loosen up. I use this trick at the dealership with a Craftsman 1/2 gun and have yet to find a bolt that won't come out.

 

nice trick with the gun! i'll have to try that at the tire shop rather than cracking sockets (i don't pay for them lol)!!!

 

Well if they're quality tools..they should have a free replacement .

If you bore out the bottem of the valve where the hose connects, you get more airflow which sometimes may work also. Make sure you do it to the inlet size of the hose also.

 

Thanks-I'll try that technique. Is it the thread-lock that is putting up a fight?

It shouldn't have thread lock on it, they just tight.

 

ok good to know-thanks. I'm really gonna be pissed if this 1000 ft/lbs impact wrench doesn't do the trick.

 

It will- use the alternating method, as stated above. Throw a little heat in the mix also. My buddy uses 1000ft/lb on big diesal machinery-

 

Grab up your favorite flavor of air tool oil, hold open the trigger of the impact and squirt in a couple ounces. Then hook up the air line and get on the crank bolt, pull the trigger and zing that jewel outathere! Be prepared for the oil spray from the impact.

 

I wish it was that easy. I've tried many times with the 1000 ft/lbs IR impact and nothing. I even tried the technique of forward, reverse, forward, reverse....... (and soaked with PB Blaster)

 

we have never had a problem getting one off, fwd and reverse it will come off in a few minutes with a IR impact

 

It's soaked in PB blaster and we tried forward and reverse even tried extra PSI to the impact wrench....NOTHING WORKS!!!! The impact wrench is this one: http://www.sjdiscounttools.com/ir2135ti.html

 

what kind fo compressor do you have that hooked up to? that could be the problem....just because you have a 1000ft/lb IR does not mean that that thing is putting out 1000ft/lb. how much SCFM does your compressor put out? what size is the hose that feeds into the gun? you might not have enough juice comming from the compressor to power the Ir to its full potential.

 

Yea That is the problem i realized earlier today. My compressor puts out only 5.1 scfm at 90 PSI so the IR isn't getting enough air. I'm gonna have a garage break the nut loose and tighten it down so I can do the rest on my own.

 

so what is needed in regards to scfm to power the gun? or what is a number that is sufficient enough?

 

I don't know but I'm sure a shop can crack the damn thing loose. I'm just hoping they'll do it for free or of low charge.

 

I'll tell you how I did mine.

I jammed a small crow bar into the flywheel first.

Then got a breaker bar and a 3 foot steel hollow pipe. Put the pipe over the breaker bar and leaned down on it.

One reason air tools can sometimes be ineffective is because they just smack at the bolt with all their force with one quick impact. You need a good long yank on that sucker. We had it off in about 2 minutes.

 

I've done it by hand 2-3 times with not too long of a breaker bar.

This one hurt....

.....the sound was the gears in the 1/2'' Craftsman going bye bye.

 

ouch-looks like that did hurt a lot. Just looking at my hands and arms right now, i see all sorts of cuts and dings from working on my car, but it beats paying ***-loads of $$ to the shops. I guess I'll return that IR impact wrench and get my $275 back (which i could get for $100 less on ebay) and try jamming a pry-bar in the flywheel.

 

isnt the crank pulley reverse threaded like the power steering pulley bolt ?? is reverse threaded because the pulley moves one way only.. and instead of having it be a threat of loosening its reverse threaded so it would always be being tightened!!! just thought u might be going the wrong way d00d.. but i could be wrong

 

Yes you are definitely wrong.

When/If you do get it off, manual tells you to coat the thread in oil before reintalling to prevent it from being so hard to get off next time.

 

Yea I think it's normal thread, not reverse, but thanks for the suggestion. I broke 2 breaker bars and 3 craftsman ratchets when doing my rotors (on the spindle nuts) I'm sure it'll happen on the crank bolt too, but it's worth a try.

 

well once you have the shop to zap it off...then what? are you gonna have the car towed back to your house? if you tq it down again and drive on it it will just retighten and be a bitch to get off again...im just about to do mine too. I have a 93 lx coupe with 150K on it and i am not lookign forward to trying to get it loose.

let me knwo what you decide to do...i could really use the help. i was going to rent a heavy duty compressor and gun...but im just not sure how much cfm is needed or how much tq....

 

I've done that a couple times. Have the shop take it off, then put it back on but not real hard. I drove about 1 mile back home, then it came off OK.
