JONESER if you are popping sockets, either the sockets are crap, or you are applying too much torque too fast. Either use a breaker bar and gently bounce on it to break the bolt free, or stand on the bar and tap the socket with a hammer to loosen the bolt.

BTDT. Ended up going to a 3/4" drive and socket. That thing has gotten passed around a few times.

Re: Impact Wrench to Remove Crank Pulley Bolt?
I recently replaced the timing belt on my '05 Accord 3L V6. I had a three foot extension on a 2 foot breaker bar, with the hex holder wedged on the floor and still the bolt wouldn't budge. I was concerned about putting a torch to it and frankly couldn't see how expanding the bolt would do it in spite of testimonies that it will. It seemed that the answer was to freeze and contract it. So I tried spraying a small shot of liquid R-134A on the bolt. Probably less than one ounce of the stuff and then put the breaker bar on it. It came loose right away with only half the torque I'd been putting on it before. Releasing even a small amount of refrigerant like this would not be permitted in a commercial shop, mind you.

Re: Impact Wrench to Remove Crank Pulley Bolt?
Has anyone tried the "heavy" (Lisle, and a few others) weighted 19MM socket? There are physics majors in other forums theorizing why that works...but a couple of videos on YouTube are pretty persuasive. For fun, in advance of my attacking the J30a1, I 'bulked-up' my 19MM with another pound of lead wrapped around it; we will see if the torque is better transferred to the bolt this way.
Stay tuned.
Stay tuned.

Ive taken off dozens of Honda crank bolts with it,using nothing more than a regular 1/2in impact(IR)
*** Im talking about the Lisle socket. Ive never used any other***

Good deal. I'll have the partz by the weekend, and share back my results of the poorman's Lisle, thereafter.
'Love the starter-bump idea, too; I'd completely forgotten that little trick from back-in-the-day. Seems that OEM starters are rated in the 200 #-ft range, but there may be gear-reduction magic that improves that. And, it's hard to beat for "pucker factor"!

so I can't be sure it will work, it might, it might not

I do it the simple way..shove a piece of vacuum hose down the cylinder with the piston semi down and just use this to lock up the engine...after bolt breaks loose back engine up a little and remove hose..done

Re: Impact Wrench to Remove Crank Pulley Bolt?
sure..once you have engine timed on #1 cylinder you remove the spark plug..using the crank bolt move the crank clockwise around 1/2 turn..now #1 cylinder piston has ropm to shove the hose in..feed as much as you can in..i use a screwdriver to cram it in..now using the crank bolt again rotate the engine counterclockwise and the piston will come up and lock the engine because its compressing the vacuum hose..using a extension to get past the fender and a jackstand to rest the extension plus a breaker bar..fence post..anything to get leverage..you can now break the bolt loose..just back engine clockwise a touch and remove hose..set back to #1 tdc..Done..keeps you from having to buy crank holder tool..THIS WILL NOT HURT YOUR ENGINE..done it too many time to count..

Re: Impact Wrench to Remove Crank Pulley Bolt? (wadded hose trick)
Ingenious; a rubber-stopper against which the piston can safely mash! This cheapskate will be using that tactic, if the lead-laden impact socket doesn't make it yield.
While I generally welcome the "excuse" to buy tools, having to buy a specialty holder - not to be used again for several years - is pretty hard to justify. Thx for sharing that tip!

Re: Impact Wrench to Remove Crank Pulley Bolt?
I use it all the time..especially in the junk yard to remove drive plates..flywheels..etc..i usually just ****** off some vacuum hose and stuff it in a cylinder..when i do timing belts on Honda's it works everytime..

You know - 'not to beat this notion to death, but - in concert with the "safe cylinder block" approach above, another trick (from frozen wheel lugs) comes to mind:
With CARE, (using your "good" floor jack...the one you can control easily) raise the car up sufficiently to wedge the cheater bar in the correct orientation, then lower it back down such that the weight of the car does the work. I have used this on rusted lug nuts, and with a gentle lowering to effect the desired CCW rotation; a ton+gravity beats sore muscles and hernias every time.
Man, I love this board. It only lacks having a beer at the bar while sharing - 'maybe someday with virtual-reality ;-)

Re: Impact Wrench to Remove Crank Pulley Bolt?
I bought the holding tool, got a couple big breaker bars & I have broken 4 sockets already! One Craftsmen, one impact socket & two that were rusty... LOL
Seriously though, I'm getting pretty pissed that I cant get this thing loose. I have to go buy a new impact socket now & I swear that if it breaks, I'm breaking windows or something!! Anyone suggest a certain socket or somewhere that has a strong socket? Harbor Freight?
