So….this bolt is a son of a bitch.



Even this has not worked. Any ideas are welcome. Thanks.

 

Fence pipe cheater bar over 1/2" breaker & 19mm deep socket was my goto for many years. Bear in mind, you need to stack up some long 1/2" drive extensions to get the cheater bar past the fender. And another bar connected to honda/acura holding tool close to the pulley.

On tough ones I use the starter bump method. You can find several videos online. Just make sure you have everything braced in and tied back so that nothing gets flung out. Keep everyone away when you crank the car. It should just take a short burst and it will come off. Use a 1/2" diameter breaker bar or bigger, do not use a ratchet, it will most likely ruin it. You DON"T want the car to start! You can disconnect the connectors on the coil packs to ensure it doesn't start.
This is dangerous, so take all precautions before you do this, only do this if you are comfortable with the method. Just keep away from the wheel well and breaker bar when doing this.
I once cracked apart a 19mm impact socket using this method. Torque is dangerous!

There are other videos check out a few before doing this.

 

Ive attempted this and did indeed crack a 19mm socket and the dang bolt didnt budge

 

I have never had one that failed to come off using this method. I did use it my Acura and it worked after a couple of attempts and a big dent in the oil filter. Really had to tie down the breaker bar. I also tried the fence post extension first and then 6 feet of galvanized steel pipe and I only succeeded in bending the 1/2" breaker bar. I now have a really heavy duty 19mm socket just for these bolts.

 

ordered this…

 

I only have a few 1" tools as I haven't had to work on any large trucks. I hope this works out. Let us know what winds up working for you and good luck.

 

this is a must. I’ve done two jobs with this and the bolt came off within 4 seconds using a Dewalt DCF889

 

Maybe I'm just lucky being in AZ. We don't get the rust and corrosion that many other states do.

I now use a 24V 1/2" impact from Lowes, which i've only charged 1x in the last year. Takes those bolts off no problem.

That socket does look nice tho.

 

I have the heavy socket made for honda harmonic balancers, I think it’s from snap on or Matco spins the bolts easy

 

Used the crank car method, worked fine with a thick 19mm bolt off Amazon

 

It's still wild that the 1" impact monster didn't work.
