ok so i have a b18b with a seized crank pulley bolt. I have tried multiple different things ive tried air guns, breaker bars, breaker bars with pipes on the end. I am about to try my 1600 ft/lb impact gun. I was wondering if anyone has had this problem if so.... or if not maybe leave some ideas?

 

Yeah, sometimes my 680 ft/lb impact is needed cause my 400 ft/lb can't get her done.

 

I'd suggest you try this before doing something that could snap it. It would be a pain to deal with, since its a very uncommon metric size tap needed to fix it.

Find someone with a junk oven (craigslist.org?) or clean the crank extrodinarily good & use your own, heat to 400F+. Then use a bottle of C02 (air duster cans) to blow on the bolt to cool it down. The goal is to get the crank expanded and shrink the bolt. Just don't use an impact on a sub-zero bolt, it is easier to crack at that temp. Try the breaker bar again before the impact.

They are usually put on w/o oil at 130+ lbs, so its not hard for them to lock up.

 

Well its good to see that other people have had this problem. Anymore idea's?

 

Try to tighten it with the impact then try to loosen it. This may take several times to work but its saved my *** many times. Good luck.

 

I have tried but only once, maybe will have more luck eventually

 

bump for more ideas.....?

 

PB Blaster or WD-40 since nobody else said it . I know at the Acura shop where I work they use a big socket that fits inside the pulley and a four foot breaker bar with a socket for the bolt to break it loose. Sometimes it takes more than one guy to get it loose too. Major major PITA.

 

thanks for the idea breaker bars are just not working for me....?

 

i say your impact gun is just not strong enough, when i worked at a shop we had 1 impact gun, it was a beast, we only used it for crank pulleys cause none of the other guns would work.

 

you now the ft/lbs on that gun probably 600 or something?

no, i dunno what it is, but i used it on a lugnut one time and it ripped lug out of the hub and shredded the stud boss was very angry with me

 

i would use heat before i tried the pb blaster. do you have the flywheel locked in good so its not spinning the motor at all?

 

I took the flywheel off. When i went to put it on the engine stand.

 

i have a 3.5 foot pipe that i put over the end of my breaker bar for things like this

 

use a good acetalyne torch and heat the bolt till its near red, then stop right away and hit it with the impact. it will come out if u do it right. it may melt the timin cover a tad if heat transfers fast but if u dont heat it u may snap it off . especially using a big breaker bar then u need a new crank.

 

thanks guys i think im going to try heat... i willl let ya know what worked for me

did the heat work? I made a Crank pulley tool out of a pipe nipple... I am doing a write up about it now... ill post the link when im done...

 

i havent had time been real busy but, if you would post that link would be great. i was thinking of making that tool also. so any ideas on how to would be great. i am pretty sure i could do it just seeing other peoples work sometimes helps.

how big is your breaker bar i used about a 12 ft breaker bar lol no joke it was a pole that holds the street signs my pops had some laying around the house and i put that on the ratchet and hung on that thing for my life and all i heard was a loud *** POP i thought i had broken an extension or the ratchet but just broke the bolt loose worked great expletive the air tools they didnt work for me

 

I bought a tool from honda that fits in the end of the crank pulley. It has a handle with a big nut welded on the end of it to keep the pulley from rotating. Then just like everyone else said get some leverage (but i think you have the motor out so I don't thing it going to be easy since it going to move all around)

 

spray deap creep on the bolt every hour for about 5 hours, the let it sit over night. Then take a torch to it and a breaker bar should get it off.

 

holding the motor is not that big of an issue, and yes it is out of the car

 

Update: so after the motor has been sitting since i started this thread. I have been slammin on the bolt with air guns and breakerbars trying to break it loose. But yesterday went at it with a breakerbar and hardly put any tension on the bolt and it broke free. I am assuming this is because of me messing with it and it sitting in the heated garage. Not sure i have one more to do that wont budge. I guess i will try this let it sit around trick since im not in any hurry. But wanted to say thanks to anyone that gave input.
