Cant break loose crank pulley nut.

Cant break loose crank pulley nut.
I have an 02 accord LX with the f23a1 and I need to replace the timing belt tensioner. I do have the special tool in place to keep it from turning over but the nut will not break loose. I called honda and they said it is torque to 900 ft/lbs. I'm using an 1100 ingersoll-rand with my air compressor wired for 220 nd turned up to 140 psi, still nothing. Tried pb blast, map gas, still nothing. Any help would be greatly appreciated!

Re: Cant break loose crank pulley nut.
since you've got the tool, just use a long extension and a long pipe (6ft) as a breaker bar, i never have luck with air tools on that bolt, but the breaker bar works every time!

How long is the [U][extension/U] (the piece between the cheater pole and the socket). I work in a factory so I can get up to a 7 ft breaker bar, but I'll have to buy an extension.

the one in the picture is 20 inches long
also, the crank bolt is not torqued to 900 ft/lbs, not sure why anyone at Honda would give you that spec. It's torqued to 181 ft/lbs.

Use whatever drive you want. I prefer 1/2 inch.

he's asking about the extension, not the breaker bar...

Re: Cant break loose crank pulley nut.
Where did you get 181 ft/lbs from? I know for a fact its higher than that. I can't get an 1100 lb impact to break it. I first had a 320 lb torque on it and it clicked every time. 181 wouldn't need a breaker bar.

Re: Cant break loose crank pulley nut.
The reason you can't get it to break is probably because of the fact that the nut is staked.
Also, put a jack under where the ratchet meets the extension so no matter how hard you try to break it loose it's always straight on.

Re: Cant break loose crank pulley nut.
How do you know for a fact that it is higher than that? Were you the last person to tighten that bolt and crank it on there higher than 181 ft/lbs? I don't care what size impact you are using or how much torque it can deliver, that doesn't indicate what spec the nut or bolt you are trying to remove was actually torqued to.

Look it up in the service manual. It is 181 ft/lbs.

Re: Cant break loose crank pulley nut.
I used a small blowtorch to warm it up a bit. My electric impact couldn't remove it before the heat but worked right away after it. Some people might say "don't use heat" but I've put around 40,000km on it since, and nothing has broken.

if you would have taken a peek at the FAQ before posting you would have found the answer to your question anyway.

Re: Cant break loose crank pulley nut.
The 900 ft-lbs doesnt seem that ridiculous even though we know when its factory installed its probably 181 ft-lbs. Assuming no losses on a 6 ft breaker bar (not realistic), it would only take 31 lbs of force to break that crank pulley bolt loose. I can guarantee I was putting at least 100 lbs of force on the pole and it wasnt breaking loose. A more rigid breaker bar would have probably helped.

Re: Cant break loose crank pulley nut.
I have seen several videos where pros used an oxy-acetylene torch and then blasted it off with an impact. I cant believe you got it with an electric impact.

Re: Cant break loose crank pulley nut.
ive done this on my accord like yours, all by myself, no heat, no power tools, small box-o-tools, and i'm not hella strong either
pick up the car a lot higher
stick the holder on like you got there
dont use ANY extensions just straight up socket on breaker bar breaker bar should come out under the bumper, you might have to turn the motor a little so you can have the holder on the ground AND have enough ground clearance for the breaker bar
stomp/stand on the breaker bar just like you see people trying to take off a tire,
*apply the force directly 90degrees with the handle right on the tip, normally you that would hurt, but you got shoes, step on it! its about 20%more power than pulling it at an angle
*extensions kill your torque A LOT, thats why the accord torque steers so bad-its got one long *** shaft and a really stubby one
*as long as you dont shake around side to side, theres no way you're gonna tip anything over if you got the ebrake and chocks good
