Crank Pulley bolt woes-HELP

[135pinebob]

hi-i am trying to replace the timing belt on my 91 civic wagovan. I am at the point where i am trying to remove the 17mm bolt which holds the crank pulley on. I have had 2 impact wrenches on it, several breaker bars and hammers, and i cannot break it loose. My questions are 1) is this a conventional thread which tightens clockwise and loosens counterclockwise,(i have been trying to loosen counterclockwise)- and 2) I am afraid of breaking motor mounts and exhaust couplings by placing so much torque on this. i would appreciate any ideas and advice from any of you out there who have done this-thanks alot-bob

Try heating it with a blow torch first to get it red hot, then poor water on it, then try cracking it again. If the flywheel is turning, then take the starter off and take a prybar and put it in the pressure plate hole to stop it from spinning (most time consuming, but easiest if you didn't loosen the bolt while the tires are on the ground). If you have a air pressure tank then go buy an ingersol rand impact gun, use it, return it. Or get a 6 foot pole and find the fattest person you can possibly fit into your garage to bounce on it. You will have to support the extension, or get a jack stand to support it and try it yourself. That bolt is SOB especially the older your car b/c the crank tightens the bolt because its going in the opposite direction. Your spinning it right too.

thanks for the response DJ. i have an ingersoll rand impact gun and also borrowed a mac-i ran them at 90psi after soaking with pb blaster-i tried this repeatedly for an hour-no luck. i have the pulley chained so it does not turn, and also put a breaker bar on it and hit it with 2 sledge hammers-no luck. i also put a breaker bar on it and pushed at it with both feet-no luck. i worked on air cooled vws for most of my adult life(i am 56) and had to deal with a 36mm gland nut which holds the flywheel on and is torqued to 300+ ft lbs and never had this much trouble. does honda have a special tool for this or is there a special tool on the market for this-thanks alot-bob

I know some honda crank pulley bolts come out pretty easy with a special tool. I dont know the name of it, but it looks like a huge bolt, which connects onto the crank pulley and the center is open allowing you to break the nut loose. (crank pulley tool/nut...you may find it at sears) The tool requires you tool add an extension of some sort so you will have enough leverage to crack the nut. But seriously, find someone else to help you crack the nut off. It always takes 2 or 3 of to loosen that damn thing. I've never used the chain, b/c I was always concerned with knicking the pulley. Just get a long breaker bar, add a pole to that, and bounce on it.

thanks again for the reply DJ-i will try what you said and i am also going to try a 3/4 inch impact gun on a larger compressor-regards bob

i tried everything to remove my pully in thew process i bet it up so what i done was haul the grinder out. Your going to hate me for this, i cut the pulley out till i could get a wrench on it then i kept the car in gear and kept hitting it with a hammer till it POPPED !!

I'm sorry...do you live somewhere that has no car mechanics?

That was a joke, but seriously now....did you at any point think to just call a mechanic? Honda Dealership? The two tooth wonder who can fix anything with wheel at the local corner filling station???
