Crankshaft pulley puller tool

    I am in the process of replacing the timing belt, drive belts, and water pump on my 86 GT (2-SE engine) and I have hit a problem-- I need some kind of special tool to remove the crankshaft pulley (to hold it in place while I remove the bolt). I have tried makeshift setups, but they always break or bend from the huge amount of torque I have to give it.

    Does anyone know where I can get a tool to remove this myself? I can't really afford to have it towed to a mechanic's shop.

    Also, just to make sure... I don't need any other special tools do I???

    You can use an impact gun to get the bolt off. I have done it by holding the flywheel with a pry bar. But you do need a pully puller to get that off of the crank shaft.

    I have a normal pulley puller so that's covered... but I tried getting it off with an impact wrench earlier and it didn't move the bolt at all. It's on there really tight...

    What I did was took a pry bar in the hole were the starter is suppose to be and had someone wedge it in there. The I took a socket with a breaker bar. On the end of the breaker bad you get like a good 2 feet of pipe. Or you can take a deep socket with a couple 10" extentions on it. That gave me enough leverage to break it free.

    I wouldnt use a prybar...you run the risk of damaging the harmonic balancer. Pullers are cheap and if your near an autozone or advance they have that loan-a-tool service.

    well if nothing else works.....ie. impact gun/heat. I would wedge a breaker bar against the ground and kick the starter over a couple times (disconnect the coil wire first so it doesn't actually start). Make sure it is wedged in a way that the bolt will spin correctly....you do not want to have this backwards. But do this only as a last resort cuz 3 things can happen here:

    1. You snap your breaker bar. It could easily happen if it is a cheap one...no big deal go buy a better one


    2. You break the head off the bolt. Its a bigass bolt but I've seen it happen...then it needs to be drilled out and rethreaded.....not fun

    3. The bolt breaks free.....now you have to struggle with a puller and get the damn pulley off

    I fashioned together a makeshift puller today, consisting of 4 long pieces of galvanized steel bolted together with holes drilled out for the center (for the wrench) and for the two bolts... I found two bolts which fit the threads and put it all together.

    Once I applied significant pressure with the breaker bar, one of the bolts sheared off and the other came out... so I had to remove the sheared bolt (not fun) and bend the metal "tool" back into shape.

    It is ready to go for tomorrow morning... if this doesn't work I'm not sure what will, considering how much torque I was giving that bolt.

    My friend suggested that because it's on the crankshaft, the bolt could be reverse threaded... do any of you know if it is from experience or could give it a guess? I think I might try both directions tomorrow...

    Still working on it; the air wrench didn't get it off. Tomorrow I'm going to borrow a 1000 ft/lb air wrench from our mechanic... hopefully that should do the trick.

    Thanks for the help guys.

    yep... tried everything except for removing the starter and jamming the gear. My brother and I towed it there tonight, so hopefully it will be ready tomorrow morning.

    My mechanic got it off for free this morning. He offered to finish the job for $350 (labor only) but I'm poor :D.

    I'll finish it myself.
