    Whats the best way to take a crank gear off a sbc crank? I tired putting apuller on there and my puller center bolt ended up snapping off. Howabout applying some heat to it?

    btw this is in an assembled engine.

    Are you replacing the gear or trying to save it?

    Replacing/removing a stock link belt timing chain crank gear: put a clean lint free rag under the crank to prevent the gear from falling into the pan. Take a good chisel (1/2" or wider will do) put it between the teeth of the gear near where the keyway on the crank is. WACK the chisel with a hammer and the gear will split in half. Done.

    If it's a double roller chain timing chain crank gear, you should be able to put a split puller on it the pull it off like this one: http://www.sears.com/shc/s/p_10153_12605_00999046000P?keyword=pulley+puller

    You need a HD Vacuum cleaner.........

    OR Use a Gear Puller.

    I used a 3 claw arm tool that comes with a centre pointed post to remove mine and it came off easy.
    A new one was going on anyways along with a cam sprocket and chain.

    It looked something like this I borrowed from my engine builder.

    That will not work if you have a steel gear. I have seen some small blocks with what looks like a plastic gear and that procedure would probably work.

    IMHO, A little heat and the proper tool will get the job dont and not damage anything.

    Suckers are powder gears and will snap in a NYM doing this! And be careful you don't break the cast crank's snout off while doing this!!

    Now, steel gears, NO!

    Pull them off!!

    ^^ and hope you don't get a nice gouge in the crank. Get the proper tool and don't be cheap about it or Murphy's Law will kick in then you'll be :whine: .

    Use a dull 1" wide cold chisel set at the side of the key-way and a 3 pound Ford tool and go.

    No problems at all and I've done in many times!
