    flywheel locking

    How do you lock the flywheel? (Auto doing cam swap) On the how to they say to use a screw driver. How do you get the screw in there to hold it in place? Does autozone or any of the big name stores loan out a fly wheel locker?

    They mean, stick the screw driver into the teeth, & up against the block to keep it from turning. I don't see why you would need to lock it for a cam swap. If you do, you need two people. Just use a 1/2" air gun to get the crank bolt loose.

    I always pull the starter off, and access the flywheel that way to lock it in place.

    Are you trying to pull the crank pulley?

    if so go to orielly's and rent a Chrysler harmonic puller or rent a 7ton puller. The chrsyler goes on the inner 3 tabs and the 7 ton goes around the whole pulley, they both will work to get it off.

    also you may have to use a bolt and washer to stick in the crank shaft with a smaller diameter than the hole in the pulley to get the puller bolt to actually press against something.

    GMHTP recently had a pic of a small prybar shoved through a hole in the passenger side "subframe" that they used to lock the engine.
