    This Proform Engine Crank Rotator Adaptor easily attaches to the balancer and is very useful when assembling an engine or degreeing the cam. It allows the crankshaft to be rotated with a 1/2" breaker bar or a 1" socket and breaker bar (Not Included). This adapter fits both Chevy and Ford V8's.

    66782 is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from This is a simple tool that gets the job done. It bolts on easily and provides a nice one inch hex to turn the engine with a socket wrench or beaker bar.

    Rated 3 out of 5 by from Not for all Chevy V8's Sadly I found out the hard way that this Rotator Adaptor will NOT work on 1955 - 1957 Chevy 265 V8's. Hole patterns do not line up, no matter which way you flip it. These are the Harmonic Balancers that have an attached RIVETED Pulley. However it does fit my 1958 Chevy 283 V8 which is good. Looks like it will fit all Chevy V8 Harmonic Balancers with BOLT ON belt pulleys. Guess I should have called Jegs Tech and checked first before buying it for my current V8 project. However I am happy I bought it as I can use it for 1958 and later V8's. Product is very reasonably priced.
