Somehow we have gotten away from the topic. Without being familiar with a counterweight assembly, it is hard to comprehend what it actually is. My question was not how to save the old crank. I have 5 years working in a parts house with machine shop, and 20 years in trucking while doing most all my own repairs, and hobbyist of Hot Rods building several race motors, and general motorhead.
The old crank is not to be saved. The new engine's crank does not have the gear built into the throw of the second journal that drives the counterweight assembly which is actually mounted inside the deep oil pan below the crankshaft.
I do appreciate everyone's input and I am familiar with the methods mentioned. The new engine is already purchased, zero hour, surplus engine, so my only concern is, if anyone else had incountered this, what should I be on the lookout for ? Thanks Again
