327 harmonic dampner NO THREADS ON CRANK!

[Rrumbler]

DON'T HAMMER IT ON!!!! You will wreck your engine.

It is a press fit. The inside of the crank "snout" should be threaded, and the balancer is installed with a special tool. If you don't have one, and can not find someone to loan you one, you can get by with a "shadetree" tool: get a bolt that will screw into the snout, I think it is 1/2 inch, about five or six inches long, a nut for it, and two large flat washers that fit it. Grease the threads, run the nut onto the bolt all the way to the head, put grease between the washers, and put them onto the bolt. Line the keyway in the balancer up with the key - it should start onto the snout just far enough to line up right - insert the bolt into the snout through the balancer, and run the nut and washers up against the face of the balancer. Then, using a box end wrench, screw the nut down so that it presses the balancer on. When the balancer is seated, remove the bolt and washers.

I've never seen a Chevy crank that was not threaded inside; I sure don't know it all, but I have four of them around here, and they are all threaded; a 283, a 327, and two 350's. I may be all wet here; I take my crow with a side of hot beans, thank you very much.
