According to the shop manual one must use the puller and a special threaded bayonet nut that fits in the crank hole. I guess it draws the puller main screw in pulling the balanacer back on the crank? Is this right? The shop manual says any other way will damage the balancer. Is there a work around?

The instructions in the 1939 manual are very confusing.Note that the last paragraph pertains to installing the balancer with the puller.
To remove just use any present day balancer puller.To install a large hammer and drive it on.Best to insert two cap screws in the puller holes when installing to prevent damage.Pound only on the inner surface.I place a large short piece of pipe around the center crank adapter and pound on the pipe.

Any bit of mechanics work that involves a large hammer is always fun.

When driving the harmonic balancer on with a hammer, doesn't it put a lot of pressure (shock load) on the main bearing shoulder that limits the linear movement of the crank ?? Can the bearing be damaged ? Is there any practical way to back up the opposite end of the crank, to remove the shock load from the maiun bearing?
I've always hammered mine on, with no apparent ill affects, but it always seemed kind of a primitive way to do it. Any thoughts on it?

It's a scary thought for the crank and the balancer which is basically almost impossible to buy. Chevgene's pipe strategy sounds like it should work as long as I know when to stop hammering.

You will know when to stop hammering by the sound of the inpact of the hammer hitting the balancer/pipe.This method was used millions of times and never caused a problem AS LONG AS THE OUTTER RING OF THE BALANCER WAS NOT STRUCK.Most pounded directly on the inner part of the balancer.It goes back on easier than you think...If you need a new crankshaft I have a spare. :eek:

Some where along the line I have read that putting the balancer in the oven and heating it will help. I do not recall how long or how hot but there must be something in the archives on this.
