Install harmonic balancer.

Alright, I'm in the process of building a chevy 350 and I just pulled the harmonic balancer off so i could get at the cam. The problem is that the are no threads in the end of the crank to get the balancer back on... How can i get it back on without drilling and tapping a hole in the crank?

You can rent a tool to put it back on. If your luck is like mine you can also put it in the oven. I broke the tool so I just put the harmonic balancer in the oven 250 degrees for 20 min. It slipped right on.

post removed.

Never seen a balancer even at my age that didn't have a balancer bolt.

Learn something new every day I guess.

Must be an early 350 to not have threaded crank. As far as i know a block of wood and a hammer is your tool.

well the first 2 guys must not have read what i said. There is NOT a threaded hole in the crank. So i just put the wood between the hammer and balancer and hit it in? sounds like it will damage the crank...

Probably wouldn't be any worse than bangin' on the front and rear of the crank with a BFH to seat the thrust bearing. You do seat the thrust bearing when you put a motor together don't you?
budmclovin has the best answer for you. Heat it and it will slide right on.

If any of you guys are going to bang on the damper, put a block of wood on the center hub and beat on the wood. Don't beat on the inertia ring of the damper.

Crank is pretty strong. The interference should only be .003-.006 so it should go back on pretty easy. I should have said that you need to use a good lube on the crank snout and on the balancer. I use cam lube. I still dont like not having a positive retention of the balancer/pulley, but Chev did that for a number of years (1955-1969) and the balancers only flew off occasionally. For real hipo use, you might consider drilling and tapping the crank snout. Its not that hard it the crank is out and can be put in a drill press. i dont like doing it freehand anymore. Also, some crank snouts seem to be through hardened and are a pain to drill, mush less tap.

Motor turns clockwise lookin' at the crank snout. Use a LH tap. Crank the motor and let it idle. Push the tap into the hole and hold on. It'll thread itself down to the end of the hole in a hurry. Use a LH threaded bolt to retain the damper. Just kidding, just kidding.

For future reference, there's no need to post the same question TWICE.

It might not have even been your fault- if the server "hiccoughs", you can enter a post more than once thinking it didn't "take" the first time. Sorry if I sounded like a post cop, or an *******.

If it's possible, would you post the suffix code from the pad located on the passenger side of the front of the block, where the cylinder head meets the block? I'd be interested to know what car had this engine in it.

Thanks.

Just warm it up and it will slip right on. Use a toaster oven or a regular oven. Dont try to torch it or you will eitehr weaken or destroy it.
