Turning engine over without a harmonic balancer or flywheel?

Hi, Guys.

I've got my engine together and I was planning on bolting the flywheel to the crank flange to gain the leverage I need to turn it over to top dead center so I can then measure my deck height. Unfortunately, the flywheel that came with the engine goes to a little 4 cylinder - LMAO. And I was planning on using the harmonic balancer off of my current engine for this one.

Does anybody have any tricks to turn it over some other way? The only solution I have is to use the rubber coated end of a hammer and press down on one piston.


Thanks.

Just buy yourself a crank socket for SBC (you'll need the woodruff key for the balancer).

You can get inexpensive ones for 15 bucks.

Thanks, guys.

I can't get one locally. So, I may make one at work out of some stainless bar stock.

If the crank has a keyway with a key in it. Use a large Cresent type wrench. Adjust to shaft size and the shaft will turn when you move the wrench, as the wrench cannot pass over the key. Been doin it for over 35 years..

There is an actual flywheel device made for that Napa has them. It is a prybar with a hook device kinda like an old log peavy..you need one when installing tans as well to rotate the flywheel so the torque converter bolts line up in a convenient location..

In your case just putting the flywheel on temp may work for you..

You could use a 7/16-20 x 2-1/2" or so bolt(balancer bolt) and get a hex nut and washer to use like a jam nut. Screw the nut onto the bolt as far as it will go, put the washer on, then thread the bolt into the crank as far as it will go, then turn the nut CW until it bottoms on the crank like a jam nut.
As long as you have a long enough bolt that it will bottom out in the crank before the nut contacts it, you shouldn't have to worry about stripping the threads out of the crank.
FWIW

PS That is if your talking about a sbc.

Back in the good ole' U P of MI we called them a cant hook. I never heard the word peavey until I moved to civilization. Not sure if that was a good thing or not. They say ignorance is bliss.

This was going to be my suggestion as well.

It works well because you're not risking stripping the threads out of the crank snout and if the nut galls on the bolt you can still remove the bolt. Super simple.

This looks like the one I bought from Summit:

A little pricey but I wanted to play it safe. I stayed away from the cheap aluminum ones.
Yeah, I know there are other cheaper ways, but this worked great with a breaker bar.
