Balancer bolt won't budge
I'm having a hard time trying to loosen the balancer bolt on my 77 350 motor. It is on a stand, heads and intake off, and I have even gone as far as putting a 4' pipe on my breaker bar, but I can't give it a full yank because it just want to tip the stand over. The motor has been appart before I ever got it and think I am in deep doodoo if someone put loctite on the bolt. Any suggestions on how to loosen the dang thing?

I typically have my shop air set at 90psi and don't usually have any problems breaking lug nuts(or just about any other nuts/bolts) loose. On the rare occasion I do, I jack it up to 110psi and it works fine.

I plan to, I just want to get a little more done first. Plus get some more pictures. I do have a little bit about it in the vintage Olds section, in the "1946 1947 and 1948 How many own them?" thread: https://classicoldsmobile.com/forums...-own-them.html

There are some incredibly smart people here.

The 110lbs is the air pressure at the gun. I can run the compressor up to about 150 or so before it shuts off, so I tried bypassing the air regulator and running my impact gun right from the compressor at 150 psi and it still wouldn't budge.

Yeah, I have an old head bolt going through the flexplate and wedged against the block and the engine stand. The crank isn't moving at all, it's just when I put too much pull on the breaker bar(with a pipe on it) it just wants to tip the stand. I am going to mount the engine in my frame and I'll be able to get more pull on it. Maybe tomorrow, we'll see how my day goes. I spent a good amount of time in the garage today because it rained all day!

I had the same issue with my engine on a stand. Impact gun, heat, hammer, nothing would break that bolt. I wound up going down to the local hardware store and bought some cheesy china brand electric impact gun that wasn't your typical gun. It kinda "spooled up" for a few seconds then gave you one powerful "WHAM!" then started spinning up again. It's actually 12v powered too believe it or not. I was VERY skeptical it would work but for $20, why not. Worked great. It would take forever to do something that needs a lot of turning, but to break something free, I've seen nothing more powerful. I'll see if I can find a link. I'd tell you the brand and store, but I'm in Japan so it probably wouldn't help much. I'm sure the States has got to have something similar.

Success! I sprayed it up good yesterday, let it sit overnight, then went at it again today. First I tried the impact gun at 150psi with no luck, then put the 4' pipe on my breaker bar and gave it a good pull and it let go. Never had one fight me so hard! Thanks for all the help, guys!

Yup, that's exactly what I did...for 2 days straight! That didn't work, so I oiled it up good with WD40 and let it sit overnight, then the next day I whacked it good a few times with my biggest ballpean hammer and hit it a few more times with the impact, then put the 4' pipe on my breaker bar and that got it.

The reason I said to make a crank holding tool is that you can pull up on the holder while pushing down on the breaker bar, so the engine wouldn't topple over on to the ground. They really help when the engine is in the car too.
