327 balancer installation--- How do I do it safely?
Permalink  

I have installed plenty of balancers over the years on 283 and 327's that don't have a drilled crankshaft. However, I hate the idea of pounding them on because of what it may be doing to crank bearings.

Has anyone ever figured out a way to install one safely without a hammer?

My one thought, crazy as it sounds is to stand the engine up on the back end on the concrete floor. At least then the crank is supported against a hard surface and it's not moving back and forth in the block with each blow of the hammer.

Here's my thoughts on it but as you know, I'm not an engine builder. I would leave the engine (crankshaft) out in the frigid Mb. air for a couple hours and heat the balancer in boiling water prior to installing and my bet is it will slide on with minimal tapping, if any. It works for press fit bearings in gearboxes on drilling rigs! We heat the bearings in hot oil and cool the shaft with propane and they slide on by hand yet need pullers to be removed. Hope it works.

I guess I could leave the engine wrapped up and put it outside for the night. I had never thought of that. If I wrap it and tie it good a night of -30 really won't hurt anything.

Guess I need to check the weather and see what's ahead. Thanks for the idea.

I would suggest the same,  only, dont get it too cold.  Extreeme cold makes things brittle.

I have done lots with the engine at room temp.  Then heat the balancer with a heat gun really really hot.  Seems to make things a lot smoother.

Also, wire wheel the crap out of the inside of the balancer and clean the groove and key-way really good too, so it slides nice.

My one fear of getting the balancer too hot is ruining the seal. I know it sees 200 or a bit more in use, but I don't want to kill the rubber part of the seal.

Thanks Dave, good suggestions.

Bearing lube, gentle tapping.

The other option I have just read about on another forum would be to drill and tap the crankshaft, then bolt and washer to pull it on as normal. Myself, not sure I would do it in fear of ruining a small journal 327 crank.

My thoughts exactly. I have run some engines without the threaded crank and so far have yet to lose my first balancer.

I'm in a bit far now to drill the crank anyway!

go with your first idea of standing it on end on the floor or a block of wood. It's not like your gonna beat it to death.

the -30 outside , and a boiling water for the balancer are great ideas , if your not in a hurry. this is common practice in industry for 'shrinking ' bearings on.

No real hurry, it's something I will likely do one night this week.

They say -26 on Thursday night so that might be a good night to do it!

sounds like a plan, let us know how you make out.  Thank god for cold canadian prairie winters.  Don't leave your beer outside over night - though I'm sure you learned that lesson a long time ago.

Haha, not an issue as the last beer I drank would have been about 1984!

Sure works great for cooling welds though. I hate it in summer when there is no snow or puddles outside!
