Question How to install the Pilot Bearing into the fly wheel?

The good news is I am learning a lot from all of you out there. The bad news is I still have a lot to learn.
I have a new light weight fly wheel from AASCO and the new pilot bearing for it. My question is, what is the best way to get the bearing into the fly wheel? Preferably without damaging either.
Is this a hammer it in with a piece of wood scenario? Or find a shop with a press scenario? Of maybe a, put the bearing in the freezer and the fly wheel in the sun situation? (I am in FL so putting in outside is not the same a putting it in the freezer)
I did try to just place it in (knowing it would be that easy) and the size of the hole in the fly wheel is close to the bearing, so I believe I have the bearing.

And while I'm at it, do I us general purpose grease to lube the bearing after installation?

Thanks again to all.
Keith P.

Plastic hammer from the crankshaft side. Just get it started evenly and keep tapping until it's flush. Lube with Optimoly or some sort of long lasting grease, like ignition point lube.

I pop things like that into the freezer for a while before installing.

I don't know about copper anti-seize, but I would think wheel bearing grease would be OK.
When I was talking with a rep at Pelican to go through the list of parts, she said I could use the grease I had already bought for the CV joints.
Heading to the parts store today with the goal of finding something similar to what Ivan or John mentioned. If I can't find that, I will look for some high-temp multi purpose for the bearing and the trans input splines.
The Sachs pressure plate and clutch kit came with a small packet of grease, but I don't there it is enough to do the bearing and the splines.

A press is the "correct" way, from the flywheel side. But freezing the bearing, and/or heating the center of the flywheel helps with expansion/contraction issues if you need to HIT it in. Lube won't help with installing it, but should be used own the transmission shaft and guide tube....

Cheers
