I usually "hammer" them in. But I'd like to make a tool to press them in.
I can't help feeling that sometimes when you hammer them in, it can cause some distortion and high spots on the bearing surface.
Yes was thinking the same, set up a port-to-power with the proper dies and push them in. Then I saw RustyRatRod's cam install video using vaseline, that was the ticket with the mopar tap in cam bearing installer, soft taps.
The lube seems to help them go in straight and square, (especially for a novice) instead of digging into the bearings outter race at the block. Easier to start them in the hole, and double check for oil holes line up, easy to tap back and adjust if not starting to line up right.
