Thinking about getting this 97

[Grog6]

I was looking at my dirtbike main bearings; rollers pressed into a magnesium case that had too thin of a cross-section, and is broken around the entire bearing cup. Crap. Welding magnesium sux.

Bearings usually stay where they're supposed to. It's when they go bad that they come out. rollers don't, plain bearings stick...
Matt, was it your 2v that lost oil pressure?

Rear wheel bearings are press fit, as are cam bearings in pushrod engines, the control arm bushings, ball joints, numerous transmission bearings etc

Don't forget about the venerable Ford 2.3 press fit cam bearings. I'm sure there are other non pushrod engines with press fit cam bearings.

Hey, only I’m allowed to be pedantic round these parts!

Both my 2V and my 4V did, the used HO pickup tube I had turned out to be bent upward. I glittered the oil but I managed to catch it before it damaged anything beyond the rod bearings. Mains, cam caps, even the rod journals on the crank were unscathed. I caught it before the bearings could spin

The 2V I full on spun them, the crank and rods scored scratched and blued and just trashed. The 4 of the 8 bearings were basically 90° from where they were.
