Todd,
 A high quality (strong) carb cleaner will erode babbit style bearings
left in the solution for a length of time. one the last Mercedes engine
I overhauled, I soaked the piston & connecting rod assemblies. I was in
a hurry and left the old rod bearings in the rods. I intended to replace
them anyway. After 2 hours in my cleaner, at least .004" was eatten off
the babbit. One way to avoid this would be to coat the babbit area with
something that is unaffected by the carb cleaner. Perhaps a heavy
coating of grease would work if the parts were watched carefully and not
left in the cleaner for too long.

PS. When overhauling an engine, why reuse bearings unless they are
totally without wear? That seems like false economy to me.

I was pointing out that Bruce Turentine does not take this precaution in his
video.  I don't understand why bearing replacement is not performed either.
It would seem to be a prudent precaution.  How difficult is it to replace
the Bearings?

Also, their are several different materials that can be used for bering
material.  Perhaps the Mazda bearings are not effected by the cleaner...
