babbit tolerance? .000?

[Jim Brierley]

Railcarmover, I'm not sure the rear bearing would run dry, just don't want to chance it. On my insert engine I run a 1-piece Burtz seal, and it stays dry. I also run a babbitted mains engine on the salt using a rope seal, and it drips a little but not much. Ran 167 mph on babbitt in 2013, no problems with the engine, just turbo failure, so no record.
