How much oil will a 1/4 - 5/16 Passage flow under 60psi?
How much oil bleeds out from the bearings in question?
At what pressure can we call it enough to be safe at the bearing?
I can’t see how a radius flow path is bad or non helpful.
The .250-.312 passage will feed a ton more oil than what the bearings require. I fed mine with a number 4 hose, and that’s .250 or so. And that was plenty. Probably could have done it number 3 lines.
