Clearance over the rotors - .004" max
Outer rotor to body - .014" max
Tip clearance between rotors - .010" max

These are max numbers for replacement. I would want them to be tighter on anything that matters. You can snug up the clearance over the rotors by facing the body with some fine paper on a smooth, flat surface. .004" is a big gap to be losing oil through.

If the results don't match the theory, change the theory.
