Melling pump cover bolt torque

Got it fixed, it was the outer gear was binding, uses a red 3m scuffing pad to clean those off enough to clear, plus used a razor blade to clean the high spots off the tips of the inner gear. Benched tested of sorts feed it oil and sound it with a drill and driver, kept feed it oil till the black stuff turned clear, probably the coating breaking in. Now just need to get another 5/8" plug to fully reassemble.
