As a follow up to this discussion, I have had the set of gears installed in my 32 pierce model 54 that were originally in John Dillman’s car which had the above situation. Phil Bray re-lapped John’s gears and made changes that seem to have solved the problem with noice, etc.
Today I picked up the car from the mechanic and drove it about 25 miles. The car runs at better high speeds with fewer engine RPM’s, and no appreciable noise.
I would like to note that I have 5 sets of Phil Bray’s gears installed in my various old cars, including Cadillacs, Packards, Auburn and now my P-A, and I am happy with all of their performance.
In my opinion, Phil has worked out the issues and gear sets from this point forward should be OK.
I am happy with my purchase.
