The only condition under which there can be two tight spots is when there is insufficient clearance on faces B and C, or, of course, when there are errors of manufacture such as eccentric roller, or imperfect cam tracks. We should be very glad if you would let us have your observations on the above, and, if you agree, let us know your opinion of the cause of the tight spots in the gear you tried while you were up here. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
