We have sent into the Lab. a sample of oil and sludge removed from 32-EX gearbox after a 15,000 miles' test in France. We should like to know of what the sludge is composed, particularly as to whether it contains any copper sulphide or copper chloride. We should also like to know whether the oil has suffered an unusual amount of oxidisation. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
