| -3- FAULTS REPORTED. Bentley con rods. Bad bedding of bearings in housings of rods. This was a complaint of replacement rods. Joint washers for water pump flange joint in sea-cork. Excessive oil consumption on the Continent. Rear Axle complaints. Knock from Driving dogs. Failure of Driving dogs. Noisy axle. Oil leaks. Bentley Front Axle control brackets. The slot for the ball pin being too large. Brakes Squeaks. ATTENTION GIVEN. RRC. has taken the matter up in production and a promise of better work. It should not be necessary to have to file the bearings to fit the housing. This is being taken up with RRC. This has proved unsatisfactory in service and no further supplies are to be used. Tests carried out showed a satisfactory improvement with the fitting of a heavier pressure scraper ring. The cars also automatically become better with mileage. Present production with improved piston fit and scraper rings are a big improvement, most recent high speed test gave 1300 M.P.G. The driving dogs with increased area in the radius made in S/SCR are now in production and Depots are fitting them for replacements. This also applies to cars with fractured driving dogs. Noisy axles chiefly due to incorrect setting of the pinion, due to faulty fitting of the pinion bearings, has been taken up with the Works. The design of radius, etc. has been altered to facilitate correct fitting of the bearings and to give the necessary nip required. Depots have received concise instructions regarding the set-up of the bearings. The oil leaks from axle tube flange joints is being dealt with by increasing the number of bolts from 12 to 18. This comes on in K.186 series. Faulty machining of the slots was reported to RRC. on new brackets received from the Works. RRC/Cy. has assured us that inspectors will check all stages of machining. The present spring fitted to the damper shoe is too highly rated, and is not of much value. We at Kingsbury are trying out a larger dis. and less rated spring. | ||
