| ( 6 ) 14) REAR AXLE PERFECT OIL SEAL LEATHERS TO OVERCOME LEAKAGE OF OIL THROUGH THE HUB ON TO THE BRAKE SHOES. No oil has leaked down the Axle tubes. 15) MORE FRICTION ON THE SWINGING ARM TO IMPROVE BRAKE THUMPS. We have not found the increased friction beneficial in preventing front brake thumps. We have found that the friction load remained more consistent. 16) SMITH'S JACKALL JACKS. The front Jacks have not been on the Car since the last report. The new Jacks have been repeatedly used, and no fault has been found in the operation or unreliability. 17) IMPROVED FRONTAL APPEARANCE WITH CENTRALISED WING AND RADIATOR MOUNTING. The Radiator and wing rode very steady during 75% of the mileage. The latter part, they were not so steady owing to the front supporting cross member, having cracked and become loose in the frame. This member has to carry the front of the Engine as well as the Radiator and wings. 18) EXHAUST SYSTEM. The exhaust system as fitted failed, and a standard front box and intermediate pipe were fitted. This has given no trouble. The plain corrugated steel washers for the manifold joint are very good. There has been no sign of any exhaust blows and the manifold has been dismantled several times without any detramental effect to the washers. 19) SMALLER RADIATOR MATRIX. The small type Radiator Matrix has been effecient. No water has been lost since the fitting of the baffle in the filler tube. Tests taken with bonnet louvers covered up, did not affect the water temperature. The Matrix has shown no weakness. | ||
