Up to the present mileage, the propellor shaft has been free from periods. No wear or slackness can be felt in the universal joints. The sliding sleeve is on the slack side but has not increased during the mileage. REAR AXLE. LOP GB.519. Axle N° Y 4 BE.56 II x 13 ratio. Axle Tubes GB.2033/4 798 Bevel Pinion. GB.405 Bevel Wheel. R & M 5 MDJT 30 Bearing. At a mileage of 5,000, the axle became noisy. Upon examination at the garage, the long 1/4" bolts holding the two halves of the axle casing were found loose, oil had escaped from the loose centre joint. The effect of this was, the pinion and crown wheel teeth picked up under the load. The oil seal on the O.S. driving shaft perished and was of no further use, consequently, oil was forced down the O.S. axle tube, the quantity being such, that it flooded the brakes. The car had to return to the Works as it was not possible to maintain oil in the axle. This was the 11/43 ratio. The axle was rebuilt with a 10/41 ratio to :- LOP GB.619 N° 56 BN.{W.O.
