Bevel Wheel (Continued).

The N.S. oil-seal was satisfactory, but the O.S. had been damaged by the bent axle shaft and a large quantity of oil had leaked past in consequence. A slight amount of oil had leaked past the seal on the pinion.

Both axle-shaft drives, Ex.25109, were scored on the outside of the hub, that on the O.S. being very bad. The tubes were also scored in corresponding positions. We consider that the clearance at this point (.006") is definitely too small. Axle tube, GB.2033, was distorted by the smash, also O.S. end plate G.100823.

"Girling" Rear Brakes ex 1.B.IV chassis.

Before dismantling these worked easily, no increase in effort being required for their operation. No undue wear had taken place on the working parts which were free from rust or corrosion.

The Brake Linings, Ferodo B.Z., were in good condition and the Lepex Liners ex B.56.BN.{W.O. Bentley / Mr Barrington} (Mileage 12,900) though grooved, were only slightly worn.

The rear equaliser on the axle tube was in poor condition, though this may be in part due to the accident. The spindle was very loose in the swiveling bracket, which in turn was loose in its thread in the axle-tube bracket. In addition, the ball races of the equaliser levers were indented. These latter were lubricated by some grease used by the manufacturers and packed in when originally fitted. The threaded bearing for the swiveling bracket was lubricated through a bijur valve.

The idler-lever on the axle-tube bracket had been broken by the crash.

Propeller Shaft LOP.GB.702.

The trunnion housings had been distorted by the crash, but all other parts, including the sliding splines, were in good condition and well lubricated.
