RING INK COUPLING LOP.G.80251. E.X.3236.

The fabric coupling shows no signs of deterioration at this mileage.

UNIVERSAL JOINT & PROPELLER SHAFT LOP.G.80001. GL. {G. Linnett} 70B. R.R.SCH.473.
Incorporating Needle Bearings in Mechanics Joints.

The propeller shaft mechanics joints have been a source of trouble in not retaining the grease. The cause of the leak was found to be due to the straining of the joints. This was caused by the rocking over of the axle when the brakes were applied with the hydraulic damper loads at minimum. There is not sufficient control of the axle with the minimum loads of the dampers and the propeller joints are not made to operate at these extreme angles. It would appear that with the adoption of the control to the dampers using light loads, a form of radius rod should be fitted to the axle.

HYDRAULIC DAMPERS AUTOMATICALLY CONTROLLED.

Rear LOP.F.85732. SCH.411 - 469.
Front LOP.85733. SCH.411 - 469.
Strengthened main cylinders with smaller feet and increased dia. bolts.

The loads of the dampers have answered to the control unit and no trouble has been experienced with the control. The weakness of the control pipe lines is the elbows screwed into the dampers. These work loose and cause loss of oil. These could be dispensed with by making the elbow union in one piece with the valve chamber. The riding of the car can be made fairly comfortable by the manipulations of the control for low and medium speeds. At high speeds the car is controllable with maximum loads to the dampers, but we do not consider the riding in the rear seats is good, there is too much pitching. As stated when using the soft riding position there is not sufficient control of the rear axle to prevent it winding round when the brakes are applied.

STEERING COLUMN & BOX. E.X.3768/S. 3768. LSC.5054.
Incorporating friction in the column F.8554X.

There has been a constant knocking in the steering column coming from the friction device housing. The steering tube in the column with this scheme is not supported centrally and the knock is caused by the tube hitting the sides of the column. The friction makes the steering heavy and has not prevented the oscillation of the steering wheel which at times has kicked back at a high velocity.
