The drive from the engine / fluid coupling to the driving axle is transmitted by means of two propeller shafts as follows:
First shaft from the fluid coupling to the gearbox
Second shaft from the gearbox to the driving axle
The first shaft incorporates the freewheel mechanism and, on early cars, is fitted with two types of universal joint, the one at the engine end being of the plain bearing type, the other being the needle roller bearing type. On later cars both universal joints are of the needle roller type.
The second shaft has a sliding universal joint at one end and both joints are of the needle roller bearing type.
On early cars the drive from the engine to the radiator fan is via two shafts as follows:
First shaft from the engine to the relay bracket
Second shaft from the relay bracket to the fan
On late cars only one shaft is fitted between the right angle fan drive and the fan.
All shafts between the engine and the fan have a sliding universal joint at one end, the joints being of the needle roller bearing type.
