REAR SUSPENSION (Spring Frame Models)

The rear wheel is mounted in a fork that is hinged just behind the gear box. The hinge

has robust plain bearings lubricated from a reservoir of 1½ fluid ounces (42.6 c.c.) of

engine oil which is sufficient to last almost indefinitely. Provision is, however, made for

replenishment should same ever be required. A small screw will be observed in the

right-hand end cap of the hinge bearing, upon removal of this screw, oil can be injected

into the reservoir, the screw orifice operating as a level control.

Showing rear sprung frame and " TELEDRAULIC " legs

The rear wheel fork is suspended on springs located in the two " TELEDRAULIC "

legs joining the rear of the fork to the main frame rear loops, and the spring action is

damped by hydraulic dampers identical in design to those used in the "TELEDRAULIC"

Front Fork Assembly.

The hydraulic fluid used is one of the grades of oil specified in the Lubrication Section

for use in the " TELEDRAULIC " Front Forks.

The recommended quantity for each leg is 85 c.c. or a trifle under 3 fluid ozs. of S.A.E. 20

grade of one of the brands specified. For abnormal loads, the next heavier S.A.E.

grade may be used, but unlike the front fork, recoil damping as well as maximum load

capacity is increased by this alteration of grade alone, and under no circumstances should

the oil content of each leg exceed 90 c.c. or roughly 38 fluid ozs. Unless serious doubt

exists as to the correct functioning of the rear legs, owners are advised to leave well alone.

Should the need arise, however, the oil content of each leg should be separately checked

as follows :
