REAR SUSPENSION
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
heavy gear oil which is sufficient to last almost indefinitely. Provision is, however, made
for replenishment should same 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, or sustained high speed,
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 :
