Let's try look at the method of release-lever adjustment when assembling a Borg and Beck clutch.
The release lever must be set by means of the special Borg and Beck according to the diagram below:
Assemble the gauge plate in the flywheel, in the position normally occupied by the driven plate, and mount the cover assembly on the flywheel, tightening the holding screw a turn at a time by diagonal selection and ensuring that the gauge plate is correctly centered with the three machined lugs directly under the release levers. Any position of the gauge-plate lugs will give satisfactory results on the 11-in. models which have four release levers.
After the cover assembly has been fitted to the flywheel, place a short straight-edge across the centre boss and the bearing surface of one release lever, then turn the adjusting nut until the lever is exactly the same height as the gauge-plate boss. Repeat the same process for the other levers.
Flywheel is a rotating mass used to maintain the speed of a machine within certain limits while the machine receives or releases energy at a varying rate.
Clutch is one of the pedals used between engine and gearbox in an automobile to disengage or interrupt power transmission.
Gearbox is part of an automobile's transmission containing the train of gears, and to which the gear lever is connected.
Gear is a configuration of the transmission of an automobile or motor car so as to achieve a particular ratio of engine to axle torque.
