On the ground floor there was a hurst frame supporting two pairs of stones which were driven by a layshaft from a steam engine and later a mobile oil engine.

Nevertheless, approximate rev . matching " with clutching " can decrease the difference in rotational speed between the layshaft and transmission gear shaft, therefore decreasing synchro wear.

Most of the Canadian buses had the optional Allison Transmission torque converter transmission, but the sole survivor now has a Detroit Diesel 6V-71 engine and a Fuller layshaft gearbox.

For gearboxes in general, gear clusters mounted on a layshaft may either turn freely on a fixed shaft, or may be part of a shaft that then rotates in bearings.

Getrag provided a six-speed manual transmission shared with the Mini Cooper S . This transmission was a twin layshaft design and included a dual mass flywheel to eliminate vibration and transmission noise.

Photographs of the mill during demolition reveal the cast iron low breast shot waterwheel drove three pairs of millstones via a cast iron layshaft . The original wooden upright shaft and crown wheel were retained.
17.
Cone-head lathes usually had a countershaft ( layshaft ) on the back side of the cone which could be engaged to provide a lower set of speeds than was obtainable by direct belt drive.
18.
Where a power take-off is required, usually for industrial vehicles to drive winches, hydraulic pumps etc ., this is often driven from one end of the layshaft, as this is more accessible shaft than the main shafts, already in use by the drivetrain.
19.
The first gear ratio was raised and needle roller bearings were used in place of the bronze bushings on the layshaft . Early 4-speed manual transmission models could be ordered with an A-type Laycock overdrive unit and later ones frequently came with a J-type Laycock unit.

The car that resulted was the TRF414X ( built in very small numbers ), which evolved into the TRF414M, and then to the more popular TRF414M2 ( and the budget-oriented TA04 series ), all employing the then-novel twin-belt drivetrain layout, with the center layshaft mounted above the motor.
