All gears are in constant mesh with their counterparts on the layshaft at all times. |
This engine's innovative design incorporates an input shaft flanked by two layshafts, and each layshaft has its own set of final drive gears. |
To be able to undo both the layshaft and mainshaft nuts you must select two gears, normally 1st and 4th gear. |
When the torque exceeds said value the torque limiting clutch 27 of said layshaft slips so that the torque in excess of said value is transmitted by the other layshaft. |
The synchros are there to match the layshaft to the speed of the gear you shift to while in neutral. |
It was decided to achieve the required gear ratio a layshaft would be employed connected to both axles by chains. |
