To be able to undo both the layshaft and mainshaft nuts you must select two gears, normally 1st and 4th gear. |
|
It was decided to achieve the required gear ratio a layshaft would be employed connected to both axles by chains. |
|
Once the clutch is dis-engaged, the layshaft will just slow down and eventually stop spinning all together. |
|
In this way, the layshaft receives its power directly from the engine whenever the clutch is engaged. |
|
All gears are in constant mesh with their counterparts on the layshaft at all times. |
|
At the other end of the motor another plate was made which had a hole drilled for the layshaft and a clearance hole for the motor shaft. |
|
This engine's innovative design incorporates an input shaft flanked by two layshafts, and each layshaft has its own set of final drive gears. |
|
The synchros are there to match the layshaft to the speed of the gear you shift to while in neutral. |
|
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. |
