8 Speed Synchromesh Shuttle Gearbox

Drive through the 1st, 2nd, 3rd and 4th ratio free-running gears takes place when the selected gear is engaged with the mainshaft by a sliding coupler. The coupler located between the pairs of gears forms part of the synchromesh engagement mechanism. Ball and roller bearings are used to support the main and layshaft.

Gearbox Driveline
The order of drive through the gearbox, with the gears selected is as follows:
From the input shaft through the forward or reverse gear set to the layshaft.
From the layshaft to the selected free-running gear on the mainshaft.
From the free-running gear to the coupler.
From the coupler to the mainshaft via the coupler hub which is splined to the mainshaft.
From the mainshaft to the tractors final drive arrangements via the epicyclic gear reduction unit in LOW range drive or directly in HIGH range.

Synchromesh mechanism
The synchromesh mechanism synchronises (equalizes) the speed of the selected free-running gear with the appropriate driven shaft before drive engagement. This is of great benefit to the drive by preventing potential gear damage and allowing fast, easy gear changes to be made on the move without the need to stop the tractor.
Engaging gear with the tractor stationary is also easier.
