It allows eight basic synchronised gear ratios: – four gear ratios: 1st, 2nd, 3rd and 4th; – two range ratios: Hare and Tortoise. Its main characteristic is its assembly of three single cone synchronisers. The main gearbox consists of four synchronised gears. A gear idle-mounted to the output shaft and controlled by a synchroniser allows the four initial gears to be doubled to obtain the eight basic gears. The layshaft and the intermediate shaft are supported by tapered roller bearings. The output shaft is fitted on two tapered roller bearings and one needle roller bearing. The layshaft bearing cups are fitted up against the housing. All gears have helical teeth and are constantly meshed. To ensure optimum gearbox reliability, the bearings are fitted: – with preload for the layshaft, – with clearance for the intermediate shaft. The output shaft may be set either with a slight clearance or a slight preload.
