PARTICULARITIES
The gears grid is similar to that of the gearboxes previously mounted on the DACIA
SupeRNova vehicles, the only difference being the reverse driving, which is located on the right
side and backwards.
The synchronizers are BORG – WARNER type.
The synchronizing hub – sliding collar, and the synchronizing hub – shaft assemblies are com-
posed of matching parts .
The synchronizing hubs are freely mounted on the secondary shaft and are maintained axially
through safety devices of the ring type.
The cylindrical moment of the differential is not adjustable.
The differential assembly is supported on the gearbox crankcases by means of the bearings.
The primary and secondary shafts support at the clutch side is done by means of roll – bear-
ings, which get into direct contact with the shaft (the bearings do not have inner ring, its purpose
being taken over by the shafts).
The reverse driving pinion is delivered mounted on the shaft.
