The problem
These vehicles can exhibit various defects: - the fourth-gear sprocket on the gearbox main shaft can shift axially, since the circlip may slip out of the groove, - a dog on the fourth-gear sprocket on the layshaft may break off in the event of a violent gear-change. The main shaft including the fourth-gear sprocket and the associated clips and washers must be replaced on all vehicles. The fourth-gear sprocket on the layshaft must also be replaced with a modified, reinforced version.
