The driving shafts of the rear wheels are secured by swing axles at the side of the gear box by means of 2 large clips. After many years of service, surcharge or after revision of the gear box, these clips may get damaged or even break. The swing axle cannot be clamped properly into the satellite wheel, which can lead to damage of the swing axle locking. This can lead to a loose swing axle, damaged pinion and damage to the gear box without possible repair. The clips are available each in a good quality from stock.
