t  If one of the propshaft tubes is damaged, the entire propshaft need not be renewed. The respective propshaft tube can be renewed separately. t  Removing, installing or renewing parts of the propshaft can lead to imbalances which have a negative effect on smooth running. t  Keep propshaft straight; store and transport fully extended only. Do not clamp in vice. t  Before dismantling, mark positions of all parts in relation to each other. Assemble in same position; otherwise an imbalance may be created which causes damage to bearing and rumbling noises. t  Individual propshaft tubes are balanced. To keep imbalance of the entire propshaft as small as possible, observe markings during installation → Chapter.

Markings of propshaft tubes Propshaft tubes are marked with a spot of white paint in the flanges -arrows-. –  If individual parts of propshaft tubes are to be removed, first transfer spot of paint to tube. –  When bolting propshaft tubes together, line up spots of white paint, dot to dot. This will ensure that imbalance present will be kept to a minimum in the entire propshaft.

Pressing off constant velocity joint

Pressing on constant velocity joint –  Press on carefully. –  Tighten tensioner -40 - 204 A- securely. Propshaft must not be pushed down within tensioner, or paintwork will be damaged. –  Repair paint damage: remove residual grease or oil with nitro thinner -L 001 600-. Apply 2 component acrylic paint -ALN 769 041- with hardener -ALZ 009 001-.

Tightening clamp In case of repair, allocate clamp according to → Electronic parts catalogue “ETKA”.
