1. Pre-equip tensioning device.

Insert tensioning plates (01a) into tensioner (01) until they engage. Press pins (arrows) to remove the

clamping plates.

2. Pre-adjust tensioning device to approx. 130 mm (a). This makes it easier to insert the rear spring

Fig. 21: Identifying Tensioning Plates And Pins

3. Clamp tensioning device (01) horizontal in vise.

4. Insert rear spring (73) in the clamping plates (01) so that the end of the winding of the rear spring is

roughly parallel with the upper edge of the clamping plates (arrows).

Insert rear spring from the 5th to the 11th rear spring winding (counted from the side with the larger

winding diameter in the clamping plates (6 to 7 windings must be clamped).
