Put the spring assembly on the brake drums.

Turn the spring assembly of a trapezoidal

leaf spring assembly right side up again, so

head is located in the recess of the bearing

support and that the alignment plates fit onto

the cams of the bearing support.

5.

Tighten the tie rods (4) to the specified

torque. See "Technical data".

Make sure that the attachment nuts fully

engage the tie rod.

rods sticking out above the attachment nuts.
