The following operation steps are shown on model 223.1.

The superordinate service document as well as the safety information in the service document must be observed.

The graphics show the vehicle from the mechanic's perspective. At the same time, this perspective also specifies the direction in which the rivets must be placed.

1. Install, fit and fix in place crossmember (2) and support angle (3).
2. Drill rivet holes in crossmember (2) and support angle (3) with ø 6.7 mm (areas A₁ , A₂ ).

   The operation step is shown on the left side of the vehicle and must be performed in the same way on the right side of the vehicle.

3. Countersink rivet holes in crossmember (2) and support angle (3) (areas A₂ ).

   The operation step is shown on the left side of the vehicle and must be performed in the same way on the right side of the vehicle.

4. Remove crossmember (2) and support angle (3).
5. Deburr rivet holes at crossmember (2), support angle (3) and body on both sides.
6. Remove drill chips.

7. Apply 2-component adhesive to body in cross-hatched areas.

   Observe pretreatment of bonding surfaces and manufacturer's specifications for drying and processing time of 2-component adhesive.

8. Install crossmember (2) and fix in place.
9. Rivet crossmember (2) with ø 6.3x16 countersunk-head rivets (area Z₂ ).

   The operation step is shown on the left side of the vehicle and must be performed in the same way on the right side of the vehicle.

10. Rivet crossmember (2) with rivets ø 6.5x14.5 (area Y₃ ).

    The operation step is shown on the left side of the vehicle and must be performed in the same way on the right side of the vehicle.
