S0041 Extending a Chassis Beam

Models and Markets

Any Chassis that has been split for transportation purposes.

Information

This procedure should be followed in order to extend a chassis that does not line up correctly i.e. there is an unacceptable gap between the weld faces.

1. Ensure that the correct front half of the chassis is being aligned to the correct rear half (same serial number).
2. Ensure that the overall length is correct to 13600-5+10 mm, Including a weld gap 2 +2-1 mm
3. If possible trim the flanges to meet the above requirement
4. If the weld gap (between the 20 mm flange and the 12 mm flange) is greater than 4mm a 200 mm section will have to be cut away from the rear non-conforming flanges and replaced with a longer section of flange (ST31660) that does meet the above requirements See figure 1
5. The replaced section of flange and the chassis joint needs to be welded in accordance with WP-37727 and WP-25693 see figure 2 and 3.

Continue joining the chassis as per the original procedure.
