Install longitudinal member paneling (1) and fix in place.
Rivet longitudinal member panel (1) with Ø 6.5x12.5 rivet (area C).
Clamping range 3.7 mm up to 4.8 mm.
Rivet longitudinal member panel (1) with Ø 6.4x14.0 countersunk-head rivets (area D 1).
Clamping range 2.5 mm.
Rivet longitudinal member panel (1) with Ø 6.4x15.5 countersunk-head rivet (area D₂ ).
Clamping range 3.9 mm up to 4.5 mm.
Longitudinal member paneling (1) (areas E).
Longitudinal member paneling (1) (areas F).
Perform inert gas welding at intervals and allow welding areas to cool down in between. This reduces heat distortion.
Grind inert gas welds down flat.
Solder surfaces on longitudinal member panel (1) with body solder and smooth (areas F).
Alternatively to restorage of the surfaces with body solder it is also possible to use a body basic spatula.
Remove solder residues or grinding dust.
