4. Install 3W6474 Step Assembly (10) to the platform using the following procedure: * Use 8 mm (.31") fillet welds in locations (A) and (B).* Use 3 mm (.12") bevel groove weld in location (C).* Use flare bevel groove weld in location (D) and grind flush.* Use 5 mm (.20") fillet weld in location (E) all around.5. Install 3W9005 Step Assembly (11) in a similar manner.6. Weld 3W2713 Gussets (12) to step assemblies (10) and (11) using the dimension shown. Use 3 mm (.12") welds in locations (F) and (G). Weld on both sides.7. Install 5G9901 Step (13) to step assembly (10) by welding from location (A) to location (C). Use 3 mm (.12") fillet welds 25 mm (1") long, with a 75 mm (3") space between welds.8. Install 5G9902 Step (14) in a similar manner.9. Install 3W6478 Plates (15).

10. Install 3W6473 Plates (16) to the radiator guard using the dimensions shown. Use 5 mm (.20") fillet welds all around.11. Tack weld brackets (1) in place using the dimensions shown.12. Remove items (2), (3), (4), (5), (6), (7), (8) and (9).13. Weld brackets (1) in place using: * 6 mm (.24") flare-bevel groove welds in locations (H) (both sides).* 10 mm (.40") flare-bevel groove welds in locations (I) (both sides).* 10 mm (.40") fillet welds in locations (J) (both sides).* 8 mm (.31") fillet welds in locations (K) (both sides).14. Reinstall items (2), (3), (4), (5), (6), (7), (8) and (9).15. Install 3W6358 Tube (17) using the dimension shown with: * 8 mm (.31") fillet welds in locations (L) (both sides).* 6 mm (.24") flare-bevel groove welds in locations (M) (both sides).16. Center 8C3788 Film (18) in available space.
