Roof Panel SHEET METAL REPAIRS A special feature of the S-Series Cab is the availability of complete body panels for repairing the cab. The types of panels available are shown in Fig. 35. These panels enable a service man to restore a damaged cab to new condition without the usual problems associated with cab rebuilding. Extensive metal refinishing is not required and most restoration welds are in areas of low stress. SHEET METAL TOOLS To perform the necessary cab sheet metal disassembly and rebuild work, the special tools listed here should be on hand. Most of these are common to any cab or body rebuilding shop. 1. Electric or pneumatic drill. 2. Sheet metal drill bits. - 3. Pneumatic chisel (SE-2664 or SE-2129). 4. An assortment of C-clamps. 5. MIG welder (SE-2640). 6. Weld wire Spec. No. E70S-3. PREPARING CAB FOR PANEL REMOVAL Before sheet metal repairs to cab can be started some mechanical work must be performed. This will depend on cab damage and which panel is being replaced. Since the side panel (Fig. 36) or door frame is a commonly replaced panel, let us use the left side panel replacement as an example for what mechanical work is required. The following items must be removed: 1. Left door, seat and interior trim. 2. Dash pad and instrument panel left side mounting. 3. Roof and back panel liners. 4. Left scuff plate and floor mat. 5. Windshield and rear window glass. 6. Junction boxes, relays, dimmer switch, wiring harness and brake piping. 7. Marker light harness and air horn supply line. 8. Fuse block, junction block and starter solenoid. 9. Fuel or air tanks. 10. Cowl top outer panel. CTS-4065 PRINTED IN UNITED STATES OF AMERICA Page 23
