All components and parts must be carefully checked to determine if they are serviceable for use, can be repaired or must
Inspect drilled and tapped (threaded) holes for the following:
Wear, distortion, cracks, and any other damage in or around holes.
Threaded areas for wear distortion (stretching) and evidence of cross-threading.
Inspect metal lines, flexible lines or hoses, and metal fittings and connectors for the following:
Metal lines for sharp kinks, cracks, bad bends, and dents.
Flexible lines or hoses for fraying, evidence of leakage, and loose metal fittings or connectors.
Metal fittings and connectors for thread damage and worn or rounded hex heads.
Inspect castings, forgings, and machined metal parts for the following:
Machined surfaces for nicks, burrs, raised metal wear, and other damage.

Inspect bearings in accordance with TM 9-214.
DISASSEMBLY AND ASSEMBLY INSTRUCTIONS
Keep major components together whenever possible and practical.
Tag hoses, electrical wires, cables, and harnesses to identify them and aid during installation.
Keep related parts together for identification purposes.
Temporarily install attaching hardware such as screws, bolts, washers, and nuts to prevent loss.
Only disassemble to the point of the problem.
Ensure that parts are clean and lubricated before assembly.
Before welding, the following components must be disconnected to avoid damage to electronic components:
Hydraulic servo system ECU - computer no. 790 (WP 0079 00)
Tophandler ECU - computer no. 791 (WP 0076 00)
Steering system ECU - computer no. 792 (WP 0079 00)
Transmission ECU - computer no. 793 (WP 0079 00)
Engine ECU - computer no. 794 (WP 0079 00)
Electronic Control System (ECS) display screen - computer no. 795 (WP 0080 00)
Repair castings, forgings, and machined parts using the following instructions:
Repair minor cracked castings or forgings in accordance with TM 9-237.
Repair minor damage to machined surfaces with an abrasive cloth dipped in detergent (Item 11, WP 0203 00).
Replace any deeply nicked machined surface that could affect the assembly operation.
Repair minor damage to threaded capscrew holes with thread tap of same size to prevent cutting oversize.
After repair, thoroughly clean all parts to prevent dirt, metal chips or other foreign material from entering any working
