Document the configuration of hoses and electrical connectors with photos or annotated notes to facilitate accurate reconnection later. Throughout disassembly, handle components gently to avoid bending shifting parts, and store pieces in sequence to replicate the original layout during reassembly. Adhere to torque specifications during fastener removal to prevent thread damage, and inspect gaskets and seals for signs of degradation that would require replacement rather than reuse. Inspection criteria and wear limits demand a methodical evaluation of all removable parts for operational integrity. Inspect bearings for smooth rotation, any roughness, or notable play, and measure clearances where applicable with calibrated gauges to ensure they remain within the manufacturer's service limits. Check gears and splines for pitting, cracks, or abnormal wear patterns; replace any components that show signs of fatigue or deformation. Assess seals and O-rings for brittleness, cracks, or swelling, and replace them if they fail a leak or compatibility test. Examine shafts for straightness and surface wear, and consider micrometer readings for critical diameters to determine whether re-machining is required. Look for corrosion or material loss on housings and covers, noting any hotspots that may indicate overheating or contamination. Verify electrical connections for insulation integrity and continuity, ensuring that wiring harnesses and connectors exhibit secure mating surfaces with no exposed conductors. Finally, confirm that all protective guards, shields, and fastener hardware are in good condition and reinstalled to maintain safety compliance. Reassembly sequencing and torque values must follow a logical, manufacturer-approved order to ensure proper seating and alignment of all components. Begin with the base or foundational assemblies, then reinstall subassemblies in the reverse order of disassembly, confirming alignment marks and fitment at each step. Use new gaskets, seals, and lubricants where specified, and apply a light film of the recommended lubricant to moving interfaces prior to final assembly. Tighten fasteners in a progressive, cross-pattern sequence to achieve uniform clamping force, and verify that torque values are within the specified range using a calibrated torque wrench. After initial assembly, rotate moving parts by hand to confirm smooth operation before applying power, and perform a functional check to verify that controls, safety interlocks, and sensors respond correctly. Document the final torque readings and any deviations from standard values, including notes on components replaced or adjusted, to support future maintenance intervals and troubleshooting.
