The guide outlines the standard torque ranges for critical joints, with notes on whether a torque sequence or progressive tightening is required. When applying lubricant, use the recommended lubricant type and quantity to avoid excessive film buildup or contamination of the working surfaces. Lubrication points are clearly identified by service marks on both moving and stationary assemblies, and documentation should include the lubrication interval and any environmental considerations that could alter lubricant performance. Always inspect fastener seats and gasket surfaces after tightening to verify seating integrity and to detect any signs of overtightening or thread damage. Proper torque and lubrication practices contribute to consistent performance, reduced vibration, and extended service life of the SABRE 2354HV system.
Adhere to the specified lubrication schedule to minimize wear on bearings, gears, and linkages. When re-lubricating, remove old residue and clean mating surfaces to ensure optimal film formation. The manual notes any lubrication temperature requirements and viscosity recommendations relevant to ambient conditions or operational loads. In high-load or high-temperature environments, re-check torque after a short run-in period to confirm that fasteners maintain proper clamping force. Document all torque values and lubrication points in the service log for traceability and for informing future maintenance cycles.
Measurement and tolerance references
Measurement procedures in this section cover dimensional checks, runout tests, and alignment verification essential for correct assembly and performance. Use calibrated tools and record instrument serial numbers, calibration dates, and tolerance limits to ensure traceable results. Each measurement category includes acceptable tolerance bands, measurement methods, and sampling guidelines to determine if components meet specification or require replacement. When tolerances are outside the specified range, document the deviation, assess potential root causes, and implement corrective actions before continuing with service. Accurate measurements prevent premature wear, misalignment, and compromised safety during operation of the SABRE 2354HV platform.
Special attention is given to critical assemblies where small deviations can produce audible or functional faults. The references cover runout, flatness, and concentricity checks, with step-by-step descriptions to reproduce consistent results. Maintain an evidence trail by attaching measurement sheets to the maintenance record and noting any adjustments made to restore within tolerance. Regular verification of measurement references and calibration tools ensures continued reliability of the equipment and supports long-term performance goals. The appendix emphasizes using manufacturer-approved gauges and following exact measurement sequences to avoid false readings and to support accurate diagnostics during troubleshooting.
