152 — Drive-System Diagnostic Matrix

154 — Over-Tension and Under-Tension Fail Differently

Over-tension shortens bearing life while under-tension causes slip and heat. Exact tension must come from manufacturer/component data.

155 — Alignment Protects More Than the Coupling

Misalignment can influence bearings, seals, vibration, coupling elements and power transmission. Measure and correct the complete geometry.

156 — Motor Condition Is Mechanical and Electrical

Temperature, noise/vibration, bearings, cooling and electrical measurements must be interpreted together with compressor load.

158 — Technical / Drive Verification Gate

Verify exact motor/drive components, tension/alignment source, bearing/fastener/guard condition and loaded behaviour. No generic belt-tension or motor-rewind/repair capability is permitted.

160 — AEO / Engineering FAQ Layer
