Motors	Walk-by “5 senses” each shift; compare to what’s normal for THIS motor. Never silence a repeating trip without logging the code and calling maintenance. Report new noises, hotter-than-usual endbell, burnt smell, or unusual purge immediately. Keep guards on; keep fins/vents clear; don’t hose TEFC breathers. After sanitation, verify free rotation and no water ingress at junction box.	Noise + heat at endbell? → Bearing check: ultrasound/vibration → lube verification → alignment/belt tension. Trips/overcurrent without noise? → Electrical: phase/voltage balance, loose lugs, insulation IR; check load for jams. Torque ripple on VFD + harmonics? → Power quality/THD; rotor/MCSA for bar faults; add line/reactor or filter. Hot stator, cool bearings? → Cooling blockage, overloading, duty outside spec. High axial vibration? → Misalignment/soft foot; coupling condition; thrust issues (vertical machines).	“Sounds different,” “hotter than usual,” “burnt smell,” “keeps tripping,” “more grease leaking than normal,” “fan not blowing.” Voltage unbalance: >2% (NEMA) → investigate; >3% action. Current unbalance: >10% of avg phase = action. Vibration overall: >25–40% over established baseline (or ISO 10816/20816 zone change). Bearing temp rise: >15 °C above steady baseline or >80–95 °C absolute (per bearing/lube class). Insulation resistance: trending down >50% from baseline, or < recommended per kV/HP and temp-corrected. Grease purge/contamination: visible metal fines, dark burnt grease → inspect immediately. Starts/hour: exceeding design; repeated trips/resets.

V-belt pulleys	If the belt rides high or squeals, check pulley wear & alignment immediately
Torsion spring	If torque feels weak or spring arms look bent, replace before total failure.
Bearings	If you hear a faint hiss or feel heat at the housing, call maintenance before it escalates — early action can save the shaft and housing.	Grinding/hissing, hot to touch, debris visible → Check lubrication & alignment, avoid shock loading.	Monitor vibration levels regularly; sudden spikes may indicate issues. Set temperature thresholds for automated alarms. Use machine learning algorithms to analyze historical data and predict potential failures.	High

Gears	If gear noise changes pitch or gets louder, stop and inspect — changes often mean misalignment or lube failure is starting.	Whine/rumble with gear mesh, hot housing, tooth wear debris → Maintain alignment, gear lube, and load balance.	Monitor gear meshing patterns for irregularities. Analyze vibration spectra for signs of wear or misalignment. Implement thermal imaging to detect abnormal temperature distributions.	High
Pulley				Medium
Sprocket	If it gets noisier or you see dust on the guard, call for lubrication and alignment check now—don’t crank the tensioner; that only hides the problem and speeds up wear.”	Keep it clean, aligned, and oiled—catch chain stretch early, or the sprocket pays the price.	Monitor for changes in chain tension and alignment. Analyze vibration patterns for signs of misalignment or wear. Implement regular inspections for signs of chain wear. Chain elongation ≥ 1.5–2.0% (ANSI duty dependent). UE (ultrasound) +8–12 dB from baseline that doesn’t normalize after relube. Vibration: rising sprocket-mesh frequency sidebands; GMF harmonics trend +25–40%. Temperature screening: sustained abnormal rise vs. baseline/sister asset. Visual: tooth hooking, burrs, flank pitting, red/rusty paste, black tar (burnt oil).	Medium

Motors	Correct grease type/interval/quantity; purge strategy by speed/size; keep seals intact. Laser alignment; check soft foot and base flatness; set belt/coupling tension to spec. Keep fins/covers clean; ensure cooling airflow; verify fan direction. Torque terminal lugs to spec; maintain clean/dry junction boxes; desiccant where needed. Grounding/bonding verified; for VFDs, use shaft grounding ring or insulated bearings as specified. Maintain clean, dry environment; avoid washdown ingress (use TEFC/IP rating appropriate).	Smart relays/VFD analytics: trend current, torque, temp, starts, runtime, imbalance; trip on configurable thresholds. Embedded RTDs/thermistors in windings/bearings; PLC alarming. Wireless sensors: vibration, ultrasound, temperature on endbells and base. Automated lube systems with shot control and cycle counters tied to runtime. Protection schemes: overload (thermal model), phase loss/sequence, ground fault, bearing RTD trips.	Measured alignment & soft-foot correction; precision shims. Lubrication standards (type/interval/quantity) + ultrasound-guided greasing. Clean cooling paths; establish max fin ΔP or visual standard. Electrical connection torque audits; periodic IR scans under load. VFD best practices: proper cable, grounding, dV/dt or sine filter where specified; shaft grounding/insulated bearings. Base rigidity and resonance checks; balance as required. Environmental controls (ingress protection, heaters for condensation).	Bearings (40–60%) – lubrication/contamination/misalignment. Stator insulation/turn-to-turn (20–30%) – thermal/voltage stress, contamination. Electrical supply issues (10–15%) – phase imbalance, voltage distortion, loose terminations. Rotor defects (5–10%) – cracked bars/end rings, casting defects (more with high starts/inertia). Cooling/ventilation (5–10%) – blocked fins/fans, ambient heat → secondary insulation failure. Mechanical fit/coupling (variable) – soft foot, misalignment, resonance.
