What we service
Helical, bevel, worm, planetary, and parallel-shaft reducers; cooling-tower gear drives; mixer/agitation gearboxes; conveyor drives; blower and pump gear units from leading OEMs.
Core maintenance & repair services
-
Condition assessment – visual inspection, endplay/backlash checks, bore and shaft measurement, seal integrity.
-
Lubrication management – oil selection for load/temperature, changeouts, breathers, desiccant filters, sight-glass upgrades.
-
Oil analysis (tribology) – viscosity, TAN/TBN, water, particle counts, wear metals trendline with action limits.
-
Vibration & acoustic monitoring – envelope and FFT analysis to detect bearing defects, gear mesh, looseness, misalignment.
-
Thermal imaging – hot-spot detection for overload, lube starvation, or cooling issues.
-
Alignment & soft-foot correction – laser shaft alignment, baseplate shimming, grout and foundation remediation.
-
Rebuilds & overhauls – bearing and seal replacement, gear inspection/repair, housing machining, run-in testing.
-
Upgrades – breathers, filtration, clear-view level gauges, magnetic drain plugs, condition sensors for predictive programs.

Our proven process
-
Baseline – collect OEM data and operating conditions; sample oil and record vibration/temperature.
-
Plan – risk-rank units, select tasks (clean, align, change oil, rebuild), and schedule around production.
-
Execute – lockout/tagout, contamination control, precision assembly, torque verification.
-
Verify – post-work vibration and thermography, no-load/load run checks, leak inspection.
-
Document – findings, photos, trending plots, and next-interval recommendations.
Signs your gearbox needs attention
-
Rising vibration at gear-mesh or bearing frequencies
-
Oil darkening, foaming, or metallic sheen; frequent top-offs
-
Hot casing or new hotspots in thermal scans
-
Leaks at input/output seals or breather contamination
-
Audible whine, clatter on load changes, or increased backlash
Built for Arizona conditions
-
High ambient heat: viscosity selection, oxidation-resistant oils, and cooling improvements.
-
Dust & fine particulates: upgraded breathers, better seals, contamination control during service.
-
Monsoon moisture: water-ingress prevention, frequent oil sampling during season, desiccant management.
Sample service intervals (guidance)
-
Walk-through inspection: monthly
-
Vibration & temperature route: quarterly (critical assets monthly)
-
Oil sampling: quarterly (critical) / semi-annual (standard)
-
Oil change: per analysis or 12–24 months based on duty and heat
-
Comprehensive inspection/rebuild review: every 3–5 years or by trend
We’ll tailor intervals to your runtime, load profile, and criticality.
Industries we support
Power generation (including cooling tower gear drives), mining & aggregates, manufacturing, water/wastewater, food & beverage, logistics, and municipal facilities across Arizona.
FAQs
Do you service gearboxes from multiple OEMs?
Yes. We work across major brands and can reverse-engineer legacy units when OEM data is limited.
Can you work around production?
We stage work during changeovers or nights/weekends and set up temporary guarding to keep adjacent lines operating safely.
Is oil analysis really necessary?
Oil is your earliest warning system—analysis often catches wear and contamination months before a failure.
Repair or replace?
If gears are sound and housing is in spec, rebuilds are typically faster and more cost-effective. We’ll present both options with lifecycle cost.
