Industrial Generator Services
And when it fails, it’s too late to find out the alignment was off, the grout had cracked, or the bearings were screaming for replacement.
At Tillson Industrial, we specialize in the mechanical side of industrial generator systems—making sure they’re ready to run when everything else goes dark.
What We Do
We provide mechanical generator services for diesel- and gas-driven systems used in standby and prime power applications.
We don’t touch breakers, switchgear, or electronics—and we don’t pretend to. Our expertise is in the rotating assemblies, mounting frames, and drivetrain alignments that keep your generator physically sound.
We handle:
- Mechanical disassembly and rebuild of generator frames and rotors
- Engine-to-generator shaft alignment
- Bearing and seal replacement
- Soft foot correction and vibration mitigation
- Base and skid anchoring, leveling, and epoxy grouting
- Pad-mounted and skid-mounted generator support
What we don’t do:
- Electrical diagnostics or testing
- Rewinding or stator repair
- Breaker, ATS, or control panel work
We partner with your generator techs—not replace them. We focus purely on the mechanical performance and reliability of your genset.
Why It Matters
Most generators sit idle for 90% of the year—quietly waiting for their moment. But idle doesn’t mean maintenance-free. Over time, vibration, misalignment, and base degradation take their toll.
The most common mechanical issues we see:
- Misaligned engine-to-generator shafts
- Bearing wear due to soft foot or base flex
- Grout cracking, anchor looseness, or pedestal settling
- Noise, vibration, and seal leakage under load
- Shaft runout and DBSE deviation from OEM targets
These problems don’t show up on a breaker test—but they’ll stop your generator cold when the power drops.
Our job is to make sure your mechanical systems don’t fail when they matter most.
How We Get It Done
1. Inspection & Scope Review
We begin with a full mechanical assessment: frame condition, shaft alignment, bearing wear, pedestal health, grout condition, and fastener torque. We document runout, DBSE, and soft foot measurements to create a clear mechanical baseline.
2. Mechanical Disassembly
Our crews remove guards, couplings, and flexible joints. We’ll disassemble bearing housings, pull shafts, and open up the generator frame to access all critical rotating components.
3. Component Repair & Replacement
We repair worn bores, correct damaged bolt holes, and replace seals, sleeves, and bearings. If base damage is detected, we prep for epoxy regrouting or leveling. Any misalignment or mechanical deformation is corrected with the right tools—not guesswork.
4. Reassembly & Alignment
Once rebuilt, we reinstall the generator onto its pad or skid, shim to level, and anchor per spec. We use laser tools to align the engine-to-generator shaft to within API 686 tolerances or OEM recommendations. Final DBSE is verified.
5. Final Verification & Support
We torque all hardware, confirm free rotation, and support your electrical contractor during load test or commissioning—staying on-site if needed until mechanical systems are cleared for long-term service.
Where We Work
We service generator systems across the U.S. in high-stakes, mission-critical environments.
Common locations include:
- Refineries and petrochemical plants
- Data centers and emergency power facilities
- Hospitals, campuses, and municipal utility systems
- Water treatment plants and lift stations
- Marine terminals, docks, and power yards
- Remote field installations and off-grid applications
Whether it’s pad-mounted or skid-mounted, indoor or rooftop, base-loaded or backup—we make sure your generator system is mechanically flawless.
The Bottom Line
Your generator only has one job. It needs to start. When it doesn’t, every minute of downtime costs more than the fix ever would have. Tillson Industrial ensures the mechanical side of your power system is rock solid—aligned, anchored, and built to endure.
We don’t guess. We don’t “get it close.” We get it right. Or we don’t leave.
