Your generator is an investment - and regular maintenance is one of the most effective ways to protect it. Routine preventative maintenance can help identify developing problems, improve reliability, reduce unexpected breakdowns, and extend the operating life of your generator. UMDR offers both one-time generator maintenance services and scheduled preventative maintenance programs for residential and commercial generators. Scheduled service options include monthly and bi-monthly maintenance agreements. Generator Maintenance May Include: • Oil and filter changes • Fuel filter replacement • Battery inspection • Fluid level inspections • Belt and hose inspections • Leak inspections • Operational testing • Generator diagnostics • Troubleshooting • Maintenance recommendations • Documentation of identified service needs • Emergency response for contracted customers Protect Your Generator Before You Need It A generator should be prepared before an outage occurs - not serviced after it fails. UMDR's preventative maintenance services help ensure your generator remains ready to perform when dependable backup power matters most.

When your generator is not operating properly, accurate diagnostics are the first step. Our technicians evaluate generator systems to identify mechanical and operational problems and recommend the appropriate repair. • Generator troubleshooting • Diesel engine diagnostics • Starting system issues • Fuel system concerns • Cooling system problems • Leak identification • Engine repairs • Engine rebuilds • Preventative maintenance recommendations Our goal is to address the source of the problem - not simply the symptom.

Our technicians flush and descale the cooling system to remove harmful deposits and ensure smooth coolant flow. We inspect all hoses, belts, thermostats, and heat exchangers, identifying wear or corrosion before it becomes a problem. A healthy cooling system prevents engine overheating and prolongs engine life.

We bring our expertise to your vessel, no matter where you are. Whether docked at a marina or anchored offshore, our team is equipped for on-site repairs, diagnostics, and maintenance, reducing downtime and eliminating the need for towing.

Precision engine alignment minimizes vibration and reduces wear on couplings, mounts, and shafts. Using laser alignment tools, we adjust the engine positioning to manufacturer specifications, ensuring smoother operation and extended drivetrain life.

We utilize cutting-edge diagnostic tools to interface with your engine's electronic control unit (ECU), identify error codes, monitor live data, and assess component performance. This service helps catch problems early, saving time and costly repairs.

A full teardown and rebuild of your engine to restore it to OEM standards. We replace worn internal components, clean all parts, reassemble to precise tolerances, and run performance tests. Ideal for engines with significant hours or severe internal wear.

Our repowering service involves removing your outdated or underperforming engine and replacing it with a new, fuel-efficient model. We handle sizing, integration, mounts, controls, and commissioning, improving power, reliability, and fuel economy.

We inspect, clean, and test injectors to ensure correct spray patterns and flow rates. If replacement is required, we install new or refurbished units and program them to match your ECU for optimal engine performance and emissions compliance.

By flushing and descaling your heat exchangers and exhaust manifolds, we remove marine growth, salt deposits, and corrosion. This restores thermal efficiency, improves coolant flow, and reduces the risk of overheating and engine damage.

We disassemble, clean, and recalibrate fuel pumps to factory specifications. Mechanical pumps are adjusted for pressure and timing, while electronic units are tested and reprogrammed to ensure accurate fuel delivery, promoting smooth engine operation and reduced fuel consumption.

We collect oil samples and send them for lab testing to detect the presence of metal particles, soot, coolant, and contaminants. This non-invasive method provides a snapshot of internal engine wear and helps schedule proactive maintenance.

Routine oil and filter changes remove sludge, debris, and contaminants from your engine. We use high-quality lubricants and OEM-grade filters to protect internal components, improve performance, and extend engine service life.

We disassemble, clean, and reassemble plate-type heat exchangers to maintain maximum cooling efficiency. Our installation service includes leak testing, gasket replacement, and alignment to ensure proper function under load.

We offer customizable maintenance schedules that include inspections, lubrication, filter replacements, and diagnostics. This reduces the likelihood of failure, increases reliability, and ensures that your vessel remains operational and compliant.

Using high-frequency sound waves, we remove carbon, varnish, and contaminants from fuel injectors, engine parts, and cooling components. This process reaches microscopic crevices and restores components to near-original performance.

A fiber-optic camera is inserted into cylinders and internal cavities to visually inspect components without disassembly. We detect carbon buildup, scoring, cracks, or oil residue, helping you assess engine health without downtime.

We measure and correct the clearance between valves and rocker arms or cam followers. Proper adjustment ensures complete combustion, maximizes power output, and minimizes engine wear or valve damage.

We disassemble, inspect, and rebuild or replace water pumps, ensuring consistent coolant flow. This prevents hot spots in the engine and protects against overheating, which can lead to major engine failure.
