Diesel engines are famous across a wide variety of industries for being workhorses that can provide tens of thousands of hours of power without a hitch. However, that trademark reliability is predicated on regular inspection and care by knowledgeable and dedicated professionals.

At Worldwide Power Products, repair and maintenance of industrial diesel engines and diesel engine generators is one area of services covered by our expert mechanics and technicians. We’re available anytime, anywhere for everything from routine upkeep to complete overhaul so that your engine is always ready when you need it.


Industrial Diesel Engine Repair & Maintenance

  • Preventive maintenance and repairs performed in our cutting-edge workshop or in the field.

  • All major genset brands covered including Caterpillar, Olympian, HiPower, Cummins, Kohler, and Marelli.

  • Avoid higher costs of repairing equipment after problems arise.

  • Prevent diesel engine damage by overheating with regularly scheduled service and testing.

The two things all our customers have in common when it comes to their diesel equipment are they all want to maximize the ROI and minimize the downtime. And our advice is always the same: don’t skimp on the maintenance. 

Harsh weather, pests, “wet-stacking” (when unburned fuel builds up in a generator due to the unit not reaching its designed operating temperature), or even just inactivity increase the odds of malfunction and shorten the life expectancy of your engine, so you have to be proactive in caring for it. Some of the procedures Worldwide Power Products can undertake include load bank testing (required for all life safety standby generators), oil changes, fuel management, analysis, and filtering, and generating our comprehensive Maintenance Service Report.


Repair Your Industrial Diesel Engine Any Time, Any Place

At the Worldwide Power Products facility in Northwest Houston, we keep Greater Houston’s power needs covered by offering not only sale and rental equipment for commercial, industrial, and municipal operations, but also repair and maintenance for all these applications, as well. At our cutting-edge workshop we conduct rigorous testing, refurbishes, total overhauls, and much more. 

Of course, moving a 1- or 2-ton engine is not always a feasible course of action. That’s why Worldwide Power Products offers on-demand field service at your place of business. Our customers can contact us day or night, 365 days a year for emergency repairs by our certified technicians. If a repair can’t be done in the field and you need a generator ASAP, we can get a rental to you in as little as four hours (subject to availability).


Repairs for Several Industries

When it comes to repair coverage, Worldwide Power Products is universal. No matter what industry your business falls into, if you need power, you can rely on our end-to-end power equipment protection solutions.

Worldwide Power Products customers trust us with their diesel engine repair for a wide variety of industry-specific machinery:

  • Oil and gas: Includes both diesel-powered equipment such as draw-works and mud pumps and “prime movers” that power entire rigs. Worldwide Power Products specializes in delivering generators on short notice to businesses in the petroleum industry that stand up to the high humidity, cold weather, and/or low oxygen of many of these sites.
  • Mining: Shovels, drills, heavy-duty conveyor belts, dump trucks, excavators, shearers, and roof support carriers.
  • Construction: Bulldozers, backhoes, front-end loaders, cranes, graders, and more.
  • Local government: Generators for public hospitals and government buildings, both prime power and emergency backup; school buses, public buses, and municipal vehicles.


Our Inspection & Repair Process

A typical maintenance inspection by our technicians includes a variety of visual checks and minor repairs to keep your unit performing optimally. For example, on a generator inspection, our team will check the air filter for dirt and replace it if necessary; check starting batteries and cables for corrosion and verify electrolyte levels (for open-cell lead-acid batteries); check the levels of oil and coolant and search for any leaks; and check the drive belt for appearance as well as proper tension. 

This is just a small sampling of the many maintenance functions we undertake on a typical service call, but it should illustrate how complex diesel engine repair can be and why you only want to entrust yours to dedicated pros.


Extensive Parts Inventory to Repair Your Engine

Many of our customers prefer to do their own diesel engine repairs in-house, but their local hardware store doesn’t have what they need. We’re proud to partner with hands-on DIYers by stocking those hard-to-find, specialized parts in our huge inventory (and if we don’t have it, we’ll help you find it quickly). These include new, refurbished, and used in good condition engine-related items such as:

  • gears
  • flywheels
  • oil pans
  • camshafts
  • air cleaners
  • cylinder heads
  • turbochargers
  • housings

…and much more! All parts we sell have been rigorously inspected and are ready for immediate install.


Repairs Carried Out by Trained & Certified Technicians

Even the best engine is only as reliable as the people working on it. At Worldwide Power Products, we staff some of the most experienced men and women in the industry who collectively boast thousands of hours of training and real-world work. They’re also folks who create new ways to solve problems, perform their work cleanly and safely, and go above and beyond to please our customers.

Preventive Maintenance – Have Your Generators Inspected Before a Problem Arises

Depending on your needs, you can schedule to have Worldwide Power Products technicians inspect and maintain your diesel generator on a monthly, quarterly, biannual, or annual basis to help you avoid major repairs down the road. In addition to routine checks on components such as the battery, transfer switch, water trap, hoses, drive belt, and crankcase breather, there are two in-depth services we recommend:

  • Load bank testing: Your generator is exercised to maximum capacity in order to verify all components are working and the genset is capable of delivering the required power when needed. This is a more thorough test than a regularly programmed exercise that may run a smaller load, and it should be done at least once per year.
  • Fuel management, analysis, and filtering: As an additional option for protecting the life of your generator, Worldwide Power Products offers diesel fuel polishing that ensures your fuel is being adequately circulated so that sludge and condensation don’t build up and harm the unit.


Vast Array of Replacement & Rental Diesel Engines

If your diesel engine has reached the end of its life or faces an extended repair time, take advantage of Worldwide Power Products’ huge inventory of equipment for sale or rental. For a temporary replacement generator, we rent diesel units in power classes ranging from 20kW all the way up to 1000+kW. We also offer natural gas gensets from all of the top manufacturers, as well as light towers, load banks, and cables.

For new purchases, we sell all types of new and used generators and generator ends; diesel, natural gas, and marine engines; dual-fuel systems; and parts and accessories such as trailers, transfer switches, and radiators.
