Comprehensive Engine Repair Services

Diagnostics and Troubleshooting

Before any repair work begins, our technicians utilize advanced diagnostic tools to pinpoint the exact issue plaguing your engine. Whether it's a misfiring cylinder, a faulty fuel injector, or a compromised turbocharger, we identify the root cause to ensure precise repairs.

Component-Level Repairs

Not every engine problem requires a complete overhaul. Often, specific components like the water pump, timing belt, or valve lifters might be the culprits. At Northern Hydraulic & Fleet Service, we specialize in component-level repairs, ensuring that only the affected parts are addressed, saving you time and money.

Engine Rebuild and Overhaul Services

Complete Engine Rebuild

An engine rebuild is more than just replacing parts. It involves taking the engine apart, inspecting each component, cleaning, and then replacing or repairing parts as necessary. Our technicians ensure that every part, from the crankshaft to the smallest bearing, meets the highest standards of quality and performance.

Overhaul for Extended Lifespan

Over time, even well-maintained engines can show signs of wear and tear. An engine overhaul involves replacing parts that are worn out but not necessarily broken. This preventive measure can extend the lifespan of your engine, ensuring that your fleet remains operational for longer.

Conversion Services for Enhanced Performance

Fuel Conversion

With the rising costs of fuel and the push for greener alternatives, many fleet owners are considering fuel conversions. We offer services to convert engines to run on alternative fuels like CNG (Compressed Natural Gas) or biodiesel, providing both economic and environmental benefits.

Powertrain Upgrades

For those looking to enhance the performance of their trucks, we offer powertrain upgrades. Whether it's upgrading the transmission for better torque or retrofitting a more efficient exhaust system, our team can provide solutions tailored to your needs.

Maintenance: The Key to Engine Longevity

Regular Oil and Filter Changes

The lifeblood of any engine is its oil. Regular oil and filter changes remove contaminants that can wear down engine components. We use high-quality oils and filters to ensure that your engine remains lubricated and runs smoothly.

Cooling System Maintenance

An overheated engine can lead to catastrophic failures. Our technicians ensure that the cooling system, including the radiator, thermostat, and coolant, is in top shape, preventing overheating and potential engine damage.

Fuel System Cleaning

A clean fuel system ensures optimal combustion and fuel efficiency. We offer fuel system cleaning services that remove deposits and contaminants, ensuring that your engine gets a clean supply of fuel for maximum performance.

Had a good experience here. Had to bring my new Airflo dump body in for some adjustments. They had it in the next day and done in one day. It works great now, the way it should. Good communication too.
