Engine Repair: Reviving Your Diesel Power

Why Engine Repair Matters

Diesel engines are known for their durability and efficiency. However, like all machinery, they require regular maintenance and occasional repairs. Common issues like fuel system problems, worn-out cylinders, or damaged pistons can significantly impact your engine's performance. Timely repair is crucial to prevent minor issues from escalating into major complications.

Our Approach

At Harmon Truck Service, we use advanced diagnostic tools to pinpoint issues accurately. Whether it's a simple fix or a complex problem, our team ensures every repair is done right, extending the life of your engine and maintaining its efficiency.

Engine Rebuild: Restoring Your Engine’s Peak Performance

Understanding Engine Rebuild

An engine rebuild involves disassembling the engine, inspecting all components, and replacing worn or damaged parts. It's a cost-effective alternative to buying a new engine, especially for high-value diesel trucks.

Our Expertise

During a rebuild, we meticulously inspect each component. Every part is scrutinized, from the crankshaft, which converts linear piston motion into rotation, to the camshaft, which controls the opening and closing of valves. We replace components like bearings, gaskets, and seals, ensuring your engine runs like new.

Engine Overhaul: Comprehensive Revitalization

When Overhaul is Needed

An engine overhaul is more extensive than a rebuild. It's recommended when your engine has significant wear or damage, affecting its performance and reliability.

Our Detailed Process

We strip the engine down to its core and rebuild it, often replacing major components like the engine block, heads, and pistons. This process restores engine performance and extends its lifespan, offering a cost-effective solution compared to engine replacement.
