When it comes to a heavy-duty CAT diesel engine overhaul, it’s all about restoring performance, reliability, and longevity from the ground up—and that’s exactly what Fisher Power Supply delivers. A proper CAT engine overhaul starts with complete disassembly down to the bare block, followed by thorough inspection for cracks, wear, and defects. From there, every component is cleaned, machined, and brought back to OEM specifications, with wearable parts replaced using new or remanufactured components. Critical elements like the crankshaft, cylinder head, injectors, and block are either reconditioned or replaced, then carefully reassembled with precision attention to detail. The process finishes with testing and quality checks to ensure the engine performs like new—or better. With everything handled under one roof, including machining, diagnostics, and parts supply, Fisher Power Supply provides a streamlined, high-quality overhaul process built on experience, fast turnaround, and a commitment to “Heavy Duty, Done Right”
