Question 5

How long does a remanufactured Caterpillar 3126 engine last?

Accepted Answer

A remanufactured Caterpillar 3126 engine typically lasts 200,000 to 500,000+ miles with proper maintenance — comparable to a brand new engine. The longevity of your remanufactured Caterpillar 3126 7.2L depends on regular oil changes, proper cooling system maintenance, using the correct fuel and fluids, and following the manufacturer's recommended service intervals. Our remanufactured long blocks are built to OEM specifications using all-new internal components, which is why they deliver the same service life as a factory-new engine.

Question 6

Is a remanufactured Caterpillar 3126 better than a used or rebuilt engine?

Accepted Answer

Yes, a remanufactured Caterpillar 3126 is significantly better than a used or rebuilt engine because every component is replaced or restored to OEM specifications. A used engine has unknown history and remaining life. A rebuilt engine only replaces worn-out parts. Our remanufactured Caterpillar 3126 7.2L engines are completely disassembled down to the bare block, every component is cleaned and inspected, and all wear items are replaced with new parts — including pistons, bearings, gaskets, seals, timing components, and the oil pump. The engine block and crankshaft are precision machined to factory tolerances, delivering better reliability, longer life, and a stronger warranty than used or rebuilt alternatives.
