Understanding Your Options
When a part fails on your excavator or loader, you have three primary choices: buy a genuine OEM part, buy a quality aftermarket part, or buy a professionally rebuilt part. Each option has its place, and choosing the right one depends on the component, your warranty situation, and your budget.
OEM (Original Equipment Manufacturer)
OEM parts are manufactured by or to the specifications of the original equipment maker — Caterpillar, Komatsu, Volvo, etc. They are the gold standard for fit, finish, and compatibility, and they are required if your machine is still under manufacturer warranty. The trade-off is price: OEM parts typically cost 40–80% more than equivalent aftermarket or rebuilt options.
Best for: Warranty repairs, safety-critical electronic components (ECUs, sensors), and situations where downtime risk is extremely high.
Quality Aftermarket
High-quality aftermarket parts are manufactured by independent companies to match or exceed OEM specifications. Reputable aftermarket suppliers invest heavily in engineering and quality control, and in many cases their parts outlast the OEM equivalent. The key word is "quality" — there is a large range of quality in the aftermarket, from premium manufacturers to low-grade imports.
Best for: Filters, seals, gaskets, wear parts (teeth, cutting edges), and most mechanical components on out-of-warranty machines.
Professionally Rebuilt (Remanufactured)
Rebuilt components are returned to OEM specifications through complete disassembly, cleaning, inspection, and replacement of all worn or failed components. A professionally rebuilt hydraulic pump, for example, will have new pistons, a new barrel, new bearings, and new seals — and will be tested to verify flow and pressure before shipping.
Best for: Major assemblies — hydraulic pumps and motors, final drives, swing drives, alternators, starters, torque converters, and cylinder heads. Rebuilt parts typically cost 30–60% less than OEM replacements and carry the same 1-year warranty we offer on new parts.
Our Recommendation
For consumables and maintenance items — use quality aftermarket. For major assemblies — use rebuilt. For electronics and warranty repairs — use OEM. Call our team with the part number and we will tell you exactly what we recommend for your specific situation.
