Frequently Asked Questions (FAQ)

Q1: Is this a new engine or a remanufactured one?
A: We supply both new OEM-quality assemblies and certified remanufactured engines. Remanufactured units are completely rebuilt to original specifications with new bearings, seals, gaskets, and re-machined components, offering like-new reliability at a reduced cost.

Q2: What is included in the “engine assembly”?
A: A standard long block assembly includes the core engine (block, crankshaft, pistons, connecting rods, cylinder head) and core-mounted parts like the gear case and water pump. It typically does NOT include application-specific parts like the starter, alternator, flywheel, manifolds, or engine mounts, which are transferred from your old engine.

Q3: Will this engine fit my Kobelco SK75-8 excavator?
A: Yes, the 4LE2 is the direct OEM engine for the SK75-8. However, you must confirm the exact sub-model and configuration (e.g., 4LE2T, turbocharged vs. naturally aspirated) matches your machine’s original specifications to ensure compatibility with all sensors, wiring, and mounting points.

Q4: What warranty is provided?
A: We offer a strong warranty on our engine assemblies (e.g., 12 months or 1,500-2,000 operating hours). Specific warranty terms will be detailed with your purchase.

Q5: Do I need special tools or skills to install this engine?
A: Engine replacement is a major mechanical project. It requires proper lifting equipment, tools, and knowledge to handle alignment, wiring, and fluid connections. For equipment like an excavator, we highly recommend installation by a qualified technician familiar with the machine.
