XCMG XE225U Cummins B6.7 Long Block Diesel Crate Engine Choate Performance

Stop settling for a standard "rebuild." Choate Performance offers a fully remanufactured Cummins B6.7 Long Block specifically configured for the XCMG XE225U. Designed for high-production environments where downtime is a direct hit to your bottom line, our engines are engineered to be smoother, cooler, and significantly more durable than a factory-fresh crate unit.

The Choate Remanufacturing Process We treat your XCMG’s industrial engine with the same "Stock is Not an Option" philosophy we use for our 1,000+ HP competition builds:

• CNC Blueprint Boring: We don't just hone cylinders; we CNC blueprint the block to ensure perfect geometry and alignment, correcting factory casting shifts.

• Precision Balancing: All rotating assemblies are weight-matched to within 2 grams. This minimizes the internal vibration that leads to premature bearing failure under heavy hydraulic load.

• Torque Plate Honing: We simulate the stress of a torqued cylinder head during the honing process. This ensures a perfect ring seal, preventing the blow-by and oil consumption common in high-hour excavators.

• Upgraded Components: Every engine receives brand-new pistons, lifters, and oil pumps. 

What’s Included:

• Fully Machined Block & Crankshaft (Ground and polished to 0.0005" or less)

• New Upgraded Pistons & Rings (Optimized for Tier 4 Final thermal cycles)

• New Main, Rod, and Cam Bearings

• Remanufactured Cylinder Head (New oversized seats and MLS head gasket)

The Choate Peace-of-Mind Warranty

We don’t just build engines; we stand behind them. Every remanufactured XCMG engine is backed by our industry-leading 2-Year / 2,000-Hour Warranty. This coverage protects your investment against defects in materials and workmanship, ensuring that your machine stays in the dirt and out of the shop. We believe in the quality of our CNC blueprinting and precision assembly—this warranty is our promise of reliability to you and your crew.

Ordering Instructions To ensure 100% compatibility with your XCMG's hydraulic pump and wiring harness, our team will contact you after purchase to verify your Machine Serial Number and 8-digit Cummins ESN. This model is designed for Tier 4 Final machines (look for the Blue DEF Cap). Not sure if this fits? Check out our XCMG Troubleshooting Guide.
