The 800154602 engine is manufactured to strict OEM standards, ensuring perfect fitment and compatibility with original XCMG grader systems. It is a critical component for maintaining machine productivity and uptime in demanding grading applications.
The 800154602 Engine features a turbocharged, after-cooled design with common rail fuel injection. It produces 200 hp (149 kW) at 2200 rpm, with a peak torque of 820 Nm at 1400 rpm. The engine meets Tier 3 / Stage IIIA emission standards, making it suitable for global markets. The compact inline 6-cylinder layout provides excellent torque rise for heavy blade loads. As a genuine XCMG part, it matches the original mounting points, cooling system, and electronic controls exactly.
Engineered for durability, the 800154602 Engine has a cast iron block and cylinder head, forged steel crankshaft, and replaceable wet cylinder liners. The engine includes a gear-driven coolant pump, full-flow oil filter, and dual fuel filters for extended service intervals. Each engine is dynamometer-tested before shipment to verify power, torque, and emissions. Using OEM engines eliminates the risk of improper calibration or component mismatch, ensuring reliable operation and long service life.

Aftermarket engines often lack proper calibration, leading to poor performance and high fuel consumption. The genuine 800154602 Engine from XCMG is factory-calibrated for GR series graders, ensuring optimal power delivery and fuel efficiency. Independent tests show that OEM engines consume 12% less fuel than generic alternatives while providing 8% more torque rise. This reliability translates to lower operating costs and higher resale value.
Each 800154602 Engine is traceable to its production batch, with full documentation of component origins and assembly results. The engine block is stamped with the XCMG logo and serial number for easy identification. XCMG’s quality system includes 100% dynamometer testing to verify power, torque, and emissions compliance. Only engines that meet all performance targets are shipped.
Installing the 800154602 Engine requires proper lifting equipment and a clean workspace. Use the lifting eyes provided on the cylinder head. Align the engine mounts with the grader frame and install the isolation mounts. Torque the mounting bolts to 180 Nm. Connect all fluid lines, wiring harnesses, and cooling hoses according to the service manual. Fill with 15W-40 engine oil and coolant before starting.
Inspect the 800154602 Engine every 250 hours for oil leaks, belt condition, and coolant level. Change engine oil and filter every 500 hours under normal conditions. Replace fuel filters every 500 hours and air filters as indicated by the restriction gauge. Use genuine XCMG filters and lubricants to maintain warranty coverage. Store spare engines in a dry, covered area with the intake and exhaust ports sealed.
A worn or non-original engine causes poor grade control, slow travel speeds, and high fuel consumption. The genuine 800154602 Engine restores original power and response, allowing the grader to maintain blade speed under heavy loads. Operators report improved grade accuracy and shorter cycle times. The engine’s advanced combustion system also reduces visible smoke and meets strict emission regulations.
In a fleet study of 25 XCMG GR215 graders, machines equipped with genuine 800154602 Engines achieved 15% higher productivity over 5,000 hours compared to those with rebuilt or aftermarket units. The improved reliability reduced unplanned downtime by 70%, saving an average of $8,000 per machine per year in lost revenue. For contractors who depend on their graders, an OEM engine is a smart long-term investment.
XCMG’s engine plant uses automated assembly lines with robotic torque control and real-time data logging. The 800154602 Engine block is cast in-house using high-pressure molding for consistent wall thickness. The crankshaft is forged and induction-hardened for maximum fatigue life. After assembly, each engine undergoes a 2-hour break-in cycle on a dynamometer, followed by a full power curve verification.
All 800154602 Engines are shipped in heavy-duty wooden crates with internal desiccant and humidity indicators. Each crate includes a CD with the service manual and parts catalog. XCMG’s global service network provides technical support and fast parts delivery. For fleet customers, engine exchange programs are available to minimize downtime.
The 800154602 Engine directly replaces original part numbers 800154601 and 800154603. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders manufactured from 2012 onward. This engine is also used in certain XCMG wheel loaders and rollers. For applications requiring lower emissions (Tier 4 Final), use part 800154604. Always verify your grader’s serial number before ordering.
When replacing an engine, also order the installation kit (part 800154605) which includes new mounts, hoses, and wiring adapters. XCMG recommends replacing the radiator and water pump at the same time to ensure cooling system reliability. Keep one spare 800154602 Engine in your warehouse if you operate a large fleet. For emergency rebuilds, short-block assemblies are also available.
For custom configurations (e.g., alternative governor settings or PTO drives), use the buttons above to contact our engine specialists. We can also supply engines with cold-start kits for Arctic operations. Always provide your grader’s serial number when ordering the 800154602 Engine to ensure correct calibration.
