• Precision Bore: Features a 90.96mm bore diameter with high-precision machining for optimal piston-to-wall clearance.
• High-Quality Material: Manufactured from high-grade alloy material for excellent strength, anti-deformation properties, and thermal conductivity.
• Advanced Honing: Cylinder walls feature a plateau honing finish to reduce piston ring friction and extend engine life.
• Structural Integrity: Reinforced ribbed design withstands high combustion pressures, ensuring stable engine operation.
• Essential for Rebuilds: Must be replaced during major engine overhauls if the cylinder is scored or worn beyond service limits to maintain compression and sealing.

✅ Fault Indications: Common signs of cylinder bore wear or damage include:
• Blue exhaust smoke (burning oil);
• Low cylinder compression, resulting in power loss;
• Excessive crankcase ventilation blow-by;
• Unusual engine noises (e.g., piston slap);
• Coolant in the oil (if the cylinder is cracked).
If these symptoms occur, inspect the cylinder bore and piston assembly immediately.

✅ Installation Tip: Thoroughly clean all mating surfaces before installing the new cylinder. Always use a new head gasket and tighten cylinder head bolts to the specified torque and sequence in the service manual. When installing pistons, ensure piston ring gaps are staggered. Professional installation by an experienced technician is recommended.
