118mm Engine Piston 23411-93c10 ME072065 For Mitsubishi 6D16 6D16T Hyundai D6BR Excavator R210-5

Product Details

Product Overview

This high-performance 118mm engine piston is a direct replacement for the Mitsubishi 6D16 and 6D16T diesel engines, as well as the Hyundai D6BR engine platform. Designed for heavy-duty applications, this piston is a critical component for maintaining compression and combustion efficiency in excavators and heavy trucks.

Manufactured under the OEM part numbers 23411-93c10 and ME072065, this piston is specifically engineered for use in Hyundai R210-5, R210LC-7H, and compatible Kato and Kobelco excavator models. The 118mm bore size and Al-fin construction ensure reliable performance in demanding earthmoving and construction environments.

As a B2B-grade replacement part, this piston meets strict dimensional tolerances and material specifications. It is ideal for engine rebuilders, equipment dealers, and fleet maintenance professionals seeking a cost-effective alternative to OEM parts without compromising quality.

Key Features & Benefits

• Precision Engineering: CNC-machined to exact OEM specifications (118mm bore, 116.1mm total height) ensuring perfect fitment and minimal installation adjustments.
• High-Strength Material: Constructed from high-strength aluminum alloy with Al-fin reinforcement for superior thermal conductivity and resistance to thermal cracking under high-load conditions.
• Optimized Combustion Chamber: 62mm combustion chamber diameter designed to match Mitsubishi 6D16/6D16T and Hyundai D6BR fuel injection patterns for efficient fuel burn and reduced emissions.
• Ring Groove Durability: Precision-machined ring grooves (2.8K x 2.5mm x 4.0mm) ensure proper ring seating and oil control, reducing blow-by and extending engine life.
• OEM Cross-Reference Compatibility: Direct replacement for 23411-93c10 and ME072065, eliminating fitment guesswork for Mitsubishi and Hyundai engine rebuilds.
• Cost-Effective Solution: Provides reliable aftermarket performance at a significantly lower price point than genuine OEM pistons, ideal for high-volume fleet maintenance.
• Rigorous Quality Control: Each piston undergoes dimensional inspection and material verification to ensure consistent quality across all production batches.

FAQ

Q1: Will this piston fit my Hyundai R210-5 excavator with a Mitsubishi 6D16 engine?
A: Yes, this piston is specifically designed for the Mitsubishi 6D16 engine used in Hyundai R210-5 excavators. The 118mm bore size and 23411-93c10 OEM number match the original specifications. However, we recommend verifying your engine’s serial number and build date to ensure compatibility with any minor design changes in later production runs.

Q2: What is the correct installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Clean all cylinder bores and piston pin bores thoroughly; 2) Apply assembly lubricant to piston skirts and rings; 3) Use a ring compressor to install the piston assembly into the cylinder; 4) Torque connecting rod bolts to manufacturer specifications (typically 85-95 Nm for 6D16 engines); 5) Check ring end gaps with a feeler gauge (spec: 0.25-0.50mm for compression rings). Always consult the service manual for your specific engine model.

Q3: How often should pistons be replaced during engine overhaul?
A: For heavy-duty excavator applications, pistons should typically be replaced every 8,000-12,000 operating hours or during major engine overhauls. Signs of wear include excessive oil consumption, blow-by (crankcase pressure), reduced power output, and visible scuffing on piston skirts. We recommend always replacing pistons in sets (all 6 cylinders) to ensure balanced compression across the engine.
