23411-93400 Engine Piston For Hyundai D6br Mitsubishi 6d16 Excavator R210-5 Diesel Engine Spare

Product Details

Product Overview

This high-performance diesel engine piston, identified by OEM number 23411-93400, is a direct replacement component designed for Hyundai D6BR and Mitsubishi 6D16 series diesel engines. Commonly used in heavy-duty applications such as the Hyundai R210-5 excavator, R210LC-3H excavator, and various heavy trucks and generator sets, this piston ensures reliable power output and engine longevity.

Manufactured from high-performance aluminum alloy, the piston features precision machining to meet or exceed original equipment specifications. With a bore diameter of 118.0 mm, it provides the exact fit required for these engine platforms. This component is suitable for both naturally aspirated and turbocharged versions of the 6D16 engine (6D16-T).

As a critical moving part within the combustion chamber, this piston is engineered to withstand extreme temperatures and pressures while maintaining dimensional stability. It is an ideal choice for workshop rebuilds, fleet maintenance, and aftermarket replacement needs.

Key Features & Benefits

FAQ

Q1: How do I confirm this piston fits my Hyundai R210-5 excavator engine?
A: First, check your existing piston for the OEM part number. This piston matches Hyundai/Mitsubishi numbers 23411-93400, 23411-93000, and 23411-93410. Also measure the piston diameter; it should be 118.0 mm. If your engine is a D6BR or 6D16 series (including 6D16-T), this piston is the correct replacement. We recommend comparing the ring groove positions and pin bore diameter with your old piston before installation if possible.

Q2: What surface treatment should I choose for my application?
A: Tin plating is the standard option and provides excellent anti-scuffing properties during initial break-in, suitable for most rebuilds. MoS2 (molybdenum disulfide) coating offers lower friction and is ideal for high-load or turbocharged engines like the 6D16-T. Phosphating provides good corrosion resistance and oil retention. For general excavator applications, tin plating or MoS2 coating are recommended. Consult your engine builder for specific preferences.

Q3: Do I need to replace piston rings and pins at the same time?
A: Yes, it is strongly recommended to install new piston rings and piston pins when replacing the piston. Used rings may not seat properly against the new cylinder wall surface, and worn pins can cause premature wear. For best results, use a matched set of piston, rings, and pin from the same manufacturer to ensure correct clearances and long service life.
