For Mitsubishi 4D34 6D34 Major Overhaul Components Piston Ring Excavator Engine Parts

Specification

Description

This set of components is a complete overhaul solution for 4D34/6D34 excavator engines, including core parts such as piston assemblies, piston rings, piston pins, bearings, thrust plates, and oil seals. Manufactured to OE-level standards, these parts precisely match the original engine’s dimensions and tolerances, enabling direct replacement of worn components. The kit effectively addresses common engine issues like oil consumption, power loss, and abnormal noise, restoring the engine to factory performance.

Advantage

Precise OE Fitment: Strictly follows original equipment specifications with tight tolerance control. No additional machining is required during installation, ensuring perfect compatibility and eliminating secondary failures caused by mismatched parts.
Durable Materials & Craftsmanship: Pistons are cast from high-strength aluminum alloy for excellent high-temperature resistance and deformation resistance. Piston rings feature wear-resistant coatings for superior sealing and extended service life. Bearings are made of high-tin alloy, offering outstanding impact and wear resistance, ideal for harsh construction machinery operating conditions.
Complete All-in-One Kit: Includes all critical wearing parts required for a full engine overhaul, eliminating the need for scattered sourcing. This significantly shortens repair time and reduces procurement costs and communication efforts.
Reliable & Stable Performance: Restores engine compression, reduces oil consumption, improves power output, and lowers fuel consumption and emissions, returning the engine to stable and efficient operation.

Performance

Sealing Performance: Multi-stage piston ring design effectively controls oil consumption, prevents blow-by and oil burning, and improves in-cylinder combustion efficiency.
Wear Resistance: Critical friction components are enhanced with wear-resistant processes, maintaining stable performance under high-load and high-temperature conditions, extending the engine’s overhaul interval.
Perfect Compatibility: Engineered specifically for 4D34/6D34 excavator engines, with 1:1 matching to OE specifications for easy installation and like-new performance post-repair.
Operational Stability: Coordinated operation of all components ensures reliable engine performance under complex working conditions, minimizing downtime risks and improving equipment availability.
