6D34 Main Bearing & Con Rod Bearing ME995175 ME995170 for Mitsubishi Engine Parts

Product Details

Product Overview

This product listing offers a complete set of high-quality main bearings (ME995175) and con rod bearings (ME995170) specifically designed for the Mitsubishi 6D34 diesel engine. These precision-ground bearings are essential components for engine rebuilds and overhauls, ensuring the crankshaft and connecting rods operate with minimal friction and maximum durability.

Manufactured to meet original equipment manufacturer (OEM) specifications, these bearings provide a reliable replacement solution for a wide range of heavy-duty applications. The 6D34 engine is commonly found in various construction machinery, industrial equipment, agricultural tractors, generator sets, marine vessels, and material handling equipment. Please verify your specific engine model and existing part numbers to confirm fitment before purchase.

Key Features & Benefits

• OEM Specification Fit: Manufactured to the exact dimensional tolerances of the original Mitsubishi 6D34 bearings, ensuring a proper and secure fit.
• High Wear Resistance: Constructed from a durable multi-layer material (typically steel-backed with a copper-lead or aluminum alloy lining) designed to withstand high loads and temperatures.
• Complete Set: Includes both main bearings (ME995175) and connecting rod bearings (ME995170) for a comprehensive engine overhaul solution.
• Reliable Performance: Provides excellent oil film retention and heat dissipation, critical for extending engine life and preventing catastrophic failure.
• Easy Identification: Clear part number markings (ME995175 & ME995170) on the bearings or packaging for simple cross-referencing during installation.
• Rigorous Quality Control: Each batch undergoes inspection to ensure dimensional accuracy, surface finish, and material composition meet industry standards.

Technical Specifications

OEM Cross-Reference

FAQ

Q1: How can I be sure these bearings will fit my 6D34 engine?
A: You must verify the part numbers stamped on your old bearings. This set specifically replaces Mitsubishi part numbers ME995175 (main) and ME995170 (con rod). If your engine uses these exact numbers, the fitment is guaranteed. We do not recommend purchasing based on engine model alone, as different engine serial numbers may use different bearing sizes (e.g., STD, 0.25, 0.50 undersize).

Q2: What is the proper installation procedure for these bearings?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the bearing bore and crankshaft journal. 2) Checking the bearing crush height and oil clearance using Plastigage. 3) Applying clean engine oil to the bearing surface before assembly. 4) Torquing the main bearing caps and connecting rod bolts to the manufacturer’s specified torque settings. Improper installation can lead to bearing failure.

Q3: What maintenance is recommended after installing new bearings?
A: After installation, it is critical to prime the oil system before starting the engine to prevent dry start-up. We recommend an initial oil and filter change after the first 50-100 hours of operation to remove any debris from the break-in process. Regularly monitor oil pressure and listen for unusual knocking sounds, which could indicate incorrect clearance or a lubrication issue. Use high-quality diesel engine oil with the correct viscosity (e.g., 15W-40) as specified by the engine manufacturer.
