6D24 Connecting Rod Bearing ME994419 STD Size for Mitsubishi Engine Parts

Product Details

Product Overview

This is a premium-quality STD (Standard Size) Connecting Rod Bearing, specifically designed for the Mitsubishi 6D24 diesel engine. Identified by the OEM part number ME994419, this component is a critical wear item that ensures the smooth and reliable operation of the engine’s rotating assembly.

Manufactured to match OEM specifications, this connecting rod bearing is suitable for a wide range of heavy-duty applications, including construction machinery, industrial equipment, agricultural tractors, generator sets, marine propulsion, and material handling equipment. While the 6D24 engine is commonly used in Mitsubishi heavy machinery, this part is a direct replacement for the original bearing set.

Key Features & Benefits

• OEM Specification: Precision engineered to meet the exact dimensions and material hardness of the original Mitsubishi part (ME994419), ensuring a perfect fit and reliable performance.
• STD (Standard Size): This is a standard size bearing, ideal for engines with crankshaft journals that are still within factory tolerances. No undersize machining is required.
• Durable Construction: Manufactured from high-strength steel with a specialized anti-friction lining to withstand high loads and operating temperatures found in diesel engines.
• Improved Oil Film Retention: The bearing surface is designed to maintain a stable oil film, reducing friction and preventing metal-to-metal contact for extended engine life.
• Enhanced Wear Resistance: Built to resist fatigue and wear from constant high-pressure cycles, providing long service intervals.
• Rigorous Quality Control: Each bearing is inspected for dimensional accuracy and surface finish to guarantee consistent quality.

Technical Specifications

OEM Cross-Reference

This connecting rod bearing is a direct replacement for the following OEM part numbers:

• Mitsubishi: ME994419
• Alternative Reference: 6D24-11-000 (common casting number)

Note: Always verify your engine’s specific requirements. This is a standard size bearing. If your crankshaft journal has been ground, you may require an undersize bearing (e.g., 0.25mm, 0.50mm).

Compatibility

This bearing is commonly used for the following applications. Please confirm your specific engine model and serial number before purchase.

• Engine: Mitsubishi 6D24 (Naturally Aspirated and Turbocharged variants)
• Common Applications:
  • Construction: Excavators, Bulldozers, Wheel Loaders
  • Industrial: Forklifts, Generators, Compressors
  • Agricultural: Tractors, Harvesters
  • Marine: Auxiliary engines, Pumps
  • Material Handling: Cranes, Reach Stackers

FAQ

Q1: How do I confirm this bearing is the correct size for my 6D24 engine?

A: This is a STD (Standard) size bearing. You must first measure the diameter of your crankshaft connecting rod journal. If it is within factory specifications (typically 70mm or 72mm for 6D24, but verify with your service manual), this bearing is correct. If the journal has been ground undersize, you will need a corresponding undersize bearing (e.g., 0.25mm, 0.50mm). Always use a micrometer for accurate measurement.

Q2: What is the installation procedure for this bearing?

A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Clean the connecting rod and cap mating surfaces. 2) Lubricate the bearing shells with clean engine oil. 3) Align the bearing tang with the notch in the rod and cap. 4) Torque the connecting rod bolts to the manufacturer’s specifications (usually in a specific sequence and torque value, e.g., 147 Nm + 90° turn for 6D24). 5) Always check bearing clearance using Plastigage before final assembly.

Q3: What is the recommended maintenance interval for these bearings?

A: Connecting rod bearings are wear items. In a well-maintained engine, they can last for thousands of hours. However, they should be inspected during any major engine overhaul or if you notice symptoms like low oil pressure, knocking noises from the bottom end, or metallic debris in the oil filter. Using high-quality engine oil and changing it at the recommended intervals is critical for bearing longevity.
