Product Overview

This is a genuine, high-quality main crankshaft bearing set engineered specifically for the 3D82E excavator engine, featuring the M418A designation and a critical oversize of +0.25mm (+25). Designed for precision engine rebuilds, this bearing set restores optimal oil clearance and crankshaft alignment. We supply directly to workshops, distributors, and heavy machinery operators worldwide, with established logistics to major markets across North America, Europe, the Middle East, and Asia-Pacific.

Key Features & Benefits

• Genuine Quality & Precise Fit: Manufactured to exact OEM specifications, ensuring perfect compatibility with the 3D82E engine block and crankshaft for a reliable, long-lasting rebuild.
• Oversize for Engine Salvage: The +0.25mm oversize is essential for engines where the crankshaft journal has been machined (ground) to remove scoring or wear, allowing for a cost-effective repair versus full replacement.
• Enhanced Durability & Load Capacity: Constructed from high-grade materials with a precision-aligned bearing surface to withstand extreme pressures and rotational forces within the excavator engine.
• Optimal Oil Film Maintenance: Precision engineering ensures correct oil clearance, which is vital for maintaining hydrodynamic lubrication, reducing friction, and preventing premature wear.
• Complete Bearing Set: Sold as a full set for all main bearing positions, guaranteeing uniform quality and performance across the entire crankshaft support system.

Technical Specifications

OEM Cross-Reference

This genuine bearing set corresponds directly to the OEM part number for the specified oversize. For verification, please cross-reference with the engine’s technical documentation using the key identifiers: Engine 3D82E and Bearing Code M418A (+0.25).

Compatibility

Primary Application: This main bearing set is specifically designed for the 3D82E diesel engine.

Typical Vehicle/Machine Use: Commonly found in excavators and other heavy construction machinery utilizing the 3D82E power plant. Always verify your engine model and the required bearing oversize from your machine’s service manual or by measuring the machined crankshaft before ordering.

FAQ

Q1: How do I know if I need an oversize bearing, and which size to order?
A1: Oversize bearings are required after the engine crankshaft has been machined (“ground”) to restore a smooth surface on the journal. The required oversize (e.g., +0.25mm, +0.50mm) is determined by the machinist who performs the crankshaft grinding. You must measure the finished crankshaft journals or obtain the specification from the machine shop to select the correct bearing.

Q2: Is this a complete set for all main bearing caps?
A2: Yes, this product is sold as a complete main bearing set. It includes all the upper and lower bearing shells required to install the crankshaft in the engine block for the 3D82E engine. Always install bearings as a complete set to ensure uniform clearance and performance.

Q3: What is the critical step during installation to ensure longevity?
A3: The most critical steps are cleanliness and proper torque procedure. Ensure all engine block and bearing surfaces are impeccably clean. Always use a calibrated torque wrench and follow the manufacturer’s specified sequence and torque values when tightening the main bearing caps. Incorrect torque can distort the bearings or block, leading to rapid failure.
