Connecting Rod Bearing STD for Hino EM100 Engine – Excavator, Forklift, Truck Parts

Product Details

Product Overview

This high-precision connecting rod bearing, sized to Standard (STD) dimensions, is specifically designed for the Hino EM100 diesel engine. As a critical component within the engine’s bottom end assembly, this bearing ensures the proper clearance and oil film thickness required for the connecting rod’s big end to rotate smoothly on the crankshaft journal.

Sourced from, a reputable brand in the Guangdong manufacturing hub, this bearing is a direct replacement for worn or damaged original equipment parts. It is engineered to meet OEM specifications, providing a reliable solution for maintaining engine performance in heavy-duty applications such as excavators, forklifts, loaders, and trucks. Please verify your engine model (EM100) and bearing size (STD) before purchase to confirm fitment.

Key Features & Benefits

• OEM Standard Dimensions: Manufactured to exact OEM size specifications (STD) for a precise interference fit and proper clearance, eliminating the guesswork during engine rebuilds.
• Premium Material Composition: Constructed from high-strength, wear-resistant materials designed to withstand high loads and extreme operating temperatures common in diesel engines.
• Enhanced Durability: Features a specialized overlay that provides excellent embedability for contaminants and superior fatigue resistance, extending the service life of the bearing and the crankshaft.
• Consistent Oil Clearance: Precision-machined to maintain the critical oil clearance between the rod and crankshaft, ensuring adequate lubrication and preventing seizure or knocking.
• Direct Replacement Fit: Engineered as a direct drop-in replacement for the original Hino EM100 connecting rod bearing, simplifying the installation process for mechanics and workshops.
• Rigorous Quality Control: Each batch undergoes outgoing inspection and machinery test reports, ensuring dimensional accuracy and material integrity before shipment.

Technical Specifications

OEM Cross-Reference

This connecting rod bearing is designed as a direct replacement for the original Hino parts used in the EM100 engine series. While a specific OEM part number is not listed in the source data, the bearing is manufactured to match the specifications of the genuine Hino components. For professional buyers, we recommend cross-referencing your existing bearing’s part number (often stamped on the back) or consulting your Hino engine service manual.

Common Reference: This part is typically used where a Hino EM100 connecting rod bearing (STD) is required. If you have a specific OEM number from your existing bearing, please contact us to verify compatibility.

Compatibility

This connecting rod bearing is specifically designed for the Hino EM100 diesel engine. Based on this engine’s application, it is commonly used for maintenance and repair in the following equipment types:

• Excavators
• Forklifts
• Trucks (light to medium duty)
• Loaders and Bulldozers
• Buses
• Other industrial and agricultural machinery powered by the Hino EM100 engine

Important Fitment Note: This is a Standard (STD) size bearing. It is intended for use with a crankshaft journal that is within factory specification and has not been reground. Always measure your crankshaft journal diameter and connecting rod bore to confirm that a standard bearing is correct for your rebuild.

FAQ

Q1: How do I confirm that this STD bearing is the correct size for my Hino EM100 engine?
A: The “STD” (Standard) designation means this bearing is for a crankshaft journal that is at its original factory size and has not been machined. To confirm, you must measure the connecting rod journal diameter on your crankshaft using a micrometer. If the diameter falls within the manufacturer’s standard tolerance range (typically specified in the service manual), this bearing is correct. If the journal is worn or has been reground, you will need an undersize bearing (e.g., 0.25mm, 0.50mm).

Q2: What are the signs of a worn connecting rod bearing that needs replacement?
A: The most common symptom is a low-pitched knocking or rumbling noise from the bottom of the engine, which often becomes louder under load or acceleration. You may also observe low oil pressure on the gauge. During a rebuild, visual signs include copper or aluminum showing through the bearing’s overlay material, scoring, or the bearing being loose in the connecting rod. Never reuse a bearing that shows signs of wear or damage.

Q3: Do I need to replace the main bearings at the same time as the connecting rod bearings?
A: While it is not strictly mandatory, it is highly recommended as a best practice. Both the main bearings and connecting rod bearings wear together over time. Replacing only the rod bearings can introduce an imbalance in oil clearance and oil pressure distribution. For a comprehensive and reliable engine rebuild, we recommend replacing the main bearings, thrust washers, and all seals alongside the connecting rod bearings to ensure uniform performance and longevity.
