Excavator Connecting Rod Bearing 1-12271072-0 1-12271072-1 1122710721 1122710720 for ISUZU Engine

Product Details

Product Overview

This high-quality connecting rod bearing set, identified by part numbers 1-12271072-0 and 1-12271072-1 (also listed as 1122710721 and 1122710720), is a critical component designed for precision fitment in specific ISUZU diesel engines commonly used in excavators and heavy trucks. As a genuine OEM-grade component, this METAL KIT ensures the tight tolerances required for optimal crankshaft support and rod alignment.

Sourced from Japan, this bearing set is engineered to withstand the high loads and thermal stress of heavy-duty earthmoving equipment. While primarily identified for ISUZU applications, we recommend verifying compatibility with your specific engine serial number and model to ensure a perfect fit. This part is essential for maintaining oil clearance and preventing premature engine wear.

Key Features & Benefits

• OEM-Grade Precision: Manufactured to genuine OEM specifications (1-12271072-0/1) for exact clearance and crush height, ensuring reliable oil film maintenance.
• Long-Lasting Durability: Built with advanced tri-metal or bi-metal layers to resist fatigue, corrosion, and high-impact loads common in excavator operation.
• Japan-Sourced Quality: Engineered and produced in Japan, adhering to strict manufacturing standards for dimensional accuracy and material integrity.
• Enhanced Engine Protection: Reduces friction between the connecting rod and crankshaft journal, extending the life of both components and the overall engine.
• Direct Replacement Fit: Designed as a direct swap for worn bearings in ISUZU engines, minimizing downtime during overhaul or repair.
• Comprehensive Part Identification: Supplied with multiple cross-reference numbers (1122710721, 1122710720) for easy verification against your existing parts.
• 6-Month Warranty Coverage: Backed by a standard 6-month warranty against manufacturing defects, providing peace of mind for your rebuild project.

Technical Specifications

OEM Cross-Reference

This connecting rod bearing set is a direct replacement for the following OEM and original equipment part numbers. Use these references to confirm compatibility with your existing engine parts catalog.

• Primary OEM Numbers: 1-12271072-0, 1-12271072-1

FAQ

Q: How do I confirm these bearings will fit my ISUZU engine?
A: First, locate the existing part number on your old bearing shell (usually stamped on the back). If it matches 1-12271072-0, 1-12271072-1, 1122710721, or 1122710720, they are a direct fit. If you only have an engine model number, please contact us with that information for cross-verification.

Q: What is the recommended installation procedure for these bearings?
A: Installation should be performed by a qualified diesel mechanic. Ensure the bearing bore and crankshaft journal are clean and free of debris. Apply clean engine oil to the bearing surface during installation. Use a plastigage kit to verify oil clearance is within the engine manufacturer’s specifications. Never mix old and new bearings.

Q: Are these bearings suitable for a full engine rebuild kit?
A: Yes, these connecting rod bearings are a standard component in many ISUZU engine overhaul kits. For a complete rebuild, you would typically also require main bearings, thrust washers, piston rings, and gaskets. We can assist in sourcing additional components to match your bearing set.
