6BG1 6BD1 6BF1 Thrust Washer 1-11680001-1 1116800010 for Isuzu Engine Repair

Product Details

Product Overview

This high-precision thrust washer, identified by part numbers 1-11680001-1 and 1116800010, is a critical component designed for the Isuzu 6BG1, 6BD1, and 6BF1 diesel engine series. As an essential part of the engine’s lower end, this thrust washer controls the axial movement (end play) of the crankshaft, ensuring optimal clearance and preventing metal-to-metal contact between the rotating crankshaft and the stationary engine block.

Manufactured to meet OEM specifications, this thrust washer is a direct-fit repair part commonly utilized in heavy-duty equipment such as excavators, loaders, bulldozers, forklifts, trucks, and buses powered by these specific Isuzu engine models. The use of a correctly sized and durable thrust washer is vital for maintaining bearing preload and extending the service life of the entire rotating assembly during an overhaul or rebuild.

Key Features & Benefits

• Precision Fitment: Machined to OEM size specifications (1-11680001-1 / 1116800010) to guarantee correct crankshaft end-play clearance and eliminate guesswork during engine assembly.
• Durable Construction: Manufactured from high-grade, wear-resistant material to withstand the high axial loads and frictional forces inherent in heavy-duty diesel engine operation.
• Critical Engine Protection: Effectively prevents crankshaft walk and protects the main bearing thrust faces from premature wear, reducing the risk of catastrophic engine failure.
• Reliable Sourcing: Supplied by, ensuring a consistent quality standard for aftermarket engine repair components suitable for industrial and commercial vehicle applications.
• Comprehensive Application: Specifically engineered for the Isuzu 6BG1, 6BD1, and 6BF1 engine platforms, making it a versatile stock item for workshops servicing a range of Japanese heavy equipment.

Technical Specifications

OEM Cross-Reference

This thrust washer directly replaces the following original equipment manufacturer (OEM) part numbers, ensuring compatibility with genuine Isuzu specifications:

• Isuzu OEM Number: 1-11680001-1
• Alternative Number: 1116800010

Note: Always verify the exact part number stamped on your original component before ordering to ensure a correct match.

Compatibility

This thrust washer is specifically designed for the Isuzu 6BG1, 6BD1, and 6BF1 diesel engine families. It is commonly used for repair and overhaul in the following equipment types:

• Excavators: Commonly found in Hitachi, Sumitomo, Kobelco, and other excavators utilizing these Isuzu engines.
• Loaders & Bulldozers: Suitable for wheel loaders and crawler dozers powered by the 6BD1 or 6BG1.
• Forklifts: Used in heavy-capacity forklifts from brands like Toyota, TCM, and Nissan.
• Trucks & Buses: Compatible with Isuzu Forward, Elf (for larger models), and other medium-duty truck chassis.

Important: This part is an engine internal component. Fitment depends on the specific engine model, not the vehicle chassis. Always confirm the engine model (6BG1, 6BD1, 6BF1) before purchase.

FAQ

Q: How do I confirm this thrust washer is correct for my engine?
A: The most reliable method is to remove the old thrust washer and check the part number stamped on it. If it reads 1-11680001-1 or 1116800010, this part is a direct replacement. You should also visually confirm the engine model plate is labeled 6BG1, 6BD1, or 6BF1.

Q: Should I replace the thrust washer during a standard engine overhaul?
A: Yes, it is highly recommended. The thrust washer is a wear item that controls crankshaft end-play. Reusing an old washer with a reground crankshaft or new main bearings can lead to incorrect clearances, causing premature bearing failure. Always replace it as part of a comprehensive engine rebuild kit.

Q: What is the correct way to install this thrust washer?
A: The thrust washer has an oil groove on one side. This grooved side must face the rotating crankshaft thrust face to ensure proper oil lubrication. The flat, non-grooved side faces the engine block. After installation, always check the crankshaft end-play with a dial indicator to ensure it is within the service manual specifications for your specific 6BG1/6BD1/6BF1 engine.
