6BD1 T173H Thrust Washer for Isuzu Diesel Engine Excavator & Truck Applications

Product Details

Product Overview

This is a genuine T173H thrust washer, specifically designed for the Isuzu 6BD1 diesel engine. As a critical component in the engine’s bottom end assembly, this thrust washer manages the axial end-play of the crankshaft, ensuring precise alignment and preventing damaging contact between rotating and stationary parts. Commonly applied in excavator and heavy-duty truck configurations, this part is essential for maintaining the longevity and reliability of your Isuzu power unit.

Sourced directly from Japan, this thrust washer meets the exacting specifications of the original equipment manufacturer (OEM). Choosing a genuine part like this T173H model guarantees the correct material composition and dimensional accuracy, which are vital for proper oil clearance and load distribution. This component is a direct replacement for worn washers in 6BD1 engines, helping to restore original performance and prevent premature engine failure.

Key Features & Benefits

• Genuine OEM Quality: This is a genuine part, not an aftermarket alternative, ensuring a perfect fit and consistent performance with your 6BD1 engine specifications.
• Precise Axial Control: The thrust washer is engineered to maintain the correct crankshaft end-play, reducing vibration and wear on main bearings and the crankshaft itself.
• Durable Material Composition: Manufactured from high-grade materials to withstand the high thrust loads generated during excavator and truck operation, providing a long-lasting service life.
• Engineered for Heavy-Duty Applications: Specifically designed for the demanding environments of excavators and trucks, where engine stress and load cycles are extreme.
• Reduces Downtime: Replacing a worn thrust washer with this genuine T173H unit prevents more serious internal engine damage, saving on costly repairs and operational downtime.
• Direct Replacement: Designed as a direct swap for the original part, simplifying the rebuild process and reducing installation time for mechanics.

FAQ

Q: How can I be sure this T173H thrust washer fits my Isuzu 6BD1 engine?
A: The part number T173H is the standard thrust washer for the 6BD1 engine block. To confirm fitment, we recommend checking your engine’s serial number against the parts catalog or visually comparing the old washer’s shape and dimensions (inner diameter, outer diameter, and thickness) to the T173H specifications. If you have an unusual 6BD1 variant, please contact us with your engine details for verification.

Q: What are the signs of a worn thrust washer in a 6BD1 engine?
A: The most common symptom is excessive crankshaft end-play, which can be felt as a knocking sound from the bottom of the engine, especially when the clutch is engaged or disengaged (in truck applications) or when the engine is lugged. Other signs include oil pressure fluctuations and increased vibration. If you suspect wear, it is critical to replace the thrust washer immediately to prevent contact between the crankshaft web and the block.

Q: Can I install this thrust washer without removing the engine?
A: While it is possible in some chassis to replace the thrust washer by removing the oil pan and the rear main bearing cap, it is a complex procedure. The crankshaft must be carefully pried forward to allow the old washer to be removed and the new one inserted. For excavators with tight engine bays, it is often more practical to remove the engine. We strongly recommend this work be performed by a qualified diesel mechanic to ensure correct clearance and prevent damage to the new part or the crankshaft.
