Isuzu 6HK1 Cylinder Block 8-98023-526-0 for Excavator & Truck Engine Parts

Product Details

Product Overview

This cylinder block is a direct replacement component specifically designed for the Isuzu 6HK1 diesel engine. The 6HK1 is a heavy-duty, 7.8-liter inline 6-cylinder engine widely used in construction machinery, material handling equipment, and commercial vehicles. This cylinder block serves as the main structural foundation for the engine, housing the cylinders, crankshaft, and other critical rotating and reciprocating components.

Manufactured to OEM specifications (OEM Size), this block ensures a precise fit and reliable performance for your engine rebuild or replacement project. It is commonly applied in excavators, bulldozers, forklifts, loaders, trucks, and buses powered by the Isuzu 6HK1 engine family. Please verify your engine model and serial number to confirm compatibility before purchase.

Key Features & Benefits

• Robust Cast Iron Construction: Built from high-grade cast iron to withstand the extreme pressures and temperatures of diesel combustion, providing long service life in demanding applications.
• Precision Machined Surfaces: All mating surfaces, cylinder bores, and bearing journals are precision-machined to ensure correct clearances and oil sealing for optimal engine performance.
• Comprehensive Fitment: Designed for a wide range of heavy equipment including excavators, wheel loaders, bulldozers, and commercial trucks, making it a versatile stock item for repair shops.
• Rigorous Quality Control: Each block undergoes dimensional inspection and pressure testing to verify structural integrity before shipment, reducing the risk of installation failure.
• Reliable Supply Chain: Sourced from a verified manufacturer with a warranty period of 6 months, providing peace of mind for your capital investment.

Technical Specifications

OEM Cross-Reference

This cylinder block is designed as a direct replacement for the following original Isuzu part number:

• Isuzu OEM Number: 8-98023-526-0

Note: This part is a direct replacement for the specific 6HK1 engine block casting. It is not a generic cross-reference for other Isuzu engine families (e.g., 4HK1, 6WG1). Always verify your existing part number against the OEM number listed above.

Compatibility

This cylinder block is specifically designed for the Isuzu 6HK1 diesel engine. It is commonly used for the following applications and equipment types:

• Excavators: Various models from Hitachi, Sumitomo, and Kobelco using the 6HK1 engine.
• Wheel Loaders & Bulldozers: Heavy equipment requiring the 6HK1’s torque and power.
• Forklifts: Large capacity forklifts (10-16 ton range) powered by the 6HK1.
• Trucks & Buses: Isuzu Forward (F-Series) and other medium-duty commercial vehicles.

Important Fitment Note: The 6HK1 engine has multiple variants (e.g., 6HK1-TC, 6HK1-TCC). While this block is the standard casting, verify your engine’s serial number and block casting number to ensure exact match for core plug and main bearing cap configurations.

FAQ

Q1: Is this a complete short block or just the bare casting?
This is a bare cylinder block casting. It includes the main casting with machined cylinder bores, but it does not include internal components such as pistons, liners, crankshaft, camshaft, or main bearings. You will need to transfer these components from your original engine or purchase them separately for a full rebuild.

Q2: How can I confirm this block fits my specific 6HK1 engine?
To confirm fitment, please check the casting number on the side of your original block. It should be 8-98023-526-0 or a very similar variant. Also, verify the number of main bearing caps (typically 7) and the location of the oil filter and fuel injection pump mounting pads. If your engine has a different block casting number, please contact us with your engine serial number for cross-referencing.

Q3: What preparation is required before installing this new block?
Before installation, we recommend the following steps: 1) Clean the block thoroughly to remove any shipping preservatives. 2) Check all core plug (freeze plug) installations are secure. 3) Verify main bearing bore alignment using a torque plate if possible. 4) Install new camshaft bearings (if not pre-installed). 5) Use a high-quality assembly lube on all rotating parts. We strongly advise having the block checked by a professional machine shop before final assembly to ensure all tolerances are within spec.
