Technical Specifications

OEM Cross-Reference

This cylinder liner is a direct cross-reference for the following Isuzu genuine part numbers. Please verify your existing part number against the list below to confirm compatibility:

• 8-97176-693-0 (Primary OEM Number)
• 8-94462-130-0 (Alternative OEM Number)
• 8-94110-144-0 (Alternative OEM Number)

These numbers correspond to the standard size cylinder liner used in the 4JA1 engine family. If your engine uses a different suffix or variant (e.g., 0.25 or 0.50 oversize), please consult our technical team for matching oversized options.

Compatibility

This cylinder liner is specifically designed for the Isuzu 4JA1 diesel engine. It is commonly used for the following types of heavy equipment and vehicles, where the 4JA1 engine is installed as the power unit:

• Excavators: Mini and compact excavators (e.g., Isuzu-based models)
• Trucks: Light and medium-duty trucks
• Forklifts: Diesel counterbalance forklifts
• Bulldozers: Small to mid-size dozers
• Buses: Light commercial buses and minibuses
• Loaders: Skid steer and compact wheel loaders

Note: Fitment is inferred based on the engine model. Always verify the specific engine block casting number and liner type (dry/wet) before ordering.

FAQ

Q1: How do I confirm that this liner fits my specific Isuzu 4JA1 engine?
A: First, locate the existing part number on your old liner (e.g., 8-97176-693-0). If it matches one of the numbers listed, it is a direct fit. Additionally, measure the inner diameter of your cylinder bore. This liner is OEM standard size. If your engine requires an oversize liner (e.g., 0.25mm or 0.50mm), this standard liner will not fit without re-boring the block. For engines with unknown history, we recommend consulting an engine rebuilder.

Q2: What is the recommended installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. For dry liners (typical in 4JA1 engines), the block bore must be clean, dry, and free of burrs. The liner should be pressed in using a proper press tool, not hammered. After installation, check for proper protrusion above the block deck (typically 0.02-0.10mm). Honing or deglazing may be required after installation to achieve the correct crosshatch pattern for new piston rings.

Q3: Can I use this liner with a rebuilt or remanufactured 4JA1 engine?
A: Yes, this liner is an ideal replacement for rebuilt engines. However, always verify the block’s condition first. If the block has been previously re-bored to an oversize, this standard liner will not fit. Also, ensure that the corresponding pistons and rings are matched to this liner’s bore size. We recommend replacing the piston rings and optionally the pistons when installing new liners to ensure optimal sealing and performance.
