Isuzu 6BG1 4 Ring Diesel Engine Rebuild Kits 105mm Piston Replacement 8-97358574-0

Isuzu 6BG1-4R Diesel Engine Piston – Part Number 8-97358574-0

The Isuzu 6BG1-4R engine piston, part number 8-97358574-0, is an important internal component of the diesel engine combustion system. It is designed for compatible Isuzu 6BG1 engine applications and is identified by its four-ring configuration and 105 mm cylinder bore specification.

During engine operation, the piston moves up and down inside the cylinder liner. It receives the pressure generated by the combustion of diesel fuel and transfers this force through the piston pin and connecting rod to the crankshaft. This continuous movement is an essential part of the engine's power-generation process.

The piston must work together with several other engine components, including piston rings, piston pins, cylinder liners, connecting rods, and cylinder heads. Correct dimensional matching is important because the piston operates under repeated mechanical loads, high temperatures, and changing combustion pressures.

For buyers searching for an Isuzu 6BG1 replacement piston, the part number 8-97358574-0 is an important identification reference. It is also listed in some aftermarket catalogues under the alternative number 8973585740. The four-ring design distinguishes it from certain three-ring piston versions, making it important to verify the ring configuration before purchasing.

Five Key Product Features

1. Accurate 6BG1-4R Engine Model and Part Number Identification

This piston is identified by the Isuzu engine model 6BG1-4R and part number 8-97358574-0. Part number identification helps international buyers, distributors, and repair workshops find the required replacement component more efficiently.

In the aftermarket spare parts business, different piston versions can look similar while having different dimensions, ring arrangements, or installation requirements. Using the original reference number helps reduce confusion when comparing supplier catalogues, preparing quotations, and purchasing replacement engine components.

The alternative number 8973585740 can also be included in product searches and purchasing records. Buyers should still confirm the original engine identification and physical specifications before ordering.

2. Four-Ring Piston Design for Engine Sealing and Oil Control

The 6BG1-4R piston is designed with four piston ring grooves. The piston ring assembly plays an important role in maintaining the working conditions inside the cylinder.

Compression rings help seal the combustion chamber and reduce the leakage of high-pressure combustion gases into the crankcase. The oil-control ring assembly helps regulate the lubricating oil film on the cylinder wall, supporting proper lubrication while limiting excessive oil consumption.

The number and dimensions of the rings must match the engine's original piston design. This is particularly important when replacing a three-ring piston with a four-ring version or when purchasing piston rings separately. Buyers should check the ring thickness and groove dimensions to ensure that the replacement components are compatible.

3. 105mm Bore Diameter for Compatible 6BG1 Engine Applications

This piston is listed with a 105 mm bore diameter. Bore diameter is one of the most important specifications when selecting an engine piston because it corresponds to the cylinder bore and determines the dimensional relationship between the piston and cylinder liner.

Correct piston-to-cylinder clearance is essential for reliable engine operation. If the clearance is too small, thermal expansion may cause excessive friction or piston seizure. If the clearance is too large, it may contribute to piston movement, noise, and increased oil consumption.

Before ordering, buyers should confirm whether the engine requires a standard-size piston or an oversize replacement. The actual piston diameter, cylinder liner condition, and manufacturer's clearance requirements should be checked during an engine overhaul.

4. Important Engine Component for Repair and Overhaul

The piston is exposed to repeated combustion pressure, temperature changes, and mechanical movement during engine operation. Over time, wear, overheating, insufficient lubrication, or other engine problems may damage the piston and affect engine performance.

Replacing a damaged or worn piston may be necessary during an engine repair or rebuilding project. However, piston replacement should be considered together with the condition of the cylinder liner, piston rings, piston pin, connecting rod, and related components.

For professional repair workshops, checking these components as a complete assembly helps reduce the risk of repeated maintenance caused by mismatched or worn parts. This piston can therefore be included in compatible Isuzu 6BG1 engine overhaul and maintenance parts procurement.

5. Suitable for Heavy Equipment Parts Distributors and Wholesale Buyers

The 8-97358574-0 piston is relevant to businesses involved in heavy equipment spare parts distribution, diesel engine component wholesale, and excavator engine repair.

For importers and distributors, a clearly identified product number, engine model, bore diameter, and ring configuration make product selection and stock management easier. These details can also be used in product catalogues, quotation documents, online listings, and purchasing databases.

Buyers purchasing in bulk can confirm the required quantity, product packaging, quality requirements, and delivery arrangements with their supplier before placing an order. Related engine overhaul components, such as piston rings, cylinder liners, gaskets, and piston pins, can also be checked together to support a more complete procurement plan.

Product Applications

This piston is listed for compatible Isuzu 6BG1-4R engine applications. Supplier catalogues also associate this part number with selected Hitachi excavator applications, including SH220-3 and ZX200/ZX230 variants. Actual compatibility must be verified by engine serial number and original part specifications.
