Product Details:
Product Introduction
The 3928797 truck cylinder block from Diron Parts is built for heavy-duty diesel engine service. It is commonly used in Cummins 6BT / 6B5.9 / 6BT5.9 engine applications and is suitable for engine rebuilders, repair workshops, parts distributors, and fleet maintenance suppliers.
Aftermarket Replacement Part
This cylinder block is an aftermarket replacement part, not an original branded component. It is produced to support repair and replacement needs for compatible diesel engine applications. Buyers should compare the part number, casting details, engine configuration, and installation requirements before confirming an order.
Durable Cast-Iron Construction
The engine block uses a strong cast-iron body to support high-load diesel engine operation. The black-gray cast surface helps provide a clean replacement-part appearance, while the machined surfaces, bolt holes, ports, and mounting points are designed for professional engine assembly work.
Compatible Engine Applications
This product is suitable for Cummins 6BT-series 5.9L diesel engine applications where part number 3928797 or related reference part numbers match the required engine block. Common reference numbers include 3935943, 3939313, 3939314, 3965763, and 3971039.
Recommended Use
The cylinder block can be used for truck diesel engine overhaul, engine repair projects, replacement-part inventory, workshop service supply, and export aftermarket parts programs. It is recommended for customers who need a replacement block for compatible 6-cylinder diesel engine rebuilds.
Ordering Notes
Before purchasing, please provide the engine model, required part number, casting number if available, and clear photos of the original block. This helps confirm compatibility and reduces the risk of incorrect fitment. Technical confirmation is especially important for rebuilt engines, modified engine configurations, and regional equipment variations.
