Product Details

Product Overview

This high-quality Cylinder Liner is specifically engineered for the Cummins K19, QSK19, and KTA19 diesel engine platforms. As a critical component within the engine block, this liner provides the hard-wearing surface against which the piston rings seal, ensuring optimal compression and oil control. Designed to OEM specifications, it is a direct replacement for multiple original part numbers, offering a reliable solution for engine rebuilds and overhauls.

Ideal for heavy-duty applications ranging from construction equipment to industrial power units, this cylinder liner is manufactured to meet the rigorous demands of continuous operation. It is commonly used in machinery where the K19 engine series is the prime mover, including excavators, bulldozers, and large trucks. This part provides a perfect balance of durability and precision for restoring engine performance.

Key Features & Benefits

• OEM Specification Fitment: Manufactured to match the exact dimensions and tolerances of the original Cummins parts, ensuring a precise fit within the engine block without the need for modification.
• Enhanced Durability: Constructed from high-strength alloy cast iron, the liner is designed to withstand extreme combustion pressures, high temperatures, and the constant friction of piston movement.
• Improved Wear Resistance: The hardened internal bore surface reduces wear rates, extending the service life of both the liner and the piston rings, which minimizes downtime for maintenance.
• Reliable Oil Control: The precision-honed finish ensures proper oil film retention for lubrication while preventing excessive oil consumption, contributing to cleaner combustion and lower operating costs.
• Comprehensive Cross-Reference: Directly replaces a wide range of OEM part numbers (4024767, 3028434, 3028122, 4009220, 4308809, 4371769, 3202240), simplifying inventory management for service centers.
• Rigorous Quality Control: Each liner undergoes dimensional and material hardness checks to guarantee consistent quality and reliable performance in the field.

FAQ

Q1: How can I confirm this cylinder liner will fit my Cummins K19 engine?
A: You should verify the existing part number on your old liner. This product is a direct replacement for OEM numbers 4024767, 3028434, 3028122, 4009220, 4308809, 4371769, and 3202240. If your engine model is K19, QSK19, or KTA19, this liner is the correct component. We recommend measuring the bore diameter and flange height of your old part to confirm compatibility.

Q2: What is the recommended installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. The cylinder bore in the engine block must be thoroughly cleaned and inspected for damage. Ensure the liner is free of debris. For wet liners, new O-rings or seals must be installed. For dry liners, a light press fit is standard. Always lubricate the liner bore and piston rings during assembly and follow the engine manufacturer’s torque specifications for the cylinder head.

Q3: What maintenance can I perform to maximize the lifespan of these cylinder liners?
A: The longevity of the liners is directly linked to proper engine maintenance. Use high-quality engine oil and filters, and adhere to the recommended oil change intervals. Keep the cooling system in good condition with proper coolant mixture to prevent overheating and cavitation. Regularly inspect and replace air filters to prevent abrasive dust from entering the cylinders, which accelerates liner and ring wear.
