Cylinder Liner Sleeve DJCXYSM Set for Cummins 4BT and 6BT 102mm Chrome

Description

Product Overview

The DJCXYSM Cylinder Liner Sleeve set is a premium replacement component designed specifically for Cummins 4BT and 6BT engines with a 102mm bore. Each sleeve is crafted from high‑strength alloy and finished with a chrome coating that offers exceptional wear resistance, corrosion protection, and heat dissipation. The set includes two matching liners, each precisely machined to OEM dimensions, ensuring a seamless fit that restores original compression ratios and engine performance. The chrome surface reduces friction, promotes smoother piston movement, and extends service intervals, making it an ideal choice for both professional workshops and dedicated hobbyists.

Manufactured by DJCXYSM, a reputable brand known for durable automotive parts, the liners meet rigorous quality standards and are tested for dimensional accuracy, hardness, and surface finish. The product is listed under ASIN B0DMJ9JSSJ and holds a Best Sellers Rank of #32 in the Automotive Replacement Engine Piston Liners category, reflecting strong market acceptance and reliability. With a price of $175.00, the set offers a cost‑effective solution without compromising on quality or longevity.

Usage

These cylinder liner sleeves are intended for use in medium‑duty diesel engines, particularly in agricultural, construction, and light‑commercial applications where Cummins 4BT and 6BT powerplants are common. The liners are suitable for both new engine builds and overhauls, providing a reliable foundation for piston rings and ensuring optimal sealing. Installation requires standard engine disassembly procedures, but the precise tolerances of the DJCXYSM sleeves simplify the reassembly process, reducing the risk of misalignment or uneven wear.

When installing, it is essential to verify the part numbers (3904166 and 3900396) against the engine’s service manual to avoid mismatches. The chrome coating also facilitates easier cleaning during maintenance, as oil and carbon deposits are less likely to adhere stubbornly. For best results, follow the recommended torque specifications and use a compatible piston ring set that matches the liner dimensions.

FAQ

What engines are compatible with this liner set?

The DJCXYSM Cylinder Liner Sleeve set is compatible with Cummins 4BT and 6BT engines that have a 102mm bore. It is commonly used in agricultural tractors, construction equipment, and light‑commercial vehicles that employ these engine models.

Do I need to replace piston rings when installing new liners?

While the liners are designed to work with existing piston rings, we recommend inspecting the rings for wear and replacing them if they show signs of scoring or loss of tension. Using a matching ring set ensures optimal sealing and performance.

How do I verify that I have the correct part numbers?

Check the engine’s service manual or the existing liner’s stamping for the part numbers 3904166 and 3900396. If you are unsure, you can provide a photo of the engine model and nameplate to our support team, and we will confirm compatibility before you purchase.

Can the chrome coating be repaired if it gets damaged?

The chrome coating is integral to the liner’s wear‑resistant properties. Minor surface scratches are normal and do not affect performance, but significant damage may require replacement of the liner. Our technical support can assess the condition and advise on the best course of action.
