Product Details
Product Overview
This high-quality Cylinder Liner is a precision-engineered replacement component designed for Komatsu diesel engines. Specifically manufactured to match OEM specifications, the part numbers 6207-21-2110 and 6207-21-2120 correspond to the liners used in the Komatsu 4D95, 6D95, 6D95L, S6D95L, and SA6D95L engine series. These engines are commonly found in heavy construction equipment such as excavators, bulldozers, and loaders, as well as in industrial machinery like forklifts and trucks.
As a critical part of the engine block, this cylinder liner provides the hard-wearing surface for the piston to travel. Our product is manufactured to strict OEM dimensional standards (OEM Size), ensuring a proper fit and reliable performance. This component is an ideal solution for equipment maintenance and engine overhaul projects where restoring cylinder compression and reducing oil consumption is essential.
Key Features & Benefits
Precision Fit: Machined to exact OEM size specifications (6207-21-2110 / 6207-21-2120) to ensure seamless installation into the engine block without modification.
Durable Construction: Manufactured from high-grade cast iron with a hardened inner surface to resist wear from piston ring friction, ensuring a long service life.
Enhanced Engine Performance: Restores proper cylinder compression and reduces oil blow-by, helping to recover lost engine power and improve fuel efficiency.
Comprehensive Compatibility: Designed for a wide range of Komatsu engine models (4D95, 6D95, S6D95L, SA6D95L), making it a versatile stock item for workshops.
Rigorous Quality Control: Each liner undergoes strict dimensional inspection and is backed by a 6-month warranty for manufacturing defects.

FAQ
Q1: How do I confirm if this liner fits my Komatsu 6D95 engine? A: Please check the casting number on your old liner. If it reads 6207-21-2110 or 6207-21-2120, this part is a direct replacement. The liners are designed to OEM standard size for the 4D95 and 6D95 engine families.
Q2: What is the recommended installation procedure for this cylinder liner? A: Installation should be performed by a qualified diesel mechanic. Ensure the engine block bore is clean and free of debris. For dry liners, press the liner into the block using a suitable tool to avoid distortion. For wet liners, ensure the O-rings are properly seated. Always check the liner protrusion height after installation to ensure it meets the engine manufacturer’s specifications.
Q3: What is the typical lifespan of this cylinder liner under normal operating conditions? A: The lifespan depends on maintenance, load cycles, and oil quality. With proper engine maintenance and using the correct grade of oil, this liner can last several thousand hours. It is designed to match the durability of the OEM Komatsu part, providing a reliable service life for rebuild applications.
