SEAL KIT - HYDRAULIC CYLINDER (Komatsu KO4906101)

A damaged seal kit can allow hydraulic fluid to bypass the piston, reducing cylinder force and causing slow or erratic movement. The Komatsu catalog reference for this aftermarket replacement part is KO4906101. This seal kit contains the elastomeric rings and wiper seals that contain pressurized fluid within the cylinder bore. When seals degrade, external leakage can create slippery surfaces and fluid loss. Keeping a seal kit in sound condition helps maintain consistent cylinder extension and retraction speeds. The item ships at approximately 0.014 pounds. Verify the serial number or application, then call (562) 693-7748.

Part number variants: KO4906101, ko4906101
