6810717: Clamp Hydraulic Cylinder Seal Kit for Bobcat Excavator 337G, 337WG, 341G
6810717 Clamp Cylinder Seal Kit — Product Overview
The 6810717 Clamp Cylinder Seal Kit is a precision aftermarket replacement for Bobcat 337G, 337WG, and 341G excavators. Designed for the clamp cylinder with 2″ rod and 2-3/4″ bore dimensions, this kit matches OEM cylinder specification 6808069 (S/N: 234611001-Up).
The clamp cylinder on the 337G/341G platform is used for hydraulic attachment clamping — securing buckets, breakers, grapples, and other work tools to the excavator’s quick coupler. Unlike boom or arm cylinders that see dynamic actuation, the clamp cylinder primarily operates in a static holding mode, maintaining high clamping force for extended periods. Seal failure manifests as clamp pressure loss (the attachment loosens during operation), creating a critical safety hazard in heavy construction and demolition applications.
The 6810717 kit uses polyurethane rod seals engineered for sustained holding pressure and NBR static seals etc for reliable containment under constant clamp load. DJF Seals supplies this kit at factory-direct wholesale pricing.
