The 904-09400 Seal Kit is a hydraulic clamp seal designed for the backhoe sideshift locking system of JCB 3CX and 4CX backhoe loaders. This seal provides critical oil sealing for the hydraulic clamp pistons that secure the backhoe assembly to the sideshift carriage. Replacing a worn seal prevents pressure loss and lateral slipping of the backhoe during excavation, completely stopping oil leaks and safely locking the entire system in place.

Product Overview
The 904-09400 Seal Kit is specifically engineered for JCB backhoe loader sideshift clamp systems. This seal is a key component that maintains oil pressure in the rams that lock the rear arm’s sideshift. If your excavator arm drifts sideways during operation, doesn’t hold its position, and you see oil leaks around the rams, these are classic symptoms of a worn seal.
This failure leads to a dangerous “floating” of the arm, which prevents precise work and accelerates wear on the slide pads. Replacing the seal is an inexpensive repair that prevents much more costly failures in the future.
