Cylinder Seal Kit BUCKET 80x120mm (fits JCB) - GMOVE 6900/0801
High-quality bucket cylinder seal repair kit (BUCKET) by GMOVE, part number 6900/0801. The kit is dedicated to professional JCB tracked and wheeled excavators. Designed for cylinders with an internal cylinder diameter of 120 mm and a rod diameter of 80 mm. The use of precisely manufactured, modern GMOVE seals guarantees the restoration of full efficiency to the hydraulic system, effectively eliminates leaks, and ensures the maintenance of optimal working pressure of the machine while operating the bucket in difficult ground conditions.
High resistance and durability: GMOVE seal kits are manufactured from selected, high-grade materials (polyurethane, Teflon, NBR) resistant to extremely high pressures, temperature fluctuations, and contaminants occurring in hydraulic systems. The specialized profile of the wiper and sealing rings provides maximum protection against the ingress of dust, mud, and sand into the bucket cylinder, which, due to its location on the arm, operates in the most dirt-exposed conditions.

Workshop Tip: A bucket cylinder leak is often a warning signal. Due to its direct proximity to the digging zone, this cylinder is the most exposed to mechanical damage from the outside.
Golden rules for hydraulic cylinder regeneration:
1. Rod surface evaluation: Before installing a new seal pack, carefully inspect the chrome rod under strong light. Even the smallest stone impacts or scratches can destroy new wiper seals after just a few hours of operation.
2. Absolute cleanliness (sterility): Perform the regeneration on a clean workbench. Use lint-free wipes and wash the components in dedicated cleaners. No hydraulic pump in the machine will forgive quartz or dirt inside the cylinder.
3. Careful seal installation: Avoid using sharp tools (e.g., screwdrivers) to press in polyurethane seals. Any nicks on the seal lip will lead to direct leaks. Before finally inserting the rod, generously lubricate the gland and seals with clean hydraulic oil.
