DIPPER Cylinder Seal Kit 160x110mm (fits JCB) - GMOVE 903/21061
High-quality dipper arm cylinder seal repair kit by GMOVE, part number 903/21061. The kit is dedicated to heavy JCB tracked excavators. Designed for cylinders with an internal cylinder diameter of 160 mm and a rod diameter of 110 mm. The use of precisely manufactured, modern GMOVE seals guarantees the restoration of full efficiency of the hydraulic system, effectively eliminates internal and external leaks, and ensures the maintenance of the machine's optimal working pressure.
High resistance and durability: GMOVE seal kits are manufactured from selected, high-grade materials (polyurethane, Teflon, NBR) resistant to high pressures, extreme temperatures, and contaminants that may appear in the system. The specialized profile of the wiper and sealing rings provides maximum protection against dirt entering the cylinder, protecting it from scratches and costly failure.

Workshop Tip: A cylinder leak is often just a symptom of a deeper problem. Before installing new seals, carefully verify the condition of the remaining hydraulic components.
Golden rules for hydraulic cylinder regeneration:
1. Rod surface evaluation: Before installing the seal pack, carefully inspect the chrome rod under strong light. Even minor scratches that can be felt with a fingernail, corrosion pitting, or impacts will cause the new seals to be destroyed after just a few hours of operation.
2. Absolute cleanliness (sterility): Perform the regeneration on a clean workbench. Use lint-free wipes. Wash the components in special cleaners. One grain of quartz in the system is a death sentence for the control valve and hydraulic pump.
3. Careful seal installation: Avoid using sharp tools (e.g., screwdrivers) to press in polyurethane seals. Any nicks on the seal lip lead to direct leaks. Before finally inserting the rod, generously lubricate the gland and seals with clean hydraulic oil.
