991/00130 JCB Rear Boom / Dipper Cylinder Seal Repair Kit (100 mm x 60 mm)

🔹 Product Description The product with part number 991/00130 is a heavy-duty hydraulic cylinder seal repair kit manufactured to Original/OEM standards, specifically designed for the main cylinders of JCB backhoe loaders. It is engineered for cylinders with a 100 mm bore (internal diameter) and a 60 mm rod (shaft), typically found in boom and dipper functions. The set includes high-pressure oil seals, dust wipers, piston seals, and all necessary O-rings. It maintains the machine's breakout force by preventing oil bypass and external leaks under extreme excavation pressures.

🚀 Advantages:

⚡ Maximum Sealing Efficiency: High-quality reinforced polyurethane components effectively stop oil leaks even under the heaviest excavation loads and peak hydraulic pressures.

🛡️ Superior Rod Protection: The heavy-duty wiper seal prevents dust and mud from entering the cylinder, protecting the 60 mm rod from scoring and reducing barrel wear.

🛠️ Professional Overhaul Kit: Contains every technical sealing component required for a full cylinder rebuild, enabling rapid repair without needing additional parts.

⏳ High Heat & Friction Resistance: Manufactured from specialized materials that resist deformation under constant motion and high hydraulic oil temperatures.

🚜 Compatible Models: JCB Backhoe Loader: 3CX, 4CX, 5CX (Rear boom, dipper/arm, and other 100x60 main cylinder applications). We would be pleased to assist you with any inquiries regarding our products. Please feel free to reach out to us at your convenience.
