BMW Crankshaft Rear Oil Seal Removal/Installation Kit for N51, N52, N54, N55 Engines

Brief Overview

This specialized crankshaft rear oil seal kit is engineered for clean, damage-free removal and installation of rear crankshaft seals on BMW N51, N52, N54, and N55 petrol engines. The kit includes precision-machined aluminum and steel components designed to distribute sealing pressure evenly and prevent seal lip distortion—a critical requirement for preventing oil leaks and ensuring engine longevity. If your shop services BMW powerplants regularly, this tool pays for itself within a few jobs. For shops working with broader drivetrain maintenance, consider complementary tools such as oil seal installation systems for rear axles to expand your service capabilities.

Key Features

• Orange Anodized Aluminum Seal Cup: Engineered to guide the oil seal straight onto the crankshaft without edge contact or tilting. The precision bore ensures repeatable positioning across multiple installations.

• Mounting Block Adapter: Heavy-duty rectangular black steel block with threaded studs and through-holes for secure clamping to engine block or crankshaft holder. Prevents tool shift during installation pressure.
• Complete Fastener Set: Includes bolts, washers, and nuts for secure assembly and mounting to existing workshop equipment.
• Protective Carrying Case: Blue plastic case with foam inserts keeps components organized, protected from damage, and ready for transport between job sites.
• Instruction Card: Yellow reference guide included in case lid for quick procedure reference.
