Diesel Fuel Pump Remover & Sprocket Retainer (Transverse Engines) – AST Tools AST4554

Specialist service tool designed to extract high-pressure diesel injection pumps while retaining the pump drive sprocket and timing chain securely in position. Low-profile design specifically engineered for transversely mounted engines and tight engine bays.

The AST Tools AST4554 pump remover and sprocket retainer is an indispensable workshop tool for servicing BMW common rail diesel injection systems. It allows the diesel high-pressure pump to be pressed off its tapered drive shaft without disturbing the timing chain assembly.

The tool screws into the sprocket aperture, holding the sprocket and timing chain firmly against the inner timing case. The forcing screw then pushes the pump shaft free. Its compact, low-profile body is essential for front-wheel drive transverse applications (such as the Rover 75 and Land Rover Freelander Td4) or rear-wheel drive bays with tight bulkhead and inner wing clearance, where standard-length pullers cannot fit.

Key Features & Benefits

• Timing Chain Security: Retains the drive sprocket and timing chain in place, eliminating the risk of losing engine timing when removing the fuel pump.
• Low-Profile Compact Body: Specially sized to fit tight engine compartments and transverse configurations with limited clearance to the inner chassis leg.
• Saves Workshop Time: Eliminates the need to strip front timing covers, cutting repair times significantly.
• Precision British Engineering: Manufactured from high-tensile steel with precision-cut threads and durable chemical blacking.
• Trade Quality: Built by AST Tools UK to withstand rigorous, repeated garage use.
