Diesel High-Pressure Fuel Pump Remover & Sprocket Retainer – BMW N47 / N57, Mini & Toyota – AST Tools AST5014

Specialist service tool designed to extract the high-pressure diesel injection pump while securely retaining the drive sprocket and timing chain in-situ on BMW, Mini, and Toyota 1.6, 2.0, and 3.0 diesel engines (N47, N57, 1WW, 2WW). Significantly reduces required engine teardown time.

The AST Tools AST5014 high-pressure pump extractor and sprocket retainer is an essential piece of workshop equipment when servicing BMW N47 and N57 common rail diesel engines.

Because the timing chain assembly on these engines is mounted at the rear of the engine block, conventional pump removal would otherwise necessitate extensive dismantling. The AST5014 threads directly into the high-pressure pump drive sprocket, firmly securing the sprocket and timing chain against the inner timing case. The central forcing screw then pushes the tapered pump drive shaft clear without altering valve or pump timing.

This clever dual-function design allows the injection pump to be removed for bench testing, resealing, or replacement with minimal engine disassembly, saving hours of labour.
