BMW N51/N52/N53/N54 Engine Locking Tool Set – Camshaft TDC Positioning Kit

Brief Overview

This specialized locking tool set is engineered for BMW petrol engine timing work, specifically designed to secure camshafts at Top Dead Centre (TDC) position during critical engine assembly, disassembly, and timing operations. The set covers a comprehensive range of BMW engine generations including N51, N52, N53, N54, and N55 variants across multiple model lines. Whether you're handling routine valve timing work or full engine rebuilds, this tool eliminates the guesswork and reduces the risk of timing errors that can lead to costly engine damage.

For shops working with BMW diesel engines, complementary options like the diesel engine timing locking kit for M47/M57 series and the N47/N47S diesel locking tool set provide complete coverage across BMW's powertrain lineup.

This tool set eliminates those risks and provides the professional confidence needed to complete timing operations efficiently and safely.

Ideal For

• Independent BMW specialists and multi-brand shops
• BMW dealership service departments
• Engine machine shops handling BMW rebuilds
• Fleet maintenance facilities with BMW vehicles
