Original BMW S54 Valve Shim Installation Tool for BMW M3, Z3 M, and Z4 M (2001–2008)

The Original BMW valve shim tool, BMW tool number 114 400, is a magnetic tool for removing and installing the valve adjustment shims on the S54 engine in the BMW M3 (2001–2006), Z3 M Coupe and M Roadster (2001–2002), and Z4 M Coupe and M Roadster (2006–2008). The S54 uses solid lifters instead of hydraulic lifters, which is unusual for a modern engine, so its valve lash has to be set by hand. During a valve adjustment each shim is removed and measured. It then goes back in, or a different shim replaces it, depending on whether the clearance is within specification. BMW designed this tool specifically to make that job simpler. It is a genuine BMW tool made in Germany.

Original BMW Parts carry a 24-month parts warranty.

On an engine that sets clearance with shims, each shim has to be removed, measured and either reinstalled or replaced. This magnetic tool is used to remove and install the valve adjustment shims. This tool carries two identifiers. The parts number is 83-30-0-493-743, and BMW's tool number is 114 400. Both refer to the same piece. It is a dedicated S54 service tool and is sold individually as a single tool.

Common Questions

Will this tool work on a hydraulic-lifter BMW engine?
BMW built it for valve adjustment on the solid-lifter S54. Hydraulic-lifter engines do not use adjustment shims, so they have no need for it.

Is part 83-30-0-493-743 the same as BMW tool 114 400?
Yes. 114 400 is BMW's workshop tool number for this magnetic shim tool, and 83-30-0-493-743 is the number used to order it.
