This is a tool used to prevent the flywheel from spinning during clutch replacement. I designed the part for a 06 BMW 325i with a N52 engine and Getrag 6 speed clutch. I think it will work with most BMW's as they use the same spline count on the flywheel.
The tool is designed to sit over the dowel at the 6-o-clock position and use one of the old aluminum bolts (or any similar object) to hold the tool in place while the filwheel bolts are being torqued.
Included a 0.15" spacer that I ended up not using. This was for any issues with the dowel.
