Used for securing the crankshaft with the transmission installed(connected to engine). Use on BMW N20 and N26 engines. While replacing the timing chain, this tool can hold the flywheel. It helps to release and tighten down the central bolts on the vibration damper. Note: Automatic transmissions only. Comparable to BMW Factory Tool No. 83302222742.
When I tried this automotive tool, it didn't work as expected. The design of the tool was not suitable for holding the flywheel in place, and it kept slipping. The price of this product is too high for its inefficiency.
This flywheel holder has worked very well to replace the timing chain in my N20 engine. I still had to secure the back of the tool with zip ties. But that's not a big problem. This allows the tool to enter the groove and the teeth will match the flywheel in the gearbox.
Pros
