Howdy folks! I am tearing down a TRW 500. I have managed to find 2 of 3 pullers I need. The one I have not found yet is the crank puller. I have given up on using the part numbers that are in the manual because they are either outdated or superseded, and I have contacted everyone with a website and no one has this puller. However, I have found that pullers from other bikes have worked for the cam and clutch. The crank gear is approximately 1" in diameter and the puller attaches to external threads. So this puller will have an ID of about 1" and the threads will be internal around 20 tpi. If anyone has a tool thats close to this please reply and let me know the part number and application. Thanx!
