Chuck Easton on the Triumphs mailing list asked: Has anyone ever removed a broken pinch pin from the clutch fork of a TR6? Well, I just did mine and here’s how to salvage what you have:
- The shaft is toast. You need to cut it off (I used a hacksaw, took about 5 minutes). Make sure you are cutting in a spot which will allow you to withdraw it from the bellhousing once it’s in two pieces (the shaft that is).[Note: Mike Weir, MWeir2@EESUS.JNJ.com , adds the following: I don’t believe it’s necessary to cut the shaft in all cases. They’re not too expensive, but why spend the money if you don’t have to? (one good reason is that the shaft may be significantly worn where it rides in the housing bushes, but that’s another matter). In my case, the taper pin had broken between the threaded shank and the shaft, which is undoubtedly the common condition. I found that by drilling a small hole (1/8 inch) into the other side of the fork from the threaded boss, towards the small end of the pin and on its centerline, the stub of the pin remaining in the shaft could be easily driven out with a pin punch.
