I've been digging around and I can't find where anyone (or business) has identified the different drum diameters for the 6 and 3 shoe 925 clutches. My 925, with the mystery clutch, has a drum measuring 3.1" ID. Does anybody know if it belongs to the 3 or 6 shoe clutch?
Thanks, Chris B.
By my measurement, the drum is 2.996" inside diameter. Oregon 37458X B is the rim drive drum you are looking for, for the three shoe clutch. Scored one a few weeks ago.
3.100" would be a bit overbig for a 3 shoe I think.
