mkoch Posted May 18, 2023 Share Posted May 18, 2023 (edited) I stripped a hun on my 1985 BRAT, for the second time! The 36mm castellated nut was at the right torque, with cotter pin. What am I doing wrong? Edited May 18, 2023 by mkoch Quote Link to comment Share on other sites More sharing options...
el_freddo Posted May 19, 2023 Share Posted May 19, 2023 Using the same cone washer? That’ll do it. Replace the cone washer and the concave/convex washer with the replacement hub. Also check the spline on the driveshaft is still good. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
Numbchux Posted May 19, 2023 Share Posted May 19, 2023 The flat washer between the cone washer and the nut, is not flat. It is concave on one side, and convex on the other. Convex side needs to go to the cone washer, if it is backwards, the assembly will not tighten correctly, and the hub will strip. I never had an issue reusing the washers... 1 Quote Link to comment Share on other sites More sharing options...
