Every 6 months I have to retighten the cone screw on the shifter. This time it came out real quick. I thought it might come out all together. I couldn't get 2nd without hitting reverse. The picture shows how much the screw backed out.
Not sure how much torque I applied but I was bending the allen wrench. Questions: Should I have thread locker on this? What is the torque required for the cone screw? Possible that the threads have been widened by repeated looseness? Why didn't they put a bolt through this to really lock the hub onto the shaft?

The cone screw thread appears to be folded over at the bottom. Really messed up.

QUOTE(Spoke @ Dec 6 2024, 06:03 AM)  The cone screw thread appears to be folded over at the bottom. Really messed up. Indeed, also the first of your 2 pix shows a void in the threads where a silicone anti vibration, anti backout slug, would be sitting in a new factory screw. Both of those items likely causing you backing out. |
