Castle Nut Wrench for MKV Post to DBox Threaded Collar

[peter keeling]

Im curious if anybody knows of a tool to help tighten and loosen the threaded collar that connects a 1.5" MKV Carbon Fiber post to the D-Box below. I have a dickens of a time ensuring its properly tight with just my hands. A handy tool would surely help, not sure if anybody has come across one that would work.

I would probably use a strap wrench. While I’m sure you could use a castle wrench, a strap wrench will be a bit more universal. Also, if you’re finding that you’re getting play between the D Box and the post, that may be from the edges of the flats on the post connector being rounded over, and I know in the past I helped someone by shimming that with some thin layers of tape to make it more solid.

If you are still getting play then also check you have it on right. Spin the top or bottom section 180 degrees. The older MKV model was directional. If it was wrong there would be tiny bit of play.
