A word of warning

[Chris KC]

I think that's basically a sound approach Andy, but it is generally considered advisable to check kingpin cotters now and then in order to avoid play developing in this frail and critical joint. The distinction which perhaps needs to be drawn is between ensuring they are tight and continually increasing their tightness - which will of course ultimately lead to failure.

20lbft is fine for a 5/16" BSF head nut but a bit much for 1/4" fixings in my humble opinion.
