I got new cotters, and they are in tight, and the nuts on the threaded end are engaged (one side fully, the other side caught only 2 or 3 threads, but did snug-up). I have 10mm of the non-threaded end visible on each crank. Should I go ahead and sand/file a little off the diagonal face of the pin, to get it to push farther through before I put the nut on? 10mm looks like too much visible.
