I have to ask if it's really necessarry to install the cotter pin with a tool in the first place ? - My father taught me fairly early on that using any kind of tool (or hammer for that matter) to seat a cotter pin on the crank meant that it was going to be all the harder and more difficult to remove it the next time. He seemed to an age with engineers marking fluid ("blue") and a fine file, getting a "better" fit on a new cotter pin so it was well seated on the axle, rather than just taking a big hammer to the back of it and making it fit. This was perhaps taking it a little too far but I suppose he had a point, and I don't recall his cranks ever loosening off, and the better fit onto the surface of the axle flat ought to reduce the risk of slippage / movement under load. Other than that you should get it tight enough using the nut supplied.

Best Regards
