    Page 18 of my 2010 PT425 parts manual is attached below. The nut may be item 7: 1 1/4-12 half locknut. Hope this helps.

    Still tight.

    Remember, wrench size and bolt sizes are different. Quick google shows that the standard wrench size for a 1-1/4" bolt is 1-7/8". But 1-13/16" fits mine quite well.

    If you don't have one of these -vernier1-gif, you can use the crescent wrench to find the size. Put it tightly on the nut, then measure the opening with a ruler..

    Default Re: correct wrench

    I seem to recall the formula for wrench size is to take the bolt diameter + add half the diameter to it to get the wrench size. Add an additional 1/8" for heavy hex nuts. So a 1" bolt would be 1" +1/2"=1 1/2" for wrench size on a standard nut or 1 5/8" if it is a heavy hex nut.
