I think its a 35mm socket but I used a 36mm since my set goes from 34 to 36 and it worked fine.

Remove the wheel, brake and fender, and remove the forks from the trees. Place the bottom of the fork tube on the ground (on a towel for protection) and press (by hand) the nuts back on. Turn left 'til you hear the threads click, then right to get them started.
Hope this helps.

What I did
Did it by hand, working on my Nightster replacing the OEM front fork springs with Progressives. The trick I think was to thread the cap in a bit with out the spacer, then slowly unthread the cap with slight outward pressure to "mark" the exact spot in the rotation that the threads meet. Keeping the cap in rotational position, slip the spacer in, then with both hands push down on the cap until you feel it bottom out. Now rotate it clockwise as best you can while maintaining the pressure to keep it bottomed out. It is a bit tricky, it took me 3-4 tries on each side to get the threading started. Once you've got the threading started by hand, apply your wrench/socket easily, making sure your threads are aligned correctly, and not just caught. I suppose if the pre-load tension for a Street Bob/Dyna is greater than the Nightster's, then this manual process might be problematic. I guess it also depends on your hand strength/dexterity.

its actually a 35mm but a 36 will probably work. They're much more common. I had to special order the 35.

Open the top, and bottom of the tubes on the bike, and drain the oil.
Remove the wheel, brake and fender, and remove the forks from the trees. Place the bottom of the fork tube on the ground (on a towel for protection) and press (by hand) the nuts back on. Turn left 'til you hear the threads click, then right to get them started.

If you have a mm ruler you can measure it yourself. If you don't have one:
35 mm equals 1 3/8 inch...
Once you've found out, please let me know and I will add that info to my ***dyna models metric sizes database***
