I'm trying to help a friend out who is looking for one of these tools so he can swap out his swing arm on his bike. The tool can be used on various Honda's including the 1100 as I know it.

Does anyone here have one of these they want to part (no PUN intended)with or possibly could loan with a minimal rental and or shippping cost ?

He has one ordered but is back ordered possibly due the disaster in Japan.
Thank you for taking the time to read this post,
Joe

A description is outlined below.

PIVOT LOCK NUT WRENCH
This tool is used to remove, install and properly torque the swing arm pivot bolts on VFRs and certain other modern Hondas, including the NC29. The same tool is also used for the some of the rear engine mounting bolts on VFRs and other Hondas. This is the Honda tool, but specialty tool manufacturers such as KOWA and K&L also make similar tools?not sure if anyone apart from Honda makes ones with the proper offset for the torque wrench, though. As noted in a "Tool Tip" in the Haynes service and repair manuals, the mounting bolt lock nuts can be removed and installed using a fabricated "peg spanner" made from an old 22mm socket, or from 30mm O.D. steel tubing, but the proper torque cannot be applied to the lock nut without the special tool.

PART #07HMA-MR70200

Some additional information he provided me on the tool.

The tool is available only from Honda dealers, under part number 07HMA-MR70200, and lists for $66.50 in the U.S. Oddly, this is not the part number listed in the Honda VFR750F Service Manual (07908-4690002) and which Honda dealers were consistently unable to locate. The offset 1/2" socket drive is located 50mm from the center of the tool, and (supposedly) the torque figures given in the Service Manual have been calculated with the 50mm offset of the tool in mind. The tool's other dimensions are: 32mm O.D. on one end; 40mm O.D. on the other end; and the I.D. is 24mm.

Ahem. That information comes from my Web site, which also has some photos here.

The above information is not entirely correct, btw, as both part numbers are valid (or superceded: 07908-4690003 is the current part number for the pivot lock nut wrench) and they actually refer to two different tools. (In my defence, I may have pulled the earlier part number from an earlier version of the Honda Workshop Manual.) I don't know which US Honda dealers have Honda tools available to order online; most of their systems don't seem to recognise those numbers even though they can be validated on wwwcmsnl.com, for example. (I actually stumbled upon this thread whilst Googling for US Honda tool sources!)

In any case, I have also found these tools in my Japanese Honda Tool Manual, which helpfully provides measurements (apologies for the low-res scans). HTH.

Ciao,

I have one I made from a 1 1/4" socket... it's a crappy job and isn't perfect but I'll send it to ya... it's close enough to get the swingarm pivot ring loose.
 
Thank you all for the replies. I will send your responses to my buddy.
JZH,
Thank you for the clarifications , I copied the information from the message I received from my friend.

Joe, Hang on and let me see if by chance his showed up. I have not spoken to him since last Friday.

tks.... A little math never hurt anyone, esp since the offset from center ( on the tool ) is known

Absolutely. Perhaps I should have been clearer. You can get the lock nut loosened using a home-made notched socket, but the reason for the offset on the special tool is that you are supposed to be holding the inner nut with a hex wrench at the same time you apply a specified torque to the lock nut... :eek::

Ciao,
 
I've heard back from my buddy and his order arrived on Friday. I sent him a link to this post so he could read your comments. Thank you for your feedback and willingness to help out in this situation.
JZH, thanks for posting the photo, I have never seen the tool, quite an interesting looking device.
