Need help with identifying the use of this tool.

It is as blue Park Tool spanner tool number SPA-3. I can not figure out what it is used for. The only thing I can find even mentioning it is this blog but it doesnt offer much explanation and it's a strange tool because the pins point in toward eachother. https://fernandoj.wordpress.com/2013...-do-with-them/

I have the set of early 90's Park pin spanners (4 or 5) and that is one I have never used.

It fits "some" lock rings.
Found with a 10 second search.

It's a solution in search of a problem.

If having it around bothers you, throw it away. Next week you'll figure out what it's for.

Its not a use specific tool, from back in the day when tools were multifunctional. You chose a tool because it did what you needed it to do for that particular task at that particular time. I've got a full set of those Park tools in one of the drawers of my tool cabinet. If I've used it it was because it did what I needed done. Need a suggestion? It'd work great as a temporary tension clamp to hold bar wrap as you stop midway to do something else. Slide it on and the unsecured wrap won't unravel.

LOL!!!
This is a tool I needed for a job once:

But it was expensive, and I needed two of them to get the job done.
So I used some steel rod to make a second tool, but with a simpler design:
https://cimg7.ibsrv.net/gimg/bikefor...532d36f24.jpeg
The job was assembling/disassembling the headset of a Kawasaki 650 Versys.
Only the factory tool is needed to loosen the locknut.
But when reassembling, you need a 2nd tool to just hold the lower locknut while using the factory tool to tighten the upper one.

What a wealth of knowledge, thanks for the help I will try it on "some" lock rings! :P

It's certainly more effort then you seem willing to expend.
I see a trend where you expect us to be "Mr. Answer Man".
Ignore list so I never expend another iota of effort for you.

BTW Another oddity when I was working on that motorcycle:
I have the Park headset tools, and discovered to my delight that the largest components in the headset bearing installation kit, were the correct size to install the bearings on the Kawasaki's triple clamp.

I have actually spent quite some time trying to figure this one out but I guess you wouldn't know that would you. I am curious what your "10 second search" found that made my question so idiotic? I still have not gotten or found any specific information from Park Tool or any legitimate source you included. The best answer you had for me is "some lock rings".

I also like that you say "I see a trend where you expect us to be "Mr. Answer Man". I mean after all isn't bicycle maintenance a hobby and suppose to be fun? Also isnt the purpose of the forum to ask questions and find a "Mr. Answer Man" to things a 10 second search might not find. Nobody is forcing you to use this forum bud or to answer my thread so if you don't have any real knowledge of the subject please keep to yourself and I will gladly accept my spot on your ignore list if I means I don't get your responses.

Used for this type of lockring. I've found this tool to be near useless for tight lockrings on BB's but as Shimagnolo noted in in post #9 it works great for setting the tension on motorcycle headset bearings.

Since you asked so nice. Direct from the pages of Park Tool Catalogue (no date). It is part of a set of Pin Spanners SPA 1-6

SPA-1 Green - Fits adjusting cone on most 3 piece cranks
SPA-2 Red - Fits adjusting cone on most gear clusters
SPA-3 Blue - Fits lock ring on most 3 piece cranks (This is what you show)
SPA-4 Yellow - Fits adjusting cone on most 1 piece cranks
SPA-5 - Set of above
SPA-6 - Shop quality adjustable pin spanner

The one you posted in another thread is half of a Frame and Fork End Alignment Gauge Set FFG-1. I have the other half.

Yeah, for a lockring you really want something that can grip the part, like a pliers:

Tried searching for those with no result.... what would you call them beside lockring pliers

Var 16 Pliers?

There's also the Hozan C-203:

Or, you can make your own from a set of slip-jaw pliers:

I have the FFG-1 tool and have used it but had no idea that part came with it. Thanks for all the help!
