Unusual Suntour bottom bracket

I just obtained a Suntour bottom bracket that is a sealed unit which can be adjusted for chain line. The end "cups" have eight square notches with a diameter just under the thread diameter. The lock rings are separate from the cups. The chain line is adjusted by adjusting both cups to the left or right, then tightening the lockrings to secure them. I haven't been able to find any mention of this bracket anywhere on-line, and will probably have to make my own tool to adjust the cups. Has anyone else seen these before, or know where a tool to fit the cup patern may be obtained ??? I have the original box but there is no part number on the box or part itself. The lock ring is inscribed Suntour-II Photo attached

I've got a tool (think I got it in the '80s) but have no idea where you'd be able to buy one.

Says Suntour Japan in the middle of one side, no other markings, stamped tool. Has three folded tags at 90 degrees each at one end to fit the bearing retainers and two slightly smaller similar tags at 180 degrees at the other to fit the lockrings. Not set up for photos...

Tange did a similar BB (probably made the Suntour) but their tool is slightly different.

I'm pretty sure that is the same BB that came on my '86 Cannondale SM 700. The rest of the grouppo was XC Pro. The rollercam brakes wheels were mounted BETWEEN flanges on the brake arms (as opposed to the outside of the brake arms; XC model) I think Phil Wood BB tools have 18 notches.
My C'dale still has the original BB and it is as smooth as the day it was new. Nice find!

Oops, I'm wrong about the Phil tool!
BUT, I do happen to have 2 of the correct Suntour tools in my box, in case you want to "borrow" one.

Ah, just checked and you MAY be able to use a Park PA-SPA4 Adjustable spanner. The one with YELLOW handle. Your LBS may have, or can get you one of THOSE!

That's the BB that came on my Fuji Touring Series V. If you decide it's excess to your needs, let me know.

My '83 Specialized Expedition came with one of these BBs too. Advice was to leave it alone as it will likely outlast the frame. Doesn't help you much if you are trying to install/remove one.

Yes! I destroyed mine because (a) I had no idea what I was doing and (b) I wouldn't have had the tool if I had known. I think I still have all the parts in a bag as a memorium to my shame.

Is it possible for the square taper spindle of the bottom bracket to become loose? I think I either have 1 mm play in my bb

O gawd. I ran into one of those last year and it almost killed me getting it out. I finally used an adjustable pin spanner with the pins filed for a better fit. It needed to come out, too, as it was proper ****ed. Really cool unit but rust never sleeps.
