Hello

Looking for some help to id a part on my 70's ross eurotour 3-speed IHG. I was repairing a flat when I tweaked it. Looked all over and just can't seem to identify it.

I think its a tensioner?
Any help with trying to id and get a replacement part is greatly appreciated.

from what I can see of the pic it is indeed an adjuster for the internal gears.As you pull on the cable it rocks on a pin that inters the hub and changes the sun gears inside the hub. it doesnt seeem to be broken or bent,so why replace it?

Accuracy helps - I assume by "tweak" you mean you broke it. If you merely bent the arm you can usually carefully bend it back straight.

That is a Shimano 3 speed bell crank.

If you look in the little window there (may need to clean a bit) you will see a red "N." That stands for Neutral as far as I know, but of course there is not neutral in a 3 speed. Rather that is where you set the cable tension on the three speed. There should be a thin locknut below it. You screw down the bell crank until you feel it bottom out on the axle and then tighten the locknut against it. If needed loosen the axle nuts and rotate the axle as needed so that the bell crank points at the cable. Tighten the axle nuts with correct chain tension. Finally, set the shift lever in 2nd gear (may say N) and use the cable adjuster so that the N is centered in the window. There is also a red line that should be centered in the slot that extends from the window.

To find a replacement check locally or use Google. For any other info Google Shimano 333 3 speed.

As you point out, there is no neutral in IGH gearing. The N stands for Normal, as in low, normal, and high.

Makes perfect sense, and I knew that somewhere in my head, but too early in the a.m. Thanks, FB

Thanks everyone. I tweaked the arm of the adjuster. The picture above was just what I could find on the internet. The arm on the bolted end is twisted from getting caught on the bike after loosening the bolt for the rear tire.
