Hi Sydney or anyone else who is interested,
I received the 113 mm spindle for the Sugino 46/36/26 chain ring last week and finally got around to assembling it today. The 113 spindle does not work on my bike because the adjustment cup has wrenching protrusions on the outside surface which interferes with the left crank by a millimeter or so.
The 117.5 mm spindle will not have the left crank interference but the chainring will be outboard by 1 1/2 mm more than with the shorter spindle. The chainline with either the 113 or 117.5 spindle is much improved over the original setup. The left crank will also be outboard more with the 117.5 but this is inconsequential, I think. The left crank was outboard a bunch with the original setup.
I was pleasantly suprised to find the BB area on this old bike is clean.. no rust. The caged balls and the original bearing surfaces on the old spindle are in excellent condition and the lube was relatively clean. It looks like bike was not used very hard and stored out of the weather.
It looks by eyeballing the chainline, that the old Shimano 200 SX FD will index with the 113 spindle and should index with the 117.5 if it is outboard by only 1 1/2 mm (.060 inches) more.
I will check out one of my favorite used bike shop to see if I can find an adustment cup with no protrusions that uses a pinned spanner tool. If I am lucky to find a cup, I will also have to find a used tool or make or buy a new one. If not, I will have to exchange the 113 for a 117.5. Could not find such a cup on the WWW.
After all this messing around, I could have probably used a sealed cartridge from the LBJ at the same cost,
but I prefer to preserve the original ball and cup setup just to be different.
Would appreciate any comments.
