Question

1- sprocket hub 6P9107
9- sprocket segment (3 tooth) 9T6782
1- adapter ring 9S6678
1- rim 1S8725
27- bolt 9S2727
serial # 46A2234-2787,46A12585-17168 use 3S7837 bolt
27 nut 7H3609

For what serial number...I show two for the 46A24433 to last built.
8S3018 and a 6P9107.
The 6P9107 is also shown as part of a 6P9108 sprocket segment group - field installation- for use with the new 8 degree dual cone seal.

Here is my dilemma:

I have been trying, with no success, to find "new" weld on rings or sprockets for my 13A. I have a beautiful set of rails but my sprockets are marginal. The used parts guy at Holt told me the 46A segmented hub will fit on my 13A and convert it to the later style rails. I need the part number to check with other sources to locate them. I have already ordered that dual cone seal conversion group for the old style sprocket you told me about, but I can send it back if needed.

Is this the right direction? I am open to suggestions

The number I have for the plain sprocket 8.0 in pitch weld on rim is a 9B2897 but that probably has been superseded.

There are three choices of weld on adapters for segmented sprockets. Don't know if you have all the numbers or not so here is the list.

For the old 8.00 in pitch (non-current)
Adapter ring 4S9077
Segment 4S9112
These are 14 tooth with a 35.87 in pitch diameter
and 7 segment.

For the 9.00 in pitch (current)
Adapter ring 9S6678
Segment 6T6782
These are 27 tooth with a 39.02 in pitch diameter
and 9 segment


For the 9.00 in pitch (upgrade)
Adapter ring 5S0121
Segment 5S0122
These are 25 tooth with a 36.19 in pitch diameter
and 5 segment.

As far as sprocket hubs there may be an interchange with the 46a but there is a Heinz variety of part numbers that would have to be sorted through to
be sure to get the right ones. I have all the manuals but I can't tell you the interchange.
