Mainshaft distance piece
Mainshaft distance piece (spacer) for the gearbox, positions the mainshaft against its bearings and inner cover.
This is the mainshaft distance piece, a spacer that lives inside the gearbox on the mainshaft, positioning things correctly relative to the bearings and inner cover. The old book number for this one was T1411, before the shop moved to the modern 57-1411 numbering.

It shows up in the parts books under the GEARBOX SHAFTS, BEARINGS AND INNER COVER figure, which tells you it's doing its job down where the mainshaft rides through its bearings and up against the inner cover. Not a glamorous part, but if it's missing, worn, or the wrong thickness for the stack you're building, you can end up with excess end float or a mainshaft that isn't sitting where it should.
Our catalog record on this one spans a run of years without pinning it to one specific model, so if you're rebuilding a gearbox, check what you pull off the shaft against this before you order a replacement.
