Layshaft 2nd gear (27T)
Layshaft second gear (27 tooth) for the gearbox, also known by its earlier part number T4160.
This is the layshaft second gear, a 27-tooth gear that lives on the layshaft inside the gearbox. It's cataloged under the GEARBOX SHAFTS AND GEARS section, so it's one of the cluster of gears that ride on the layshaft and mesh with the mainshaft gears to give you your ratios as you work the box through the gears.

The older book number for this one is T4160, which shows up on earlier parts lists before the shop switched over to the 57-4160 numbering. If you're working from an old book and see T4160, that's this same gear.
Our catalog record only ties this to one appearance, so we don't have a lot of cross-model history to go on here. If you're rebuilding a box and matching tooth counts, bring in the old gear or your parts book reference so we can confirm you're getting the right one before it goes on the counter.
