GEAR,EARLY 5 SPEED L/S 2ND
Layshaft second gear for the early five-speed gearbox conversion, part 57-4388 (T4388).
This is the layshaft second gear from the early five-speed gearbox setup, part number 57-4388, also known by its legacy code T4388. It shows up in the gearbox shafts and gears figures for the T150V five-speed box and in the parts list covering the optional five-speed gearbox conversion, so it's tied to that early five-speed layout rather than the standard four-speed unit.

As a layshaft gear, it sits on the layshaft inside the gearbox and meshes with its mating gear on the mainshaft to give you second gear. If you're rebuilding an early five-speed box and find chipped teeth, excess play, or noise isolated to second gear, this is the gear to look at.
Our catalog record only places this across a couple of entries from the early 1970s five-speed conversion parts, so if you're not certain your gearbox is the early five-speed type, check the casing and internals against your parts book before ordering.
