Bush

A gearbox shaft bush, listed for the T150V five-speed gearbox, also known by its earlier part number T4379.

PN · 57-4379

This is a bush from the gearbox internals, listed in the catalog under GEARBOX SHAFTS AND GEARS, including the T150V five-speed gearbox figure. The older reference for this same part is T4379, which is the letter-prefix form you'll see in earlier parts books.

A bush like this sits on one of the gearbox shafts and gives the mating gear or shaft a bearing surface to run on, taking up wear so metal isn't riding directly on metal. Our catalog record doesn't spell out which shaft or exactly where in the gear cluster it goes, so if you're rebuilding a gearbox and matching parts against your own parts book diagram, check the layout against what you've got in front of you.

The catalog shows this part turning up across appearances from 1972 to 1977, which lines up with the T150V five-speed reference in the figure title. Beyond that we don't have more detail on hand. If you're not sure this is the exact bush your gearbox needs, give us a call and we'll help confirm before you order.
