High gear bush
A gearbox high gear bush, letting the high gear turn freely on its shaft inside the gearbox.
The 57-4006 is a high gear bush out of the gearbox internals, listed in the catalog under the GEARBOX SHAFTS AND GEARS figure. It's the bush that the high gear rides on inside the box, letting that gear turn smoothly on its shaft without wearing the shaft itself.

This part shows up in our records under the older T4006 number as well, so if you're working from an early parts book that's the same physical piece. Our catalog entry for it is thin - only the one listing, tied to 1971 - so beyond knowing it's a gearbox bush for the high gear, we don't have more detail on hand.
If you're rebuilding a gearbox and need to confirm this is the right bush for your box, give us a call and we'll go over fitment before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
