Return spring housing
Return spring housing for the gearbox outer cover, also numbered T1871 in older parts books.
The 57-1871 is a return spring housing that lives in the gearbox outer cover, on the lever side where the gear change mechanism does its work. This part shows up in the parts books under the GEARBOX OUTER COVER AND LEVERS figure, and it also carries the older T1871 number for anyone working from a pre-decimal parts list.

Inside the housing sits the spring that returns the change lever (or the related actuating lever) to its rest position after each shift. It's a small but important piece of the shift mechanism's feel — without it working right, the lever won't snap back the way it should. Our catalog record shows this part appearing across a run of years from the mid-60s into the mid-70s, so if you're sourcing one, check it against your own gearbox cover before ordering.
If you're rebuilding an outer cover assembly or chasing a shift lever that isn't returning properly, this housing is worth checking along with the spring itself and the lever it works with.
