GEAR INDICATOR PLATE 500 - BRASS/BLACK
Brass gear indicator plate with black markings for the Triumph 500 unit gearbox inner cover, PN 57-1417 (T1417).
This is the gear indicator plate for the Triumph unit-construction 350/500 gearbox, brass with black markings so you can read your gear position at a glance through the inner cover window. It mounts inside the gearbox where the shafts, bearings, and inner cover come together, and it's a small part but an easy one to lose track of when a box is apart for a rebuild or a clutch job.

The catalog lists it as 57-1417, with the older book number T1417 being the same part under the pre-decimal numbering system Triumph used before the mid-1960s changeover. It's a straightforward swap when the old one is scratched up, faded, or missing outright, and it's the kind of thing worth having on the shelf so you're not waiting on it mid-rebuild.
Our catalog record ties this to the 500 gearbox family and the inner cover assembly, spanning appearances from the late 1960s into the mid-1970s. If you're not sure whether your box uses this exact plate, check it against your own gearbox parts diagram or give us a call before ordering.
