Mainshaft third gear (24T)
A 24-tooth mainshaft third gear from the gearbox internals.
This is a mainshaft third gear, 24 teeth, out of the gearbox internals. It rides on the mainshaft inside the gearbox shell, one of the pair of gears that engages to give third when you're working the pedal or lever. The manufacturer tag on this one says Lucas, but Lucas made electrics, not gearbox internals, so don't put much weight on that part of the record.

Our catalog record for this one is thin, just the single listing tying it to the gearbox shafts and gears figure for 1969. Worth handling like any gear cluster part: check the dogs and bore for wear before you put it back in service, and compare it against what's already in the box before you order.
Give the shop a call if you want us to confirm this matches what's in your gearbox before you commit to it.
