Layshaft 2nd gear (26T)
A 26-tooth layshaft second gear for the gearbox internals.
Part number 13861 is a layshaft second gear with 26 teeth, and it lives inside the gearbox on the layshaft cluster where it sits per the parts-book figure covering gearbox shafts and gears. This is a mechanical gear, not an electrical component, even though our records happen to file it under a Lucas-style number - Lucas made electrics, not gearbox internals, so don't let that tag fool you about what this part actually is.

The layshaft carries the intermediate gears that transmit power between the mainshaft and the output, and second gear is one of the fixed or sliding pieces in that stack depending on the box's layout. Our catalog record for this one is thin, tying it only to a single year of appearances, so we can't tell you which specific model it belongs to from what we have on file.
If you're rebuilding a gearbox and matching up gear counts, the 26-tooth spec here is useful for cross-checking against what you pull out of the case. Give the shop a call with your gearbox details and we'll help confirm this is the right one before you order.
