Layshaft Low Gear (27T)
27-tooth layshaft low gear for the gearbox, part number 71950.
This is the layshaft low gear from the gearbox, a 27-tooth pinion that rides on the layshaft and gets pressed into service whenever the box is put into first. It's a straightforward piece of hardware but an important one — if it's chipped or worn at the dogs, you'll notice it as trouble finding or holding low gear.

Our catalog record ties this to gearbox shafts, bearings, and inner cover work, so it lives inside the case alongside the other layshaft gears and the bearings that support them. The listing we have only shows one appearance in the books, so we don't have much history on it beyond that single line.
The manufacturer tag on file says Lucas, but Lucas made electrics, not gearbox internals — that tag is off and can be disregarded. Because we're working from a thin record here, give us a call and we'll confirm it lines up with your gearbox before you order.
