MAINSHAFT c/w THIRD AND LOW GEAR
Gearbox mainshaft assembly supplied complete with third and low gear, part number 12276.
This is a mainshaft assembly for the gearbox, listed in the catalog as coming complete with third and low gear already fitted to the shaft. It lives inside the gearbox shell, on the shafts-and-bearings side of the internal cover, and it's one of the two main shafts that carry the gear pinions and dogs which get selected as you shift.

The catalog entry we have on this one is brief, just the single listing tying it to the gearbox shafts, bearings, and inner cover figure. We don't have more detail on this one beyond that.
Because a mainshaft has to mesh correctly with the rest of the gear cluster and the selector mechanism, call the shop and we'll confirm fitment before you order.
