39/40T RingGear, spare gear set for XV-02 TT-02

This spare gear set brings the key drivetrain parts for direct coupling service into one focused pack. The set contains 2 direct coupling ring gears, one with 39 teeth and one with 40 teeth, plus 2 bevel pinion gears matched to those tooth counts. That layout gives a clear replacement route when the front direct coupling assembly needs the specified parts for continued use. The parts are named for Item 22047, the XV-02/TT-02 Front Direct Coupling Set with 39T, which places this set squarely in the drivetrain area rather than as a general hardware assortment. The 39T ring gear works with its dedicated bevel pinion gear, and the 40T ring gear works with its own matching pinion, so each pairing stays tied to the correct tooth count. The image-supported layout also makes the difference between the 2 ring gear options easy to identify during bench work, with each larger ring gear shown alongside its smaller mating pinion. Compatibility is stated for XV-02 and TT-02 chassis cars, making the set a practical choice for maintenance, repair, or keeping the correct replacement gears on hand between running sessions. On a workbench, the paired parts support straightforward selection when servicing the front direct coupling area of those chassis platforms.
