First, the 2.0 differentials hold ~35% more oil compared to the NB48.4 units. Of course this helps with consistency during long mains, but it also extends the time between rebuilds. During our long testing period, we didn’t experience any ‘cooked diffs’ and the oil was exceptionally clean compared to anything else we’ve seen. But oil capacity alone is not responsible for this. |
The second objective was smoothness. After years of improving the performance of our previous differentials, we took that knowledge and put it to work here. We decided on a slightly finer internal gear pitch that meshes better and produces less heat. Less heat results in greater consistency, virtually no fade, and the exceptionally long oil life we observed during testing.
Differentials endure some of the most extreme forces during a run and any diff issue pretty much ensures you’re not going to win the race. With these changes we feel we’ve made them even stronger. During our year of testing, the gears, pins, diff cases, and outdrives certainly stood up to all of the abuse we threw at them.
The larger differentials meant that new bulkheads were required. We used this opportunity to implement some other features we’ve had on our list for a while, such as improving access to the front and rear differentials during maintenance. Let’s face it, if the diffs are hard to access you are less likely to service them or make a setup change. As mentioned above, time between maintenance on the diffs is much longer, but when you need to make that quick setup change before the A-main, you’ll appreciate how quickly and easily they are to access.
