Breaking-in method for mechanical multi-disc clutch type LSD limited slip differential gears

Break-in break-in for mechanical limited-slip differentials

Breaking-in operation is expected to prevent initial failure, stabilize performance, and extend service life.
The reason why break-in is necessary is that when the differential is new, there are errors in design tolerances and machining marks, and if a high load is suddenly applied, the differential may not perform as designed due to excessive wear.
The lubricating oil will become absorbed in the parts, and the parts will slide and rub against each other, and the designed operation will gradually be achieved.
This is not limited to LSDs, but is especially important for LSDs and some engines.
(An LSD is a differential, a device that creates a rotational difference between the right tire and the left tire.
Therefore, if there is a wide place where cars can run, we drive for 30 minutes in a figure 8 while turning the steering wheel deeply to the left and right. (Last year, I did a break-in run for the LSD, but at that time, I did figure-8 for 30 minutes in a parking lot of a dam lake after driving 1000 km in town or driving on a mountain pass.)

I think either order is fine, but I think it is better to drive on the street first, as it is lighter load.

If there is no place to do so, it would be better to ride 1000 to 2000 km in town, or if there is a mountain pass or winding road nearby, it would be better to drive at a speed where the load is not too heavy and the steering wheel is turned as deeply as possible.

For breaking-in, Temperament Lube ZnDTP should be added up to the maximum concentration to achieve the ideal hit.

Continued use of ZnDTP after break-in will prevent wear, improve LSD effectiveness, and maintain performance and longevity.
