Frequently Asked Questions

What is the difference between a swing motor and a swing gear reducer on a Case excavator?

The swing motor is the hydraulic motor that provides the rotational force, while the swing gear reducer is the gearbox that steps down that output to drive the upper structure around the swing gear. Broken Tractor carries both as separate units, as well as combined swing drive assemblies, for Case excavators. Confirm which component you need before ordering so you match the correct part.
