PROBLEM

Show/hide table

The existing swing motor can cause swing hesitation on certain 312D, 312D2, 312E, and 313D Excavators. If the existing swing motor leaks the system oil through the bushing to the case drain it can cause swing hesitation. The swing motor might not rotate in cold temperature. During operation, the swing may feel as if the swing brake is applied.
