PROBLEM

Show/hide table

The existing hydraulic tank is too shallow on certain 301.6C and 301.8C Mini Hydraulic Excavators. If the existing hydraulic tank allows the strainer to become exposed to air, it can cause cavitation resulting in noise and potential damage to the pump. This can happen when the machine is working on steep side slopes.
For the purpose of this service letter, a failure is defined as excessive aeration of the hydraulic oil and associated pump noise when the machine is working on steep side slopes.
