PROBLEM
Show/hide table
| The existing 45 degree elbow adapter may loosen on certain 312E Excavators. The existing hose routing for the blade lines can expose the 45 degree elbow adapter to loosening, generated by inertia load of upper frame rotation, when the right swing operation is stopped. If the 45 degree elbow adapter becomes loose, it can result in hydraulic oil leakage or connector breakage. |
