The existing steering lines can fail on certain 794 AC, 796 AC, and 798 AC Off-Highway Trucks. The hose assembly motion during a left-hand or right-hand turn causes the two hose assemblies from the steering flow amplifier valve to the steering cylinder bulkhead plate to rub against each other resulting in a hydraulic oil leak. |
