PROBLEM
Show/hide table
| The 308-0788 Pressure Switch for the secondary steering can be damaged by rapid pressure fluctuations on certain IT62H Integrated Toolcarriers, 950H, 962H, 966H, and 972H Wheel Loaders. If the switch fails it can result in the switch remaining in a high pressure state with zero applied pressure. |
