PROBLEM

Show/hide table

The hydraulic drive motor groups, part numbers 358-5003, 358-5005, and 358-5007, have experienced reduced performance of the hydrostatic drive system due to premature wear between the piston block and the distribution valve on certain 246D and 262D Skid Steer Loaders. Initial symptoms include stoppage or failure to rotate the any of wheels during a low idle rabbit mode counter rotation command. This typically occurs when the hydraulic oil temperature is steady around 80 degrees Farenheit. Another early indicator of these failures has been high minimum calibration current during the factory calibration process. These affected machines were identified as high probability of drive motor failures. Proceed with the Rework Procedure in order to prevent any resultant damages to the rest of the hydrostatic system.
