Replacement of the hydraulic lift cylinder should not include replacement of the hydraulic motor and pump assembly unless it has been determined the motor and pump assembly is malfunctioning. Investigation of returned field failures of motor and pump assemblies show that the problem is with the hydraulic lift cylinder only and not the motor.
