Troubleshooting Table 20: Hydrostatic Travel Drive System Troubleshooting Problem
Possible Cause Hydraulic oil viscosity too heavy
Drive system noisy
Low hydraulic oil level Air in hydraulic system Drive motor(s) or hydrostatic pump(s) internal damage/leakage Low hydraulic oil level Low hydraulic system charge pressure Drive motor(s) or hydrostatic pump(s) internal damage/leakage
Sluggish acceleration Engine running rough
Drive sensitivity set too low Travel drive does not track straight when left joystick is in the forward or reverse position

Corrective Action Allow longer warm-up Replace hydraulic oil with proper type/ grade. See “Fluids/Lubricants Types and Capacities” on page 33 Top-off hydraulic oil. See “Checking Hydraulic Oil Level” on page 133 Cycle lift and tilt cylinders to maximum stroke and maintain for a few seconds to clear air from the hydraulic system Contact dealer Top-off hydraulic oil. See “Checking Hydraulic Oil Level” on page 133 Contact dealer Contact dealer Poor fuel quality or incorrect fuel type/ grade. Replace fuel with proper type/ grade. See “Fluids/Lubricants Types and Capacities” on page 33 Restricted fuel filter/fuel system. Replace fuel filter; remove restriction.
