Manitou Group VT320, 3200VT Common Problems This Manual Covers
Loses drive or weak travel
As a hydrostatic track loader, weak travel or one slow track usually traces to a drive motor, base pump, or control valve issue. The hydraulic schematic maps the drive motor, base pump, gear pump, and control valve for diagnosis.
Manual Section: Hydraulic Schematic p. 219Lift or tilt slow or jerky
Slow or jerky lift and tilt often comes from contaminated oil, low fluid, or a restricted filter. The hydraulic system maintenance section covers checking and changing the hydraulic oil and filter.
Manual Section: Hydraulic System Maintenance p. 49Intermittent electrical faults or dead controls
Loose connectors, damaged wiring, or a blown fuse can cause warning lights or dead controls. The electrical schematics cover the chassis, engine, seat, and cab circuits for tracing these faults.
Manual Section: Electrical Schematics p. 293Overheating or high temperature shutdown
Overheating comes from a blocked radiator or hydraulic cooler, low coolant, or a fan or belt problem. The maintenance section covers coolant level, cleaning the radiator fins, and belt service.
Manual Section: Maintenance p. 31Engine derates, hard start, or rough run
A rough running or hard starting engine often means a fuel restriction or water in the fuel. The fuel system maintenance section covers the water separator inspection and changing the water separator and fuel filter.
Manual Section: Fuel System Maintenance p. 46Track and undercarriage wear
Undercarriage wear, loose track tension, and sprocket wear are routine on a compact track loader in abrasive conditions. The maintenance section covers the inspection and service that keep the undercarriage in spec.
