|
Known Issues
|
Engine Wear:
|
Common for older DT-466 engines to experience cylinder liner wear, piston ring issues, or injector pump problems if not properly maintained.
|
Powershift Transmission:
|
Potential for wear in clutch packs or hydraulic control issues if fluid and filter maintenance is neglected.
|
Electrical System:
|
Wiring harness degradation, starter solenoid failures, and alternator issues can occur with age and exposure.
|
Hydraulics:
|
Leaking hydraulic cylinders, pump wear, or control valve issues can develop over time.
