Kubota KX080-3 Common Problems This Manual Covers
Hydraulics overheat or lose digging power
Low or contaminated hydraulic oil and clogged cooling screens cause overheating and slow, weak operation. The troubleshooting section covers hydraulic system issues.
Manual Section: Troubleshooting p. 44Engine overheating warning
Low coolant or a radiator packed with debris drives the coolant temperature up under load. The troubleshooting section covers overheating diagnosis.
Manual Section: Troubleshooting p. 70Track derails or wears unevenly
Incorrect track tension, worn rollers and sprockets, or mud packed in the undercarriage pull the machine to one side. The adjustments and replacements section covers track tensioning.
Manual Section: Other Adjustments and Replacements p. 70Squeaks and rapid pin and bushing wear
Skipped daily greasing of the boom, arm, bucket, and swing joints leads to squeaks and accelerated wear. The maintenance section sets the greasing schedule and intervals.
Manual Section: Maintenance p. 70Rough running from water in the fuel
Water or debris in the tank and a neglected water separator cause fuel starvation and rough running. The adjustments and replacements section covers fuel system purging.
Manual Section: Other Adjustments and Replacements p. 100Wrong hydraulic oil level reading
Checking the sight glass with the boom or blade in the wrong position makes the tank look low or overfilled. The maintenance section gives the correct check position.
