Case IH MXU100–MXU135 (Maxxum) Common Problems This Manual Covers
Case IH Maxxum warning light illuminates on the instrument console during field operation
Check the error code and record the fault number before clearing it. Verify engine oil, coolant, and hydraulic oil levels are within the MIN/MAX range on their respective dipsticks and sight glass. If the light returns after startup, let the engine cool at 650 rev/min for two minutes, then review page 334.
Manual Section: Controls, Instruments and OperationTractor stalls or loses power when working in heavy or wet soil conditions p. 334
Check the fuel level; MXU100 and MXU110 tanks hold 177 litres, while MXU115, MXU125, and MXU135 tanks hold 220 litres. Inspect the in-cab fuel pre-filter bowl for water separation or sediment buildup. Verify the air intake restriction warning is not active on the instrument panel, then work through the engine fault list on page 334.
Manual Section: Engine TroubleshootingExcessive black smoke from exhaust during hard acceleration, engine feels flat and unresponsive p. 334
Inspect the air intake restriction indicator on the instrument panel first; a red-zone reading means the outer filter element needs replacement. The maintenance schedule on page 273 sets that interval at every 600 hours. Also confirm engine speed reaches rated 2200 rev/min under load. If smoke continues with a clean air system, review engine troubleshooting on page 334.
Manual Section: Engine TroubleshootingHydraulic system loses pressure gradually after two or three hours of continuous operation p. 340
Check the hydraulic oil level in the sight glass at every 10-hour daily service interval (page 267). If the level is correct and the oil temperature warning activates on the console, stop work immediately and let the system cool before continuing. Then review the hydraulics troubleshooting chart on page 340 to identify whether a control valve or circuit fault is present.
Manual Section: Hydraulics TroubleshootingEngine coolant temperature gauge rises rapidly during extended fieldwork, warning light illuminates p. 334
Stop field work and let the engine idle at 650 rev/min for two minutes before shutdown. Check coolant level in the expansion tank only when the engine is completely cold. The radiator cap is rated at 1.0 bar (page 364) and must never be opened on a hot engine. Work through the overheating checklist starting on page 334.
Manual Section: Engine TroubleshootingAir intake restriction warning active on dashboard, engine sluggish and down on power p. 273
Inspect the air cleaner service indicator in the cab and compare its reading against the red service zone. Replace the outer air filter element every 600 hours per the maintenance chart on page 273, or sooner if the warning activates mid-shift. Empty the pre-cleaner dust bowl if your machine is fitted with one. Never tap or blow out a paper element with compressed air.
