Case IH Maxxum 5120–5150 Common Problems This Manual Covers
Case Maxxum hydraulic warning light on dashboard, tractor losing power or stops moving p. 58
Check the transmission/hydraulic system fluid level immediately. The combined system holds 75 to 80 Litres (16.5 to 17.6 UK gallons) — if low, top up with the correct fluid before running further. Review service indicator lamps on page 58 to confirm which warning is active. Inspect hydraulic lines and connections visually for leaks. If fluid level is correct and the light stays on, shut down and consult your dealer before operating.
Manual Section: Operating InstructionsEngine oil pressure warning lamp stays on after startup, gauge reading low p. 58
Shut the engine down within 30 seconds. Check oil level on the dipstick and top up if below the MIN mark. Normal engine oil pressure at 2200 rpm should read 296 to 372 kPa (43 to 54 psi) — anything below that range at operating temperature is abnormal. Review the service indicator lamps section starting on page 58. If oil level is correct and the lamp persists after a cold restart, do not continue operating.
Manual Section: Operating InstructionsPTO engagement causes unusual noise or vibration, implement not receiving full power p. 110
Disengage PTO immediately. Verify the PTO control is fully engaged and set to the correct speed for your implement. Check that the implement driveline is properly connected and the shield is in place per safety rules on page 15. Confirm engine speed is at the correct operating rpm before engaging. If noise continues after reconnecting, inspect the driveline coupling for damage and check lubrication points per the schedule on page 201.
Manual Section: Field OperationEngine won't start or cranks slowly in cold weather, battery appears weak p. 255
Check battery electrolyte level and terminal connections for corrosion — clean terminals with a wire brush if white or green deposits are present. Battery maintenance procedures are on page 255. Verify the battery is fully charged; a discharged battery in cold conditions will crank too slowly to fire the engine. If the battery tests good, use the cold-start aid per the normal starting procedure on page 58, and confirm fuel system has no air by checking the fuel system section on page 201.
Manual Section: Electrical SystemAir filter restriction indicator lit on dash, engine running rough or losing power p. 222
Stop operating in dusty conditions and service the air filter. Remove and clean or replace the primary element following the procedure on page 222. Do not clean the secondary (safety) element with compressed air — replace it if contaminated. Reinstall the primary element and reset the restriction indicator. Inspect the air intake ducting for cracks or loose clamps that could allow unfiltered air into the engine.
Manual Section: Lubrication/Filters/FluidsRear three-point hitch won't lock in transport position or implement drops unexpectedly p. 243
Check the auto hitch release cable adjustment on page 243. The cable must hold firm tension so the latch engages fully at the transport stop. Verify lift rods are adjusted to the correct length so the hitch reaches the lock point without binding. Test the operator presence switch function to confirm the seat safety system is not interfering with hitch control. If the hitch still drops, inspect the latch mechanism for wear before the next field pass.
Manual Section: Maintenance/AdjustmentsFrequently Asked Questions
How to reset Case IH Maxxum 5120 error codes
To reset the transmission control module and clear fault codes, turn off the engine. This action will cause any stored fault codes to be lost from the module.
How to reset transmission oil pressure light on Case IH 5150
If the CHECK POWER SHIFT INDICATOR lamp illuminates, indicating a fault in the Power Shift transmission, you should put the range lever in neutral, push the clutch pedal fully down, select RANGE, and then slowly release the clutch pedal to start the tractor moving. This procedure is for a fault lamp, not specifically an oil pressure light.
How to reset Case IH 5130 transmission
The transmission control module can be reset by turning off the engine. This action will clear any fault codes from the control module, as it does not have a diagnostic code memory.
How do you fix case Maxxum hydraulic warning light on dashboard, tractor losing power or stops moving?
