Case 435, 445CT, 445 Common Problems This Manual Covers
Case 435, 445CT, 445 controls lock up when safety locks actuate and throw code E01. p. 729
Test the parking brake release mechanism circuit. Verify the parking brake release pressure reaches 1500 kPa (15.0 bar) (218 psi) as shown on page 729. Inspect the safety lock interlock switch for binding and replace the release button if the fault persists.
Manual Section: Parking Brake HydraulicHydraulic oil leaking near rear fittings with hidden electrical harness faults and intermittent E12 codes. p. 13
Inspect the number 10 JIC 90 fittings for cracks. Torque the 37-degree flare fittings to 77 to 85 Nm (684 to 756 lb/in) following the specifications on page 13. Clean the wiring harness connector in the concealed electrical section to clear the fault.
Manual Section: Distribution SystemsHydrostatic transmission exhibits low power in forward and reverse when operating under heavy load conditions. p. 509
Measure the hydrostatic transmission pump system relief pressure. Verify it reaches 34,500 kPa (5003 psi) for the 445 and 445CT models as detailed on page 509. If pressure is low, inspect the charge circuit and replace damaged pump drive components.
Manual Section: Transmission HydrostaticEngine overheats quickly during operation and coolant temperature sensor reads erratically on the instrument cluster. p. 429
Drain the cooling system and inspect for blockages. Fill the system to the full 17 L (18 US qt) capacity as specified on page 429. Test the coolant temperature sensor circuit for opens or shorts and verify the radiator fins are clear of debris.
Manual Section: Engine Coolant SystemFrequently Asked Questions
How to exit service mode on a CASE 435?
To exit the Setup Menu (which functions as a service mode), you can either leave the loader for three seconds until the EIC automatically powers down, place the ignition key in either the ACC or the ON position, or push and release the auxiliary override button. This procedure is outlined in the 'EIC Special Functions (Setup Menu)' section.
What are the replacement specifications for Hydraulic fitting number 10 JIC 90?
For a Hydraulic fitting with a Nom. SAE Dash Size of -10, which corresponds to a 7/8 - 14 thread size, the torque specifications are 77 to 85 Newton metres (684 to 756 lb/in or 57 to 63 lb/ft). These values apply to 37 Degree Flare Fittings.
How do you fix case 435, 445CT, 445 controls lock up when safety locks actuate and throw code E01?
Test the parking brake release mechanism circuit. Verify the parking brake release pressure reaches 1500 kPa (15.0 bar) (218 psi) as shown on page 729. Inspect the safety lock interlock switch for binding and replace the release button if the fault persists.
How do you fix hydraulic oil leaking near rear fittings with hidden electrical harness faults and intermittent E12 codes?
Inspect the number 10 JIC 90 fittings for cracks. Torque the 37-degree flare fittings to 77 to 85 Nm (684 to 756 lb/in) following the specifications on page 13. Clean the wiring harness connector in the concealed electrical section to clear the fault.
