Case IH 235 Common Problems This Manual Covers
Engine runs hot and coolant boils over the radiator cap during heavy mechanical front drive operation.
Inspect the fan belt tension and check the grille screens for debris. Verify the pressure cap holds exactly 12.8 PSI (88.2 kPa) before replacing it. Flush the system and refill with 6.34 U.S. Quarts (6 Litres) of fresh coolant solution as shown on page 130.
Manual Section: Cooling System p. 130Frequently Asked Questions
How to reset oil pressure warning Case 235?
The manual does not describe a specific reset procedure for the oil pressure warning. If the engine oil pressure indicator comes on, you should shut off the engine immediately and check for the cause. If the indicator stays on after starting the engine, stop the engine and investigate the problem. p. 23
How do you fix case 235 tractor hydro diesel engine fails to engage or start due to bad ground connection?
Inspect the battery cables and terminals on page 156. Clean the negative cable and verify a tight ground connection to the chassis. Check the fuel level and fill the tank with up to 4.75 U.S. Gallons (18 Litres) of diesel before attempting the normal starting procedure. p. 156
How do you fix range lever gets stuck and switching from neutral to low or high range is extremely difficult?
Check the neutral start switch and range shift lever adjustments on page 146. Clean the switch terminals and adjust the lock nut to ensure proper linkage travel. Test the tractor operation under load up to the maximum 18HP at 2700 RPM to confirm the transmission shifts smoothly. p. 146
How do you fix roll over protective structure rattles loosely during operation or hinge components show excessive vibration?
Inspect the foldable ROPS frame and hinge components on page 159. Verify the seat belt mounting bolts are tight. Torque all ROPS mounting bolts to 33 to 40 LB FT (44 to 54 Nm) and secure the frame in the upright position before operating the tractor. p. 159
