Case Case Tractor Common Problems This Manual Covers
Case Tractor rear brakes locking up or making grinding noises after 100 hours of operation p. 30
Inspect the brake linkages for proper movement and clearance. Measure the brake disc diameter to ensure it meets the 222 mm (8.75 inch) specification found on page 30. Clean the power star brake assembly and verify the pedal free play is set correctly before returning the machine to service.
Manual Section: Diesel Engine SpecificationsPower take-off shaft will not attach to the implement and collar slides forward loosely
Pull back on the spring-loaded PTO release collar instead of pushing it forward. Verify the implement driveline matches the 34.9 mm (1-3/8 inch) output shaft diameter. Clean any packed dirt from the splines and apply a light coat of grease before attempting to connect the shaft.
Manual Section: General SpecificationsEngine will not turn over or start when turning the ignition key in the operator cab p. 29
Verify the PTO lever is fully disengaged and the transmission is in neutral. Check the dipstick to ensure the crankcase is filled to the 12.5 litres (13 U.S. quarts) capacity shown on page 29. Inspect the neutral start switch for corrosion or a damaged switch ball.
Manual Section: Diesel Engine SpecificationsEngine overheating and coolant temperature gauge reading high during heavy field operations p. 28
Check the coolant level in the radiator recovery tank before starting a cold engine. Drain and flush the cooling system, refilling it to the 15.3 litres (16 U.S. quarts) capacity detailed on page 28. Inspect the radiator fins for blockages and clear any packed dirt.
Manual Section: Diesel Engine SpecificationsFrequently Asked Questions
