Case IH DX29, DX33, DX33 Tractors Common Problems This Manual Covers
Case IH DX29 engine won't start and starter clicks rapidly when turning the key. p. 76
Inspect the battery electrolyte level and verify it is 6.35 mm (1/4") above the plates as shown on page 76. Test the battery to ensure it meets the 450 amps at -18°C (0°F) cold cranking requirement. Clean the terminals and tighten the starter switch connections.
Manual Section: Lubrication and MaintenanceEngine dies under heavy load or stumbles badly after running completely out of fuel. p. 106
Fill the tank to the 27.6 liters (7.3 U.S. gals.) capacity specified on page 106. Locate the bleeder screw on the injection pump. Open the screw and manually pump the primer until solid fuel flows without air bubbles, then tighten the screw securely.
Manual Section: SpecificationsTractor hesitates when shifting gears or PTO fails to engage smoothly under heavy load. p. 108
Measure the clutch pedal free-travel at the top of the pedal stroke. Adjust the linkage on page 108 until you achieve 19 mm-30 mm (3/4"-1-3/16") of free-travel. Tighten the jam nut securely and test the pedal engagement before operating the PTO.
Manual Section: SpecificationsTemperature warning light flashes continuously on the instrument panel during extended summer field operation. p. 107
Check the warning lights on page 25. Let the engine cool completely. Test the radiator cap to verify it holds exactly 0.9 bar (13 PSI) as specified on page 107. Replace the cap if it fails the pressure test and inspect the coolant level.
Manual Section: SpecificationsPopping noise from the front axle during tight turns on hard pavement or concrete. p. 111
Inspect all wheel hardware for damage or elongation. Torque the front wheel bolts to 122 N⋅m (90 ft. lbs.) using a calibrated torque wrench as detailed on page 111. Check the front axle fluid level and add gear oil if necessary.
