Case IH DX25, DX29, DX33 Common Problems This Manual Covers
Case IH DX25 hydrostat transmission leaking fluid from the rear axle housing and losing forward drive power p. 56
Inspect the transmission housing for visible leaks. Drain the fluid and refill the H.S.T. transmission to the proper capacity of 7.5 gal. (28.4 L) as noted on page 56. Check the dipstick to ensure the fluid level rests between the minimum and maximum indicator lines.
Manual Section: Lubrication and MaintenanceTractor turns over slowly or clicks rapidly when trying to start the engine in cold weather p. 64
Test the battery voltage with a multimeter. Review page 64 to confirm the battery meets the minimum cold cranking ability of 420 amps at 0°F (-18°C). Clean the battery terminals with a wire brush and verify the electrolyte liquid sits exactly 1/4" (6.35 mm) above the plates.
Manual Section: Lubrication and MaintenanceLoud squealing noise coming from the front of the engine when operating at high RPMs p. 61
Inspect the fan belt for cracks or glazing. Apply 20-25 lbs. (9-11 kg) of thumb pressure midway between the pulleys. Adjust the tensioner bracket on page 61 until you achieve a fan belt deflection of 10 mm-15 mm. Tighten the mounting bolts securely.
Manual Section: Fan Belt Diagnosis and AdjustmentDifficulty shifting gears and tractor creeps forward when the clutch pedal is fully depressed p. 83
Measure the pedal movement before resistance is felt. Adjust the linkage rod on page 83 to set the clutch pedal free travel between 19 mm-30 mm (3/4"-1-3/16"). Verify the locknut is tight and test the tractor in a clear area to confirm the creeping has stopped.
