Case IH RBX452, RBX462, RBX552, RBX562 Common Problems This Manual Covers
Case IH RBX series chevron belts crossing, flipping over, or tracking sideways off rolls p. 756
Inspect each belt for twisted hooks, missing chevrons, and frayed edges at page 756. Spin every roll by hand: a single seized bearing throws belts off track within one bale cycle. Verify density cylinder pressure drops to zero between bales. Repair damaged sections up to 1830 mm (72") maximum; replace any belt that won't hold that length.
Manual Section: PressingBale core won't form or hay refuses to catch and start turning inside the chamber p. 928
Check floor rolls and the starter roll for smooth rotation and worn surfaces. A roll worn past usable diameter loses grip and hay slides through without catching. Remove the left shield, spin each roll by hand, and feel for roughness or flat spots. After starter roll service, torque the sprocket retaining bolt to 97-103 N⋅m (72-76 ft. lbs.) per page 928.
Manual Section: PressingDry or brittle hay won't catch on belts and bale refuses to start turning p. 133
Reduce ground speed first, then check the Main Drive Slip Clutch for glazed or worn friction discs. On RBX452, RBX462, and RBX552, verify clutch torque is within 1020-1380 N⋅m (752-1018 ft.-lbs.) per page 133; a slipping clutch drops belt speed exactly when dry hay demands maximum grip. Inspect belt chevrons for polishing or glazing at page 756.
Manual Section: Implement DrivelineNet wrap error code active or wrap cycle fails to complete and net tears mid-cycle
Check the net wrap solenoid connector for corrosion or pushed-back pins first. Pull fault codes to confirm whether the fault is electrical or mechanical. Inspect net wrapper brake pad clearance: correct gap is 2 to 4 mm (3/32 to 5/32") per page 49. A dragging brake stalls the wrap cycle even with a functional solenoid.
Manual Section: Net-Twine Wrapper Electrical System TroubleshootingTailgate won't lock closed after bale ejects or drifts open under load
Test the tailgate lockout valve for internal leakage. A drifting tailgate after ejection almost always traces to a bypassing valve or worn cylinder seals, not the latch mechanism. On RBX462 and RBX562, check tailgate roll bearings for play; torque lower tailgate roll nuts to 97 N⋅m (72 ft. lbs.) per page 900 after any roll service.
Manual Section: Tailgate Lift System TroubleshootingFrequently Asked Questions
How to reset bale pressure on Case IH RBX baler?
To adjust the bale density pressure, lower the tailgate, then loosen the lock on the right rear of the baler. Turn the knob clockwise to increase pressure or counterclockwise to decrease it. Open the tailgate again and check the pressure, repeating until the desired pressure is achieved, then tighten the lock. For RBX462, the maximum pressure is 2500 psi, and for RBX562, it is 2000 psi.
How to clear error codes on Case IH RBX round baler
To clear error codes on a Case IH RBX round baler, press the "CLEAR" key on the operator's panel. This action will cancel the audible alarm and clear the error display message, as well as the daily bale count. For instance, if an ERROR message appears due to the tailgate being open for 15 seconds or more, pressing the Clear key will clear it.
How to reset net wrap timer on Case IH RBX562
The manual refers to "Duckbill dwell time" as an adjustment for net feeding, which can be set between 4 and 15 revolutions of the net counter wheel before the duckbill retracts. To adjust this, enter the setup/diagnostic mode, navigate to item 23, and use the plus (+) or minus (-) keys to change the value within the 12-15 range.
What are the replacement specifications for Chevron belts?
The replacement specifications for belts on Case IH RBX balers depend on the baler size. For a five-foot diameter baler, the belt length is 8712 mm (343″) and the width is 178 mm (7″). For a six-foot diameter baler, the belt length is 10671 mm (420″) and the width is 178 mm (7″).
Is this Case IH RBX452–RBX562 Series Repair Manual a digital download?
A 1040-page Repair Manual in searchable PDF format, available the moment you complete checkout. View on computer, tablet, or phone, with no shipping wait.
