All 960 pages of this Case IH RBX452, RBX462 Repair Manual (OEM #6-71260EN) cover one machine family: the Round Baler, from driveline to tailgate. Inside you get wiring diagrams spanning the complete net-twine wrapper electrical system, harness routing, and connector pinouts, alongside hydraulic schematics for the tailgate lift, belt tension, and pickup cylinder circuits. Packed into the calibration and troubleshooting sections: error codes with controller reset procedures, component adjustment tables, and rebuild procedures covering pressing, wrapping, feeding, and ejection. Torque the rotary potentiometer to 2 Nm (18 in lbs), verify A-B resistance between 5000 and 8000 ohms, and press the stuffer weld bushing to exactly 13 mm depth before startup. Your baler's down and the season isn't waiting. Bookmarked by system and searchable by keyword; open it on your phone at the machine and get back to baling.

Case IH RBX452, RBX462, RBX452-462 Common Problems This Manual Covers
Case IH RBX452 net twine wrap controller bale diameter readings bounce erratically, full bale alarm fires prematurely p. 382
Check the rotary potentiometer resistance at the bale diameter sensor: A-B must read 5000-8000 ohms, B-C and A-C both 1000-8000 ohms (page 382). If readings jump erratically during rotation, replace the potentiometer and torque to 2 Nm (18 in-lbs). Press and hold the setup/diagnostic key two seconds to exit diagnostic mode and return to normal operation.
Manual Section: Net-Twine Wrapper Electrical System Troubleshooting - Component Adjustment and CalibrationStuffer mechanism fails to cycle or jams, hay won't feed into bale chamber p. 596
Inspect stuffer tines for bends and the drive linkage for sheared pins before pulling the assembly. Measure duckbill spring free length: replace if outside 384-390 mm (15-1/8 to 15-3/8 in). During reassembly per page 596, press bushings to 13 mm (1/2 in) depth and seals to 3 mm (1/8 in). Verify drive chain tension before cycling under load.
Manual Section: Product FeedingPersistent driveline vibration after PTO connection, hitch pin not aligned below PTO shaft p. 88
Verify the hitch pin sits directly below the PTO driveline centerline before coupling. Misalignment loads the u-joints unequally and drives the vibration you feel through the seat. Torque the PTO-to-gearbox input shaft bolt to 142 N·m (105 ft-lbs) per the driveline procedures on page 88. Inspect u-joint crosses for wear and replace any that show play when you rock the shaft by hand.
Manual Section: Implement DrivelineTailgate drifts open during baling or won't stay fully closed after latch
Check the tailgate latch sensor gap: must read 3-7 mm (1/8-1/4 in) with the gate closed and latched per page 314. Then test cylinder seal integrity: after removing pressure, the tailgate must not drop more than 254 mm (10 in) in 15 minutes. Seals that fail that test need replacing. Work through the lift system troubleshooting.
Manual Section: Tailgate Lift System TroubleshootingBale tension pressure drops mid-cycle, belts slip or won't reach maximum density p. 725
Verify belt tension system pressure: operating range is 900-2500 PSI. Connect a gauge; pressure that won't climb or drops mid-cycle points to worn cylinder seals or a failing relief valve. Inspect belts for glazing and splice failure: a laced repair shortening total belt length by 37 mm (1-1/2 in) or more per page 725 means full belt replacement.
Manual Section: Belt Tension System TroubleshootingFrequently Asked Questions
How to reset Case RBX 452 error codes?
Error messages and alarms can be cleared by pressing the CLEAR key on the operator's panel. For instance, to clear an incorrect calibration, press and hold the CLEAR key for one second until the alarm activates. Some error codes, like 'Er 1', may clear automatically after 10 seconds.
How to reset Case RBX 452 error code display
To reset the error code display, press the CLEAR key on the operator's panel. This action will cancel the audible alarm and clear the error display message. For specific calibration errors, holding the CLEAR key for one second will activate the alarm and clear the incorrect calibration.
What are the replacement specifications for Net twine wrap controller sensor?
When installing the net wrapper rotary potentiometer, torque the cap screws to 2 N⋅m (18 in lbs). For the net counter roll sensor, the distance between the sensor and the wheel magnet must be 6.3 mm (1/4″).
What are the replacement specifications for Stuffer tines and drive assembly?
When installing the pickup guard, the self-tapping screws should be tightened to 15 to 18 N⋅m (133 to 159 in.-lbs.). Ensure the stuffer tines are square to the mounting tube and properly oriented to feed material into the baler.
