Need factory-level repair data for your Case IH round baler? This 484-page Case IH RBX441–RBX561 Series Repair Manual (OEM #87010780) covers all four variants — the 441, 451, 461, and 561 — in one factory-sourced document. You get hydraulic schematics for the tailgate lift, belt tension, and density cylinder systems, plus a full electrical section with wiring diagrams for baler lights, electric twine wrapper, and net-twine wrapper circuits. A step-by-step troubleshooting chapter walks fault isolation across feeding, pressing, and tying systems, backed by torque tables and exploded-view assembly drawings for every major subassembly. Torque the follower roll cap screws to 91 N·m (67 ft lbs) and set the twine knife tension spring to 64 mm compressed length. Your baler is down and hay does not wait. Bookmarked by system and keyword-searchable; open it on your tablet, jump straight to the procedure, and get back to the field.

Case IH RBX441, RBX451, RBX461, RBX561 Common Problems This Manual Covers
Case IH RBX561 apron belts breaking repeatedly after 2-3 seasons, bale chamber not forming properly p. 363
Inspect all 8 belts for cuts, fraying, or splice separation per the failure analysis on page 363. On the RBX561, belts shortened more than 7.6-10.2 cm (3-4") will affect bale diameter. If one belt is short, add a 61 cm (24") section to restore proper length rather than replacing the complete set.
Manual Section: Apron Belts Belt Failure AnalysisStripper or middle roll bearing seized, belt dragging with grinding noise from pressing chamber p. 398
Remove the suspect roll and spin each bearing by hand. Drive-end bearings should rotate freely within 10-50 N∙m (84-444 in. lbs) per page 398; idler-end bearings within 6-40 N∙m (53-354 in. lbs) per page 399. Replace any bearing showing rough rotation or visible seal damage before reinstalling.
Manual Section: PressingTailgate won't close fully or drifts open after bale ejection, hydraulic pressure low p. 138
Check hydraulic system pressure against the minimum spec of 12,360 kPa. Work through the tailgate drift and pressure loss charts on page 138 to isolate whether the fault is in the lift cylinder or lockout valve. Consult the hydraulic schematic on page 110 to trace the circuit if the leak source isn't obvious.
Manual Section: Hydraulic SystemTwine wrapper not cutting cleanly or failing to tie off, loose ends on finished bales p. 439
Adjust the twine knife tension spring to a compressed length of 64 mm (2-1/2") and verify the gap between the washer and tab is 3.5 mm (1/8") per page 439. This applies to RBX451, RBX461, and RBX561. A spring set too loose lets the knife hesitate; too tight and it binds on the return stroke.
Manual Section: TyingDrive chain skipping under load, implement driveline shuddering during heavy crop intake p. 34
Measure roller chain wear elongation across a known-length span and replace any chain exceeding 3% elongation per page 34. That threshold is where sprocket wear accelerates and skipping becomes unavoidable. On the RBX441, also inspect the shear bolt hub for damage; on other models, check the slide collar quick-disconnect for engagement wear.
Manual Section: Implement DrivelineFollower roll bearing overheating or failing, belts tracking unevenly across the belt path p. 390
Pull the follower roll and test the hex bore bearing by rotating it under torque. On RBX461 and RBX561, maximum allowable rotating torque is 0.77 N∙m (6.9 in. lbs) per page 390. If the bearing spun in the cast housing, replace both the bearing and the housing together. Torque follower roll cap screws to 91 N∙m (67 ft lbs) on reassembly.
Manual Section: PressingFrequently Asked Questions
How to reset the error code on Case IH RBX baler?
To reset an error code on a Case IH RBX baler, press the CLEAR key on the operator's panel. This action will cancel the alarm and clear the error message from the display.
Torque specs for PTO shaft coupling bolts on Case IH RBX series?
For the PTO shaft coupling, tighten the nut to 142 N⋅m (105 ft lbs). This applies when installing the pin with the taper toward the center of the shaft.
What are the replacement specifications for Belts (RBX series round baler belts)?
For the RBX441, belts are six three-ply rubber covered belts with a width of 178 mm (7″) and a length of 6920 mm (272.5″), using solid steel wire with nylon cover lacing. For RBX451 and RBX461, the belts have a width of 18 cm (7″) and a length of 871 cm (343″) or 1068 cm (420″) respectively, while the RBX561 uses 8 belts with a width of 18 cm (7″) and a length of 1068 cm (420″).
What are the replacement specifications for Bearings and rollers (mounted on belt path)?
When replacing follower roll bearings, if the hex bore bearing shows signs of having spun in the cast housing, both the bearing and housing should be replaced. The hex bore bearing has a maximum allowable rotating torque of 0.77 N∙m (6.9 in. lbs).
