Case RB454, RB464 Common Problems This Manual Covers
Case RB454 chevron belt fraying, edge wear, and tearing during heavy pressing cycles p. 691
Inspect torn belts for surface damage. If replacing sections, trim the rough top to a skiving depth of 5 mm (0.2 in) as detailed on page 725. For complete replacement on 1524 mm (60 in) diameter bales, cut new belts to exactly 8712 mm (343 in) on page 691.
Manual Section: SECTION 62 - PRESSING, Chapter 2 - Belts, Belt Failure AnalysisSluggish bale rotation and loud slipping noises from the sledge drive slip clutch p. 9
Inspect the sledge roll drive slip clutch for glazed or burned linings. Measure the breakaway torque. Adjust the spring tension until the clutch slips exactly between 677 to 767 N·m (500 to 567 lb ft) as shown on page 9. Replace the friction discs if torque cannot be maintained.
Manual Section: Implement DrivelineLoud grinding noise from the front PTO drive shaft and gearbox input connection p. 75
Drain the gearbox and inspect for metal shavings. Measure the gearbox backlash on page 75, ensuring it stays between 0.18 to 0.48 mm (0.007 to 0.019 in). Refill the housing with 0.65 L (22 oz) of 80W-90 API GL5 gear oil as specified on page 59.
Manual Section: Implement DrivelineNet wrapping fails to cut cleanly or uneven tension causes loose wrap on bales p. 9
Check the net brake system linkages for binding. Measure the net wrapper brake pad thickness. Replace the pads immediately if they wear below the minimum specification of 2 to 4 mm (3/32 to 5/32 in) listed on page 9. Adjust the brake spring tension to ensure proper cutting action.
Manual Section: SECTION 68 - WRAPPING, Chapter 1 - Net Wrapper Mechanical System AdjustmentsFrequently Asked Questions
How to reset twine arm error on Case IH RB454?
The manual indicates that the "Er 1" error code, which signifies a net or twine actuator failure for 5 seconds or more, will clear itself automatically after 10 seconds. There is no manual reset procedure specified for this particular error.
What are the torque specs for belt tension bolts on RB464?
The manual does not provide a specific torque specification for "belt tension bolts" on the RB464. However, for the RB464 with clutch, it instructs to tighten the two set screws, 3, and jam nuts, 2, without specifying a torque value.
What do error codes E10 and E25 mean on RB454 baler computer?
The manual does not list specific error codes E10 or E25. However, it describes various error messages and diagnostic items, such as "Er 1" for net or twine actuator failure and flashing indicators for bale shape or wrapper issues.
How to reset twine arm automatic tie on Case IH RB454
The manual does not provide a specific procedure to "reset twine arm automatic tie" on the Case IH RB454. However, it details adjustments for twine tension and twine tube breakaway, and troubleshooting steps for the net-twine wrapper electrical system, which may involve checking sensors and actuators.
