Part of the Case IH Repair Manuals.
A knotter that starts throwing loose bales in the middle of baling season will not wait for a dealer opening. The Case IH LBX331, LBX421, LBX431 repair manual PDF, OEM document 87019910, answers that with 888 pages of factory service work covering all three square balers. Wiring diagrams, electronic module troubleshooting, and error code references take up roughly a third of the book, and hydraulic schematics trace the bale density, pickup lifting, and blade control circuits valve by valve. Teardown procedures run from the pickup and stuffer through the plunger, knotter drive, and twine needles. Before you torque the PTO driveshaft pinch bolt to 70 Nm, set the locking collar at 62 mm, straight from the spec table. Guessing that slip clutch figure shears parts, not twine. Bookmarked and text searchable, this PDF is bought once and yours for the life of your baler.
