Part of the Case Repair Manuals.
A 2555 that drops a drum drive in the middle of picking season does not care what the dealer's schedule looks like. The Case 2555 service manual PDF, factory publication 7-88071, answers with 716 pages of shop procedure written for the Cotton Picker by the people who built it. Separate wiring schematics cover machines before and after P.I.N. JJC0157150, so the harness you trace matches your serial number. Hydrostatic drive pump and motor service, transmission work, picker drum removal, and a full hydraulic troubleshooting section with its schematic share the book with air conditioning gauge testing. Torque the wheel mounting bolts to 140 to 160 pound feet and set the idler spring gauge clearance at 0.060 to 0.100 inch, straight from the tables. Harvest windows close whether the picker runs or not. Bookmarked and text searchable, this download puts the right spec in front of you the first time.
