Part of the Case Repair Manuals.
Stripping a Case 300 tractor down to the torque tube is what this 333-page Case 300 service manual PDF, factory number 9-92002, walks you through, covering seven designations in the 300 and 400B line. Wiring diagrams run separately for the 400B, the 300 diesel on 12 volt and the 300 gasoline on 6 volt, so you trace the circuit your tractor actually left with. Hydraulic coverage runs about 50 pages, from Eagle Hitch arms that leak down overnight to a pump gone noisy under load, and the Case-O-Matic drive gets its own teardown through converter, control valve and pressure regulator. Set main bearing running clearance at .0015 to .002 inch, pull cylinder head stud nuts to 60-65 ft. lbs., and bolt the torque tube to the engine at 115 ft. lbs. Searchable text and section bookmarks mean the book goes where the tractor is, field edge included.
