This is the full factory repair set for the Cat 232B (SCH02475-up) and 232B2 skid steer with the 3024C engine: Systems Operation, Testing and Adjusting, Disassembly and Assembly, and Specifications in one 4,000-plus page file. The sections you will actually live in are all here - Basic Engine teardown (pages 46-560), the Hydraulic System with the Single Speed schematics (2239-2873), Power Train (3649-4022), Fuel System (2048-2238), and Electrical Diagnostics (1411-1913) with harness open/short tests and the full MID/CID/FMI code list. One honest note: pages 778-1234 are the Product Link/VisionLink dealer portal guide, printed twice back to back - skip past it. Everything a wrench actually needs is in the rest.
