Using these diagrams alongside the text in this manual will make diagnosis and repair much easier.
The diagrams are organized by major systems, such as the engine, transmission, hydraulic system, and electrical system. Each diagram includes labels identifying the key components within that system. Use these diagrams in conjunction with the parts catalog to identify and order the correct replacement parts. Remember to always disconnect the battery before working on the electrical system to prevent accidental shorts or damage.
While these diagrams are as accurate as possible, there may be minor variations depending on the specific configuration of your tractor. Always refer to the specific serial number of your tractor when ordering parts or consulting service information. Serial number-specific information ensures you are working with the correct documentation for your machine. Contact your CASE IH dealer for any questions regarding component locations or system configurations.
