Part of the Case Repair Manuals.
This is the complete factory repair manual for the Case CS100, CS110, CS120, CS130, and CS150 tractors, the CNH range that shares its engineering with the Steyr CS tractors. It is organized into the standard workshop groups and covers the machine from the WD-series diesel engine and its BOSCH injection system, through the electrical system with the combi-instrument and full schematics, the steering and the 20.20, 20.25, and independently suspended 20.25S front axles, the T 7200 transmission with the Power-Shuttle and the ECCU electronic central control unit, the PTO management, and the hydraulics in both open-center and closed-center load-sensing form with electronic hitch control. It carries how-it-works explanations, step-by-step disassembly and assembly, extensive electric and electronic troubleshooting, and hydraulic and electrical circuit diagrams, with variants split by serial-number break and by pre- and post-Power-Shuttle build.

Case CS100 – CS150 Series Common Problems This Manual Covers
Shift, forward/reverse, or PTO fault on the electronically controlled transmission
Use the electric and electronic transmission control troubleshooting and the ECCU and forward/reverse electronic-box sections. Because the transmission and PTO are electronically managed, verify the control inputs and read the electronic troubleshooting before disassembling the transmission, and confirm whether your machine is a pre- or post-Power-Shuttle build so you follow the correct section.
Manual Section: TransmissionWeak, slow, or erratic load-sensing hydraulics or hitch
Start with the high- and low-pressure circuit troubleshooting for the load-sensing system, and confirm which system your tractor has (open-center OC/LS or closed-center CC/LS). Check the load-sensing valves and, for hitch faults, the electronic hitch control (EHR-D) before replacing the pump, and use the hydraulic circuit diagrams to trace the affected circuit.
Manual Section: Hydraulic SystemHard starting, low power, or a fuel delivery fault
Work the fuel system and injection coverage: check the BOSCH injection pump feed pressures and the injectors against the manual's specifications, then follow removing and fitting the fuel injection pump if it is at fault. Confirm the fuel feed pressure before condemning the pump, since a feed or filter fault often mimics a pump problem.
Manual Section: Fuel SystemInstrument, warning, or electrical circuit fault
Use the combi-instrument how-it-works and troubleshooting section and the electrical schematics to trace the circuit, choosing the schematic set that matches your build (pre- or post-Power-Shuttle). Confirm the fault at the diagram before replacing a component, since much of the machine's control is electronic and a sensor or wiring fault can present as a component failure.
Manual Section: ElectricalFrequently Asked Questions
How do I troubleshoot a transmission or shift fault on the CS-series?
The Transmission group has extensive how-it-works and troubleshooting coverage for the T 7200, the Power-Shuttle, and the electric and electronic transmission control, including the ECCU electronic central control unit and the forward/reverse electronic box. Because the transmission is electronically controlled, work the electronic troubleshooting and check the control inputs before disassembling, and note that coverage is split between pre- and post-Power-Shuttle builds, so match the section to your machine.
Is the load-sensing hydraulic system and electronic hitch control covered?
Yes. The Hydraulic System group covers both the open-center (OC/LS) and closed-center (CC/LS) load-sensing systems, the electronic hitch control (EHR-D), the load-sensing valves for the fixed-displacement pump, and high- and low-pressure circuit troubleshooting, along with the full hydraulic circuit diagrams including the trailer-brake and four-wheel-brake variants. That gives you the complete hydraulic circuit for whichever system your tractor is built with.
Which engine do these tractors use, and is it fully covered?
The CS-series uses the WD-series diesel with a BOSCH injection pump. The Engine and Fuel System groups cover how the engine and injection system work, the disassembly and assembly, and removing and fitting the fuel injection pump, with the fuel and injection specifications. Coverage is split by serial-number break, so follow the section that matches your engine's build.
Are wiring and hydraulic schematics included?
Yes. The Electrical group includes the electrical schematics and circuit diagrams, with separate schematics for the post-Power-Shuttle build, and the Hydraulic System group includes the full hydraulic circuit diagrams for the load-sensing systems and the various brake configurations. That lets you trace an electrical or hydraulic circuit back to the diagram.
My tractor has the suspended front axle. Is it covered?
Yes. The Steering group covers the 20.20 and 20.25 front axles and the independently suspended 20.25S front axle, with how-it-works, troubleshooting, settings, and workshop procedures. Identify which axle your CS-series is fitted with and follow the matching section.
