This is not a condensed or aftermarket summary — it is the full Case IH service documentation for the Maxxum Multicontroller and CVT Tier 4B platform, published by CNH Industrial Österreich GmbH. Every major assembly and circuit on these tractors is addressed with removal, disassembly, inspection, assembly, installation and testing procedures where applicable.

What This Manual Enables You to Do

The Case IH Maxxum 115-150 Tier 4B is a complex machine with electronically controlled hydraulics, a load-sensing variable displacement pump, CAN bus networked control modules, Selective Catalytic Reduction emissions equipment and, on CVT models, a continuously variable transmission with hydrostatic and mechanical power paths. Servicing any of these systems without the correct procedures, torque values and calibration steps risks damage to expensive components and unsafe operation.

With this manual you can:

• Diagnose and repair hydraulic faults across the reservoir, cooler, filter, pump, priority valve, remote valves and hitch control systems
• Remove, overhaul and reinstall the fixed displacement pump, variable displacement pump and charge pump with correct torque values and inspection criteria
• Service the three-point hitch control valve and cylinder, including calibration procedures
• Troubleshoot and repair the electrical system — alternator, battery, harnesses, sensors, solenoids, relays, fuses and control modules
• Work through the complete electronic module diagnostic H-menu system, including calibration procedures, fault code display and clearing, switch tests, voltmeter diagnostics and configuration options
• Service the transmission control system, speed sensors, pressure sensors, temperature sensors and position sensors on both 16×16 and CVT transmissions
• Diagnose and repair the SCR/AdBlue emissions system and its sensors, dosing module and supply module
• Remove and install the electronic park lock actuator and perform calibration
• Service the steering system, including fast steering control and autoguidance
• Overhaul the front and rear wheels and understand the correct torque values for wheel nuts
• Repair cab climate control systems including heating, ventilation and air conditioning
• Remove and install the front frame and understand the correct shim clearances
• Service the rear three-point hitch linkage

Why This Manual Matters

Case IH Maxxum tractors are high-value machines used in demanding agricultural work. Correct service procedures, accurate torque values and proper calibration are essential to keep them reliable, safe and productive. Using generic or incomplete information can lead to premature failure of hydraulic components, transmission clutch damage, emission system faults and costly downtime.

This manual provides the exact specifications, step-by-step procedures and diagnostic routines that Case IH technicians use. It covers both the Multicontroller and CVT variants, and every major system on the tractor is documented. The fault code index alone makes this an essential reference for diagnosing electronic faults across the engine, transmission, hydraulics, brakes, steering and auxiliary controls.
