Case IH 115, 125, 135, 145 Maxxum Cvt Tractor Service Pdf Manual (Tier 4b Final 2019)

Case IH 115, 125, 135, 145 & 150 Maxxum Multicontroller Tractor Service PDF Manual (Tier 4B Final 2019)

Built for modern mixed farming operations where one tractor must perform loader work in the morning, transport grain in the afternoon, and operate precision field equipment throughout the season, the Case IH Maxxum 115, 125, 135, 145, and 150 Multicontroller tractors combine advanced electronic controls with proven mechanical durability. Equipped with the intuitive Multicontroller armrest, Semi-Powershift 16×16 transmission, high-capacity load-sensing hydraulics, and Tier 4B Final emissions technology, these tractors deliver excellent operator productivity while maintaining efficient power transfer in demanding agricultural applications. This OEM factory service manual covers the 2019 Stage IV / Tier 4B Final models and provides dealership-level repair procedures for professional servicing.

Unlike general workshop guides, this manual is organized around complete diagnostic and repair workflows. Every section begins with fault diagnosis before progressing through inspection, pressure testing, calibration, component overhaul, and post-repair verification. Whether you're troubleshooting the Semi-Powershift transmission, recalibrating electronic hitch controls, repairing the hydraulic system, or servicing the front axle suspension, the procedures follow official Case IH workshop standards developed specifically for the 2019 Maxxum Multicontroller platform.

Developed for Precision Farming and Heavy Utility Operations

The 2019 Maxxum Multicontroller Series was designed for operators who regularly switch between field cultivation, precision planting, mowing, baling, loader applications, and road transport. The Multicontroller armrest allows simultaneous control of transmission, hydraulics, PTO, and headland functions, while the electronically managed hydraulic system delivers smooth implement control. This workshop manual explains how these integrated systems communicate and how they can be repaired and recalibrated after servicing.

This factory manual includes diagnostic flowcharts, calibration procedures, hydraulic schematics, connector identification, torque specifications and detailed exploded illustrations that help technicians identify root causes quickly while restoring factory operating performance.

Frequently Asked Questions

The Multicontroller buttons respond intermittently while the transmission continues operating normally. Does this manual explain controller diagnostics?

Yes. Dedicated electrical chapters explain Multicontroller switch testing, CAN-Bus communication diagnostics, connector inspection, controller calibration, and wiring verification to isolate faults without unnecessary component replacement.

Our Maxxum 145 loses hydraulic lifting power only when operating multiple remote valves. Can this manual identify the source?

Absolutely. Factory diagnostic procedures cover load-sensing pump performance, hydraulic pressure testing, priority valve inspection, remote valve diagnostics, and internal leakage checks to accurately identify hydraulic performance issues.

After replacing transmission components, is recalibration covered in the workshop manual?

Yes. The manual includes transmission calibration routines, clutch engagement adjustments, hydraulic pressure verification, controller setup procedures, and post-repair operational testing required after servicing the Semi-Powershift transmission.

Does this manual include complete electrical wiring diagrams for the 2019 Tier 4B Final models?

Yes. Complete OEM wiring diagrams, controller layouts, CAN-Bus communication schematics, sensor testing procedures, connector locations, and electrical troubleshooting charts are included specifically for the 2019 Maxxum Multicontroller tractors.

Why is this manual especially valuable for workshops servicing the 2019 Maxxum Multicontroller Series?

Because it combines advanced electronic diagnostics with detailed mechanical repair procedures specifically for the Tier 4B Final 2019 models. From transmission calibration and hydraulic testing to PTO servicing, MFWD repairs, controller diagnostics, and wiring diagrams, it provides the complete technical information required to restore factory performance and maximize tractor uptime.
