Case IH 115, 125, 135, 145 Maxxum Cvx Tractor Pdf Service Manual (Stage Iv 2019)

Case IH 115, 125, 135, 145 Maxxum CVX Tractor PDF Repair Service Manual (Stage IV 2019) (PIN ZXEX50001 And Above) (EU)

Before a technician reaches for a wrench, the first task in a Case IH dealership is identifying the exact tractor configuration. Although the Maxxum 115, 125, 135 and 145 CVX models share the same platform, each machine can differ in software calibration, hydraulic configuration, PTO equipment, electronic options and steering functions. Correct identification ensures that every diagnostic test, calibration routine and repair procedure matches the tractor being serviced.

This OEM Factory Repair Service Manual has been developed for the complete 2019 European Stage IV Maxxum CVX family beginning with PIN ZXEX50001 and above. Rather than providing basic maintenance advice, it delivers dealership-level workshop procedures covering inspection, troubleshooting, calibration, component removal, overhaul and final verification. Whether the tractor is used for precision drilling, grassland management, transport or intensive loader operations, this manual provides the technical information required to restore factory performance while reducing unnecessary downtime. The publication covers the CVXDrive transmission, engine systems, hydraulics, MFWD axle, PTO, steering, electronic controls, cab systems and chassis assemblies.

Machine Information

Why CVXDrive Requires Precision Diagnostics

Unlike stepped transmissions that rely on fixed gear ratios, the CVXDrive system continuously balances engine speed and travel speed through hydro-mechanical power transfer. Hydraulic regulation, transmission software, controller communication and sensor accuracy all influence machine performance. For this reason, dealership technicians verify live operating data, hydraulic pressures and calibration status before considering mechanical disassembly.

The workshop procedures follow the same logical sequence used in professional service departments. Each repair begins with system verification, continues through inspection and calibration, and concludes with operational testing to ensure the transmission, hydraulic system and electronic controls work together within factory specifications. This structured approach improves repair accuracy while helping prevent repeat failures. CVXDrive is designed to provide seamless acceleration and automatically maintain the most efficient engine speed for varying field and transport conditions.
