This is the factory chassis service manual for the McCormick MC Series tractors: the MC95, MC105, MC115, MC120 and MC135. It runs 1,732 pages and is the book the dealer technician works from. It is built around the tractor itself, the transmission, hydraulics, axles, brakes, steering, cab and the electronic controllers, with full wiring and hydraulic schematics and step by step calibration and error code procedures for the hitch, MFD, differential lock, independent front suspension, speed sequencer and PTO controllers. One honest note up front: engine teardown and overhaul are not in this volume. The engine section covers removal and installation and points you to the separate McCormick Engine Service Manual SM 8-10041 for internal rebuild work. Everything else on the machine, from splitting the tractor to bleeding the brakes to charging the air conditioning, is here.

McCormick MC95-MC135 Common Problems This Manual Covers
Three point hitch is slow to lift, will not lift a heavy implement, or the hydraulics leak oil
Work the Hydraulics section. It carries a full troubleshooting routine with the system schematics split by serial number, so you can trace the fault to the charge and lubrication pump, a hydraulic valve or a worn remote valve. The book walks the pressure checks and the valve servicing in order, which is the only honest way to tell a tired pump from a stuck valve before you start replacing parts.
Manual Section: HydraulicsTractor loses power under load, stalls, or runs rough
Start in the Fuel System section to clear the tank, lines and supply, then use the General specifications to confirm the right grades and capacities. Because power loss is often inside the engine, the manual hands the injection and internal fuel work to the companion Engine Service Manual SM 8-10041, so you know exactly where the boundary is instead of guessing.
Manual Section: Fuel SystemTransmission jumps out of gear, grinds when shifting, or the powershift behaves erratically
Work the Transmission section. It covers splitting the tractor, the powershift and range transmissions, the powershift and shuttle valves and the synchronizer creep unit, and it gives the disassembly and inspection steps for the clutch packs and gears. Pair it with the Controller Systems section to read the speed sequencer and F/N/R calibration, so you pin an electronic shift fault by error code instead of tearing the box apart.
Manual Section: TransmissionHard starting, dead electronics, or a controller throwing error codes
Start in the Electrical section for battery servicing and testing and instrument cluster programming, then move to the Controller Systems section. It lists the calibration and error code procedures for every controller on the tractor (hitch, MFD, differential lock, front suspension, speed sequencer and PTO), so you read the fault, calibrate the controller and confirm the fix instead of swapping a good control unit on a hunch.
Manual Section: ElectricalFrequently Asked Questions
Does this manual cover engine overhaul on the MC Series?
No, and the manual is upfront about it. The Engine section covers removing and refitting the engine in the tractor. For the internal rebuild, pistons, bearings, injection and the rest, McCormick publishes a separate Engine Service Manual, SM 8-10041, and this chassis manual points you to it. What you get here is everything to get the engine out, plus full coverage of the rest of the machine.
How do I calibrate the controllers and read error codes?
The Controller Systems section is built for exactly that. It gives the calibration sequence, the error code lists and the troubleshooting schematics for the hitch, MFD and differential lock controller, the independent front suspension controller, the speed sequencer and the F/N/R, powershift and PTO controllers. Each one has its own programming and fault routine so you can fix an electronic fault by procedure.
Are the wiring and hydraulic diagrams included?
Yes. The Electrical section carries the full electrical schematics, and the Hydraulics section carries the hydraulic troubleshooting schematics, split by serial number so you use the right diagram for an early or late machine (the break is at P.I.N JJE2020415 / JJE2020416). These are the dealer schematics, not simplified drawings.
Which front axles does it cover?
The Transmission section covers the 20.14, 20.19 and 20.25 MFD front axles and the independent front suspension axle, including the MFD output shaft and bearings and the PTO front drive shaft. So whether your tractor has the standard mechanical front drive or the suspended front axle, the service and the controller calibration for it are both here.
