This is the factory chassis service manual for the McCormick MC Series tractors: the MC80, MC90, MC100 and MC115. It runs 2,289 pages and is the book the dealer technician works from. It is built around the tractor, 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 and the other controllers. One honest note up front: engine teardown and overhaul are not in this volume. The engine section covers removal and refitting and points you to the separate McCormick engine service manual for the internal rebuild. Everything else on the machine, from splitting the tractor to bleeding the brakes to charging the air conditioning, is here.

McCormick MC80-MC115 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: HydraulicsA loader valve responds slowly or the hydraulics feel spongy with trapped air
Start in the Hydraulics section with the remote and loader valve coverage and the charge pump. A laggy loader is usually air in the supply or a worn valve, so the section walks the bleeding and the pressure checks, and the General specifications confirm the right oil (McCormick HTX) and the fill so the system primes properly instead of staying spongy.
Manual Section: HydraulicsEngine overheats or loses power under load
Start in the Fuel System section to clear the tank, lines and supply, and use the General specifications for the coolant mix (33 to 50 percent glycol) and the 17.5 litre fill. Because power loss and overheating are often inside the engine, the manual hands the injection and internal work to the companion engine service manual, so you know exactly where the boundary is instead of guessing.
Manual Section: Fuel SystemHard 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: Controller SystemsFrequently Asked Questions
Does this manual cover engine overhaul on the MC Series?
No. The Engine section covers removing and refitting the engine in the tractor. The internal rebuild, pistons, bearings, injection and the rest, is in the separate McCormick engine service manual, 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. These are the dealer schematics, not simplified drawings.
What oils does the MC Series use?
The engine takes McCormick 15W-40 engine oil, 7 litres with a filter change, the cooling system holds 17.5 litres of a 33 to 50 percent ethylene glycol mix, and the transmission and hydraulics run McCormick HTX oil. The General section carries the full lubricant and capacity table and the master torque specifications.
