Fendt 711, 712, 714, 716, 815 Installation Manual – AutoSteer System

If you’ve ever tried to wire a GPS autosteer system using a generic wiring diagram you found online, you know the kind of headache that follows. Hydraulic lines misrouted. Steering valves that fight you. Calibration that never locks. That’s why this Fendt 711, 712, 714, 716, 815 Installation Manual exists. It’s the factory document – not a reprint, not a third-party rewrite. 138 pages of exactly what the dealer tech uses. No shortcuts, no assumptions.

Installation Kit Overview: What’s in the Box

Before you touch a wrench, the manual walks you through the entire kit. Steering valve components, hose kits, bracket kits – all broken down into sub-assemblies. You’ll see the exact part numbers and fastener sizes needed. The manual lists every tool required, from a #1 Phillips screwdriver to a 3500 psi pressure gauge. No guessing what you’ll need halfway through the job. Page 3 has the full tool list in a table.

Steering Valve Installation: Factory Procedure

This is where most aftermarket guides fail. The manual separates late-model valve installation from early-model. Each has its own checklist. For the Fendt 712 and 714, the relief valve adjustment procedure is critical – over-torque that valve and you’ll blow seals. The manual gives you the sequence: install the steering valve, configure it using the factory software, then test. Page 22 covers the valve configuration procedure with pinouts you won’t find anywhere else.

Does This Manual Cover the Wheel Angle Sensor?

Yes. The Wheel Angle Sensor (WAS) installation includes cutting linkage rods to exact lengths, assembling the linkage hardware, and adjusting the rod ends. The manual specifies the rod length tolerances in inches. If you cut too short, the sensor won’t read full lock. Page 41 shows the mounting bracket dimensions. No guessing.

3 Safety Warnings You Cannot Ignore

First: there is no obstacle avoidance in the AutoSteer system. An operator must always be on the tractor. Second: during calibration, the wheels swing side to side. Keep everyone clear. Third: never use AutoSteer on public roads. The manual states this in bold on page 2. Ignore these warnings and you risk injury or liability.

Connecting System Cables: The Right Way

The SA Module harness, main cable harness, roof module, display, power supply – all have dedicated connection diagrams. The manual gives a cable diagram on page 5. You’ll find the exact wire colors and pin assignments for the steering valve connection and wheel angle sensor. After connecting, you install the warning label in the cab. That’s step-by-step, not “connect as needed.”

Post-Installation: Calibration and Tuning

Once everything is bolted in, the manual leads you through relief valve adjustment, creating a new vehicle profile in the software, and calibration guidelines. You need that pressure gauge to set the hydraulic relief – spec is 3500 psi for these Fendt models. The tuning guidelines tell you how to dial in the steering response so the tractor tracks straight on contours. Without this, the system will hunt and correct constantly.

Who this manual is for: The DIY farmer who owns a Fendt 711, 814, or 716 and wants to install an OEM GPS autosteer system without paying dealer labor. You must have a basic understanding of hydraulics and wiring. The manual assumes you own the common tools listed. Beginners should have a mentor on call – this isn’t an oil change. But if you can follow a checklist and torque to spec, you can do this job.

Source validity: This is the original OEM factory installation manual from Fendt. Not a scanned reprint. Not a PDF cobbled together from forum posts. The legal disclaimer on page 2 comes straight from the manufacturer. Every torque value, every wire gauge, every valve sequence was written by the engineers who designed the system. I’ve seen third-party manuals that skip the relief valve adjustment step – that’s how you burn out a pump. Stick with the factory document.

Q: Does this manual cover the Fendt 815 model?

A: Yes. The 815 is listed on the cover along with 711, 712, 714, 716. All installation procedures apply.

Q: What torque specifications are given for the steering valve mounting bolts?

A: The manual states the torque for the steering valve mounting bolts in the Steering Valve Installation Checklist. The exact value is provided in inch-pounds for the ¼-20 bolts – you must refer to page 26 in the manual. I will not guess the number. If you lose it, you strip the threads.

Q: Is there a section on connecting the battery power?

A: Yes. The main cable harness section covers battery power connection, cab power connection, and power supply connection. It includes a wiring diagram with fuse ratings. Follow it exactly – reverse polarity will fry the SA Module.

Q: Can I use this manual if I have no experience with hydraulics?

A: The manual assumes you have basic hydraulic knowledge. You need to adjust a relief valve and connect steering valve hoses. If you cannot identify a pressure gauge or understand hydraulic flow, get help. The manual includes safety notes but will not teach you hydraulics from scratch.

One last thing: the Final Hardware Installation Checklist on the last page catches every nut and bolt you might have left loose. Use it. When you’re ready to get the job done right, Download the Factory Manual and have it on your tablet next to the tractor. No more guessing, no more aftermarket errors.
