Fendt 816, 824 1998 Training Manual

Hands down, the quickest way to waste a full day on a Fendt 816 or 824 is to guess your way through the comfort gear hydraulics. I’ve seen guys burn three hours chasing a pressure drop that turned out to be a blocked suction filter – a check that’s laid out on page 2 of the factory training manual. This Fendt 816, 824 1998 Training Manual is not a reprint of some aftermarket interpretation. It’s the original OEM document used to train Fendt technicians. 236 pages, bound in a PDF that prints clean on any shop computer.

Comfort Gears and Pressure Measurements

First thing you’ll find after the title page is the comfort-gear section – position of components and pressure measurement points. The manual tells you exactly where to hook your gauge for system pressure checks, and it walks through the procedure to increase system pressure from gearbox number 27/1 onward. Hydraulic circuit diagrams for both the comfort gears and load gears are included, so you can trace oil flow without pulling a valve body apart blind.

Does This Training Manual Cover the Load Gears?

Yes, and it does it properly. Section 3, “Load Gears – Position of Components, Pressure Measurements, Towing Specifications,” gives you the tow limits and the test report sheet that a good shop fills out after a rebuild. The 4LG control block removal and replacement is covered stepwise. If you’re dealing with a Favorit 816 or 824 that won’t shift into field mode, the function diagrams for changeover gears (section 7) will save you from replacing solenoids that aren’t actually bad.

Fault Code Retrieval and Emergency Operation

Electrical ghosts are the worst. This manual includes the full fault code table (section 16) and the procedure for retrieving codes through the onboard computer. It also covers emergency running with the E-Adapter box and emergency operation of turning gears and load gears. For tractors up to Basic E-Box Number G 816.970.070.013, there’s a dedicated emergency operation section. You also get the CAN-Bus circuit diagram and block diagrams for the E-Box.

Circuit Diagrams: Which Systems Are Included?

Circuit diagrams start on page 113 and run for roughly 60 pages. They’re split by vehicle serial number – up to 2000 and from 2001 – because Fendt changed the wiring mid-production. Coverage includes starter control, E-Box supply, combi-instrument, load gears, road-field mode, 4WD/diff lock, PTO gears, attachment socket, springing, flasher system, lighting, heating, wipers, cold start (flame start), engine brake/shut-off, horn, working lights, ventilation/AC, cab lighting, radio, and sockets. Also includes the turbo clutch monitoring circuit and engine additional equipment diagrams.

Why Use a Factory Training Manual Instead of Aftermarket?

I have a stack of aftermarket manuals on the shelf that I use for doorstops. They skip the diagnostic flowcharts, leave out the emergency operation steps, and the wiring diagrams are redrawn by someone who never touched a Fendt. This training manual is original OEM content – the same binder that Fendt issued to dealer techs in 1998. You get the actual hydraulic circuit diagrams, the correct pressure measurement points, and the exact fault code table. No guesswork, no translations that lose meaning.

What torque values are in this manual?

This is a training manual focused on system operation and diagnostics – hydraulic pressures and electrical tests. It does not replace a factory service manual for bolt torque specs.

Does this manual cover both the 816 and 824 models?

Yes, both the Favorit 816 and 824 are covered.

Is this the same as a service manual?

It’s a training manual, so it emphasizes understanding how the systems work – comfort gears, load gears, PTO, brake system, and electronics – rather than step-by-step engine overhaul. You will find maintenance and adjustment procedures, but it’s not a full service manual.

Can I use this for troubleshooting transmission issues?

Yes, especially for comfort gear and load gear problems. The pressure measurements, hydraulic diagrams, and fault code tables are exactly what you need to diagnose shifting issues. Towing specifications and emergency operation procedures are also included.

After 28 years in this trade, I can tell you that a Fendt Favorit 816 or 824 is a good machine when you treat it right. Treat it wrong – using generic wiring schematics or skipping the gearbox pressure test – and you’ll be splitting the tractor twice. The factory training manual is the reference that keeps your hours billable and your reputation clean. Download the Factory Manual and put it on your shop tablet tomorrow morning.
