![Claas Renault Ares 547 557 567 577 617 657 697 Repair Manual [Tractor]](https://youfixthis.com/wp-content/uploads/2015/07/2015-07-07-14.51.24-300x300.png)
This is the factory repair manual for the CLAAS Ares 806 and Ares 816, the mid-2000s 6-cylinder machines built on the Renault platform with the John Deere PowerTech DPS engine. It covers the full tractor by section: engine and injection (A), powershift gearbox and clutch (B), rear axle, PTO and brakes (C), front axle and 4WD (D), hydraulics and wiring (E, F), electronic systems including the electronic lift, Electropilot and InfoTrac (G), and cab, HVAC and front linkage (H, J). You get the disassembly sequences, shim and preload procedures, hydraulic circuit descriptions and wiring item lists the dealer techs work from. If you are splitting the tractor or setting pinion bearings, this is the document you want open.

CLAAS 806-816 Common Problems This Manual Covers
Play or grinding noise from the rear axle drive pinion
Usually worn or wrongly preloaded tapered bearings. Section C, Rear Axle and Differential, gives the full removal sequence, including pulling the PTO and 4WD shaft to reach the pinion, plus the shim selection and bearing preload procedure so the repair holds.
Manual Section: C - Rear Axle, PTO & BrakesPTO clutch will not engage or will not disengage
Comes down to clutch pack wear or a hydraulic actuation fault. Section C, Rear Power Take-off, covers testing the actuation, removing the PTO clutch assembly, inspecting the friction elements and reassembling it, which is far cheaper than swapping the whole unit blind.
Manual Section: C - Rear Axle, PTO & Brakes4WD drops out or the front axle loses drive
Typically the 4WD clutch has failed or the drive shaft is binding. Section D, Front Axle and Four-Wheel Drive, shows removal of the four-wheel drive shaft and clutch, inspection points and refitting, so you can confirm which part failed before ordering.
Manual Section: D - Front Axle & 4WDGearbox locks out and will not take a gear selection
Often the internal transmission lock jams or its hydraulic release fails. Section B, Powershift Gearbox and Transmission Hydraulics, covers draining the box, the component removal order and the hydraulic circuit checks needed to free and correct the lock mechanism.
Manual Section: B - Transmission & ClutchFrequently Asked Questions
Does this manual cover the rear axle drive pinion bearing preload and shimming?
Yes. Section C walks through removing the drive pinion, selecting shims and setting the tapered bearing preload. That is the job behind the classic symptom on these tractors: play or a grinding note from the back end. The manual gives the measuring procedure and the removal order, which matters because you have to pull the PTO and 4WD shaft before you can even see the pinion.
Will it help me fix a PTO clutch that will not engage or release?
Yes. Section C covers the rear power take-off including removal of the PTO clutch assembly and its hydraulic actuation. On the Ares this clutch is a known wear item, and the manual shows how to get it out, what to inspect, and how it goes back together. It does not sell you parts, but it tells you exactly which pieces you are ordering before you split anything.
Are the electronic systems covered, or just the mechanical side?
Both. Section G covers the instrument panel, the electronic lift, Electropilot and the InfoTrac terminal with ISO socket, and sections E and F give the wiring item lists and harness routing. So when the lift acts up you can trace the circuit from the sensor to the controller instead of guessing. Keep in mind this is a repair manual, so it is stronger on wiring and component test than on plain-language fault stories.
Does it include torque values and adjustment specs?
Yes, the repair procedures include the tightening values and adjustment data for the assemblies they cover, including the rear axle and transmission work where preload and shim selection depend on getting the numbers right. That is the main reason to use the factory document instead of forum guesses: the specs sit next to the procedure that uses them.
Which tractors does this manual fit?
The CLAAS Ares 806 and Ares 816 with the DPS diesel engine and powershift gearbox. These machines started life as Renault designs before the CLAAS takeover, so the layout and section lettering follow the Renault-style factory format. If your tractor is an Ares from another series, check the model plate first, because the transmission and axle procedures differ between series.
