PDF Search, Navigation and Page Count

Search and diagram access: Body text is searchable, and embedded PDF bookmarks link to the main sections. Labels within several diagrams are not searchable. The powershift hydraulic schematic and control-valve section view retain German annotations; small labels are best read at higher zoom.

One printable 410-page PDF, including the cover, publication information, three blank separator pages, and four pages containing only running headers.

Transmission, Clutch and Axle Repair

These selected repair topics sample the manual’s contents. Further subjects include rear PTO vibration-damper retrofits and gearshift interlock assembly.

• Turboclutch: Removal and installation, bearing inspection, shaft-seal replacement, and illustrated reassembly of the fluid coupling.

• Powershift transmission: Step-by-step clutch-pack disassembly and reassembly, bearing adjustment, control-valve repair, and forward/reverse valve-block service.

• Manual transmission: Synchromesh inspection, pinion-shaft setup, gearshift adjustment, and Hare/Tortoise range-shift assembly.

• PTO systems: Rear PTO clutch and gear-train repair, shaft replacement, front PTO overhaul, and clutch-disc inspection.

• Four-wheel drive and final drives: Clutch engagement checks, disc replacement, differential-lock repair, and variant-specific axle-drive overhaul.

• Brake systems: Solid-disc brake inspection and adjustment, cardan-shaft brake repair kits, master-cylinder service, and model-specific bleeding procedures.

Written for trained staff at Fendt dealerships, this manual assumes access to standard workshop tools and equipment, with special tools identified where required.

Powershift Diagnosis and Assembly Details

The powershift unit contains six clutches, arranged as C/A, D/B, and G/F. Power-flow charts, the hydraulic circuit diagram with operating tips, and control-valve sectional drawings connect the internal assemblies with their operating functions.

The control-valve section addresses hard shifts and momentary loss of traction during shifting through piston and diaphragm selection. It also distinguishes older and newer solenoid valves that are not interchangeable.

A compressed-air leak check identifies sealing problems after reassembly, including rectangular-section rings damaged during installation. The turboclutch instructions separately highlight assembly positioning that prevents a shaft seal from turning inside out.

Control-system coverage: Electronic and hydraulic powershift control information is assigned to separate training brochures: X 990.005.023.019 for Favorit and X 990.005.023.024 for Xylon. Those brochures are not included in this PDF.

Tractor Splitting and Gearbox Setup

Separate procedures distinguish Favorit tractor splitting from Xylon transmission removal, including differences between standard and local-authority bodywork. The illustrated disconnection and refitting procedures support major drivetrain work within an equipped repair shop.

Bearing settings, pinion-depth calculations, crown-wheel backlash checks, and gear-tooth contact patterns provide the setup information needed after internal repairs. The manual specifically notes that joint-gasket thickness affects the pinion reference dimension.

Scope and handling: Xylon engine/front-axle separation is not illustrated, and engine repairs require the separate Engine Manual. Tractor splitting and axle removal require securely supported assemblies and suitable lifting equipment.

PTO, Brake and Axle Variants

Rear PTO coverage distinguishes the 750/1400 and 540/1000 gear arrangements, including conventional and flanged PTO shafts. Front PTO sectional views show the clutch assembly, while separate illustrations distinguish season-control versions I and II.

The axle-drive chapters separate the larger and smaller drive assemblies and their bearing arrangements. Xylon wet-brake procedures distinguish sintered-metal and organic linings by chassis number, helping match the assembly instructions to the installed brake version.

Fluid requirements: Favorit brakes use the specified oil-free brake fluid, while the Favorit clutch system uses Pentosin CHF 11S. Xylon brake and clutch systems use Pentosin CHF 11S. The lubricant tables also distinguish HD SAE 10W turboclutch oil from STOU transmission oil.

General reference tables cover engine-oil and coolant capacities, hydraulic fluids, and metric standard- and fine-thread tightening torques in Nm and kpm. The special-tool section identifies equipment such as pressure-test kit X 899.980.161 and powershift clutch press bush X 899.980.223, alongside drawings for workshop-made fixtures.

Examples of Clutch Test and Clearance Data

For the covered Favorit and Xylon models, the drive-clutch pressure check gives 28–30 bar as a guideline with a new clutch during pedal operation. The text notes a slight pressure drop when the pedal is fully depressed.

For the rear PTO clutch, the specified ventilation gap is 2.5–4.0 mm with the disc set pressed centrally. The inspection guidance associates a gap below the minimum with dished discs.
