Fendt 700/800 Vario Tractor Workshop Manual 1998–2006 (P/N X990.005.051.010)

The Fendt 700/800 Vario Workshop Manual, P/N X990.005.051.010, is the August 2006 edition for the 711, 712, 714, 716, 815, 817, and 818 within the 1998–2006 Vario family. Title-page chassis limits identify the later configurations; included earlier Favorit 700 worksheets retain their own component and chassis applicability.

Text Search, Bookmarks and Diagram Detail

Navigation and small labels: Searchable text and embedded bookmarks cover both book sections. Labels embedded in diagram images are not searchable, and small wiring and hydraulic symbols require zooming. The English edition includes German electrical-identification pages and some German diagram labels.

One printable PDF contains 1,246 pages: Book 1 has 786 pages and Book 2 has 460. Both original title pages are included in that total.

Vario Drivetrain, Hydraulic and Electronic Repair

These coverage highlights represent selected workshop content. Other sections include compressed-air trailer-brake testing and instructions for releasing electrical connector contacts.

• Engine service: Valve-clearance adjustment, cylinder-head-gasket selection and replacement, injection-pump and injector replacement, fuel-system testing, and lubrication-pressure checks.

• Transmission and final drive: Vario drive removal and installation, pinion/ring-gear and differential work, axle-drive removal, front-wheel-drive clutch repair, and Hydrodamp service.

• Brakes and PTO: Rear and cardan-shaft brake repair, hydraulic bleeding, front-PTO clutch and pump service, live-PTO clutch work, and speed-preselection repair.

• Hydraulics and power lift: LS-pump diagnosis, SB 23 LS-EHS valve repair, front-power-lift installation, rear EPC troubleshooting, and B030 position-sensor replacement.

• Calibration: Rear EPC, front power lift, auxiliary valves, suspension, PTO engagement, clutch pedal, hand/foot throttle, operating-range sensing, transmission characteristic, turboclutch, and joystick settings.

• Electrical diagnosis: Fault-code tables, ECU pin assignments, sensor and actuator measurements, CAN-bus testing, and FENDIAS/SERDIA and Vendi diagnostic procedures.

Written for trained tractor technicians, this manual assumes normal workshop equipment and the specified special tools are available.

Chassis Differences and Worksheet Selection

The model-history tables matter because the same badge does not always mean the same hardware. They distinguish ML 130/160 transmissions, HA 110/130/160 rear axles, and ZF APL-2000/F6/F7 and DANA 735-110/745-110 front axles.

Separate entries identify Bosch EPC-C and EPC-OBE lift control, centrifugal and EMR 2 engine control, and Variotronic 1.0, 2.0, TI/TMS, and TI/TMS Generation 2. These distinctions help match parts, settings, and procedures to the tractor.

The September 2004 update identifies FENDT 700 Generation 4 and FENDT 800 Generation 2, including stepless roof-blower control and external auxiliary-valve actuation. Earlier Favorit worksheets supplement that coverage according to their individual validity limits.

Engine Repair and Its Limits

The DEUTZ BF6M 2013 C sections explain cylinder-head-gasket selection from piston projection and injection-pump setup using the engine’s EP data. Step-by-step procedures cover the documented gasket, pump, and injector work.

For further internal engine repair, the manual explicitly refers to the separate Deutz 2012/2013 Engine Workshop Manual, X990.005.034. That companion publication is not included.

Transmission, PTO and Brake Details

Transmission diagnosis combines PTO power measurement with hydraulic-pressure records to distinguish engine power loss from a traction-drive fault. The pressure-report forms support comparison before and after repair.

The repair worksheets extend into high-pressure relief and flush-valve service, clutch-disc inspection, and PTO selector adjustment. Live-PTO instructions distinguish revised selector gearing and warn that bell-housing removal can damage the externally toothed clutch plates; disc-stack groove alignment is also specified.

The filtered external oil-filling unit X899.980.255.000 is required whenever the ML high-pressure circuit has been opened. The manual explains its role in preventing the hydraulic pump and motor from running dry.

Brake and clutch hydraulics use Pentosin CHF 11S, order number X902.011.622. The repair instructions expressly prohibit conventional brake fluid.

Hydraulics, EPC and Calibration

Hydraulic coverage follows the LS pump, steering priority circuit, central control block, and auxiliary valves through pressure-measuring locations, test records, and component diagrams. Working-hydraulic data distinguishes the 200 bar system from the 22 bar control-pressure circuit.

SB 23 LS-EHS documentation includes valve-number assignment, pilot-valve replacement, microfilter service, and shutoff-valve work. Earlier and later CAN-bus valve versions are distinguished because identical operating functions do not make the valves interchangeable.

On the rear EPC, an overly tight lift setting can twist the linkage near the top of its travel and overload the B031/B032 draft-sensing pins. The associated overload fault is not stored.

Before hydraulic or drivetrain work, follow the manual’s pressure-relief and workshop-safety requirements. Front-suspension accumulators can remain pressurized with the engine stopped and the suspension lowered or locked.

Fault Tracing, Schematics and Diagnostic Equipment

Fault-code tables connect component identifiers and fault conditions with expected machine behavior and the relevant test or diagram references. A008 terminal diagnostics show IDEAL/VE/REAL transmission-ratio values, B008 high-pressure readings, discharge temperature, CAN status, and ISO/LBS bus data. Terminal readings do not replace physical pressure or electrical measurements.

FENDIAS/SERDIA coverage includes EMR 2 fault memory, live values, output tests, ECU data-set programming, and load-spectrum records. Output testing and programming require the specified SERDIA access level. Vendi reads individual Bosch EHS 23 LS valve faults with operating hours, control-unit temperature, and fault frequency.

Included illustrations comprise the transmission hydraulic schematic, EPC 23-OBE sectional and circuit views, hydraulic circuit diagram with key, Hall-effect sensor circuit, and CAN-bus terminal-test wiring. The separate 9000/C wiring-diagram section referenced by the worksheets is not included; component circuits, connector views, and electrical test tables are provided.

Some fault entries also refer to separate EPC/ML service-training literature. Equipment references include the X899.980.260.102 EMR SERDIA diagnostics box and X899.980.249.100 hydraulic-pressure measuring case.

Cab, Air Conditioning and Service References

Cab procedures cover tilting, lowering, and applicable pneumatic-suspension installation. Air-conditioning documentation covers Refrigerant 134a, S035 high/low-pressure switching, and sensor/thermostat tests. Evacuation and charging are referred to the filling-equipment manufacturer’s instructions.

The compressor-belt specification is 400 +50 N strand force for the 13 mm profile, measured midway between the pulleys with an Optibelt tension gauge.

Fluid tables list approximately 16.5 L engine-oil capacity with a filter change, transmission/differential refills of 45 L for the 700 Vario and 50 L for the 800 Vario, and 0.8 L for brake/clutch hydraulics. They also provide lubricant specifications and maintenance intervals, with a direction to consult the chassis-matched operator’s manual for applicable current values.

Wheel-torque tables specify 275 Nm front / 450 Nm rear for the covered 700 Vario configurations and 450 Nm front / 580 Nm rear for the 800 Vario, with threads and locating faces lightly oiled.

Examples of Engine Adjustment and Test Data

For the BF6M 2013 C, the engine-data tables specify cold valve clearances of 0.4 mm intake and 0.5 mm exhaust, alongside the valve-adjustment procedures.

The same tables list injector opening pressure as 250 +12 bar and new-engine compression pressure as 28–32 bar. These entries distinguish adjustment data from pressure specifications and complement the engine’s diagnostic and service sections.
