22007- Fendt 700/800 Vario COM III Tractor Workshop & Fault Code Manual Set (P/N X990.005.055.010, X990.005.448.013)

This Fendt 700/800 Vario COM III Manual Set pairs the October 2007 workshop manual, P/N X990.005.055.010, for the 712, 714, 716, 718, 818, and 820 with the October 2008 Vario fault-code tables, P/N X990.005.448.013.

• Engine and fuel system: Common-rail and EDC 7 diagnostics, injector removal and installation, fuel-system bleeding, lubrication-pressure testing, and valve-clearance adjustment.

• Vario drivetrain: Transmission-unit removal and installation, pressure testing, differential and ring-gear repair, axle-drive service, and four-wheel-drive clutch repair.

• PTO and brakes: Front and live PTO clutch disassembly and assembly, PTO pump service, rear wheel brake repair, cardan-shaft brake work, and hydraulic bleeding.

• Hydraulics and power lift: LS pump troubleshooting, hydraulic pressure measurements, SB 23 LS-EHS control-valve service, and EPC-OBE power-lift diagnosis.

• Suspension and steering: Front suspension troubleshooting and sensor calibration, Auto-Guide steering calibration, and pneumatic cab suspension documentation.

• Electrical diagnosis: System wiring diagrams, connector pin assignments, component locations, CAN-bus tests, and fault tables with causes and operating consequences.

• Workshop references: Metric and fine-thread bolt torque tables, fluid specifications, measurement forms, and illustrated special-tool references.

The workshop manual is written for trained mechanics in equipped repair shops and assumes familiarity with routine repair work.

Engine Diagnostics and Repair Coverage

The fuel-return pressure test uses SERDIA target-versus-actual rail-pressure readings to help distinguish fuel-feed problems from restricted return flow before components are replaced. The documentation identifies the required USB diagnostic interface and SERDIA testing box X899.980.260.102.

Engine scope: The included work covers fuel-system components, sensors, and valve adjustment. Full internal engine overhaul requires the separate Deutz TCD 2012 workshop manual referenced in the engine section; that publication is not included.

The Y094 EGR actuator notes explain how switching on the ignition with its linkage disconnected can overrun the calibration stops and damage the actuator.

Transmission, PTO, and Hydraulic Repairs

Repair data is organized by assembly, with separate registers for faults, testing, settings, and repair. Differential procedures include pinion-shaft shimming and bearing adjustment; PTO sections show clutch-disc arrangements and seal installation. Rear brake documentation includes exploded component drawings.

The pinion-shaft removal instructions identify the support frame needed to prevent transmission-housing damage during pressing operations. Hydraulic sections add pressure-measuring-point diagrams, pump test forms, and control-valve disassembly details.

Working on high-pressure hydraulics and heavy machinery carries inherent risks. Follow the manual's safety precautions for pressure release, lifting, and supporting assemblies.

Controls, Schematics, and Fault-Code Coverage

A008 Variotronic Ti menus display transmission adjustment, high-pressure readings, and discharge temperature. They support diagnosis but do not replace the documented pressure measurements and electrical tests.

Separate Auto-Guide steering-angle procedures cover EOL versions up to 7.58 and from 7.60 onward. Transmission-ratio calibration includes its own error-message explanations, while FENDIAS Vendi documentation covers valve diagnostics.

Diagram examples include the transmission function schematic, hydraulic PTO control drawing, and EPC 23-OBE sectional view and circuit diagram. CAN control-bus wiring, Auto-Guide power-and-steering hydraulic plans, and EPC-OBE troubleshooting flowcharts support electrical and hydraulic fault tracing.

The additional fault-code publication covers specified 300, 400, and 900 Vario models, earlier COM I/II tractors, and the 820 greentec as well as the main COM III models. This broader coverage is for fault-code interpretation, not additional workshop repair manuals.

A Selection of Valve and Fluid Specifications

These examples show a small part of the adjustment and fluid data in the workshop manual.

For the TCD 2012L06-4V engines in the listed models, cold valve clearances are 0.4 mm at the intake and 0.5 mm at the exhaust.

The fluid tables give approximate maximum fills of 13.5 L for engine oil with a filter change and 50.0 L for the hydraulic system. They also direct readers to the operator's manual matching the chassis number for applicable filling quantities.

Search, Bookmarks, and PDF Contents

Navigation and drawing detail: Text search and embedded bookmarks cover both publications, although some tables and diagram labels are embedded as graphics. Small labels in dense wiring and hydraulic drawings require zooming; watermarks cross some illustrations.

The set is supplied as one printable PDF with 1,459 pages:

These counts already include the workshop manual's five opening pages and the fault-code publication's cover, notice page, and four section dividers.
