Deutz-Fahr Agrotron MK3 Series 2001–2003 Tractor Workshop Manual (P/N 307.1079.3.6)

This 696-page factory workshop manual PDF covers the Deutz-Fahr Agrotron 106 MK3, 110 MK3, 115 MK3, 120 MK3, 135 MK3, 150 MK3, and 165 MK3. The January 2002 English publication is identified by manufacturer code 307.1079.3.6. Written for repair technicians, with the technical material designated for Authorized Dealers and Service Centers, it is best suited to trained personnel who have the required diagnostic software, pressure-test equipment, lifting gear, and special tools.

• Power Shift and Power Shuttle systems are treated separately, including clutch and solenoid-valve operation, gearbox and shuttle control valves, pressure-test points, electronic controls, the rear axle, and two- and four-speed rear PTO arrangements.
• Separate CC/CCLS and LS hydraulic sections distinguish fixed- and variable-displacement systems, as well as the different pump layouts used on the 106-115 CV and 120-165 CV model groups. Coverage extends to priority and load-sensing valves, auxiliary control valves, steering, rear lift, and hydraulic front suspension.
• Workshop procedures include brake-system bleeding, power-steering testing and seal renewal, pump testing and replacement, auxiliary valve-block and lift-cylinder service, front-suspension cylinder repair, sensor positioning, and brake, clutch-pedal, parking-brake, and lift adjustments.
• SERDIA Level III and EDS diagnostics cover DEUTZ EMR, EMS, and MVS engine ECUs; DEST 38 Power Shift and DEST 45 Power Shuttle diagnosis; T-7100, T-7200, and T-7300 transmission sensor and solenoid checks; AGROTRONIC-HD/ASM, Infocenter, and suspended-front-axle fault finding.
• Major removal and installation work includes air-conditioning recovery, flushing, and recharge; cooling-package service; front lift and front PTO removal; suspended front-axle removal; cab removal; and engine-to-transmission separation and reconnection. Model-specific procedures distinguish the 165 CV cooling and air-conditioning layout from the 106-150 CV tractors.
• For electrical repair, the manual supplies component, code, and connector indexes; connector-face layouts; component test data; ECU pinouts; system schematics; wiring-harness plans; and on-machine connector-location views.

Diagnostic and visual references

The diagnostic chapters go well beyond code lists. They cover ECU identification, live measured values, input/output assignments, CAN status, error memory, actuator function tests, parameter handling, accelerator and hand-throttle calibration, transmission end-of-line programming, Power Shuttle main-clutch contact-pressure calibration, lift-valve calibration, Infocenter testing, and front-suspension sensor calibration.

Named visual references include Power Shift and Power Shuttle clutch-engagement and solenoid-valve schematics, CCLS/LS hydraulic-system diagrams, separate engine wiring for the 106-115 CV and 120-165 CV groups, transmission wiring, hydraulic and air trailer-brake wiring, and control-unit/fuse/relay diagrams with connector locations. Exploded and sectional views identify the gearbox controls, rear axle, rear PTO, brakes, hydraulic pumps, front axle, and auxiliary control valves.

Specifications, tools, and repair cautions

Reference material includes standard and component-specific torque data, approved threadlockers and sealants, hydraulic pressure-test specifications, pump and valve data, sensor voltage and resistance checks, adjustment values, and calibration data. The special-tool list identifies T1-T4 steering-unit seal tools 00239496 through 00239499, T5/T6 sensor test leads 5.9030.743.1 and 5.9030.743.0, plus the T7-T10 SERDIA/EDS installation media, adapter, Level III interface, and software pack.

The front-suspension position-sensor section includes the positioning check needed to prevent impact damage at the end of sensor travel. During power-steering seal repair, the manual also warns against over-clamping the housing or damaging the seal seats and specifies the dedicated seal tools and correct indexed assembly details.

Important scope limit

This publication expressly does not contain full internal engine or transmission repair sections. It directs technicians to separate English manuals for the DEUTZ 1012/1013 engine (0297 9771), ZF 7100L and 7100S transmissions (0298 6838 and 0298 6872), 7100 rear axle (0298 6878), 7200 L-S-H transmission/rear axle (0298 6832), and ZF 2025/2035/2045 AS front axle (0298 6856). This PDF does include tractor-level system descriptions, diagnostics, external component repair, wiring, and the specified removal, adjustment, and separation procedures.

Repairs involve stored hydraulic and air pressure, refrigerant handling, and heavy component lifting. Follow the manual's isolation, pressure-release, recovery, support, and lifting requirements, and use trained personnel for work requiring dealer diagnostic equipment or specialized tooling.
