Comprehensive Landini 60 Series Evolution Training Manual for 5860, 6860, 7860, and 8860 Tractors (2002)

Landini 60 Series Evolution Training Manual - 2002 Edition

This technical training publication provides the structural framework for the maintenance and repair of the Landini 60 Series Evolution tractor line. It contains specific diagnostic procedures, mechanical tolerances, and hydraulic flow benchmarks essential for maximizing machine lifecycle and ensuring peak field performance. Utilizing genuine Landini lubricants, such as those meeting the specified 33-liter transmission oil capacity, is critical for maintaining the integrity of the synchronized gearsets and preventing premature component failure.

Technical Applicability & Machine Configurations

The documentation is segmented by chassis requirements and engine architecture to provide precise service guidance for the following configurations:

Landini 60 Series Evolution (Perkins Natural Aspiration)

• Model 5860: 3-cylinder Perkins 903-27 engine; 2.7L displacement.
• Model 6860: 4-cylinder Perkins 1004.40 engine; 3.99L displacement.
• Model 7860: 4-cylinder Perkins 4.41 engine; 4.1L displacement.

Landini 60 Series Evolution (Turbocharged Variants)

• Model 8860: 4-cylinder Perkins 4.41 Turbo; 4.1L displacement.
• Model 8860 E: 4-cylinder Perkins 1004-42 Turbo; 4.233L displacement.

Landini Atlantis Series (Specialty Configurations)

• Atlantis 75: High-clearance and specialized chassis variants.
• Atlantis 85: Enhanced power output configurations with specific hydraulic flow rates.

Operational Parameters & Service ROI

• System Integrity: Detailed calibration for the 180-bar high-pressure hydraulic circuit ensures consistent lifting capacity (up to 3700 kg with auxiliary cylinders) and implement control.
• Powertrain Reliability: Verification of the 9/44 Gleason bevel gear pair setup and differential lock engagement sequences prevents drivetrain shock loading.
• Safety Compliance: Mandatory inspection of the Roll-Over Protective Structure (ROPS) and safety decals ensures operator protection and legal operating status.
• Electrical Precision: Full mapping of the 12V negative-ground system, including the 55A alternator and front/main fuse box assignments, reduces diagnostic downtime.

Technical Depth & Factory Benchmarks

The manual defines critical factory settings required to restore the machine to original operational standards:

• Engine Calibration: Tappet clearances must be maintained at 0.20 mm (Intake) and 0.45 mm (Exhaust) for cold engines to ensure thermal efficiency.
• Injection Timing: Static timing for Perkins 903.27 and 1004 series engines requires alignment of timing marks (A) on the drive shaft, camshaft, and injection pump gears at Top Dead Center (TDC).
• Hydraulic Relief Settings: The main calibration valve for the mechanical power lift is set at 170 bar, with the antishock safety valve calibrated to 190 bar.
• Clutch Coplanarity: Lever heights for the Lx (Ox) twin-plate clutch must be checked for coplanarity using the 01 FRI REX special tool.

Visual Navigation Aids

• Power Train Schematics: Section 4-2 provides logic flow for the basic gearbox + reverse shuttle, including creeper and overdrive options.
• Braking Circuitry: Diagrams for both 2WD and 4WD configurations illustrate the link between the hydraulic reservoir and the synchronized front/rear brake transducers.
• Wiring Integration: Functional diagrams for both Standard and NAO versions detail terminal boxes X1 (Rear), X2 (Front), and X5 (Trailer).

Operational Limits & Specifications

• Torque Sequence: Cylinder head fixing screws (M12/M14) require a primary torque of 110 Nm followed by angular tightening (150° for short, 180° for medium, 210° for long screws).
• Fluid Capacities: Transmission and hydraulic reservoir require 33 liters of high-specification oil; front brake reservoirs must utilize vegetable-type brake fluid only.
• Mechanical Clearances: The minimum tolerated synchro-ring X-dimension in the transmission is 1.25 mm for the engine-gearbox axle and 0.5 mm within the gearbox housing.
• Fastener Standards: Standard M8 intake/exhaust manifold nuts require a driving torque of 22 Nm (2.2 kgfm).
