Market Position:
Essential technical documentation for owners and mechanics of the popular Fordson Dexta tractor, enabling effective maintenance and repair.
Key Features:
Detailed illustrations, exploded diagrams, step-by-step instructions, special tool references, troubleshooting guides, and factory specifications.
Special Tool References:
Manual explicitly references the use of specific Fordson special service tools (SSTs) and provides their part numbers where applicable, ensuring correct repair procedures.
Pictorial Diagrams:
Extensive use of pictorial diagrams, including exploded views, to illustrate component relationships and assembly order.
Competitive Analysis:

Technical Depth:
Comprehensive, step-by-step procedures from basic adjustments to major overhauls, suitable for both professional mechanics and DIY enthusiasts.
Diagnostic Procedures:
Includes specific diagnostic flowcharts and testing procedures for electrical, hydraulic, and fuel systems to identify faults accurately.
Engine Oil Change Interval:
Typically every 100 hours or annually (refer to manual for specific interval).
Transmission Oil Change Interval:
Typically every 1200 hours or annually (refer to manual).
Hydraulic Oil Change Interval:
Typically every 1200 hours or annually (refer to manual).
Engine Oil Type:
API CD or CE rated diesel engine oil, viscosity usually 15W-40 or 20W-50 depending on climate (refer to manual).
Hydraulic Fluid Type:
Ford 300 series universal tractor transmission oil (UTTO) or equivalent.
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors, mixed with distilled water (typically 50/50 ratio).
Brake Fluid Type:
Not applicable (typically dry drum brakes requiring lubrication, not hydraulic fluid).
Transmission Hydraulic Fluid Capacity:
Approximately 12-14 Imperial gallons (54-64 Liters) for the combined transmission, hydraulics, and rear axle sump (refer to manual for exact capacity).
Common Issues:
Wear in transmission synchronizers (if equipped with certain variants), hydraulic lift system leaks, potential for injector pump calibration drift, starter motor wear.
Common Issues Detail:
Perkins AD3.152 engines are generally robust but can suffer from injector pump wear, issues with the glow plug system if fitted, and potential head gasket failure if overheated. PTO engagement mechanisms can become stiff or worn. Hydraulic lift may lose pressure due to worn pump seals or cylinder seals.
Common Issues Maintenance:
Regular greasing of kingpins, tie rod ends, and universal joints is critical. Water contamination in fuel or hydraulic systems can lead to significant damage.
