• Provides factory-authorized specifications and maintenance intervals for liquid-cooled engine and transmission systems
• Comprehensive sub-system coverage including liquid-cooled engines, electrical networks, power train assemblies, hydraulic components, steering mechanisms, brake systems, attachment interfaces, and miscellaneous chassis hardware
• Contains essential shop references like wiring diagrams, component location drawings, hydraulic schematics, tolerance charts, diagnostic flow charts, testing charts, and exploded-view diagrams

What the Manual Documents

Working on the Select or Ultimate Series requires precise data. This PDF technical reference delivers an expert-level breakdown of all primary machine systems, directly improving shop floor efficiency by structuring data according to operational groups. You get a complete look at the liquid-cooled engine, electrical architecture, power train, and hydraulics. It also outlines the steering and braking components in detail, alongside dedicated sections for attachments and miscellaneous service tasks.

The document organizes information logically by system. It shows exact component locations, explains the theory of operation, and maps out the diagnostic testing procedures necessary for accurate troubleshooting. When chasing an electrical issue, the manual provides comprehensive wiring diagrams and circuit schematics to help track it down. It includes step-by-step repair instructions for complex tasks like hydrostatic transmission rebuilds, steering valve overhauls, and hydraulic pressure adjustments—procedures that typically require a specialized facility. You will also find specific diagnostic and repair data for the FD671D and FD750D engines, alongside supplementary data covering fastener and seal specifications to ensure assembly torque and tolerance values match original factory standards.

Because servicing heavy equipment involves high-pressure hydraulics and moving drivetrain parts, these procedures present serious shop hazards. Always verify safety protocols and consult a certified technician before starting active teardowns.

Specification Highlights

Having the right numbers on hand speeds up any maintenance routine. This publication is packed with detailed tolerance charts, exact fluid capacities, and electrical reference values tailored for the shop floor.

For example, cylinder compression must hit a 620 kPa (90 psi) minimum on a warm engine. Engine oil pressure is clearly specified at a 276 kPa (40 psi) minimum while running at 1250 rpm. You will also find cooling system capacities explicitly documented—these specific models take exactly 4.0 liters (4.2 quarts). It provides the hard factual data technicians need to evaluate system health and complete complex diagnostics safely.
