New Holland E805 Tier 3 Crawler Excavator Repair Manual

This crawler excavator travels on tracks and uses hydraulic equipment to operate its digging attachment and rotating upper structure. The service material treats the undercarriage, drive mechanisms and upper body as distinct working areas.

Illustrations identify fuses and relays, show gear assemblies and explain work on the rollers supporting the tracks. Hydraulic procedures address pressure release, system cleaning and settings before component service. The numbered organization makes it possible to follow an electrical, track or hydraulic repair within its own section while referring to the related assembly drawings.

What’s Covered Inside

• General information and service data: Safety information, machine specifications and fastener-tightening references.
• Engine installation and fuel system: Engine removal and refitting, radiator work and fuel-tank service rather than an assumed internal-engine overhaul volume.
• Electrical equipment: Circuit troubleshooting, battery checks, fuses, relays and electronic control boxes.
• Tracks and drive assemblies: Rollers, guide wheels, tensioners, travel motors and the gears used for travel and upper-body rotation.
• Hydraulic testing and component service: Pressure checks and work on pumps, control valves and cylinders that extend or retract to move the attachment.
• Upper structure and operator area: Rotating base, counterweight, digging equipment, seat, cab and air-conditioning components.

The section references provide a practical route into track-roller service, hydraulic pressure testing or electrical fault investigation. Electrical procedures use the 4001–4003 references and track work appears in the 5000 series; these identify service sections rather than page totals.
