2000 ASV POSI-TRACK 4810 Track Loader Operator, Service & Parts Manual Set (P/N 0310-657, 0310-658)

Use the service procedures to plan undercarriage work and investigate drive problems, then match the illustrated assembly references to the parts lists when identifying replacement components.

Engine coverage centers on Caterpillar 3054T maintenance rather than internal engine overhaul. Injection-nozzle bleeding is referred to a separate Caterpillar Operation and Maintenance Manual.

Text Search, Bookmarks and Drawing Detail

Search and schematic readability: Written sections, parts lists and schematic labels support text search, but callout numbers in some exploded drawings do not. Bookmarks open both manuals and both schematics. Small electrical labels require substantial zoom; several rollcage wire IDs contain question marks in the original drawing.

One printable PDF contains 116 pages: the publications and schematic sheets listed above, plus one introductory page. Both manual covers, two service-log pages and three notes pages are already included in the publication page counts.

Track Service, Drive Diagnosis and Illustrated Components

The selected topics below are supplemented by loader grease-point illustrations and a service-items cross-reference linking Caterpillar numbers to ASV part numbers.

• Track and undercarriage repair: Step-by-step instructions for removing and installing tracks, collapsing and tensioning the suspension, and removing bogie carriages, wheel tubes, end tubes and drive sprockets.

• Engine maintenance: Caterpillar 3054T oil and filter service, fuel-filter replacement, fuel-system priming, air-cleaner maintenance, and radiator and oil cooler cleaning.

• Hydrostatic drive: Operating principles, drive-pump relief information, charge-pressure testing, hydraulic oil and filter service, and troubleshooting for weak, sluggish or unresponsive tracks.

• Loader operation: Drive and attachment controls, auxiliary hydraulics, capacity guidance, loader lockout pins, bucket operation and side-slope precautions.

• Parts identification: Exploded views, reference numbers, ASV part numbers and quantities for chassis, powertrain, hydraulic, suspension and operator-station assemblies.

• Circuit references: Electrical and hydraulic schematics with harness connections, connector pin numbers, wire identification, fuse references and power-distribution circuits.

ASV addresses operators and service personnel responsible for vehicle operation and normal maintenance; the service procedures also call for lifting equipment and a pressure gauge.

Undercarriage Service and Planetary Drives

Track instructions illustrate the sliding planetary mount and hinged carrier wheels, with separate guidance for the onboard screw jack and a remote hydraulic jack. Dedicated Posi-Track jack stands are identified as P/N 454-876.

The track-service cautions explain how excessive tension can damage bearings and tracks, while sprocket misalignment can cause derailment.

Planetary maintenance includes break-in checks and lubricant replacement using the fitting-and-hose drain kit. The service coverage does not extend to internal gearbox overhaul.

Fuel-System Maintenance and Cooling Access

Fuel priming instructions cover the filter vent and injection-pump inlet. Air-cleaner guidance distinguishes the serviceable primary element from the non-washable secondary element.

The swing-out radiator and oil cooler provide access for cleaning. Safety guidance addresses the exposed cooling fan and the need for loader lockout pins when servicing beneath a raised loader.

Hydrostatic Fault Isolation

The drive discussion relates Sundstrand tandem pumps, Eaton track motors and relief-valve behavior to machine response. Charge-pressure testing helps narrow down erratic track response, while the problem/cause/remedy charts distinguish pressure faults from interlock, linkage, filter and oil-temperature problems.

Assembly Breakdowns for Parts Selection

Seat-base, rollcage, steering-console and transmission-linkage views identify associated hardware and controls. Suspension illustrations separate torsion axles, wheel tubes, and left- and right-hand drive assemblies.

Hydraulic breakdowns distinguish the high-flow valve, neutral lock and charge relief, transmission and gear pumps, and reservoir plumbing. Loader and quick-attach drawings identify cylinders, pins, hoses and latch components.

The 3054 DIT Engine Assembly breakdown shows the installed engine’s mounts, external connections, drive coupling and harness. It is not an internal Caterpillar engine parts catalog.

Electrical Harnesses and Hydraulic Circuits

The 4810 Electrical Schematic connects the seat, reservoir, main-console, engine and rollcage harnesses to the power-distribution circuits. Pin numbers, wire colors and circuit descriptions support connection tracing alongside the fuse chart.

The 4810 HYD Schematic links the transmission and drive motors with the auxiliary pumps, directional valves, filters, cooler and brake cylinder.

A Preview of Charge Pressure and Planetary Break-In Data

At engine idle with warm hydraulic oil, the charge-pressure check specifies 280–320 psi. Planetary drive sprocket lug nuts have a 115 ft-lb specification, with retorque scheduled after the first 10 operating hours.

The initial planetary oil change is due at 50 hours. The break-in notes explain how the high metal content of the initial oil fill can shorten gearbox life if that change is missed.
