ASV POSI-TRACK 2800 & 2810 Track Loader Operator, Service & Parts Manual Set (P/N 0308-382, 0308-383)

The operating and service instructions explain the work, while the parts drawings identify the assemblies and hardware involved. The additional schematics provide larger electrical and hydraulic circuit references.

Service coverage focuses on normal maintenance, undercarriage repair and troubleshooting. Some engine conditions are referred to a separate engine manual, and certain hydraulic pressure faults require dealer service.

PDF Search, Bookmarks and Diagram Detail

Finding text and reading circuits: Text search works across the main written sections and parts lists, but several diagnostic charts and drawings lack searchable labels. Embedded bookmarks lead to the two manuals and supplementary schematics. Small wiring labels require zooming; some labels in the parts-manual schematics remain soft when enlarged, while the supplementary electrical sheet provides clearer detail.

Supplied as one printable, 128-page PDF in English. The total includes the publications listed above and one additional introductory page.

Track Service, Machine Operation and Parts Reference

This overview covers selected service topics. The manuals also include battery-care guidance and illustrated windscreen assembly references.

• Track and undercarriage repair: Step-by-step procedures for track removal and installation, bogie carriage removal, wheel tube removal, wheel replacement, end tube removal and drive sprocket removal.

• Engine and fuel service: Engine oil and filter changes, fuel-filter replacement, fuel-system bleeding and the 2800-specific fuel pre-screen.

• Hydraulic maintenance: Reservoir oil and filter service, filter-manifold arrangements, auxiliary circuit connections and hydraulic flow reference charts.

• Operation and attachments: Hydrostatic drive controls, loader lockouts, quick-attach and frame mounts, reversible seating, and ROPS/FOPS protection information.

• Fault diagnosis: Problem/cause/remedy tables and electrical troubleshooting charts for starting, shutdown, loader operation and track response.

• Parts identification: Illustrated assembly drawings with reference numbers, quantities and ASV part numbers for drivetrain, suspension, hydraulic and loader components.

Written for operators and service personnel, the operator/service manual addresses safe operation and normal maintenance; its undercarriage procedures also call for lifting and supporting equipment.

Undercarriage Work and Drive Alignment

Photographic instructions connect track removal and installation with tension and sprocket-alignment checks. This gives mechanics a reference for maintaining drivetrain integrity and planning access to bogie carriages, wheels and end tubes.

The parts manual adds separate left- and right-side drive and undercarriage assemblies, suspension axles, and axle assemblies 0307-927, 0307-929 and 0307-931. Transmission linkage appears as an illustrated parts assembly rather than an internal transmission overhaul procedure.

The track-tension section warns that overtightening can cause bearing failure and track damage. Its alignment notes also explain how mismatched adjustment positions can leave the sprocket misaligned and cause derailment.

Dedicated support equipment is identified for track work: POSI-TRACK jack stands, PN 454-876, and a remote hydraulic jack with extensions, PN 455-3445.

Fuel, Filtration and Cooling Service

Fuel-system bleeding instructions distinguish the primer arrangements on the two models. Fuel-filter coverage also identifies the 2800-only pre-screen, helping separate a model-specific fuel restriction from broader starting or power complaints.

Hydraulic service distinguishes disposable spin-on filters from a canister with a replaceable internal element. Engine parts drawings separately show turbo and naturally aspirated assemblies.

Radiator and oil-cooler maintenance explains the pusher-fan airflow and access through the louvered grille. The parts drawings identify the adjacent coolers and chassis heat exchangers.

Troubleshooting and Circuit References

Pre-start checks and troubleshooting tables address no-start conditions, weak attachments, sluggish tracks, derailment and overheating. Electrical charts follow starting and interlock circuits through switches, relays and solenoids.

References include the High & Low Flow Auxiliary Hydraulic Circuit chart and schematics for the Isuzu engine, relay panel, roll cage and filter manifold, plus the hydraulic schematic. Console drawings show harness connections and fuse-panel circuits.

Servicing high-pressure hydraulic circuits and heavy undercarriages presents serious physical hazards. Work involving raised loader arms requires the manual’s lockout precautions and suitable vehicle support.

Preview of Planetary Drive Service Specifications

The planetary drive sprocket’s mounting lug nuts are specified at 115 ft-lb, with a torque recheck after 10 operating hours.

Planetary gearbox oil has a 50-hour break-in change, followed by changes every 1,000 hours or annually, whichever comes first. Track-tension guidance specifies no sag between the drive sprocket and top carrier wheels, alongside a warning against overtightening.
