Restore your ASV RC-85 Rubber Track Loader to full operation with this 153-page factory reference (OEM #ASVSP004). Bundling six separate documents for the RC-85 and RC-100 into a single searchable file, it delivers exact specifications for every repair. Trace pressure lines and solenoid valves using the complete hydraulic schematic, or track down parasitic draws with the full electrical diagram. The guide details hydrostatic and auxiliary pump disassembly, undercarriage maintenance, and radiator assembly. It also provides exact torque values, such as 125 ft-lb dry for the bogie wheel retaining nut, 160 ft-lb dry for drive motor mounting bolts, and 85 ft-lb with Blue Loctite for transmission mounts. Download the file directly to your tablet and bring it straight to the job site.

ASV RC-85 Common Problems This Manual Covers
ASV RC-85 drive controls slow to respond, joystick inputs delayed, tracks hesitate before moving p. 59
Check the troubleshooting chart on page 59. Verify the lap bar is fully lowered and the operator presence switch is closed. Test charge pump pressure at the diagnostic port; it must read 400-450 psi. If pressure is within spec, inspect the DA Control Solenoid and pilot control circuit for a sticking or failed solenoid.
Manual Section: Lift arms operate but tracks will not moveEngine won't crank under its own power, only starts with a jump box connected p. 59
Check the troubleshooting chart on page 59. Inspect battery terminals for corrosion and verify all ground straps are tight. Test the main power fuse and ignition switch circuit against the electrical schematic on page 153. The fuel gauge draws only 0.01 amps in the off position; a parasitic draw above that level points to a relay or wiring fault.
Manual Section: Machine will not crank overRubber tracks worn, cracked, or sagging low with noticeable sag between bogies p. 81
Apply 90 lbs. of weight at track mid-span and measure deflection. Correct range is 0.75-1 inch (page 81). Adjust idler tension if out of spec before condemning the track. When reinstalling, torque drive sprocket lug nuts to 160 ft-lb dry and bogie wheel retaining nuts to 125 ft-lb dry; both specs are on page 9.
Manual Section: Track TensionEngine starts and runs normally but lift arms and track movement won't respond p. 59
Verify the lap bar is fully seated and the operator presence switch is functioning; both must close before hydraulic power enables. Check charge pressure at the test port; it must reach 400-450 psi. If pressure is low, inspect the safety relay, safety solenoid, and operator presence circuit using the diagnostic sequence on page 59.
Manual Section: Machine starts but hydraulics will not operateHydraulic system running hot during work cycles, hot oil warning light illuminates p. 59
Inspect the oil cooler and A/C condenser for debris or mud packing. Check fluid level, then verify the cooler bypass relief valve opens at 80 psi (689 kPa) per specs on page 9. Inspect fan blades for cracks and confirm belt tension is snug. If all cooling components check out, follow the hot oil diagnostic tree on page 59.

What are the torque specs for ASV RC-85 track loader?
The ASV RC-85 track loader has critical torque specifications for several components. These include Transmission Mounting Bolts at 85 ft-lb. with Blue Loctite, Drive Sprocket Drive Teeth Bolts at 105 ft-lb. (Dry), Bogie Wheel Retaining Nut at 125 ft-lb. (Dry), Drive Sprocket Lug Nut at 160 ft-lb. (Dry), and Drive Motor Mounting Bolts at 160 ft-lbs. (Dry).
How to troubleshoot ASV RC-85 won't start?
If the ASV RC-85 machine will not crank over, probable causes include a continuous high or low flow switch activated, power quick-attach in the unlocked position, a weak or dead battery, or issues with the ignition fuse, starter, or wiring connections. If the machine cranks but will not start, check for a blown injection pump fuse, main power fuse B, or issues with the glow plugs or their connections.
How to fix ASV RC-85 drive control issues?
If the ASV RC-85 lift arms operate but the tracks will not move, probable causes include a leak in the feed line to the pilot control, a bad wire connection to the DA Control Solenoid, or a malfunctioning pilot control. Another potential issue is low charge pressure.

Document Quality
This PDF is a collection of scanned documents, not a native digital PDF. An OCR layer has been applied, so you can search the full text and copy content from all pages. Text is generally crisp and readable throughout, though some sections appear to be from slightly lower resolution scans. All diagrams and illustrations are raster images, meaning they will pixelate when you zoom in extensively, but labels are readable at typical viewing magnifications. The pages are clean with no noticeable scan artifacts, stains, marks, or skewed pages, and there are no notable blank or filler pages.
