Rosco RA-2000 2001 Parts Catalog – OEM Factory Specs

If you’ve ever ordered the wrong aggregate metering arm for a Rosco RA-2000 because you trusted a photo-copied aftermarket catalog, you know the pain. You pull the old part, the new one doesn’t line up, and the machine sits dead while the customer watches. The Rosco RA-2000 2001 Parts Catalog – 149 pages of the same documentation a LeeBoy factory tech uses – eliminates that guesswork. No third-party reinterpretations. No “close enough” dimensions. This is the OEM file, part number 38022-02, effective from serial number 37360 and up.

Safety Section: Why You Read Page 1.1 Before Touching a Wrench

Seven pages of the safety section cover fire and explosion prevention, battery handling, and hot material safety. The RA-2000 carries liquid asphalt at 300°F. If you pull a hose clamp without knowing the lockout procedure, you get a burn that takes months to heal. Page 1.8 spells out the electric heater safety steps. The sign-off form on page 1.12 is a daily checklist – I make my junior techs initial it before they start any hydraulic work. That’s the difference between a job site lawsuit and a routine repair.

Bolt Torque Chart on Page 5.17

Five-seventeen gives you inch‑pound and foot‑pound values for every fastener on the patching system. Axle nuts, engine mount bolts, aggregate door hinge pins – they’re all listed. Last month a shop in Laredo called me because their RA-2000 was leaking emulsion from the kettle flange. The torque spec for the flange bolts was 45 ft‑lb, but the guy had used 60. Warped the gasket. That chart would’ve saved him an afternoon of rework. OEM specs are non‑negotiable on this equipment.

Rosco RA-2000 2001 Parts Catalog: What You Get in the File

You’re not buying a PDF of some guy’s scanned highlights. This is the unmarked, factory‑released document. Inside you get the full Table of Contents: Introduction, Serial Number Location (page 0.3 – find the tag on the left frame rail), Warranty details, and a seven‑page Material Section that tells you exactly how to select aggregate and handle liquid asphalt. The Operation Section runs from page 4.1 to 4.15 and covers the theory of operation, truck hitch preparation, pre‑start checks, and asphalt heating. The Maintenance Section goes to page 5.17 with a preventive maintenance chart and that torque table. Then you hit the Trouble Shooting Section starting on page 6.1 – eleven possible faults with diagnostic flowcharts. Finally, Section 7 is the Parts Catalog itself, exploded views with callouts and OEM part numbers.

Troubleshooting Section: When the Patcher Won’t Heat

Page 6.3 covers the most common complaint I get: burner won’t light. The manual walks you through checking the fuel solenoid, igniter gap, and air pressure switch in order. Follow that sequence and you’ll find the fault in under 20 minutes. Skip it and you end up replacing a control board that was fine. I’ve seen it happen. The guide also lists material heating issues – cold spots in the kettle, temperature sensor drift. Each symptom has a cause and a fix.

3 Reasons to Use OEM Documentation Over Aftermarket Copies

First, aftermarket sellers often crop the safety pages to save paper – you lose the decal placement diagrams on pages 2.1 through 2.6. Second, torque values get rounded to “standard” numbers that don’t match the fastener grade. Third, part numbers change when Rosco supersedes a component; the OEM catalog includes the supersession notes in the Parts Catalog section. Don’t rely on a generic binder from a parts house. This is the original file, exactly what a LeeBoy dealer would hand you.

If you work on asphalt patching equipment, you’ve probably seen a beat‑up paper copy of this catalog in some old mechanic’s toolbox. That copy is missing pages. This digital version is complete and searchable – you can CTRL+F “kettle” and find every mention in seconds. The file is 149 pages, published in 2001, and covers the RA-2000 from serial 37360 onward. I keep a copy on my tablet under the workbench in San Antonio. It’s the only parts book I trust for this machine.

Does this manual cover the RA-2000 with serial numbers below 37360?

No. The catalog is effective for serial number 37360 and higher. Earlier machines used different part numbers. Check your serial plate before ordering.

How do I find the bolt torque for the kettle door hinge?

Page 5.17 lists all fastener torques. The door hinge bolts are 3/8‑16 grade 5 – torque to 30 ft‑lb. That’s the factory spec.

Are the wiring diagrams included?

This is a parts catalog, not a service manual. It contains exploded views with part callouts but not full wiring schematics. For electrical troubleshooting you want the separate Operation/Maintenance/Service manual for the RA-2000.

Can I print this PDF and put it in a binder?

Yes. The file is not copy‑protected. Print it, laminate the safety decal pages, and throw it in the toolbox. That’s what I did.

Ordering parts for a Rosco patcher without this catalog is like torquing head bolts by feel. You might get lucky, but you’re betting the job. Download the Factory Manual now and get the correct OEM part numbers, torque specs, and safety information direct from the manufacturer.
