Atlas Copco ATLASIIO4 Parts Catalog – OEM Factory Spare Parts List

Over the years I’ve seen more botched repairs from wrong parts than from wrong torque specs. You order a seal kit off some generic website, it shows up, and the bore is off by half a millimeter. Then the machine leaks hydraulic oil all over a customer’s driveway. That’s why Atlas Copco ATLASIIO4 Parts Catalog belongs on your bench, not some third-party reprint. 172 pages of factory-sourced part numbers, symbols for wear items, and the exact order instructions that Atlas Copco engineers wrote. No guesswork.

172 Pages of Factory Part Numbers

Flip through this catalog and you’ll see every component broken down by illustration and order number. The manual covers the ATLASIIO4 up to serial number 114M 31972. Each page lists the exact part number, a symbol code (D for packing set, V for wear part, R for repair set, M for material length, NB for as required), and a note if the part cannot be supplied individually. That last bit saves you from ordering a single bolt that only comes in a full assembly. You want the rear screen? Page 2 shows Order-No. L358467. Don’t waste time cross-referencing aftermarket catalogs that might have a similar number. Use the factory list.

How to Use the Spare Parts List Correctly

Don’t just open the catalog and start pointing. Atlas Copco includes a specific ordering example on page 2. You must indicate the machine’s serial number when ordering any part. The example shows a figure number (050.038.02.0) and a position number for the rear screen. If you skip the serial number, the supplier cannot guarantee the part matches your machine. Also note that parts without an order number cannot be supplied as individual components. That means you may need to buy a sub-assembly instead of a single gasket. Read the symbol table before you order.

Symbol Codes: D, V, R, M, NB Explained

Each part in this catalog gets a one-letter code. D means packing set or packing part — these are the seals and gaskets you’ll replace during a rebuild. V is a wear part: bushings, cutting edges, filters. R is a repair set: a kit of parts for a specific overhaul. M indicates material sold by length — hoses, wire, trim. NB means “as required” — no fixed quantity; order what you need. Memorize these codes and you’ll stop ordering wear parts when you needed a packing set. This catalog spells it all out in three languages (English, German, French) on page 2.

Does This Catalog Cover Your Serial Number Range?

Check the first page: “BIS FABR.NR. UP TO SERIAL NO. JUSQU’AU NO. DE FABR. 114M 31972.” If your ATLASIIO4 has a serial number lower than that, you’re covered. If it’s higher, Atlas Copco may have made running changes not captured in this edition. The manual itself warns that the machine may have improvements not reflected at printing time. Always double-check the serial number before ordering. The Automotive Industry Overview gives context on how manufacturers update parts, but the catalog itself is your final authority on what fits your specific unit.

Aftermarket Catalogs vs. This OEM Print

I’ve had techs bring me a printout from some online parts database and swear it matches. Then we pull the OEM catalog and the order number is different. Aftermarket sources often transpose digits or use supersessions without notation. This catalog is a direct scan of the original Atlas Copco spare parts list — the one used by dealerships. The PDF includes the factory warning that claims cannot be derived from its content for constructive purposes, which is standard legal language, but the part numbers are accurate as of the print date (04.90). For critical repairs, use the factory document.

If you’re working in a home garage or a small shop, you don’t have a dealer hotline. You have this PDF. The Automotive Industry Overview can tell you about the industry, but only this catalog tells you the exact order number for your ATLASIIO4’s left-hand side excavator components. The manual even explains how to determine left vs. right: looking from the cabin in the driving direction, with the steering axle forward. That level of detail is absent from generic parts lists.

Can I use this catalog for a different Atlas Copco model?

No. This catalog is specific to the ATLASIIO4 with serial numbers up to 114M 31972. Different models have different part numbers.

How do I determine left and right sides for excavator parts?

The manual states that “spare parts for the LH excavator side L or the RH excavator side R are determined looking from the cabin into driving direction. The steering axle has to be in travelling position, to the front.” That means you sit in the cab, face forward, and left is your left. If you’re ordering a left-hand final drive seal and you’re standing outside the machine facing the bucket, you might order the wrong side. Follow the factory procedure exactly. Reference the diagram on page 3 if available.

Stop wasting time with aftermarket parts books that send you the wrong bushings. Access the Factory Manual and get the exact order numbers and symbols you need to keep that ATLASIIO4 running.
