Dynapac CC522C 2004 Parts Catalog

If you’ve ever ordered a hydraulic motor seal ring only to find it’s the wrong diameter when the machine is already torn down, you know the pain I’m talking about. That’s what this Dynapac CC522C 2004 Parts Catalog is built to stop. 265 pages of factory-issued part numbers, exploded diagrams, and ordering instructions directly from Dynapac Sweden. No aftermarket guesswork, no third-party re-interpretations.

Every roller serial number range is accounted for. The catalog covers the CC522C vibratory combination roller equipped with the Cummins 4B 3.9 TAA diesel. You’ll find the exact part numbers for engine components, vibration system, hydraulic pump and motor groups, steering, roll frame, and electrical harnesses. Page 4 lays out the six pieces of information you need when ordering spare parts: machine type, roller serial number, quantity, part number, denomination, and dimensions for bulk items. Miss any one of those and you’re looking at a return shipment.

Engine Group (Cummins 4B 3.9 TAA)

The engine section breaks down the Cummins 4B 3.9 TAA into subgroups: cylinder head, fuel system, lubrication, cooling, and air intake. Each part is listed with its Dynapac part number, description, and quantity per assembly. If you need a new injector or a gasket set, the number in this catalog matches the factory bin. No cross-referencing third-party catalogs. The part numbers in this manual are the ones Dynapac stamped on the original boxes. I’ve seen too many blown head gaskets because someone used a generic gasket cut to “close enough” dimensions. Use the original part number from this catalog and avoid the rework.

Vibratory System: Drum and Eccentric Assembly

The CC522C is a combination roller, so the vibratory system is critical. This section covers the eccentric shaft, bearings, seals, and the drive coupling. Exploded views show exactly how the assembly comes apart and which shims go where. Torque values for the eccentric housing bolts are listed in the notes column. If you’re rebuilding the vibratory cartridge, you need those numbers. One stripped bolt in the housing can cost you a whole drum replacement.

3 Reasons This OEM Catalog Beats Aftermarket

First, the part numbers are verified by Dynapac’s own engineers. Second, the exploded diagrams are drawn to the original CAD files – not re-traced by some freelance illustrator. Third, the catalog includes supersession notes. When a part is replaced by a newer revision, the catalog footnotes it. Aftermarket catalogs often omit supersession history, so you order a part that was discontinued three years ago. That wastes time and money. This catalog, printed in 2004 and valid for serial numbers from *43020527* onward, gives you the part that fits.

Check Your Serial Number First

Before you order anything, confirm your roller’s serial number against the valid range listed on page 3 of the catalog. The SCC522C-2EN2 edition covers rollers from 2004 onwards. If your machine has an older serial number, you need the earlier edition – check out the DYNAPAC CC522C Spare Parts Catalogue SCC522C-1EN3 for rollers manufactured before 2004. Mixing editions leads to wrong fasteners and mismatched thread pitches.

Hydraulic System: Pump and Valve Breakdown

This section details the gear pump, charge pump, and the steering priority valve. Each valve body is shown with its internal components: spools, springs, seats, and O-rings. The parts list includes the factory recommended seal kit numbers. If you’re replacing a leaking hose or fitting, the catalog gives you the correct port thread size. Don’t trust an aftermarket chart for thread identification; use the Dynapac numbers.

For a complete list of factory parts for the entire Dynapac lineup, see the Dynapac CC522C Parts Catalog and the related Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec. Both contain the same level of OEM detail. If you work in the Automotive Industry Overview, you already know that OEM documentation is the only reliable source for heavy equipment repair. Automotive Industry Overview confirms that factory specs reduce warranty claim rejections by a wide margin.

Does this catalog cover the Cummins 4B 3.9 TAA engine completely?

Yes, the engine section lists every factory part number for the Cummins 4B 3.9 TAA.

How do I order parts using this catalog?

You need the roller serial number (found on the nameplate) and the part number from the diagram. On page 4, Dynapac lists the required information: machine type (CC522C), serial number, quantity, part number, part denomination, and dimensions if ordering by length. Provide all six to your dealer, and you’ll get the correct parts. If any info is missing, the dealer has to guess. That’s how you end up with a wrong bearing that takes three weeks to return. Use the catalog’s ordering checklist every time, and you’ll avoid those delays. The catalog also includes a blank line for your agent/dealer information on page 4.

If you’re serious about keeping your Dynapac CC522C in the cut and not on blocks, this 265-page Parts Catalog is the reference that belongs in your tool box. Access the Factory Manual now.
