Dynapac CC422 Parts Catalog – Factory Part Numbers & Ordering Info

Let me be straight with you. I’ve spent decades in a shop bay, and I’ve seen jobs go sideways because someone ordered the wrong part from a generic list. That’s not going to happen with the Dynapac CC422 Parts Catalog. This is the original factory document, not some third-party copy. It’s got 325 pages of exploded drawings, genuine Dynapac part numbers, and the exact ordering procedure the manufacturer uses. If you’re working on a CC422 vibratory tandem roller and you need to buy a replacement component, this catalog is your only reliable source.

Why You Need the OEM Parts Catalog for the CC422

A common mistake is assuming that any parts list on the internet matches your specific machine. It won’t. The CC422 has multiple catalog editions depending on the serial number range (SCC422-3EN1 through SCC422-3EN4). This catalog covers all those updates up to 2007. Without the correct edition, you risk ordering a part that doesn’t fit, and then you’re stuck with a roller on blocks while you wait for a return. I’ve seen that happen more times than I want to count. The factory catalog eliminates that guesswork.

Ordering Spare Parts: The Six Critical Details

Flip to page 4 of the catalog and you’ll find the ordering checklist printed in six languages. The factory demands six pieces of information before they ship anything: machine type, roller serial number, quantity, part number, part denomination, and dimensions if ordering by length. If you skip any of those, you’re asking for a wrong part. I’ve had junior techs try to order a spray bar nozzle using just “nozzle for CC422,” and that gets you nowhere. This catalog makes you do it right. Use it every time you call your dealer.

What’s Inside This 325-Page Parts Catalog?

The document is organized by groups. You get exploded-view diagrams with every nut, bolt, hose, and seal called out by an individual part number. The engine section covers the Cummins 4B 3.9 TAA diesel that came in this model. There are separate groups for the vibratory system, the water spray system, the frame and steering, and the electrical components. Because the catalog uses group numbers (like Group 3 for the engine), you can pull up the exact page without flipping through the whole book. And yes, it includes the part numbers for the decals and the operator’s seat—stuff that generic parts houses never stock correctly.

Cummins 4B 3.9 TAA Engine: Parts Breakdown

That engine is a workhorse, but it uses specific gaskets, injectors, and turbo components that vary by serial number. The catalog breaks down the Cummins 4B 3.9 TAA into sub-assemblies: cylinder head, lubrication system, fuel system, cooling system. Every part that has a factory part number is listed right there. I’ve seen people buy an aftermarket injector for a different engine variant and then wonder why the compression is off. Don’t do that. Get the numbers from this catalog and order with confidence.

How to Use This Manual on the Shop Bench

When I work on a CC422, I keep this catalog open next to the workshop manual. The parts catalog tells me what to buy; the Dynapac CC222 CC232 CC422 CC522 CA602 Workshop Manual tells me how to install it. The two complement each other. If you need the assembly instructions and torque values, you want the Dynapac CC222/422/522 Workshop Manual. But for identifying that one mysterious bracket or figuring out the correct hydraulic hose length, this parts catalog is the answer. I recommend printing the relevant group pages and taping them to your toolbox so you don’t get grease on the original PDF.

The Difference Between OEM and Aftermarket Parts Lists

Aftermarket catalogs often use generic part numbers that cross-reference to multiple brands. That introduces errors. The Dynapac CC422 Parts Catalog uses only genuine Dynapac numbers. If a bolt is superseded, the manual notes the change. No guessing, no “this might work” logic. The original manufacturer’s engineering team designed these parts; why would you trust someone else’s database? Stick with the factory data.

And if you need the latest updates from the manufacturer, go directly to Dynapac.

Frequently Asked Questions

Does this catalog include the wiring harness part numbers?

No. Electrical harnesses are covered in the workshop manual, not this parts catalog.

How do I find the correct part number for the water spray system?

Open the catalog and locate the group index near the front. The spray system is typically in Group 7 (or Group 8 for later editions). Each page shows an exploded diagram with callout numbers. Match the callout to the part number list on the facing page. Double-check the serial number range printed at the top of the table; Dynapac changed the spray bar design after serial number 42520422. If your roller is newer, use the second table. I’ve had to order the wrong spray nozzle once because I used the old group page. That cost me a half-day waiting for the correct part. Check the serial number first—it’s stamped on the frame near the hitch. This catalog saves you that headache if you follow the procedure.
