Dynapac CA402D Parts Catalog

If you run a shop that works on compaction equipment, you know the headache of ordering the wrong part. A misread part number or a missing digit can leave a roller down for days. This Dynapac CA402D Parts Catalog is 339 pages of factory-sourced exploded views and part numbers. No aftermarket guesswork. I’ve been wrenching in San Antonio for 28 years, and I won’t touch a job without the OEM book. This one covers the CA402D vibratory roller with the Cummins QSB 4.5 diesel engine.

Ordering Spare Parts: The Critical Details

First thing you’ll see on page 4 is the ordering information. They spell out exactly what you need: machine type, roller serial number, quantity, part number, denomination, and dimensions if buying by length. I’ve watched techs skip the serial number step and end up with a seal that doesn’t fit. This catalog makes it clear. The printed issue date and valid serial numbers are listed on page 3. SCA402D-3EN3 covers from roller serial number 69411200*. SCA402D-3EN2 was replaced in 2009. Don’t assume the newest is compatible—check the serial range.

7 Systems Covered in Exploded Views

The group numbering system is straightforward.

This parts catalog breaks down the Dynapac CA402D into groups. Page 5 shows a “GROUP PAGE” structure with notes and changes. While the full TOC isn’t in our scan, you can see the indexing system. You’ll get views for the vibratory system, steering, brakes, engine mounting, frame, electrical, and more. Each group lists every fastener, hose, and bracket. Need a specific bushing? The exploded diagram with callouts gets you the correct part number. No flipping through twenty pages of generic diagrams.

Does the Catalog Cover the Cummins QSB 4.5?

Yes. Page 3 lists the diesel engine as Cummins QSB 4.5. This catalog includes all parts related to the engine installation, cooling, fuel system, and air intake. But note—this is a parts catalog, not a service manual. You won’t get torque specs or repair procedures here. What you do get is the exact part numbers for engine components. If you need the oil filter or a fuel injector line, the diagram on the respective group page will show it. For repair steps, you’d want the Dynapac CA402D 2011 Parts Catalog which might be a different document—check the description.

Check the Serial Number Before You Order

Every Dynapac CA402D roller has a serial number stamped on the frame. This catalog is valid for serial numbers from 69411200*. If your machine falls outside that range, you need the earlier issue SCA402D-2EN4. DYNAPAC CA402D Spare Parts Catalogue SCA402D-2EN4 is likely the one for older units. I’ve seen guys order a steering cylinder for a 2008 roller using this catalog and it didn’t fit because the serial was just before the break. Always check the serial number against the valid range printed on page 3.

OEM vs Aftermarket Reprints: Why Original Matters

You can verify this manual’s authenticity by the Dynapac logo and the note “Part of the Atlas Copco Group” on page 1. The copyright is Swedish, printed in Sweden. No third-party reprint has the same layout or part number indexing. Aftermarket catalogs often crop images or omit the ordering instructions. This one includes the full multi-language ordering section (English, Swedish, German, Italian, Spanish, French) on page 4. That alone tells you it’s factory. I’ve seen Dynapac official dealer parts lists—this matches their format exactly. When you’re cross-referencing a part number, you need the exact diagram layout. Aftermarket versions sometimes renumber callouts or use generic descriptions. That leads to ordering mistakes. This catalog was designed by Dynapac engineers. The grouping, the notes, the change history on page 5—it’s all there for a reason. I’ve had techs bring me aftermarket catalogs and complain they can’t find a part. Nine times out of ten, the OEM catalog has it listed under a different group. Don’t cut corners on documentation.

Real-World Use Case for Shop Owners and DIYers

If you own a CA402D and do your own maintenance, this catalog saves you from calling the dealer for every part number. Pull it up, find the group, identify the part, and order it yourself. For a shop, it’s essential for accurate quotes. You can look up the part number, check availability, and give the customer a firm price. No more “I’ll call you back after I look it up.” Automotive Industry Overview isn’t relevant here, but the point stands: accurate parts data keeps the workflow smooth.

Frequently Asked Questions

What year is this catalog for?

2009 issue, valid from serial 69411200*.

Does this catalog include service procedures?

No. This is a parts catalog (spare parts catalogue). It provides exploded views and part numbers, not repair steps, torque specs, or diagnostic procedures. For service information, look for the Dynapac CA402D service manual.

Can I use this catalog for a CA402 with a different suffix?

The CA402D is specific. The D indicates a variant, likely with the Cummins QSB 4.5. The catalog is explicitly for CA402D. Using it for a CA402 (non-D) may result in wrong parts. Check the engine and model plate.

How do I ensure I’m ordering the correct part?

Start by recording your machine type and roller serial number. Compare the serial number to the valid range printed on page 3 of this catalog – for issue SCA402D-3EN3, that’s from 69411200*. Next, locate the correct group in the catalog (e.g., vibratory system, steering). Find the exploded view for your component and note the callout number. Then find the corresponding part number in the list. Finally, order using the exact part number, denomination, and quantity. Ignore any of these steps and you risk receiving a part that won’t fit. The multi-language ordering instructions on page 4 emphasize this – they included it for a reason. I’ve seen too many returns because someone skipped checking the serial number. If your machine falls outside the range, you need the earlier catalog issue.

Don’t waste time with aftermarket PDFs that leave out critical details. Access the Factory Manual for your Dynapac CA402D and keep your parts ordering accurate.
