Dynapac CA 121 D, CA 121 PD, CA 121 Parts Catalog

You ever order a part for a Dynapac CA 121 D, CA 121 PD, CA 121 Parts Catalog–wait, you order a part for a Dynapac roller and get the wrong bearing because the parts guy guessed? I’ve seen that cost a full day’s labor. This Parts Catalog fixes that. It’s the factory-issued document that tells you exactly which part number goes where, from the engine mounts to the drum assembly. No aftermarket reinterpretation – just the OEM drawings and part lists Dynapac themselves use. 150 pages of exploded views and reference numbers, printed in Sweden by the people who built the machine.

150 Pages of Parts Breakdowns for Dynapac CA 121 Series

Page 3 lists the serial number range this catalog covers – from 60310121 to 60310800. If your roller’s number falls in that range, you’re good. If not, you need a different issue. Every page is an exploded diagram with a corresponding parts table. You can see exactly how the vibratory housing, the drum mount, and the John Deere diesel engine come apart. The catalog is organized by assembly groups, so you find the section for the hydraulic system, the transmission, or the frame without flipping through a phone book.

Order Parts the Right Way – Use the Serial Number

Page 4 spells out exactly what you need to give when ordering: machine type, serial number, quantity, part number, denomination, and dimensions if it’s a cut-to-length item. Ignore that and you get the wrong part. I’ve seen it happen. A shop I know ordered a drive motor by part number alone and the dealer shipped the wrong displacement because they didn’t verify the serial number. This catalog stops that. Along with Dynapac official documentation, you get the ordering checklist right there.

What’s Covered in This Spare Parts Catalogue?

The catalog covers the John Deere diesel engine (referenced on page 3), the entire vibratory roller assembly, the hydraulic system, the frame, and the operator station. It is a parts catalog – not a service manual. You won’t find torque specs, troubleshooting steps, or repair instructions. But if you need to identify that odd-looking seal or the correct filter cartridge, this is the only source that matches the factory build. For repair procedures, look for the Automotive Industry Overview service documentation (though that’s a stretch – this is heavy equipment, not cars).

Diesel Engine Section: John Deere Specs and Part Numbers

The engine section breaks down the John Deere powerplant into subassemblies: cylinder head, injection pump, oil pan, cooling system. Each part number cross-references to the illustration. If your roller’s diesel needs a new injector line, you find the exact bend and length in the diagram. No aftermarket cross-reference that might be a millimeter off. This catalog uses the same part numbers Dynapac puts on their assembly line.

3 Things to Check Before Ordering from This Catalog

1. Serial number on page 3 – make sure it falls in the range 60310121-60310800.
2. Part number from the exploded view – compare it to the table, not the picture.
3. Quantity needed – some parts are sold per each, others per pack. The denomination column tells you.

If you also work on cold planers, the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec and Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer are available.

OEM Source: Why This Catalog Beats Aftermarket Reprints

This is the Swedish factory original, not a scanned copy from a third party. The line art is crisp, the part numbers are legible, and the ordering info on page 4 is in multiple languages – English, Swedish, German, Italian, Spanish, French. Aftermarket reprints often lose the page grid or blur the numbers. You don’t want to order a $400 pump off a blurry number. This is the real thing. For the companion service manual, check the Dynapac CA 121 D/PD Parts Catalog – that’s the same model, but be aware this is separate from the service manual.

Frequently Asked Questions

Does this parts catalog include repair procedures?

No. It only lists part numbers and diagrams.

How do I know if this catalog matches my roller?

Check the serial number range on page 3. If your roller serial number is between 60310121 and 60310800, this is the correct edition.

Can I order parts directly using this catalog?

Yes. The catalog is designed for ordering. Page 4 explains the exact information you need to provide: machine type, roller serial number, quantity, part number, denomination, and dimensions if applicable. Dealers and parts suppliers expect this format. If you give them just a part number without the serial number, they might send the wrong revision. Always include the roller serial number from the tag. This is critical because Dynapac updated parts across different production runs. Using the catalog’s exploded views, you can identify the exact component before ordering, saving a return trip.

Is this the same as a factory service manual?

No. A service manual covers repairs, adjustments, torque specs. This parts catalog only shows part numbers and exploded views.

No aftermarket knockoffs. This is the Swedish factory original. 150 pages of parts data that will keep your roller running and your parts counter happy. Ready to stop guessing? Access the Factory Manual.
