Dynapac CA 121 D, CA 121 PD Parts Catalog

Ordering parts for a Dynapac CA 121 D or CA 121 PD vibratory roller without the factory catalog is a waste of time and money. You pull a seal, measure it with calipers, order something that looks close—then it doesn’t fit, and the machine sits for another week. I’ve seen it happen. This Parts Catalog eliminates that guesswork. It’s the same 150-page document Dynapac dealers use to look up genuine part numbers for the John Deere diesel engine, the vibration system, and every bracket and bolt on these rollers.

Page 3 lists the exact serial number ranges this edition covers: from 60310121 to 60310800. If your roller fits that range, this catalog gives you the exploded diagrams and factory part numbers—not some aftermarket renumbering. The engine is a John Deere diesel, and the catalog breaks down every component for it.

CA 121 D and CA 121 PD: Engine and Serial Number Ranges

Two models, one catalog. The CA 121 D is the smooth-drum version; the CA 121 PD is the padfoot. Both share the same John Deere power plant and many drivetrain parts. The serial number table tells you which issue of the catalog applies to your machine. If your serial number falls outside the range, you need a different revision—don’t guess. The catalog lists the valid range clearly on page 3. Without this, you might order parts for a different engine family.

Ordering Spare Parts – Six Requirements

Page 4 of the catalog lays out the six pieces of information you need to give your dealer: machine type, roller serial number, quantity, part number, denomination, and dimensions for bulk items. I’ve watched techs skip the serial number and get the wrong seal kit. Do not do that. This page is written in five languages, so even if your dealer’s counter guy can’t read Swedish, he’ll get it right. Write those six things down before you pick up the phone.

Parts Catalog: 150 Pages of OEM Data

This is not a reprint or a scan from a third-party. It’s the OEM publication from Dynapac (Metso Dynapac AB, Karlskrona, Sweden). The catalog shows exploded views with callouts matching the part numbers. You see the assembly, you read the number, you order that part. Nothing ambiguous. The 150 pages cover everything from the engine to the vibration exciter to the ROPS hardware. No missing pages, no faded lines—this is a direct digital copy of the factory catalog.

Aftermarket parts lists often leave out the engine serial number split or use generic descriptions like “seal kit” with no dimensions. That gets you a box of parts that don’t align. This catalog uses the exact Dynapac part numbers and references the original John Deere engine numbers. For any heavy equipment mechanic, that’s the difference between a job finished in a day and a machine down waiting on the wrong gasket.

How to Use This Manual on the Job

Pull the catalog up on your phone or tablet next to the machine. Find the exploded view for the section you’re disassembling. Tag the parts you remove with their numbers as you go. When you reassemble, you cross-check the view to make sure no washer is missing. The catalog doesn’t cover torque specs—that’s in the service manual—but for part identification it’s unmatched. One note: always check the serial number range on page 3 before ordering. Slight revisions happen, and Dynapac updates the catalog accordingly.

Unlike generic Automotive Industry Overview resources, this catalog is specific to compaction rollers. It’s built for the guy who needs part number 12345678 to repair a hydraulic hose on Monday morning.

FAQ

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views.

How do I use the serial number to find the correct parts?

The catalog includes a table of valid serial number ranges for the CA 121 D and CA 121 PD, as shown on page 3. You must locate your roller’s serial number, typically on a plate near the engine or frame. Then cross-reference with the published catalogue issue dates. For example, serial numbers 60310121 to 60310800 are covered by this edition. If your machine falls outside, you may need a different revision. Always order using the six-step process on page 4: machine type, roller serial number, quantity, part number, denomination, and dimensions if applicable. This prevents wrong deliveries.
