Dynapac CA250STD Parts Catalog – OEM Factory Spare Parts for Vibratory Roller

If you’ve ever ordered a part for a Dynapac CA250STD roller and ended up with the wrong component, you already know the frustration. A missing serial number range or a misidentified engine code can cost you a week of downtime. This Parts Catalog fixes that. It’s the same document Dynapac dealers use when they punch in your order. No aftermarket guesswork. No photocopied diagrams with blurry reference numbers.

You get 395 pages of factory exploded diagrams, exact part numbers, and ordering instructions that cover every revision of the CA250STD from the CUMMINS 4BTA 3.9C diesel engine to the vibratory drum assembly. Each section is referenced to a specific serial number range so you order the right piece the first time.

What This Parts Catalog Contains

This isn’t a service manual. There are no torque specs or overhaul procedures here. What you get is a part-number-for-part-number breakdown of the entire roller. Every bolt, seal, hose, and hydraulic component is listed with its factory identifier. The catalog is organized by major assemblies: engine, hydraulic system, drum, frame, electrical. Each assembly has its own exploded view with numbered callouts that correspond to a parts list below the illustration.

The manual also includes the official Dynapac ordering checklist from page 2 of the catalog. You need six things: machine type, roller serial number, quantity, part number, part denomination, and dimensions if ordering by length. Skip any one of those and your order gets kicked back. That’s not speculation—it’s printed in the catalog.

Ordering Spare Parts: The Six Critical Details

On page 2 of the catalog, Dynapac spells out exactly what they need to ship you the correct part. First, the type of machine—CA250STD in this case. Second, the roller serial number. Third, the quantity you want. Fourth, the part number from the exploded diagram. Fifth, the part denomination (the name of the component). Sixth, dimensions if the part is sold by length, like hydraulic hoses or wire.

Aftermarket parts catalogs often skip these details or list generic part numbers that cross-reference incorrectly. That’s why you see mechanics in the field holding up a new seal that doesn’t fit. This catalog eliminates that because every part number is directly linked to the serial number range of your machine. Check the table at the front of the catalog—it lists every edition (EN1 through EN10) and which serial numbers each covers.

Diesel Engine Identification – CUMMINS 4BTA 3.9C

The CA250STD uses a CUMMINS 4BTA 3.9C diesel engine. The catalog includes a dedicated section for engine components. You’ll find the cylinder head gasket part number, the injector line set, the fuel filter head—everything. But you need to verify your engine serial number against the catalog’s compatibility list. Dynapac updated the engine parts section across multiple editions because Cummins introduced revisions. The catalog you access matches a specific serial number range, so cross-check it.

I’ve seen guys order a water pump based on a third-party website, only to find the bolt pattern is wrong. That doesn’t happen when you use the factory catalog because the diagram shows you exactly which pump variant your engine takes.

395 Pages of Factory Diagrams – Why Size Matters

Three hundred ninety five pages might sound like overkill for a parts catalog. It’s not. Each assembly gets at least four pages: an overall view, a detail view, the parts list, and a notes page for revision changes. The drum assembly alone takes up over thirty pages because it includes the vibratory mechanism, the bearings, the seals, and the hosing that drives it. You need that level of detail to identify wear items correctly.

A typical aftermarket catalog gives you one generic diagram for the drum and then lists parts that fit multiple models. That’s how you end up with a seal that’s 2 mm too thick. This catalog is specific to the CA250STD—no overlap with the CA250D or CA250PD. Every reference number is unique to this model.

Verify the Serial Number Before You Order

Dynapac issued at least ten editions of this catalog (SCA250STD-1EN1 through 1EN10). Each edition covers a specific range of roller serial numbers. The edition you need depends on your machine’s serial number. The catalog’s front matter lists the valid serial numbers for each edition. If you order parts from an edition that doesn’t cover your serial number, you risk getting superseded parts that may not fit. Always check the table on page 3 of the catalog.

This isn’t a suggestion—it’s a hard requirement printed in the catalog itself. Dynapac states: “Valid from roller serial number: …” and then lists the range. Ignore that and you’re gambling.

Why This Catalog Beats Aftermarket Copies

Aftermarket parts catalogs for the CA250STD are usually scanned from older editions, missing the later revisions. The OEM factory print includes every update up to edition EN10. The diagrams are high-contrast, the text is sharp, and the part numbers are directly from Dynapac’s inventory system. When you call a dealer and read them a part number from this catalog, they don’t ask for clarification because the number is current in their system.

Official Dynapac documentation like this is what separates a one-hour repair from a three-day hunting expedition. The principles of correct part identification apply across the Automotive Industry Overview, even if your machine is heavy construction.

Does this parts catalog include torque specs or repair procedures?

No. This is a parts identification manual only. You need the separate service manual for disassembly and torque values.

How do I find the correct part number for my CA250STD if I don’t have the serial number handy?

You need the serial number. It’s stamped on the frame near the engine or on the data plate. The catalog groups parts by serial number range, so without that number you will likely order the wrong component. Dynapac lists the serial number range at the start of the catalog and again on each major section. If you cannot locate the serial number, contact a Dynapac dealer with the model and year. Do not guess.

Can I use this catalog for the CA250D or CA250PD?

No. This catalog is specific to the CA250STD. The diagrams and part numbers differ between submodels.

What if my serial number falls between two catalog editions?

Use the higher edition number if your serial number is above the listed range. The editions are cumulative—the later edition includes all parts from previous editions plus new revisions. The catalog’s front matter explains the overlap. If your serial number is below the earliest edition, you may need a legacy catalog. Contact us for verification.
