Dynapac CA250-IID 2011 Parts Catalog

Look, I’ve been turning wrenches for 28 years, and I’ve seen more botched repairs from wrong parts than from bad torque specs. You’re working on a Dynapac CA250-IID vibratory roller. The job stops cold when you pull a part that doesn’t match. That’s why this 2011 Parts Catalog – 226 pages of OEM exploded views and part numbers – sits on my bench. It’s the same book the dealer uses, printed by Dynapac (now part of Atlas Copco).

Ordering Spare Parts: The 6-Point Checklist

On page 2, the manual prints the ordering protocol in six languages. You need: machine type, roller serial number, quantity, part number, denomination, and dimensions if ordering by length. Miss one of these and the warehouse sends you the wrong bracket. I’ve seen mechanics order a hydraulic pump for a CA250 based on a photo from a forum, only to get the wrong displacement because the serial number indicated a different pump group. This catalog eliminates that. Every part is linked to a specific serial number range. You flip to the group, cross-reference the serial number printed on your machine’s nameplate, and order the exact part. No returns, no downtime waiting for the correct piece. That’s the difference between a dealer-supplied catalog and a third-party PDF that stripped out the revision tables. The Dynapac company ensures the part numbers align with the production run of your roller.

How This Parts Catalog Is Organized

On page 3, the manual explains the group structure. The parts list sits next to an exploded diagram. Dots indicate sub-assemblies: parts indented under an assembly are included when you buy that assembly. The spare parts class code – ‘A’ means 3 or more in stock – is listed. This organization saves you from having to cross-reference multiple pages. For example, the Cummins QSB 4.5C diesel engine section groups the cylinder head, injection system, and cooling components as separate groups. You go straight to the group number, find your part number, and order. If you need a similar catalog for a different machine, check the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec.

3 Reasons to Use OEM Parts Catalogs

Reason one: aftermarket catalogues mix up revisions. Reason two: you get the correct serial number ranges. Reason three: the exploded view shows exactly how parts nest together.

That saves hours of cross-referencing.

What the 226 Pages Cover

The 226 pages include the complete roller: vibratory system, frame, hydraulic circuit, electrical harness, and the Cummins QSB 4.5C engine details. Each part number is unique to the CA250-IID. The catalog covers serial numbers from 10000108x0D007680 upward. If your machine is older, you need the previous issue (SCA250D-US5EN1). The publication notes on page 3 list the valid serial ranges. Always verify your serial number before ordering. For other Dynapac models, see the Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer and the Dynapac PL2000LS Parts Catalog – OEM Spare Parts Listings.

Parts Service Info & Changes

This catalog includes a notes section for specific items. Publication issues are tracked: issue SCA250D-US5EN1 was replaced by EN2 in September 2011. The version you get is the latest EN2, covering rollers from that serial range. Understanding the Automotive Industry Overview helps, but this catalog gives you the exact numbers without guesswork.

Does this catalog cover the engine?

Yes, the Cummins QSB 4.5C is listed on page 2.

What if I have a later serial number?

The catalog covers rollers from serial number 10000108x0D007680 upward. If your machine has an earlier serial number, you need the previous issue – SCA250D-US5EN1. The publication notes on page 3 explain how to check. Always verify your serial number before ordering; otherwise you’ll get parts for a different revision. I’ve seen that cost a shop a full day of downtime because the hydraulic pump bracket shifted by half an inch between production runs. This catalog prevents that kind of mistake by tying every part number directly to the serial number range listed in the header of each group page.
