Dynapac CA 402 D 2002 Parts Catalog

Been burned by aftermarket parts that don’t fit? I’ve seen guys order a hydraulic pump seal kit from a third‑party list only to find the o‑ring groove is 0.5 mm off. That’s a day lost and a rental bill you can’t bill back. This Dynapac CA 402 D 2002 Parts Catalog stops that. It’s the original factory document – 407 pages – printed by Dynapac in 2002. Every part number, every exploded view, every dimension came straight from the engineering line. No guesswork.

Page 3 tells you exactly which serial numbers this catalog covers: valid from 69220403‑. Your roller is a CA 402 D with a Cummins 4BTA 3.9 Elite engine? Good, you’re in the right range. Page 4 shows the ordering format in six languages – machine type, serial number, quantity, part number, denomination, and length if it’s a cut‑to‑size item. Miss any one of those and the dealer sends you the wrong part. I’ve seen it happen twice this month alone.

What You Get in 407 Pages

Each section breaks down a major assembly: engine, hydraulic system, vibratory unit, frame, etc. Every part is drawn in an exploded view with a callout number that matches the parts table. The table includes the part number, description, quantity per machine, and sometimes a note (check page 5 for the notes key). This isn’t a service manual – no torque specs or repair steps – but if you need a piston seal, a bearing, or a hose, the factory PN is right there. Cross‑reference that with your serial number and you’re golden.

For the Cummins engine, look for the group covering the power unit. The catalog lists both the engine manufacturer’s part numbers and the Dynapac stock number. Use the Dynapac number when ordering from a Dynapac dealer – it ensures the part was tested for vibration and fit. Aftermarket bearings may look the same but fail in 200 hours on a vibratory roller. OEM specs exist for a reason.

Ordering Parts the Right Way

Open to page 4. There’s a six‑item checklist that every mechanic should tape to his toolbox. Let me run through it: machine type (CA 402 D), roller serial number (must match the range on page 3), quantity, part number exactly as printed, part denomination (don’t guess – use the English description from the catalog), and dimensions if the part is sold per length (hydraulic hose, wire, etc.). My shop once got a shipment of 20 o‑ring kits because the apprentice wrote “seal” instead of “o‑ring kit – 5 pcs.” The catalog says “O‑ring Kit” – use those words.

If the part number appears with a dash or a letter suffix, copy it exactly. Dynapac updates parts; the suffix indicates a revision. Ordering the old PN may get you a superseded part that still works, but only if the dealer knows the supersession chain. The catalog shows the current PN. Stick to it.

Serial Number Verification – Why It Matters

Page 3 lists the valid serial number range for this edition: 69220403‑ and up. If your CA 402 D has a serial number below that, parts may not interchange. Dynapac made running changes to the vibratory clutch and the hydrostatic pump around 2001. Ordering a pump for a 2000‑model year roller using this catalog would get you the wrong mounting flange. Always check the serial number against the catalog’s range before you place the order.

Keep in mind this is the spare parts catalogue, issue SCA402D‑1EN3, published 2002‑10. Newer editions exist for later serial numbers. If your roller is 2003 or newer, you need the subsequent catalog. But for the 2002‑era CA 402 D, this is the exact document the Dynapac dealer uses.

OEM Catalog vs Aftermarket Lists

Aftermarket parts websites often pull numbers from a database that mixes up years. I’ve seen a part listed for “CA 402 D all years” – that’s a lie. The roller changed its engine rating and drum mount after 2001. Only the factory catalog gives you the part number assigned to your specific serial number. The difference is the difference between a part that bolts in and one that needs five washers and a prayer.

Is This Manual Right for Your Dynapac CA 402 D?

If your roller is a CA 402 D with a Cummins 4BTA 3.9 Elite engine and a serial number starting 69220403‑, yes. This is the correct parts catalog. It does not include repair procedures, wiring diagrams, or torque specs – that information is in the service manual. Use this catalog alongside the service manual for full coverage. But for parts ordering, this is the only source you should trust.

Does this manual cover the Cummins 4BTA 3.9 Elite engine?

Yes. Page 3 lists the engine specification as part of this catalog. The engine group includes all part numbers for the Cummins power unit.

What should I do if my roller serial number is below 69220403-?

This catalog does not apply. You need the earlier edition: SCA402D-1EN2 or SCA402D-1EN1. Ordering parts from this catalog for an older roller risks mismatched components.

Are there torque specs or repair instructions in this parts catalog?

No. This is exclusively a parts identification and ordering catalog. Torque values, overhauls, and diagnostics are in the corresponding service manual. Do not attempt repairs without a service manual.

Can I use aftermarket part numbers instead of the OEM numbers listed?

Not recommended. Aftermarket cross‑references are often based on generic dimensions. Dynapac specifies certain fits for vibration resistance. Use the factory part number from this catalog; it’s the only number guaranteed to match your CA 402 D.

Every time I see a mechanic waste an afternoon returning the wrong seal kit because he used an aftermarket list, I point him to the factory catalog. It’s 407 pages of exactly one thing: correct part numbers for your machine. Don’t guess – use the document Dynapac built for this job. Access the Factory Manual and keep it on your tablet next to the toolbox.
