Dynapac CA 251, CA 301 Workshop Manual – What You Get When You Buy the Factory Book

If you are maintaining a compaction roller from the Dynapac CA 251 or CA 301 family, you already know the problem. Aftermarket PDFs leave out the critical numbers – the hydraulic charge pressures, the fastener tightening sequences, the exact clearances for the vibratory system. One wrong spec on a 12-ton machine and you are looking at a tow bill you cannot bill back. The Dynapac CA 251, CA 301 Workshop Manual fixes that. This is the OEM document that came with the machine from the factory. 422 pages, multiple languages, and every torque value comes straight from Svedala Compaction Equipment AB. Not a reprint, not a third-party rewrite. Original factory print.

Safety Directives: Why This Section Is Not Optional

Page 4 of this manual opens with the Safety Manual – five chapters covering safety directives, operating procedures, transport, refuelling, and repair/maintenance. Each one is printed in English, German, Swedish, French, Italian, Spanish, Norwegian, Danish, and Portuguese. That is not padding. That is liability prevention. If you are working on a CA 251 or CA 301, you need to know the machine-specific lockout points and the correct way to lift the drum assembly. The generic “lock out tag out” posters in your shop do not cut it. The manual tells you exactly where the hydraulic pressure has to bleed down before you crack a line. Skip this section and you risk 3,000 psi of residual oil in your face. Not a comfortable conversation with the shop foreman.

Does This Manual Cover Both CA 251 and CA 301?

Yes. The title page lists both models, and the document is indexed under order numbers OMS-251SE, OMS-251EN, OMS-251US, and the corresponding numbers for DE, FR, ES, IT, NO, DK, PT. That means one manual works for both rollers – Deutsch or Cummins engine variants. The engine chapters are separated by a bookmark section labeled “DEUTZ X CUMMINS”. If you need the spare parts catalogue to go with it, look at the Dynapac CA 251/301 Spare Parts Catalogue S-241-4. For the full parts breakdown, the DYNAPAC CA 251/301 Spare Parts Catalogue covers everything from bearings to hydraulic seals. Both of those are separate documents – this workshop manual is the repair procedures.

422 Pages: What You Get in This Workshop Manual

422 pages is not a number the marketing department picked. It is the sum of safety, operation, maintenance, spare parts lists, and engine warranty/instructions sections. The document structure mirrors the original binder: Safety Manual (page 4), Operation (page 4), Transport (page 4), Refuelling (page 4), Repair and Maintenance (page 4) – each section starts on the same physical page number because the manual is printed in nine languages. The English portion alone runs through the safety directives, driving instructions, transport rules, fuel handling, and the full repair maintenance chapter. You get the same content a dealer technician would have on his cart.

Understand the Transport and Refueling Procedures

These are not the same as a truck. A roller has its own braking system, axle locks, and a fuel tank that sits near the engine compartment. The manual gives you the steps for tie-down points, weight distribution, and the approved refueling nozzle. Ignore them and you could damage the hydraulic tank baffle or overfill the diesel. Page 10 of the manual includes the warranty registration tear-off and the list of optional instructions – things like cold-weather start kits or high-altitude governor changes. That page alone has saved my customers money on parts they did not need.

OEM Documentation: Aftermarket Manuals Fall Short

I have seen aftermarket manuals claim to cover Dynapac CA 251 and CA 301, but they cut corners. They might give you a generic bolt torque chart that does not account for the hardened washers on the vibratory housing bolts. Or they skip the safety directives entirely. This manual is an original OEM print from Svedala. The .pdf file name – DYNAPAC_CA_251-CA_301_Workshop_Manual_de-en-fr-it-26128013593.pdf – tells you it is the same document sold through Dynapac dealers. No scanning artifacts, no missing pages, no blurry wiring diagrams. If you need the electrical schematics for a different Dynapac model, check the Dynapac CP142, W3020 2007 Workshop Manual – OEM Electric Diagrams. That manual covers a different family, but the wiring format is the same factory standard.

7 Systems Covered – What Else Is Inside

Beyond the main repair chapter, the manual includes the engine section (warranty terms and operating instructions) and a spare parts catalog index. The engine chapters are separated into warranty, instructions, and spare parts – cumulatively covering the Deutz and Cummins power units. The vibratory system, hydrostatic drive, steering, and brake circuits are all inside the repair maintenance chapter. If you need the Manual Transmission section for a different piece of equipment, that is a separate document – this one is all about the roller. Use Manual Transmission for transmission-specific data on other machines.

Frequently Asked Questions

Is this the same manual a dealer would use?

Yes. It is the identical PDF that Dynapac dealers receive. Same page numbers, same torque charts, same safety warnings. No aftermarket condensation.

What languages are included?

English, German, Swedish, French, Italian, Spanish, Norwegian, Danish, Portuguese. The safety and repair chapters are repeated in each language.

Will this manual help me rebuild the hydraulics?

Absolutely. The repair and maintenance chapter covers disassembly, assembly, and testing for the pump, motor, and valve bank. You get the adjustment specs for pressure relief valves and the flow rates for the charge pump. That is the kind of data aftermarket sources leave out because they do not have access to the factory test rigs. Without it you are just guessing on shim stacks and spring preloads – and a blown hydrostatic unit costs more than a dozen of these manuals.

Do I need a password to open the PDF?

No. The file is unlocked, printable, and searchable. You can print a single page for the toolbox without restrictions.

If you are serious about keeping a Dynapac CA 251 or CA 302 on the job, you need the spec sheet that came from the factory. Access the Factory Manual now – it is the same 422-page document that saves dealer techs from making expensive mistakes. No guesswork, no aftermarket shortcuts. Just the OEM data your shop deserves.
