Dynapac CA512PD Parts Catalog – 344 Pages of Factory Specs

I’m Mike Callahan, 28-year ASE Master Tech. I’ve pulled wrenches on everything from a neglected Ford 300 to a Cat D6. When a Dynapac roller comes in with a blown hydraulic motor, the last thing I want is some aftermarket reprint with blurry diagrams and wrong part numbers. This Dynapac CA512PD Parts Catalog is what you need. 344 pages of OEM drawings, exploded views, and genuine part numbers. None of that third-party guesswork.

Before you order a single seal or bearing, you need the serial number range. This catalog is valid for CA512PD rollers from serial number 10000120x0A000001 onward. If your machine is older, you need a different edition. Dynapac issued this issue SCA512PD-4EN2 in October 2011. Check your roller’s plate before you buy anything.

Engine Cummins QSB 6.7C – Parts Breakdown

The Cummins QSB 6.7 is the heart of this roller. The catalog devotes a full section to the engine, including the cooling system (radiator, hoses), combustion air system, fuel system, and exhaust. You get OEM part numbers for injectors, turbo components, and gaskets. Page references are consistent throughout — every component ties back to an exploded view and a parts list with class codes (A = 3+ units per year, B = 2, etc.). If you’re rebuilding a QSB 6.7, you need these numbers, not aftermarket cross-references.

Hydraulic System Diagrams: Propulsion, Vibration, Steering

Hydraulics is where most rollers bleed money. The catalog covers the front propulsion motor (4700382088), rear propulsion pump (4700380830) and motor (4700373361), vibration pump (4700383959) with its rotating group and valve block (4700936609), steering pilot valve (4700372424) and cylinder (4700392027). There’s also a brake system section and options like central test panels and emergency steering. Each subsystem has its own exploded diagram. You can trace every O-ring, cartridge valve, and hose fitting back to a Dynapac part number. No guessing which seal fits the vibration motor — it’s right there.

Drum and Transmission – Don’t Overlook These

The drum section includes the drum cartridge for both vibration and drive sides, plus the drum gear. If you’re replacing eccentric shaft bearings or drum rotation components, the repair kit numbers are listed: 4700945657 for the eccentric shaft kit, 4700938891 for drum rotation kit. Transmission coverage shows two rear axle options: limited slip (4700385100) and No-Spin (4700383856). Each axle breaks down into differential with limited slip/no-spin, differential housing and brakes, and planet gear. Need a planet gear bearing? Page reference leads you straight to the part number.

Ordering Spare Parts: Page 2 Instructions You Must Follow

Dynapac prints ordering instructions on page 2 in six languages. They list six required pieces of info: machine type, roller serial number, quantity, part number, denomination, and dimensions if ordering by length. I’ve seen ten guys order the wrong scraper blade because they left off the dimension. The catalog also has a notes section on page 3 explaining how to read the parts list — the dot indentation means the part is included when buying the assembled unit above. That little detail saves you from double-ordering.

Why OEM Parts Catalog Beats Aftermarket Reprints

Aftermarket parts catalogs often renumber parts or skip obsolete versions. This is an original Dynapac publication, printed in Sweden. The part numbers match what your dealer uses. The catalog includes all options: heavy duty scraper, hood latch control, noise suppression, work lights, compaction meter, GPS, cab pre-heater, and more. If your roller has a field computer assembly or Geodynamic Compaction indicator, the wiring and hardware part numbers are in the electrical equipment section. You can also find decals and standard/optional equipment lists — critical for restoration or resale.

Does this catalog cover the Dynapac CA512PD after serial number 10000120x0A000001?

Yes. This issue SCA512PD-4EN2 is valid from that serial number onward. If your machine is older, you need the previous issue. Check the serial number plate on the roller frame.

What about the Cummins QSB 6.7 engine parts?

The catalog includes the full engine section with cooling, fuel, combustion air, and exhaust systems. You get OEM part numbers for the QSB 6.7C including injectors, turbo, and gaskets.

Are part numbers the same as what Dynapac dealers use?

Yes. This is the factory spare parts catalogue used by dealers. The part numbers and illustrations match exactly what Dynapac supplied. No aftermarket renumbering.

How many pages and what format?

344 pages in PDF format. Contains exploded view diagrams, parts lists with class codes, and ordering instructions in multiple languages.

Access the Factory Manual and keep a copy on your shop tablet. When a roller comes in leaking from the vibration pump valve block, you’ll have the right part number in under a minute.
