Dynapac CA612PD 2011 Parts Catalog – Factory Parts Breakdown

I’ve been turning wrenches since before some of you were born, and I’ve seen more wrong parts show up in a shop than I’ve had hot meals. Nothing kills a day faster than ordering a hydraulic motor that doesn’t match the serial number on your machine. That’s exactly why the Dynapac CA612PD 2011 Parts Catalog belongs on your bench – not some third-party knockoff PDF with blurred exploded views and missing part numbers. This is the same document Dynapac’s own parts counter uses. 344 pages, factory-original, with every nut, seal, and circuit board listed by part number and group.

7 Main Systems Covered

You don’t want a parts catalog that skips sections. This one covers every major system from frame to decals. The table of contents splits the CA612PD into: Service kits (50h, 500h, 1000h), Repair kits (steering hitch, eccentric shaft, drum rotation, shock absorber, F/R control button), Frame, Drum, Engine (Cummins QSB 6.7C with cooling, combustion air, fuel, and exhaust), Transmission (rear axle with limited slip or no-spin option, differential housing, planet gears), Hydraulic system (propulsion front and rear, vibration system with pump and motor, steering, brake, oil tank, emergency steering), Electrical equipment (all panels, lights, options like compaction meter, GPS, tachograph), Driver’s platform (two cab variants, seats, ROPS/FOPS), Decals, Standard and Optional equipment. That’s the full machine, not a summary.

Does This Manual Cover the Hydraulic System?

Yes – and it does it with part numbers for every component. The vibration system alone lists the vibration pump (4700393695) with its rotating group and valve block (4700936609), plus the hydraulic motor (4700380146). The propulsion system gives you both front motor (4700382088) and rear pump (4700380830) with part numbers. If you need to order a steering cylinder (4700392027) or pilot valve (4700372424), it’s in there. The brake system and hydraulic oil tank are separate sections. No guessing which O-ring goes where – the exploded diagrams tell you.

Order the Right Part the First Time

Page 2 of the catalog is the ordering information. It’s printed in six languages because parts mistakes are expensive in any language. You need: machine type, roller serial number, quantity, part number, part denomination, and dimensions if ordering by length. That’s it. If you skip the serial number, don’t blame Dynapac when the wrong axle shows up. The catalog explicitly states it’s valid from roller serial number 10000124x0A000001 onwards. Make sure your machine falls in that range before you order. Anything else is your own fault.

Engine: Cummins QSB 6.7C Coverage

The engine section breaks down the Cummins QSB 6.7C into cooling system (radiator), combustion air system, fuel system, and exhaust system. Each subsystem has its own parts list with exploded diagrams. If you’re rebuilding the fuel system, you get the exact part numbers for injectors, lines, and filters. The cooling system includes the radiator assembly. No need to cross-reference a separate engine manual – it’s all here. The 2011 publication date means these part numbers match the production run of that era. Later revisions might use different supersessions, but this is the baseline.

Transmission: Rear Axle Options

Two rear axle variants are cataloged: the limited slip (4700385100) and the no-spin option (4700383856). Each gets its own sub-section with differential, housing, brakes, and planet gears. If you’re swapping a differential or replacing axle seals, the part numbers are grouped under the correct assembly. The planet gear section shows exactly which bearings and spacers go where. This is the kind of detail that saves you a second teardown when the parts counter sends the wrong shim.

Source Authenticity: OEM vs. Aftermarket Parts Catalogs

I’ve seen aftermarket parts catalogs try to copy Dynapac diagrams. They always get something wrong – a wrong part number, a missing bolt, a reversed arrow. This is the genuine factory spare parts catalogue, published by Dynapac (part of the Atlas Copco group). The file name is Dynapac_CA612PD_2011_Parts_Catalog_en-26114002568.pdf. It’s the same document dealers use. If you want to verify the manufacturer, check the Dynapac official site. For context on why OEM documentation matters in heavy equipment, see this Automotive Industry Overview.

Who Needs This Catalog?

If you own a CA612PD roller and have ever tried to order a part by “looks about right,” you need this. DIY equipment owners, fleet mechanics, and home garage enthusiasts who work on their own compaction equipment will get the exact part numbers. No more calling the dealer and hoping the guy on the phone knows which drum cartridge you have. The 344 pages cover everything from the drum vibration side cartridge to the decals. Even the optional equipment – like the compaction analyzer, GPS, engine pre-heater, and tachograph – has its own section. If your machine has an option, it’s in here.

What year was this parts catalog published?

2011. The catalog issue date is 2011-10, valid from serial number 10000124x0A000001.

How do I use this catalog to order parts without getting the wrong item?

Open to page 2 and follow the six-step ordering info: machine type (CA612PD), roller serial number (must match the valid range), quantity, part number (from the exploded diagram), part denomination (description), and dimensions if ordering by length (e.g., hoses or wiring). Then cross-reference the part number in the appropriate group – for example, if you need a steering cylinder, go to Hydraulic system > Steering system and find 4700392027. Write it down exactly. Do not transpose digits. The factory part numbers are precise; one wrong digit gets you a pilot valve instead of a cylinder. If you’re ordering a service kit, use the 50h kit 4700945197, 500h kit 4700950324, or 1000h kit 4700945199 – they’re listed under Service kits. Match the kit to your maintenance interval. That’s how you avoid the weekend wasted with the wrong box on your bench.

Stop ordering parts by description and hoping for the best. Access the Factory Manual and get the right part number every time. Your machine – and your wallet – will thank you.
