Dynapac CA302D Parts Catalog – What the Factory Uses to Order Parts

If you’re turning wrenches on a Dynapac CA302D Parts Catalog is not a luxury – it’s the difference between a part that fits and a part that sits on a shelf. I’ve seen too many guys try to cross-reference from a generic parts list and end up with the wrong bearing, the wrong seal, or a hydraulic fitting that leaks. This is the OEM document. 364 pages of exploded views, callouts, and part numbers keyed to the exact serial number range of your roller.

I spent twenty-eight years torquing head bolts and tracking down parts for everything from pickups to pavers. When a machine comes in with a blown hydrostatic motor, you don’t have time to guess. You need the factory diagram and the OEM part number. This catalog gives you exactly that – no aftermarket interpretation, no third-party database. It’s the same document the dealer’s parts counter uses.

Ordering Spare Parts: The 6 Pieces of Information You Need

Page 4 of this catalog lists the six things you must provide when ordering. Machine type. Roller serial number. Quantity. Part number. Part name. And dimensions if you’re ordering by length. Miss one, and the dealer ships the wrong part. That’s not speculation – it’s written right there in the manual in five languages. The manufacturer knows that the CA302D has multiple revisions tied to serial number ranges, and if you give the wrong serial number, you’ll get parts for a different build. I’ve had it happen. It costs time and money.

For example, this catalog edition (SCA302D-3EN3) is valid from roller serial number 68411200 and up. Earlier editions had different part numbers for certain components. Without the serial number, you’re guessing. The OEM catalog removes the guesswork.

Dynapac CA302D Parts Catalog Scope

This is a parts catalog, not a service manual. It won’t tell you how to rebuild the hydraulic pump or adjust the eccentric weights. What it does is show every component in exploded view format, labeled with the OEM part number. Every nut, bolt, seal, hose, filter, and bracket. The catalog covers the entire vibratory roller: engine, drivetrain, vibration system, steering, hydraulic system, electrical, and frame. If you need to order a replacement part, this is the document you use to ensure you get the correct item the first time.

Engine Spec: CUMMINS QSB 4.5

Page 3 identifies the diesel engine as a CUMMINS QSB 4.5. That’s a 4.5-liter turbocharged four-cylinder common-rail engine. The parts catalog includes the engine section with all CUMMINS-sourced part numbers, filters, injectors, and gaskets. If you’re doing an engine overhaul, you’ll also want the CUMMINS service manual – but for ordering parts, this catalog is where you start. Don’t rely on a parts store lookup based on a serial number they might not have. Use the OEM numbers from this catalog.

Why an OEM Parts Catalog Beats Aftermarket

Aftermarket parts catalogs often re-label parts or use generic numbers that don’t cross correctly. I’ve had a hydraulic pump shipped that looked identical but had a different spline count because someone used a third-party directory. This catalog comes directly from Dynapac, part of the Atlas Copco Group. The manufacturer is Dynapac. The part numbers are the ones stamped on the components at the factory. You can verify them against the actual machine.

While this is construction equipment, the same principle applies across all mechanical repairs – the Automotive Industry Overview shows that OEM documentation is the gold standard for accuracy. This catalog is the same type of factory-authorized document that dealerships use internally.

Who Needs This 364-Page Document

If you own or maintain a Dynapac CA302D vibratory roller, you need this catalog. It’s for mechanics, fleet managers, and equipment owners who want to order parts correctly without paying dealer markup on part lookups. The 364 pages cover every revision from the serial number range listed on page 3. If your machine is within that range, every part number applies. Outside it? You need the earlier edition (SCA302D-3EN2 or 3EN1). We carry those too – Dynapac CA302D Parts Catalog and the DYNAPAC CA302D 2011 Parts Catalog are available if your serial number matches later production. There’s also a Dynapac CA302D Parts Catalog – 384-Page OEM Spare Parts Guide that includes additional revision notes.

I don’t recommend skimping on documentation. I’ve seen rollers sidelined for weeks because someone ordered a steering cylinder from a generic cross-reference. The factory catalog costs a fraction of one wrong part order. If that matters to you, Access the Factory Manual below.

What engine does the Dynapac CA302D use?

CUMMINS QSB 4.5.

What information do I need to order spare parts?

You need the machine type, roller serial number, quantity, part number, part name, and dimensions if ordering by length. The manual specifies this on page 4. Skipping any of these guarantees a wrong part in your hand. When you call your dealer without the roller serial number, you’re gambling. The catalogue explains exactly what to provide: type of machine, roller serial number, quantity required, part number, parts denomination, and dimensions if ordering per length. Miss one, and the delivery will be wrong. That’s why the OEM catalog includes this on page 4 in multiple languages – because part numbers alone aren’t enough if you give the wrong serial number range. The CA302D has multiple catalogue revisions tied to serial number ranges, and ordering from the wrong revision gets you parts that don’t fit.
