Dynapac CA 302 D Parts Catalog – Factory Specs You Can Trust

Dynapac CA 302 D Parts Catalog – I’ve been turning wrenches for 28 years, ASE Master, own a 6-bay shop in San Antonio. You’re reading this because you’ve ordered the wrong part before, right? A seal that’s 2mm off, a bearing that doesn’t fit the hub. That’s what happens when you use aftermarket drawings or a third-party parts list that some kid typed up from a blurry photo. This 419-page document is the real thing – OEM from Dynapac, Sweden. Not a reprint, not a scan of a scan.

Flip to page 5 and you’ll find the Notes section – that’s where you write the serial number of your specific roller so you don’t lose track. The manual lists ordering info in six languages: part number, denomination, quantity, dimensions. You give that to your dealer and the box shows up with the right gasket. That’s the difference between a day lost and a job finished.

7 Sections That Cover Every Assembly

The catalog breaks down the CA 302 D into individual groups – engine, drive train, vibration system, steering, hydraulic tank, frame, and cab. Each group has exploded-view diagrams with callouts. No guesswork about which bolt goes where. The OEM part numbers match the Dynapac factory database. If you’ve ever tried to cross-reference a part using a generic supplier catalog, you know the headache. This kills it.

How to Order Parts Correctly (From Page 4)

Page 4 of the catalog spells it out: type of machine, roller serial number, quantity, part number, part name, and dimensions if it’s a length item. You’d be surprised how many guys skip the serial number and then get a part from a different revision. The CA 302 D had multiple catalog issues – SCA302D-1EN1 through -1EN5. This version (EN5, published 2002-10) covers rollers from serial number *68220308-* and up, with the Cummins 4BTA 3.9 Elite engine. If your roller is older, check the serial range on page 3.

Does This Manual Cover Aftermarket Modifications?

No. It’s the OEM parts catalog. If you’ve swapped in a different engine or changed the hydraulic pump to a non-Dynapac brand, the part numbers here won’t apply. You’ll need to measure and adapt. But for a stock CA 302 D, this is the only source you should use. I’ve seen shops try to use a generic vibration-drum diagram from a universal parts book – those end up with a $600 mistake because the bearing carrier has a specific step dimension.

3 Reasons to Choose the OEM Parts Catalog Over Third-Party

1. Part numbers come directly from the factory – no translation errors. One number per part, period.
2. Exploded views show the exact assembly order. That helps during teardown so you know which bolt comes out first.
3. Revision history is documented. You can see which parts were superseded and when.

If you need a parts catalog for a different Dynapac model, check the Dynapac CA 302 D Parts Catalog – 419 Pages, OEM Spare Parts and related machines like the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec or the Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer. All are factory originals, not copies.

What Engine Does This Cover?

Cummins 4BTA 3.9 Elite. That’s the diesel powerplant in the CA 302 D covered by this catalog. The engine section has its own group pages with part numbers for injectors, fuel pump, turbo components, and cooling system. If you’re rebuilding the engine, you’ll still need a separate engine service manual for torque specs and clearances. This catalog only covers replacement parts – not repair procedures. Don’t confuse the two.

Is This a Service Manual or a Parts Catalog?

Parts catalog. Plain and simple. It gives you the exploded diagrams and part numbers so you can order what you need. If you want to tear down the vibration system, you need the service manual for torque values and disassembly steps. The catalog shows you what the assembly looks like and which part number goes where. Both are necessary, but they aren’t the same thing. Know the difference before you start.

Frequently Asked Questions

Will this catalog work for a CA 302 that isn’t a D model?

No. The CA 302 and CA 302 D have different engine and drivetrain configurations. The D designates the Cummins engine; earlier models used Deutz. Using the wrong catalog will get you wrong parts.

How do I find a part number for the vibration motor?

Look in the vibration system group – it’s typically near the middle of the catalog. Each diagram has a part number callout. Match the callout to the list on the facing page. If you need help, contact your dealer with the roller serial number.

Can I return a part if I order the wrong one?

That’s between you and your supplier. The catalog helps you order correctly by giving you the exact OEM number. Measure twice, order once.

What if my serial number is older than the range listed?

You need an earlier revision of the catalog – SCA302D-1EN4 or earlier. This EN5 version starts at serial 68220308-. If your number is lower, the parts may differ. Dynapac superseded many parts over the years; check with your dealer for cross-reference.

Look, I’ve bent enough wrenches to know that the right manual saves more than time – it saves your wallet and your temper. This OEM parts catalog is the one Dynapac techs use. Don’t settle for a copy or a compilation. Get the real thing from a trusted source. If you work on heavy compaction equipment, you need this on your bench. Download the Factory Manual and stop ordering the wrong part.
