Dynapac CA25, CA 25 A Parts Catalog

If you’ve ever ordered a part for a Dynapac CA25 or CA 25 A and ended up with the wrong seal, the wrong bearing, or a bracket that doesn’t line up, you know the cost of guessing. The Dynapac CA25, CA 25 A Parts Catalog is the OEM document that eliminates that guesswork. It’s not a repair manual — it’s a parts identification bible. 252 pages of exploded drawings, group-system indexing, and factory part numbers. Period.

The Dynapac Group System: How Parts Are Organized

This catalog uses a group numbering system common to all Dynapac spare parts catalogs. You get a list of contents first, then groups and sub-groups in numerical order. Each group starts with its own contents page. A section consists of one page with an exploded drawing and one or more pages of tables. The drawing shows the assembly; the tables list the part number, quantity per set, and description in two languages. The part number column is what you give the dealer. No interpretations, no “maybe this fits.”

Does This Catalog Cover Your Engine Variant?

Three engine options are listed on page 1: Caterpillar D320B, Deutz F6L 912, and Detroit Diesel GM 3-53 T. The catalog covers all three. If your CA25 or CA 25 A has one of these engines, the exploded views and part numbers in this book apply. If you’ve got a different power plant, you’ll need a different catalog. Don’t assume compatibility — Dynapac built them with specific engine packages, and this document reflects that.

252 Pages of Exploded Diagrams and Part Numbers

Every page is a high-contrast line drawing with callout numbers matching the table. The tables show the set number (the circled number on the drawing), quantity required, part number, and description. An asterisk next to the set number means that part was revised in the current issue. This is the level of detail you need when you’re trying to match a hydraulic fitting or a vibration mount. Aftermarket catalogs often collapse multiple variants into one blurry photo. This is the real thing.

Engine Options: Caterpillar D320B, Deutz F6L 912, Detroit 3-53 T

The catalog splits the roller into systems — frame, vibration, steering, braking, power train. Each system’s exploded view shows every nut, bolt, seal, and gasket. For the engine sections, the drawings are specific to the engine model. If you need a water pump gasket for a Deutz F6L 912, you look in the Deutz-specific group. The part number is there. No cross-reference guessing. The Detroit 3-53 T section is separate. The Caterpillar section is separate. That’s how OEM catalogs work.

Get the Right Part Number Before You Call the Dealer

Ordering parts without the factory number is a gamble. Machine downtime costs more than the part. This catalog puts the number in your hand before you pick up the phone. Each table has a quantity column — that tells you how many of that part come in a set (like a seal kit or a bearing pack). If the description says “cpln” (complete assembly), the parts below that line are included when you order the assembly. You don’t double-order. You don’t miss the internal circlip. The group system on page 2 explains all the symbols: circle O for complete, square A for sub-assembly. That’s the kind of detail that saves a Saturday.

Why OEM Documentation Matters for Construction Equipment

Aftermarket parts catalogs for vibratory rollers are rare. When they exist, they often renumber parts or show generic images. This is a direct scan of the Dynapac factory catalog. The same book the dealer’s parts counter uses. If you maintain a fleet of CA25 or CA 25 A machines — or even one — having this on your bench means you can cross-check supersessions, verify fastener quantities, and confirm that the part you’re looking at matches your serial number range. The catalog covers Series 2, S-10225-1 and later.

One paragraph that’s short: That’s the difference between a machine that runs and a machine that sits.

For related manuals, check the Dynapac CA25 1987 Parts Catalog – Section: Group 4 Transmission for transmission-specific drawings, or the DYNAPAC CA25 Spare Parts Catalogue for a direct reprint of the factory document. Another variant is the Dynapac CA25 1985 Parts Catalog if your machine is earlier. For more on the manufacturer, see the Dynapac history on their official site.

Frequently Asked Questions

Is this the same as the service repair manual?

No. This is a spare parts catalog — exploded diagrams and part numbers only. No torque specs, no service procedures.

Can I use this to order parts for a CA25 with a Deutz engine if my machine has a Caterpillar?

Each engine option has its own section in the catalog. The exploded drawings and part numbers are specific to that engine. If your machine was originally equipped with a Caterpillar D320B, the Cat-specific groups apply. Using the Deutz section would give you wrong part numbers. The catalog clearly separates them by group. Look at the group list to find the engine section that matches your machine’s VIN or engine serial. If you’re unsure, cross-reference the hydraulic pump or bellhousing pattern — but the safest bet is to match the engine model listed on the machine’s data plate. The catalog cover lists the three supported engines; if yours isn’t one of them, this book won’t cover it.

If you work on these rollers, you need the factory data. Access the Factory Manual now and keep it on your bench. That’s how you get the right part the first time.
