Dynapac CA-25 Parts Catalog

If you’re trying to keep a Dynapac CA-25 Parts Catalog roller running without factory parts numbers, you’re working blind. I’ve seen guys order a hydrostatic pump seal kit based on a guess and end up with the wrong part for a Detroit Diesel engine. That’s billable hours down the drain and a machine sitting on the lot. This parts catalog gives you the exploded views and OEM part numbers for every assembly on the CA-25. With 298 pages, it covers the tractor from the chassis to the water spray system. This is not a reprint – this is the actual factory document from Dynapac. Use it to cross-reference serial numbers before you call your parts supplier.

Dynapac CA-25 Parts Catalog: What You Get in 298 Pages

The table of contents lists over 50 assembly groups, each with its own parts breakdown. You get detailed exploded diagrams for the chassis (Grupo A-1), articulation (A-2), and connections (A-5). Every drawing includes callouts with OEM part numbers. No guessing which seal fits which pump – the manual tells you exactly which group to reference. The index is organized alphabetically in Portuguese, but the part numbers are universal.

Parts Coverage for Three Engine Options

This manual covers the CA-25 with Mercedes Benz, Caterpillar, and Detroit Diesel engines. Separate groups for accelerator, exhaust, air filter, cooling, and fuel system are dedicated to each powerplant. For example, Grupo C-6 covers the fuel system for the Mercedes Benz engine, Grupo C-17 for Caterpillar, and Grupo C-19 for Detroit Diesel. You won’t mix up a fuel line between engines because the illustrations are engine-specific.

Hydrostatic Pump and Vibration System: Key Assemblies

Two critical groups: the hydrostatic pump (E-3) and the hydrostatic pump for vibration (E-10). Both include the full pump assembly, seals, and mounting hardware. The vibration motor (E-15) and hydraulic motor (E-3) are in separate sections. If you need a replacement charge pump or a shaft seal, you’ll find the part number on the exploded view. No need to disassemble first – order the right parts off the drawing.

What the Brake System Section Actually Contains

Three brake groups: brake (D-8), emergency brake (D-9), and brake master (D-7). Each shows the entire hydraulic circuit including lines, cylinders, and adjustment hardware. The master cylinder assembly includes the reservoir and pushrod. I’ve had guys order a master cylinder that turned out to be for a different series – the group D-7 drawing will show you the exact casting number. Don’t trust aftermarket catalogs; use this.

7 Systems You Should Verify Before Ordering Parts

Before you place an order, cross-check these groups against your machine’s serial number: (1) Chassis (A-1) – frame reinforcements changed across production. (2) Articulation joint (A-2) – different wear plates. (3) Differential (D-5) – shim thickness varies. (4) Planetary axle (D-4) – bearing part numbers differ by series. (5) Steering cylinder (E-11) – seals differ. (6) Speed cylinder and piston (C-11) – rod diameter changes. (7) Instrument panel (F-4/F-5/F-6) – gauge cluster variations. The manual lists the valid serial ranges on page 3 – 681B243 through 687B831. Don’t skip that step.

Check the Serial Number Before You Order

Page 3 of the manual lists the serial numbers for which this catalog applies. If your CA-25 falls outside those ranges, you need a different parts book. The groups are indexed to those series. Ordering a water spray system (H-1, H-2) for the wrong series can leave you with the wrong bracket. The manual also includes a desert-condition air filter group (H-8) – not all machines have that. Verify your setup.

Factory documentation like this eliminates the guesswork. I’ve been turning wrenches 28 years, and I can tell you that a third-party parts list won’t show you the subtle casting changes. This Dynapac CA-25 Parts Catalog is the real deal – 298 pages of OEM data straight from the manufacturer. Use it.

Does this manual cover the hydrostatic pump assembly?

Yes, group E-3 and E-10 cover the main pump and the vibration pump with full part numbers.

How do I find the correct part number for the brake master cylinder?

Turn to group D-7 – Brake Master. The exploded view shows the cylinder body, pistons, springs, and reservoir. Each component has a callout corresponding to the parts list on the facing page. Match the casting number on your cylinder to the illustration – if it matches the series range on page 3, you’ve got the right part. If your machine is outside the serial block, you’ll need a different catalog. The manual also includes the emergency brake (D-9) and service brake (D-8) assemblies, so you can order all brake components from one source without mixing up the hardware.

For additional coverage options, check the DYNAPAC CA-25 Series 1987 Parts Catalog, the DYNAPAC CA-25/CA-25A/CA25S/CA-25D/CA-25PD Parts Manual, or the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec. If you need to verify manufacturer background, see Dynapac for official service bulletins. For context on heavy-equipment repair standards, read the Automotive Industry Overview.

You have the serial number, you have the broken part in your hand, and you need the right replacement now. Access the Factory Manual and get the OEM part number the first time.
