Dynapac CA 25, CA 25D, CA 25PD, CA 25R Parts Catalog

If you’ve ever tried to order a part for a Dynapac CA 25 series roller without a parts catalog, you know the drill: you cross your fingers on the part number, wait two weeks, and then find out the hydraulic motor seal you got doesn’t match the Staffa drive unit on your machine. That wasted billable time and the return shipping eats into your margin. I’ve been turning wrenches long enough to know that guessing on parts is a leak in the bottom line. This factory Parts Catalog for the CA 25, CA 25D, CA 25PD, and CA 25R models kills that guesswork. It’s the same binder Dynapac handed their dealers. 322 pages of exploded views, reference numbers, and the exact part names – no reprints, no third-party redraws.

This is the OEM document originally printed by Dynapac Heavy Equipment AB in Karlskrona, Sweden. The publication number S-10055-3 replaces earlier editions. Every group in the table of contents lines up with a physical section of the machine: frame, drum, engine, transmission, hydraulic system, electrical equipment, driver’s platform, decals, and equipment. You get the same information the factory used to stock their service vans.

Frame and Drum Coverage – Group 1 and Group 2

Start at the ground. Group 1 covers the frame (RAM) including the tractor upper section, engine hood and radiator stand specific to the Deutz F6L 912, scrapers, and steering link. Group 2 breaks down the drum – the vibrating component that does the compaction. You get separate exploded diagrams for the CA 25 standard drum versus the CA25D/PD with the Staffa drive unit and the Fairfield drive unit. The torque hub (Fairfield) is detailed with all internal seals and planetary gears. If you’re rebuilding the drum end, you need this section to order the correct bearing and shaft seals.

Engine Groups – Caterpillar and Deutz

Three engine options appear in Group 3: Caterpillar D-3145, Caterpillar D-3208, and Deutz F6L 912. Each has its own subsection showing the engine assembly, radiator and oil cooler, air cleaner, and fuel system. Hydraulic pump gearing is listed for Funk, Renondin, Prometheus, and Dynapac housings. Don’t assume a Cat D-3208 used in a forklift shares the same water pump – the roller’s mounting bracket and fan location are different. The parts picture makes it obvious.

Transmission and Hydraulic System – What You’ll Actually Need

Group 4 shows the three-speed gearbox (Funk or Renondin) including disc brake components, wheel axle, differential carrier, and planetary gearing. The torque values for fasteners are not listed in a spec table here – this is a parts catalog, not a repair manual – but the exploded views show every bolt, washer, and locknut individually. If you need to know what grade of hardware goes into the Renondin disc brake, the part number will lead you to the right fastener. Group 5 dives deep into the hydraulic system: propulsion circuit, drum drive (CA25D/PD), variable displacement pump, charge pump, control valves, steering cylinder, and all hoses. The hydraulic diagram on page 2 of that group is critical for troubleshooting circuit flow. Without it, you’re shooting parts at a symptom.

Electrical, Platform, Decals – Why 322 Pages Matter

Group 6 covers the electrical equipment for Caterpillar and Deutz harnesses. Group 7 details the driver’s platform: instruments, vibration controls, brake and gear shifter, foot brake, throttle, and forward-reverse control cables. Group 8 shows every plate and decal – if a safety decal peels off, you can order the correct part. Group 9 lists the standard tools and equipment that came with the machine. That extra 10mm socket you found in the toolbox? It’s listed as a factory item. All 322 pages are organized by groups and picture numbers, so you can walk up to the parts counter with a page reference like “Group 2, picture 11009-2” and get the right part the first time.

Source Validity – Why OEM Beats Aftermarket

I’ve had aftermarket parts catalogs that list a hydraulic pump as “fits CA25″ but the displacement is wrong because the original Dynapac pump had a different bolt pattern for the Renondin adapter. This catalog eliminates that risk. It’s the factory scan – same page numbers, same Swedish/English headers, same exploded views that Dynapac published. You can cross-check the part number with Dynapac directly or compare with the Automotive Industry Overview perspective on standardization, but the real trust comes from holding the page that matches the machine’s serial number range. This is not a reprint; it’s the original document.

Need to confirm which drive unit your CA25D/PD carries? The Staffa and Fairfield options are clearly separated. Want to know the part number for the charge pump on the propulsion variable displacement pump? Look at the “Charge pump” subheading in Group 5. The page number reference is in the table of contents. Compare with related manuals like Dynapac CA 25 Parts Catalog or the Dynapac CA 25 Spare Parts Catalogue for other models. For specific Caterpillar 3208 engine parts, the Dynapac CA 25, 25D, 25PD, 25R, 3208 Parts Catalog OEM is the one you want.

Who Needs This Catalog and How to Use It

If you own or maintain one of these rollers – or work at a shop that services them – you’re the audience. A home garage enthusiast might not be rebuilding a compactor, but a fleet mechanic or an equipment dealer sure will. Use the catalog to pull part numbers before opening a repair job. When you have the roller disassembled, lay the exploded view next to the bench and tag each component. It beats taking photos and squinting at a phone screen. For torque specs on the drum or axle fasteners, you’ll need the separate repair manual – this catalog doesn’t have tightening sequences. But for ordering, it’s the only source.

Frequently Asked Questions

Does this manual cover the CA 25R model?

Yes. The catalog explicitly lists CA 25, CA 25D, CA 25PD, and CA 25R on the cover and throughout the group headers. Every section applies to all four.

Will this help me rebuild the Fairfield torque hub?

It will show you every part inside the torque hub – bearings, seals, planetary gears – with part numbers. For assembly torque values, you need the separate service manual.

What engines are in the catalog?

Caterpillar D-3145, D-3208, and Deutz F6L 912. Each has dedicated subsections in Group 3 with separate fuel, cooling, and air cleaner pages.

Is the hydraulic system diagram detailed enough to trace a pressure loss?

Group 5 starts with a hydraulic diagram on page 2. It shows the flow path for propulsion and drum drive circuits, but it is a parts-identification diagram, not a service troubleshooting schematic. You will see every valve and hose listed, but you cannot read pressures from it. For diagnostics, pair this with the OEM service manual.

This parts catalog belongs on the shelf next to the service jack for any Dynapac CA 25 series roller. The 322 pages give you the factory’s own part numbers so you stop wasting time on returns and wrong fits. When you are ready to order a new hydraulic pump or a decal kit, you open to the right page, note the reference number, and call the dealer. Access the Factory Manual from AutoRepairManuals – it’s the digital file, searchable, and printable. No DRM, no restrictions. Just the OEM data you need.
