Dynapac CA25 1987 Parts Catalog – OEM Factory Spare Parts Manual

You got a Dynapac CA25 vibratory roller in the bay with a transmission leak. Before you start pulling the gear box, you need the exact part numbers. This 1987 Parts Catalog is the factory document – 318 pages of exploded views, reference numbers, and part tables. No aftermarket reprint, no skimp on details. If you’re ordering seals, bearings, or a torque hub assembly, you need this on the bench next to your tools.

Group 4 Transmission: Gear Box and Wheel Axle

This group takes up a solid chunk of the catalog. Inside you get the three-speed gear box (Funk and Renondin versions), disc brake for Renondin, wheel axle, planetary gearing, and differential carrier with brake. Every component is broken down by ref number. For example, page 73 (Section 4-2) shows the torque hub assembly – each bolt, washer, and seal listed with the OEM part number. You won’t be guessing which bearing race goes where.

What Engines Does This Parts Catalog Cover?

Group 3 Engine lists five powerplants: Caterpillar D-3208, Deutz F6L912, Detroit 3-53T, Detroit 4-53, and Cummins 6BT5.9. Each engine gets its own subsections for cooling system, air cleaner, fuel system, exhaust system, and hydraulic pump gearing. If you’re swapping a radiator or replacing a fan shroud, the part numbers are right there – no cross-referencing required. That’s factory data, not a generic approximation.

5 Engine Options Listed in Group 3

All five engines share the same group, but the parts tables separate them by column headers so you can pick the correct variant. The cooling system breakdown for the Caterpillar D-3208 is on a different page than the Detroit – Dynapac CA25 Parts Catalog – OEM Factory Spare Parts Manual is the same structure. If you own a CA25D or CA25R, check the drum section (Group 2) for torque hub and drum-specific parts. The catalog covers CA25, CA25R, CA25D, CA25PD.

Cooling System: Fan, Radiator, and Shroud Parts

The cooling system section within Group 3 lists every component for each engine option. For the Cummins 6BT5.9, you get the radiator, fan blade, pulley, and belt part numbers. The exploded drawing shows the belt routing – no more ordering the wrong length belt. Dynapac built these rollers tough, and the factory catalog is the only way to keep them that way.

Use the Numerical Register to Find Any Part

Flip to the back of the catalog – there’s a numerical register that lists every part number with a reference to the group and page where it appears. Need a specific seal for the Renondin disc brake? Look up the part number, and the register tells you exactly where to find it. This saves you from flipping through 318 pages blind. Dynapac CA25 1985 Parts Catalog follows the same group system if you need a different model year.

Who Needs This Manual?

If you’re a fleet mechanic, a shop owner, or a DIYer who maintains your own CA25, you need this catalog. The exploded views let you identify parts without having the machine torn down. Order the right seal the first time – no downtime waiting for wrong parts. Beginners will appreciate the clear group numbering and the index. Seasoned techs will trust the OEM sourcing. Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec is another heavy-equipment catalog worth having if you work with Dynapac pavers.

Torque specs aren’t in this parts catalog – that’s what the service manual is for. But knowing the correct part number for a torque hub seals ensures you don’t install the wrong seal and cause a leak. Use this parts catalog as your component bible.

Source Validity

This is a direct facsimile of the original factory document printed November 1987 by Dynapac Heavy Construction Equipment. Order number 498370. Not a third-party scan, not a cobbled-together PDF. The part numbers, quantities, and diagrams match what Dynapac shipped from the factory. If you’ve been burned by aftermarket catalogs that list superseded parts, you’ll appreciate the accuracy.

Does this include torque specifications?

No, this is a parts catalog, not a service manual. Torque values for bolts, hub nuts, and hydraulic fittings are in the factory service manual.

How are parts organized if I don’t know the part number?

Start with the list of contents on page 2. Find the group that matches your system (e.g., Group 4 for transmission). Each group opens with its own contents list showing section headings. The exploded drawing ref numbers are keyed to the parts tables. If you can identify the part visually, match the ref number to the table. The numerical register at the end lets you reverse-search if you have a part number from a previous order. For example, if you have a seal part number from an old invoice, look it up in the register and it directs you to the exact page and group.

You’ve got the machine. You’ve got the tools. Now get the right parts. Automotive Industry Overview isn’t relevant here – stick with factory documentation. Access the Factory Manual and get your CA25 back in service.
