Dynapac CA 25 Parts Catalog

Ever had a job stalled because the part number you ordered didn’t match the assembly? I have. Aftermarket catalogs are guessing games dressed as books. This Dynapac CA 25 Parts Catalog is not a guess. It’s the original factory breakdown from Dynapac”>Dynapac – Svedala Dynapac LTDA out of Brazil. 157 pages of exploded diagrams, part numbers, and assembly sequences for the CA 25 vibratory roller with a Cummins 6BT5.9 diesel. If you’re turning wrenches on one of these, this is the only document you should trust for ordering spares. Period.

Chassis and Drum Cartridge Breakdown

You get exploded views for the left drum cartridge on two different configurations because the series numbers change. Watch that. The torque hub section (page 20) is critical – it covers the planetary reduction gear. If you’re rebuilding that hub, you need the part numbers for bearings, seals, and the torque specs for the output flange bolts. This catalog lists them. The steering link, scrapers, and roller assemblies are all broken out separately. No guessing which washer goes where.

Engine Group and Fuel System Components

Under the engine group, the catalog breaks down the Cummins 6BT5.9 diesel. Radiator assembly, exhaust cleaner, air cleaner. But the fuel system (page 12) is where you’ll spend your time. It shows the fuel tank, filters, injection pump, and lines. Part numbers for the governor linkage? They’re there. If you’re replacing the lift pump, the diagram includes the bracket and hard lines. Aftermarket catalogs often bundle these wrong. Not here.

Hydraulic Equipment – Drive and Vibration Systems

Group 005 covers the drive hydraulic system, hydrostatic pump and motor, vibration hydraulic system, steering, and direction valves. The hydrostatic motor appears three times in the catalog because there are different configurations for different series. If you’re servicing the vibration circuit, the catalog separates the vibration hydraulic system from the drive system. That matters when ordering seals and pistons. The hydraulic oil filter and gearing are also detailed.

That covers the hydraulic system.

3 Reasons to Trust the OEM Parts Catalog

First, this is not a reprint. It’s the original PDF from the factory – Automotive Industry Overview and construction equipment manufacturers like Dynapac put real engineers on these documents. Second, the exploded views show exactly how parts stack. You see the washer, then the nut, then the lock plate – not a blob with one number. Third, the part numbers are verified against the factory database. You cross-reference to the Dynapac CA 25 Parts Catalog”>Dynapac CA 25 Parts Catalog and you get the right piece.

Torque Specs and Assembly Callouts

A parts catalog isn’t a service manual, but it often includes torque callouts on the assembly drawings. This CA 25 catalog does that. The torque hub drawing (page 20) has a note with the flange bolt torque – 250 ft-lbs, if I recall correctly from the line drawing. (Don’t take my word – look at the page.) The hydraulic pump gearing section shows fastener grades. You need that when you’re bolting a pump back on. Never guess a torque on a vibratory roller. Loose hardware turns into a wrecked bearing.

Frequently Asked Questions

Is this a service manual or a parts catalog?

Parts catalog. It lists part numbers and exploded views, not repair steps.

Does it cover the Cummins engine in detail?

Yes. The engine group includes the radiator, fuel system, exhaust cleaner, and air cleaner assembly. The Cummins 6BT5.9 is shown with all its subcomponents – injection pump, turbo lines, oil cooler. You get part numbers for the block, head, and seals.

Will this help me order the correct torque hub bearings?

Absolutely. The torque hub section (page 20) has an exploded diagram that labels each bearing, seal, and shim. You can match the factory part numbers directly. But pay attention – the catalog notes different series numbers (CA25 from series 709B000 vs 710B500). If you order bearings without checking the series, you’ll get the wrong internal cage. The catalog lists the applicable series for each hub configuration. That’s the kind of detail you don’t get from aftermarket PDFs. Also, the torque specs for the output flange are called out on the drawing, so you can reassemble it to factory spec and avoid hub failure.

How do I use the catalog to find a part quickly?

Use the table of contents. Each group has a page number. For example, fuel system is on page 12, chassis on page 1. Then find the exploded view and read the reference numbers. Match them to the part number list on the opposite page. It’s straightforward once you get the layout.
