Dynapac CP 221 Parts Catalog – Stop Guessing, Start Ordering the Right Parts

If you’ve ever wrapped a roller up for a week because you ordered the wrong transmission seal or fuel injector line, you already know the pain this catalog solves. I’m Mike Callahan – been torquing bolts since most of you were in grade school. When I see a guy trying to cross-reference a Dynapac part number off a third-party website, I know he’s about to waste his weekend. This is the Dynapac CP 221 Parts Catalog, not a chiltons rip-off. 437 pages of factory-original exploded diagrams and part numbers for the pneumatic tired roller with the Cummins 4BT 3.9 diesel engine. No guesswork. No “maybe this fits.”

Every component group is indexed – frame, cover, seat, scrapers, transmission, engine, radiator, fuel system, air cleaner. Need the exact part number for a radiator hose? You’ll find it in the Radiator assembly section. Need the transmission overhaul kit number? It’s in one of the seven transmission pages. This catalog comes straight from the Svedala Dynapac plant in Sorocaba, Brazil. It covers serial number ranges 696B300-, 705B200-, 705B300-. If your CP 221 falls in those, this is the only book you should trust for parts.

Engine and Transmission Breakdown

The catalog dedicates multiple pages to the Transmission and Engine – starting at page 002 and running through page 038. The Transmission section alone spans eight separate pages (022, 026, 028, 030, 034, 036, 038). Each exploded view is keyed to a parts list with Dynapac’s own reference numbers. If you’re rebuilding the axle or swapping the pump, you’ll see exactly which shim, seal, or gear goes where. The Engine section covers the Cummins 4BT 3.9 – fuel injectors, turbo lines, block components. Don’t trust any aftermarket interchange list for that. Use the factory diagram.

For example: the Fuel system is on page 012. It shows the entire fuel line routing, from tank to injector pump, with separate part numbers for each hose clamp and fitting. I’ve seen guys buy a “universal” fuel line kit and then spend half a day making it fit. Not necessary. One page, correct numbers.

437 Pages of Factory Part Numbers

Four hundred and thirty-seven pages. That’s not a reprint. That’s the full OEM catalog, scanned from the original print. Every page is numbered – the TOC starts with GENERAL VIEW on page 000, then Frame (001), Cover and frame (002), Seat ass’y (008), Rear cover (010), Front scrapers (014), Rear scrapers (018), Transmission and engine (002, again for the detail pages), Radiator assembly (006), Fuel system (012), Air cleaner assembly (018), and then the eight Transmission pages. Each group has its own illustration number – for example, the general view is Fig. DC01613-2. That level of detail is what lets you walk up to a Dynapac dealer and hand them the exact part number for your year and series. No “it should be this one.”

Fuel System: Finding the Right Component

Diesel fuel systems on these rollers are picky. The CP 221 uses a Cummins 4BT 3.9 with a Bosch-type injection pump. The Fuel system page (page 012) breaks down every component: the water separator, the feed pump, the high-pressure lines, the return lines, the injectors themselves. Each item has a Dynapac part code. If you need a new injector nozzle, you get the number. If you need the banjo bolt for the fuel return, you get the number. No measuring, no “I think this thread is M10.” This is the kind of documentation that keeps a roller running in a fleet instead of sitting in the yard waiting for the wrong part to arrive.

And yes – this catalog is in English, Spanish, French, and Portuguese. The TOC and headers are multi-lingual. So whether you’re in Texas or São Paulo, you can read it.

Use the Parts Catalog Like a Pro

Don’t treat this as a PDF you open once. Print the pages you need for the job. Lay them next to the exploded diagram. Cross off each part as you pull it off the shelf. If you’re ordering, have the part number ready – don’t guess. A wrong part costs you shipping time and downtime. The Automotive Industry Overview shows how standardized parts catalogs save hours per repair; this Dynapac book is no different. Automotive Industry Overview

Yes, it includes English, Spanish, French, Portuguese.

Does this catalog cover the entire CP 221 roller?

It covers frame, cover, seat, rear cover, front and rear scrapers, transmission and engine (including the Cummins 4BT 3.9 diesel), radiator, fuel system, and air cleaner assembly. Each group is illustrated with exploded views and has its own part number list. The catalog references serial number ranges 696B300-, 705B200-, and 705B300-. If your CP 221 falls in those, you have the correct book. The Transmission section alone has eight detailed pages. This is the official Dynapac document, not a compilation.

If you’re working on a CP 221, don’t run your shop on memory or aftermarket cross-reference sheets. I’ve seen too many calls from guys who thought they could eyeball a part. Get the real thing. Access the Factory Manual and keep it on your tablet or laptop. One correct part number pays for the whole catalog.
