Dynapac CP221 Parts Catalog – OEM Factory Breakdown for Roller Maintenance

If you are working on a Dynapac CP221 Parts Catalog roller, you already know the frustration of trying to cross-reference a worn brake chamber or a leaking hydraulic hose without the original part numbers. Aftermarket catalogs often skip the details that matter – like the exact DANA transmission shaft or the Meritor differential components. This OEM Parts Catalog from Dynapac gives you 206 pages of factory-sourced breakdowns. Every component is listed with Dynapac’s own part numbers, so you order the right piece the first time. I’ve spent 28 years in this trade, and I can tell you the difference between a job done with OEM documentation and one done with a generic PDF. This is the real deal.

What’s Inside the Dynapac CP221 Parts Catalog

This manual covers the entire machine from frame to tool equipment. The table of contents lists 12 major groups: Frame, Suspension, Engine and transmission, Pneumatic equipments, Hydraulic system, Steering system, Electrical equipment, Drivers platform, Decals, Standard equipment, Optional equipment, and Tool equipment. Each group is further broken down into sub-assemblies with exploded views and part number tables. Need to find the brake valve for the pneumatic circuit? The catalog groups it under Pneumatic equipments, with separate entries for the Knorr-Bremse LP4 compressor and the brake chamber. That kind of granularity cuts your search time.

Suspension and Brake: Finding the Right Part Numbers

The suspension section (page 26) includes steering link, front and rear suspension, and the 259219 Brake assembly. If you’re replacing a wheel or tyre, the catalog gives you options for Bridgestone, Michelin, Firestone, and Pirelli – each with its own part number and quantity. For the brake side, you get the master cylinder repair kit (939497) and the brake chamber (384571). That level of detail is why you don’t want to rely on a third-party list. I’ve seen too many shops order the wrong brake chamber because the aftermarket catalog lumped all models together. This catalog calls out the exact serial number range (CP221 FROM PN 2262BR2117).

Engine and Transmission: Cummins and DANA T20000 Coverage

Page 50 kicks off the engine and transmission section. The Cummins engine breakdown covers cooling system, fuel system, muffler, and air cleaner. But the real meat is the DANA T20000 transmission. The catalog devotes 20 pages to the transmission alone – from the converter housing (page 64) to the control valve assembly (page 92). If you need the charging pump and filter, it’s on page 94. The forward shaft, reverse and 2nd shaft, low speed shaft – all listed with part numbers and quantities. For a transmission rebuild, this is the blueprint you want on your workbench, not some reprinted generic diagram.

Why an OEM Parts Catalog Beats Aftermarket Versions

Aftermarket parts catalogs often use scanned images that are blurry or missing callouts. Worse, they sometimes substitute part numbers from different model years. This Dynapac factory catalog was produced by Dynapac Compaction Equipment AB, the original manufacturer. Every page is clean, every part number matches the engineering drawings. The table of contents is numbered and cross-referenced. You get the same information that a Dynapac dealer uses. When you’re ordering a $600 brake chamber or a $1,200 transmission shaft, you want the part number to be correct. This catalog gives you that certainty.

Who Should Use This Manual?

If you own a Dynapac CP221 roller, you need this catalog. It’s also useful for shop mechanics who maintain a fleet of compaction equipment. The illustrated parts breakdown makes it easy to identify wear items – blade scrapers, sprinkler system components, and the canopy hardware. Even if you’re a DIYer who bought a used CP221 at auction, this catalog will help you source the right parts to get it running. I wouldn’t attempt a transmission overhaul without it. The DANA T20000 has a lot of internal parts that look similar but have different part numbers. One wrong gear can cost you days of downtime.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This catalog contains part numbers only. Torque specs require the service manual.

Can I use this to order parts online?

Yes. Each part number listed is the original Dynapac reference. Give those numbers to your local dealer or online parts supplier. The brake chamber 384571, for example, is cross-referenced directly. You also get the quantity needed per assembly, so you order exactly what’s required. I’ve seen people order two when they only need one – this catalog prevents that mistake. Additionally, the exploded views show the relationship between parts, helping you identify if a seal or gasket is included. For the DANA transmission, you can see exactly which shaft and gear go together. This reduces the risk of ordering incompatible components.
