Dynapac CC 21 Parts Catalog

You’ve got a Dynapac CC 21 Parts Catalog sitting in front of you, and you need to order a part — not some generic cross‑reference that might be close enough. Close enough gets you a machine down and a customer waiting. This catalog is the factory print, 214 pages, organized by assembly groups so you don’t flip through scanning blurry aftermarket drawings. I’ve seen too many hacks try to eyeball a part number off a worn casting. That costs hours and money. This catalog fixes that.

Engine Section: Perkins vs John Deere

Take Group 03 – Engine. The catalog breaks it down by engine manufacturer: Perkins diesel and John Deere diesel. Two different mounting packages, two different part streams. You pull the wrong injection pump because someone said “they’re the same” and you’ll be pulling it back out. The catalog lists each assembly with OEM numbers. Page 2 of the engine group shows the Perkins mounting layout. No interpretation needed. You look up the reference number, order the exact piece.

214 Pages of OEM Part Numbers – Group by Group

Frames (Group 01), Chassis and platform covers, Steering link, Safety locking mechanism, Front and rear water sprinkler systems, Drum assembly, Brake, Torque hub, Scrapers. Every major system gets its own group with an exploded view and a parts list. The safety locki group on page 12 is critical — if you’re replacing that linkage, you need the right pin and spring. Aftermarket catalogs often skip the spring rate spec. This one gives you the factory reference.

Rear water sprinkler components show up on page 20. If your roller’s sprinkler system is dribbling instead of spraying, you can find the exact nozzle and valve part numbers without pulling the entire tank. That’s what this catalog is built for: pinpoint accuracy so you don’t buy parts twice.

How to Read the Group Numbers

Each section numbers the group and the page. For example, group 02 – Drum starts on page 02, then sub‑groups like Brake (page 10), Torque hub (page 14), Scrapers (page 20). The table of contents is printed in four languages: English, Portuguese, French, Spanish. If you’re working in a multi‑lingual shop, that saves translation headaches. The page references are identical across languages — you can hand this to any tech and they’ll find the same exploded view.

Torque Hub and Brake Assembly – When Specs Matter

The torque hub reducer and brake group (Group 02, pages 14 and 10) are areas where reusing a bolt or guessing the internal seal size will wreck your afternoon. This catalog shows the complete hub assembly with every bearing, seal, and retaining ring. You won’t find torque values in a parts catalog — that’s the service manual’s job — but you’ll get the correct part numbers to order the overhaul kit. Pair this with the Dynapac CC 21 Parts Catalog for the repair procedures. Or if you need the full breakdown for a different Dynapac model, check the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec.

Source Authenticity – OEM vs Aftermarket

I’ve wasted time on reprints that list a “compatible” part that doesn’t fit. This catalog is an original factory scan, printed by Dynapac themselves. The part numbers match what the dealer uses. No third‑party editor decided to “improve” the drawing. The group numbering, the reference columns, the exploded views — all identical to what you’d get if you walked into a Dynapac dealer and asked for the paper manual. That’s the difference between a job that goes together and one that fights you.

Does this catalog include wiring diagrams or service procedures?

No. It’s a parts catalog — exploded views and part numbers only. You need the service manual for procedures.

Can I use this to order parts for a CC 21 with a Perkins engine if my machine has a John Deere?

Both engine variations are covered in the same catalog. Group 03 splits into two sub‑groups: one for Perkins, one for John Deere. Make sure you use the correct reference column when ordering. The catalog lists the starting serial number ranges on page 3: 720055- and 730058-. If your machine falls outside those ranges, call Dynapac to verify before ordering. Do not assume cross‑compatibility — the mounting brackets and accessory drive parts differ between the two engines. The front water sprinkler group, steering link, and chassis components are identical regardless of engine choice, but the torque hub and brake assemblies depend on the drum configuration, not the engine. Always verify with the serial number reference on page 3 before you write up a parts order.

If you’re tired of fighting aftermarket catalogs that leave you guessing, get the factory data. The Dynapac CC 21 Parts Catalog – 240 Pages OEM is the same as this one (214 pages, the 240 is a typo in that listing — we’ve checked). For a different Dynapac roller, the Automotive Industry Overview doesn’t apply here, but the principle does: real factory specs save real time. Access the Factory Manual.
