Dynapac CC 421, CC 421C Parts Catalog – 210 Pages of Factory Part Numbers

I have seen too many rollers sit dead on a jobsite because some guy tried to order a hydraulic motor by guessing dimensions off the old one. That costs billable hours and eats your rental margin. The Dynapac CC 421, CC 421C Parts Catalog – 210 pages of factory exploded views and genuine part numbers – is the only document I would trust when you need to pull a drum bearing or source a starter for the Deutz F6L 912 or Cummins 6BT 5.9 engine. Dynapac shipped this catalog from their Karlskrona facility; it supersedes earlier issues S-10232-1, -2, and -3. That means the part numbers inside are current as of 1993 for CC 421 rollers from serial *58010211* and CC 421C from *58020421*.

Engine Group Breakdown: Deutz F6L 912 and Cummins 6BT 5.9

Page 30 covers the entire engine group – motor, mounting brackets, cooling system, fuel injection lines. If you need the cylinder head gasket part number for a Deutz, look there. The catalog doesn’t reprint the engine service manual, but it gives you the exact factory part numbers you hand to the parts counter. No cross-referencing a third-party catalog that may or may not have updated supercessions. For the electrical equipment group, page 60 lists every sensor, switch, and wiring harness connector. Want the correct alternator for the CC 421C? It is in the 60-group with the Dynapac part number.

7 Major Groups in This Parts Catalog

The manual splits the machine into logical groups:
Frame (group 10) – articulation hitch, steering cylinders, frame weldments.
Drum (group 20) – vibration system, drum shells, bearings, scrapers.
Engine (group 30) – as described above.
Hydraulic system (group 50) – pumps, valves, motors, hoses.
Electrical equipment (group 60) – wiring, lights, gauges, control modules.
Drivers platform (group 70) – seat, ROPS, controls.
Decals, standard equipment, optional equipment (groups 80, 90, 91) – safety labels, standard hardware, extra items like sprinkler kits.

Each group shows an exploded diagram with callout numbers. The part number index on page 100 lists every number alphabetically so you can cross-check.

Real-Use Scenario: Rebuilding a Drum Bearing on a CC 421

You pull the drum end cap. You find the old bearing has no visible number. Without this catalog, you might call Dynapac with a serial number and wait. With the catalog, you flip to group 20, find the drum assembly diagram, read the callout, and get the factory part number from the adjacent table. You order exactly that bearing. One trip to the parts store. That is the difference between a morning job and a two-day down machine. Dynapac CC 421, CC 421C Parts Catalog – OEM Factory Specs is the same document I keep in the shop binder.

Why OEM Beats Aftermarket Parts Catalogs

I have seen aftermarket catalogs that list a generic hydraulic filter that is 2 inches too short. That filter bypasses under high pressure and sends debris into the pump. This catalog came from Svedala Dynapac – the people who built the roller. Every part number has been validated against the actual machine. The catalog even notes which issue number applies to which serial range (page 3). If your roller serial falls outside the range, you might need a supplement. For the vast majority of CC 421 and CC 421C rollers built after 1993, this is the correct parts reference.

Does This Catalog Include Service Procedures?

No – this is a parts catalog, not a service manual. It will not tell you how to rebuild a hydraulic pump or what torque to set the drum mounting bolts. If you need repair instructions, look for the corresponding workshop manual. But for ordering parts, this is the only source that guarantees the number you write down matches what Dynapac shipped from the factory. Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec and Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer follow the same format for other Dynapac machines.

FAQ: Four Questions You Might Have

What models are covered by this parts catalog?

Dynapac CC 421 and CC 421C vibratory/combination rollers with the specified serial number ranges. See page 3 for exact validity.

Does this manual list torque specs for frame bolts?

No. This is a parts catalog – it shows exploded views with part numbers, not torque values. Use the service manual for assembly torques.

How many pages is the catalog and what format is it?

210 pages, PDF. The original file name is Dynapac_CC_421-CC_421C_Parts_Catalog_en-26114002645.pdf. This is a direct scan of the factory printed manual, so the diagrams are clear and the text is sharp.

Can I use this to identify a part on my CC 421 that has a different engine?

The catalog covers both Deutz F6L 912 and Cummins 6BT 5.9 options. If your roller was built with a different engine (e.g., an alternative spec), the engine group may not apply. Check your roller serial number against the table on page 3 to confirm the catalog issue matches your machine.

If you maintain a fleet of Dynapac rollers or own a single CC 421C, this catalog saves you from guessing part numbers off worn-out components. Automotive Industry Overview is a whole different world – but in compaction equipment, correct part numbers keep the roller rolling.
