Dynapac CC122, CC122C 2011 Parts Catalog

If you have ever ordered a hydraulic motor for a Dynapac CC122, CC122C 2011 Parts Catalog and got the wrong flange pattern, you know exactly why this manual exists. I have seen guys guess based on a worn-out tag, wait two weeks for shipping, then find out the shaft key is wrong. That is lost billable hours and a roller sitting dead. Dynapac built two variants—the CC122 and CC122C—and they share a lot, but the part numbers change depending on serial number break points. This is the OEM catalog, 228 pages, published in 2011, and it covers rollers from serial number 10000308x0A000001 onward.

Get the Right Part Numbers the First Time

Every time you open a third-party parts list, you risk getting a superseded number or a cross-reference that never existed. This catalog comes straight from Dynapac (then part of the Atlas Copco group), with the same exploded views and item callouts their own dealers use. The first few pages show exactly how to order: give machine type, roller serial number, quantity, part number, denomination, and dimensions if it’s a length item. That six-point checklist on page 2 is not optional—skip it and you get wrong parts.

Service Kits and Repair Kits: Pre-Assembled Groups

Deutz D2011 L02 I engine is the heart of these rollers, and Dynapac bundled the routine maintenance into three service kits. Part 4700938542 covers the 50-hour service, 4700938543 the 500-hour, 4700938544 the 1000-hour. The catalog breaks them down with individual part numbers inside each kit. If you are rebuilding an eccentric shaft, order repair kit 4700938908 rather than sourcing bearings separately—it includes the seals and shims the factory spec demands. Same logic for the drum rotation kit (4700938892) and scraper kit (12u202fmm, 4700938914). Those kits save you from hunting down ten separate numbers.

Hydraulic System: Propulsion, Steering, Vibration

The hydraulic section covers the propulsion pump (4700372352), drum motors for CC122 and CC122C (4700390742, 4700375631, 4700375632), and the steering valve (4700902099) and cylinder (4700374603). If you are replacing a junction block, the number is 4812110281. Each component has an exploded diagram with callouts. Compare that to a generic parts site that lists one pump for “all compactors.” One wrong mounting flange and the whole job stops. This catalog gives you the exact revision level that matches your machine serial number.

Does This Manual Cover Optional Equipment?

Yes, and the optional-equipment section is where most aftermarket lists fail. Dynapac offered a canopy, SMV-sign, noise suppression kits (78u202fdB and 73u202fdB), back-up alarm, rear mirror, combination water supply with two rear sprinkler pipes, towing valve, flow divider, vibration shut-off for front drum, automatic vibration control, service brake, driving restriction, bio-hydraulic oil lock, and brake release for the Poclain motor. Each option has its own exploded view and part numbers. If you need the wiring for the interlock system, there are three variants listed: standard, Loxam, and Positive. No guessing which one fits your roller—find the option section, match your serial number break, and order.

Why Factory Serial Number Range Matters

The front of the catalog states “Valid from roller serial number: 10000308x0A000001 -”. The “x” represents a wildcard digit because Dynapac used a check digit system. If your CC122C has a serial number below that range, you need an earlier issue (SCC122C-4EN1 from 2010). This is the second edition, SCC122C-4EN2, dated 2011. Ordering parts from the wrong revision can get you a different steering hitch or a drum motor with a different displacement. I have seen it happen: a shop buys a scraper kit for a newer machine and the bolts don’t line up. Always check the serial number plate before you start ordering.

FAQ

Can I use this catalog for a CC122C with serial number below 10000308x0A000001?

No. You need the earlier edition SCC122C-4EN1 from 2010.

What information do I need to order a part using this manual?

Six pieces: machine type, roller serial number, quantity, part number, part denomination, plus dimensions if ordering by length. Page 2 lists them in English, Swedish, German, Italian, Spanish, and French. The dealer will reject your order if any field is missing.

Are torque specs included in a parts catalog?

No—this is a parts catalog, not a service manual. Torque values belong in the shop manual. This book only gives part numbers and exploded views.

Does this manual include wiring diagrams?

It includes electrical component locations (control panel, battery switch, interlock, lights, beacon) but not full wiring schematics. For wiring trouble, get the Dynapac electrical diagram manual.

This is the factory spec, not a reprint or a scan that lost resolution on the callout numbers. 228 pages, every part number verified against the 2011 Dynapac master database. If you are maintaining a CC122 or CC122C, you need this book open on the bench while you break down the drum.
