Dynapac CP221 Parts Catalog

You need a replacement hydraulic hose for the CP221. You call the dealer, they ask for a part number. You don’t have it. So you guess, order the wrong one, and the roller sits for a week. That’s the pain this catalog kills. It’s the official Dynapac CP221 Parts Catalog from the factory—291 pages of exploded views, part numbers, and ordering specifications. No reprints, no aftermarket guesses. Just what the assembly line used.

291 Pages of Factory-Approved Part Data

This isn’t a service manual. It’s a parts catalog. Every page breaks down a subassembly—brake system, steering, hydraulics, engine—into numbered components. You get the part number, description, quantity, and often a dimensional note. Page 4 shows the six fields Dynapac requires when ordering: machine type, serial number, quantity, part number, denomination, and dimensions for meter goods. Skip one of those and the wrong part shows up.

Engine Identification: Cummins 4BT 3.9C and Elite Variants

The CP221 rolled off the line with two engine options—Cummins 4BT 3.9C and the 4BT 3.9C Elite. The catalog lists separate part groups for each. You need to know which serial number range your roller falls into. The front matter shows that from serial *22620278* through *22620599* you get the Elite. Outside that, standard. One wrong oil filter part number and you’re chasing leaks.

Serial Number Cross-Reference: Why It Matters

Page 3 lists the catalogue issue history: SCP221-2EN1 through SCP221-2EN5. Each issue updated parts based on production changes. If you use a later issue on an early roller, you might order a bracket that doesn’t fit. The catalog tells you which issue matches your serial. Don’t ignore it. I’ve seen guys order a steering cylinder from the wrong revision and spend a day making it fit with a grinder.

How This OEM Catalog Beats Aftermarket Lists

Aftermarket parts lists are often scanned from old copies or compiled from memory. This is a direct PDF of the Dynapac-printed original. The exploded diagrams are crisp. The part numbers match factory inventory. When you call a Dynapac dealer and read off a number from this catalog, they ship the right thing. No cross-referencing needed. Compare that to a forum thread where some guy says “this hose from a Case backhoe fits.”

Ordering Spare Parts: The 6 Required Fields

Page 4 spells it out in five languages. You give them: machine type (CP221), roller serial number, quantity, part number, part name, and dimensions if ordering by length. Miss the serial number and you might get a part for a different revision. I keep a copy of page 4 taped to my toolbox. It saves phone calls.

What This Catalog Won’t Give You

Torque specs, repair procedures, hydraulic pressures—none of that is here. It’s a parts catalog, not a service manual. If you’re rebuilding the transmission, you need the service manual. But if you’re ordering the transmission gasket kit, this catalog gives you the part number. That’s its job.

One more thing: the Automotive Industry Overview includes standards for parts numbering that Dynapac follows. This catalog uses those standards. You’ll recognize the logic if you’ve worked with OEM documentation before.

FAQ – Two Questions About This Catalog

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values are not listed. You need the service manual for that.

How do I find the correct part number for my CP221?

First, locate your roller serial number on the machine plate. Then cross-reference the serial number against the catalogue issue table on page 3. That tells you which part version is correct. Next, find the assembly group in the catalog (engine, hydraulics, etc.) and look up the exploded view. The part number is right next to the callout. If the part is a length item like a hose, measure the old one—the catalog may list dimensions. Then order using the six fields from page 4. This process eliminates the 30% error rate you get from guessing part numbers based on a photo.
