Dynapac CP221 Parts Catalog – 331 Pages of OEM Spare Parts Documentation

If you’ve ever ordered a replacement bushing for a pneumatic tire roller only to get the wrong diameter, you know the cost of a bad part number. That’s lost time, a machine down, and another week waiting. The Dynapac CP221 Parts Catalog stops that. 331 pages of factory-sourced exploded diagrams and parts lists. This is the document the Dynapac dealer uses when you call in a serial number. It’s not a reprint or a generic scan – it’s the original issue from Dynapac themselves, with publication index SCP221-1EN4 covering serial number ranges from 1998 through 2004.

Ordering Spare Parts: The 6 Required Data Points

Page 4 of the catalog dedicates a full section to ordering procedures. You need six pieces of information: machine type, roller serial number, quantity, part number, denomination, and dimensions when ordering per length. Skip any one of those and your dealer will probably ship the wrong item. Experienced mechanics know that writing down the roller serial number before you call is half the battle. That number ties every part to the exact production batch of your CP221.

Every section in this catalog groups parts by function – engine, drivetrain, hydraulic system, rollers, brakes, electrical, and frame. Each group has its own page index, so you flip directly to the exploded view instead of hunting through 331 pages blind. You pair the part number from the diagram with the table below it, verify the supersession notes, and place the order. It’s one of those workflows that looks slow the first time but saves you hours once you learn the group numbering.

Does This Catalog Cover the Cummins Engine Variants?

Yes, it covers both the CUMMINS 4BT 3.9C and the CUMMINS 4BT 3.9C Elite. The catalog lists the applicable serial number range – 22620221 through 22620277 – and matches each variant to the correct fuel system, turbo, and gasket sets. If you’re rebuilding the injection pump or replacing a cylinder head, you need the exact engine version. The parts catalog gives you the right part numbers for both standard and Elite builds, with clear callouts for differences in the lubrication and cooling groups.

Don’t trust aftermarket parts lists for engine internals on a roller that runs 10‑12 hours a day. One wrong piston ring profile and you’ll be pulling the head again inside 200 hours. Stick with the OEM part numbers from this catalog.

Roller Serial Number Cross-Reference

OEM documentation ties every part revision to a specific serial number break. Page 3 of the catalog shows the full revision history: SCP221EN1 (1998) replaced by SCP221EN2 (1999), then three further revisions until SCP221-1EN4 (2004). If your CP221 was built in 2003, you need the SCP221-1EN3 issue. The catalog you’re looking at is SCP221-1EN4, which is the final revision superseding all earlier versions. It covers both serial number ranges and all cumulative engineering changes. That means if you own a machine from any production year, this single document contains every part number you’ll need – no hunting for outdated bulletins.

3 Reasons an OEM Parts Catalog Beats Third-Party Lists

First, accuracy of dimensions. Third-party lists often transpose metric and imperial measurements on bushing diameters and hose lengths. One mistake and the part doesn’t fit. Second, supersession tracking. OEM catalogs flag when a part number has been replaced by a new revision – something generic lists ignore. Third, diagram clarity. The exploded views in this catalog show every washer, seal, and retaining ring in its correct position. You see the assembly order, which helps if you’re taking something apart and need to know the stack‑up sequence.

For reference, pair this catalog with the Dynapac CP221 Spare Parts Catalog for cross‑verification of part numbers across different publication indices. If you maintain a fleet, the Dynapac CP221 Parts Catalog is the master document every shop should have on the bench. For the smaller PL2000LS roller, see the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec.

Parts Catalog Structure – Group and Page Index

The catalog is organized by functional groups, each starting with a title page and a list of component illustrations. Groups cover engine (Cummins), transmission, final drive, steering, hydraulic pump, roller suspension, water system (for ballast), brakes, electrical, and frame. Each illustration has a parts table with item number, part number, description, quantity, and notes. The notes column flags special items like lock washers or parts that require selective fit. If you need to identify a part from a worn‑out label, you match the visual shape in the drawing to the item number, then cross‑reference the part number table. It’s the same system the dealer’s parts counter uses.

Frequently Asked Questions

Does this catalog include torque specifications or repair procedures?

No – it is a parts catalog, not a service manual. It lists part numbers, quantities, and exploded views. For torque values and repair steps, you need the separate Dynapac CP221 Workshop Manual.

What engine models are covered in this catalog?

It covers the CUMMINS 4BT 3.9C and CUMMINS 4BT 3.9C Elite diesel engines. Both are included with detailed parts breakdowns for fuel system, cooling, lubrication, and cylinder head. The catalog identifies the exact serial number range for each variant – 22620221 to 22620277. If your roller has a different engine, this catalog will not apply. Always verify the engine model and serial number against the catalog’s coverage notes before ordering parts.

How do I find a part number if I only have the old part?

Match the physical shape and location of the old part to the exploded diagram in the correct group. Use the group index at the beginning of each section to narrow down the area. Then find the item number in the illustration and read the corresponding part number from the table.

Can I use this catalog for a CP221 built after 2004?

This issue (SCP221-1EN4) covers production up to the 2004 model year. Later machines may have engineering changes not reflected here. Check the serial number on your roller against the range listed on page 3. If it falls outside, contact Dynapac for the latest revision.

You need a parts catalog that puts the exact OEM numbers in your hand, not a blurry scan from some forum. This document is the one Dynapac publishes for its own dealers. 331 pages, factory diagrams, real part numbers. Stop guessing which bushing fits. Access the Factory Manual and get the right parts the first time.
