If you’re trying to order a replacement part for a Dynapac CC-50, CC-50A, or CC-50S vibratory compactor and you get the wrong number, you already know the headache. The machine sits. The job waits. And the dealer wants a serial number and a part number you don’t have. That’s exactly why this Dynapac CC-50A, CC-50, CC-50S 1982 Parts Catalog needs to be on your shop computer or tablet before you call your parts supplier.

This is an original OEM publication from Dynapac Mfg Inc., dated February 1982. It covers the CC-50, CC-50A, and CC-50S models with 183 pages of exploded parts diagrams, index numbers, and factory part numbers. You’re not getting a scanned aftermarket copy with missing pages or blurry illustrations. This is the real thing—the same book the dealer’s parts counter uses.

What This Parts Catalog Actually Covers

The table of contents lists every major assembly on the machine. You get sections for the Brake Assembly (pages 62-65), Electrical Wiring Diagrams (page 115 for CC-50), Engine & Pump Assembly (page 9), Fuel System (pages 15-16A), and the Valve assemblies including Manifold Valve and Vibration Control Valve. There are also detailed breakouts for the Drum Assembly (Fairfield and Staffa versions), Hydraulic Steering, Traction Motor, and the Water System. Each exploded view uses index numbers that match a parts list with the exact part number, description, and quantity per machine.

3 Systems That Require the Right Part Number

You can’t afford to guess on parts for the following systems because one wrong number means downtime and return shipping.

• Brake system – The Brake section (pages 62-65) shows the parking brake, service brake, and all seals. Use the wrong seal and you have a leak or no pressure.
• Engine and fuel system – The Fuel System (pages 15-16A) includes the tank, lines, filter, and pump. Ordering the wrong fuel filter mounting bracket is a waste of time.
• Hydraulic valve control – The Vibration Control Valve and the Manifold Valve Assembly have proprietary parts. The catalog identifies each spool, spring, and seal with a factory number.

Why OEM Parts Documentation Matters

Aftermarket parts catalogs often substitute generic part numbers or leave out supersession information. This Dynapac original has the exact part numbers that the manufacturer used when the machine was built. If a part was updated, the catalog shows it. The exploded views also give you the correct assembly order, which helps when you’re installing parts on a disassembled drum or pump drive. Dynapac CC-50A CC-50 CC-50S 1982 Parts Catalog – OEM Factory Specs is the benchmark; don’t settle for a third-party list.

Is This Manual Right for Your Dynapac Model?

This catalog specifically covers the CC-50A, CC-50, and CC-50S. The index at page 3 shows which page numbers apply to each model. For example, the Console Assembly is on pages 17-19 for the CC-50A, but pages 20-22 for the CC-50 and CC-50S. The Engine & Pump Assembly (page 9) and Drum Assembly pages are shared across all three. If you own a CC-50A, you get the correct information for that variant. If you have a CC-50 or CC-50S, the same catalog works. There is no separate book for each model—this one covers all three.

How to Use the Exploded Views and Index Numbers

Open the catalog to any assembly, then find the index number on the diagram. Look up that number in the parts list column. The description tells you the part name, and the quantity column shows how many you need per machine. Indented parts are subcomponents of the assembly above them. For seals, retainers, and bolts, the catalog gives you dimensions like “1-1/4” OD x 1” ID” so you can verify fit. This eliminates the guesswork when ordering from a dealer or online supplier like Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec (if you also work on that model).

The Electrical Wiring Diagrams section (page 115 for CC-50) is laid out in a schematic that traces each circuit. If you’re troubleshooting a no-start or a dead vibrator, the diagram shows connector locations and wire colors. No chasing ghosts with a test light.

Where to Find the Complete Part Number for Your Machine

Each parts list includes a part number column, usually 6 digits. When you order, give that number along with the machine serial. The catalog also lists “NSS” for not sold separately and “A/R” for as required quantities. For example, the Fwd/Rev & Vibration Control section has a linkage assembly with multiple retaining rings and pins; those have separate part numbers so you don’t have to buy a whole kit. Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer follows the same format if you need that reference.

If you’re new to reading OEM parts catalogs, the introduction (page i-iii) explains the terms: R.H. and L.H. are defined from the operator seat facing forward, with the engine behind. Bolts designated HH are hex head; HT means heat treated. This matters when you’re replacing a bolt on the Steering Cylinder or the Vibration Motor mount.

This catalog is not a service manual—it does not contain torque specs or repair procedures. It is a parts identification and ordering tool. Use it alongside a factory service manual for repair work. But when the parts counter wants a number, this is the document that gets you the right one the first time.

For background on how manufacturers structure such documentation, you can read about the Automotive Industry Overview on Wikipedia. Also, Dynapac itself (now part of Atlas Copco) Dynapac continues to support these older models, so having the original part numbers from 1982 helps when cross-referencing with current inventory.

Q1: Does this catalog include torque specifications for bolts?

No. This is a parts catalog, not a service manual. Torque values are not listed.

Q2: Can I use this to order parts for a 1983 CC-50A that has been modified with a different engine?

The catalog covers the original factory configuration. If the engine was swapped to a non-Dynapac unit, the Engine & Pump Assembly (page 9) won’t match. You’ll need to identify the replacement engine separately. However, for the chassis, brakes, hydraulic system, and drum, the OEM parts are valid assuming no modifications to those systems. Always verify the serial number against the catalog’s applicability.

Q3: How do I find a part number for the hydraulic steering filter?

Look under “Hydraulic Steering Filter Assy.” in the table of contents. The page numbers are 81-81A for all models. The exploded view shows the filter element and housing. Use the index number to get the correct part number.

Q4: Is this the same as the operator’s handbook?

No. The operator’s handbook covers daily operation and maintenance. This parts catalog is only for ordering replacement parts. They are two different documents.

Stop wasting time with mismatched parts from guesswork. Download the Factory Manual and keep it on your shop tablet or printed binder. When a drum seal starts leaking or a brake disc wears out, you’ll have the exact part number in seconds instead of calling a dealer and waiting.
