Dynapac CC-50A, CC-50, CC-50S 1982 Parts Catalog

If you’re maintaining a Dynapac CC-50, CC-50A, or CC-50S vibratory compactor, you already know that guessing part numbers costs you downtime. I’ve seen guys order the wrong brake seal three times because they used an aftermarket cross-reference. This 183-page factory parts catalog fixes that. Published in 1982, it covers every replaceable component on these three models – the CC-50, CC-50A, and CC-50S. No aftermarket rewrites. No collapsed PDFs with missing pages. Original OEM print from Dynapac Mfg Inc., Stanhope, New Jersey.

The table of contents runs from Air Cleaner Assembly (page 68) straight through Water System Assembly (pages 86-97). Each model designation (CC-50, CC-50A, CC-50S) has its own column in the page number references, so you know exactly where to look. For example, Brake Assembly sits on pages 62-65 for all three models. Need the engine serial number to match a pump drive? Page 7 has the Pedestal Assembly and Pump Drive Assembly breakdown. The introduction on page 2 explains the indented parts list format – parts indented under an assembly are subcomponents of that assembly, and the quantity listed is per assembly, not per machine. Clear as a torque wrench click.

Engine & Pump Assembly – Page 9

This section covers the engine and pump assembly for all three models. The exploded view shows the mounting brackets, coupling, and pump drive. If you’re swapping a hydraulic pump on a CC-50A, you need the part number for the coupling – it’s index number 31 on the Main Assembly table (page 1 index). The catalog lists part numbers like 233088 and 850207. Don’t trust a generic seal kit when the original part number is in your hand.

Electrical Wiring Diagrams – Pages 29-32

Wiring on these compactors can get messy, especially after years of field repairs. Pages 29-32 contain the **Electrical Wiring Diagrams** for the CC-50, CC-50A, and CC-50S. These are factory schematics showing the starter circuit, alternator, gauges, and headlights (pages 112-113). I’ve used these to trace a no-start condition that turned out to be a bad ground at the battery bracket (part number 815290). When you’re dealing with safety lock assemblies (page 67) or horn circuits (page 114), having the factory wire colors and connector pinouts saves you from chasing ghosts.

Brake Assembly – Pages 62-65

Brake components are safety-critical. The Brake Assembly section spans pages 62-65 and covers the drum brakes on all three models. The exploded diagram includes the brake shoes, springs, adjusters, and the torque hub assembly (page 61). One thing I’ve learned: never reuse the retaining ring (part number 911082) on the brake valve – it’s a single-use item. The catalog identifies it clearly in the example on page 2. Torque specs for the brake mounting bolts? Those are listed in the Hydraulic Steering Traction section, pages 81-81A. Cross-reference those values with the torque hub specs on page 61. Factory numbers only.

7 Systems – From Fuel to Hydraulics

The catalog breaks down seven major systems: Fuel System (pages 15-16A), Hydraulic Assembly (71-80A), Hydraulic Steering Filter Assembly (page 75), Hydraulic Steering Traction (81-81A), Water System Assembly (86-97), Vibration Control Valve (144-149), and Cooling System (Radiator & Cooler Assembly page 7A-7B). Each section includes a parts list with index numbers linked to the exploded view. For the CC-50S, the Hydraulic Steering Traction section ends on page 81 (the manual shows page 81 for CC-50S, not 81A). Pay attention to those model-specific columns. The **Dynapac CC-50A CC-50 CC-50S 1982 Parts Catalog** is the only source that shows those differences.

Source Authenticity: OEM vs. Aftermarket

I’ve had techs bring me aftermarket parts catalogs that claim “interchange” for Dynapac rollers. Then they wonder why the staffa traction motor seal doesn’t fit. This catalog is the real deal – original factory PDF from Dynapac Mfg Inc. The front page states “Revised Feb. 1982, PA-50-PL.” That revision date matters because Dynapac updated the torque hub assembly (page 61) and the vibrometer components (pages 128-129A) during that production run. Aftermarket reprints often skip those updates. If you’re ordering parts for a CC-50A serial number after 1981, you need this edition. Check the DYNAPAC CC-50A CC-50 CC-50S 1982 Parts Catalog for guaranteed OEM accuracy. For other Dynapac models, see the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec or the Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer.

Does this parts catalog include torque specifications?

Yes. While the catalog is primarily for part numbers, torque values appear in the hydraulic and brake sections. For example, the Hydraulic Steering Traction pages (81-81A) list bolt torques for the traction motor mounting. The torque hub assembly on page 61 also contains nut torque values. You’ll need to cross-reference the part numbers with the torque chart embedded in the exploded view callouts. If you need a dedicated service manual with step-by-step rebuild procedures, pair this parts catalog with the factory service manual.

What is NSS mean in the parts list?

NSS stands for “Not Sold Separately.” It appears next to items that are only available as part of a larger assembly. For instance, the seal inside the steering valve (index number 1, part 814146) might be NSS – you’d have to order the entire valve assembly. Always check before you try to source just the seal.

Before you tear down that brake assembly or order a new hydraulic manifold valve (page 84), get the factory exploded view in front of you. This catalog gives you the part numbers, quantities, and model-specific callouts that aftermarket sources miss. Access the Factory Manual and keep it on your tablet or print the pages you need. Your Dynapac will run longer, and your parts counter won’t hate you.
