Dynapac CC 20 Parts Catalog – Factory OEM Parts Diagrams for Vibrating Roller
Ordering the wrong part for a Dynapac CC 20 vibrating roller costs you time and money. I have seen guys pull a pump based on a worn label, only to find the replacement doesn’t fit because they went off an aftermarket list. This 66-page Dynapac CC 20 Parts Catalog is the factory-issued spare parts list – Swedish, English, German. Every exploded diagram and part number comes straight from Dynapac, valid from roller serial 489513 with the Deutz F4L912 engine. If you need to find a seal, a motor, or a steering cylinder without guesswork, this is the document you keep on the bench.
Engine F4L 912 Deutz – Parts Breakdown (Page 12)
Page 12 gives you the full engine assembly with every component listed. Pistons, rings, gaskets, injection pump parts – all called out with original part numbers. No aftermarket interpretation; you see exactly what Dynapac installed. When you need to order a head gasket or a fuel line, you pull the number from this page and hand it to the supplier. Saves a return trip.
Hydraulic Diagram and Pump Systems (Pages 16-20)
This manual groups the hydraulic sections together. Page 16 is the overall hydraulic diagram. Then page 17 covers the power train pump, page 18 the power train system, page 19 the vibration and steering pump, and page 20 splits into propelling and vibration systems. Each page has an exploded view with callouts for O-rings, fittings, and pump housings. If you are rebuilding a drive motor, you can see exactly which seal kit number fits the front drum or rear drum (page 8 covers those drums).
3 Wiring Sections Covering Electrical and Battery
Electrical problems on a roller can be a headache. This catalog includes a wiring diagram on page 32 and the battery group on page 36. The electrical equipment section on page 34 lists switches, relays, and connectors. With these pages you can trace a harness and order the correct pigtail or relay. I have seen DIY guys burn an hour guessing at fuse ratings – this catalog gives the factory part, so you know the amp rating is correct.
Cab ROPS and Mounting – What the Manual Shows
Pages 39 through 45 cover the cab: the ROPS structure, cab mounting hardware, and the complete cab assembly. If you need a new windshield, wiper, or defroster duct, the exploded views on page 7 (cab heater and defroster) and page 45 (cab) show each piece. The cab mounting page (41) lists all bolts, isolators, and brackets. Safety note: never mix ROPS bolts with generic hardware – the catalog gives the exact grade and length.
Control Systems: Brakes, Vibration, Forward/Reverse (Pages 27-30)
Four pages dedicated to operator controls. Page 27 covers tachometer, governor, and stop control. Page 28 is forward/reverse. Page 29 covers vibration controls. Page 30 covers brake controls. Each shows the lever assembly, cables, and linkages. Ordering a broken parking brake lever? Page 30 identifies every spring and pin. This is the kind of detail that keeps a roller on the job instead of waiting for a mis-shipped part.
Dynapac CC 20 Parts Catalog – Why OEM Documentation Matters
Aftermarket parts catalogs often renumber parts or skip sub-assemblies. This factory document uses Dynapac’s own numbering system – what you see is what the dealer stocks. The manual also includes plates and decals (page 37) and tools and equipment (page 38). For the full industrial context on why OEM documents reduce errors, check the Automotive Industry Overview. Likewise, the Automotive Industry Overview confirms that factory manuals cut down misorders.
- Does this catalog include torque specs?
- No. It lists part numbers, not torque values.
- How do I know which part number is correct for my roller?
- The catalog is organized by system and includes exploded diagrams with callouts. Each part has a unique number and reference to the assembly. For example, the hydraulic pump on page 17 shows every seal, O-ring, and fitting. You cross-reference the part numbers with the roller serial number range given on the cover. If your serial is above 489513, this catalog applies. Always check the “Valid from roller no.” on the front page. This avoids ordering the wrong pump or motor for your specific build.
If you are tired of chasing wrong parts from generic suppliers, get the real thing. Download the Factory Manual from AutoRepairManuals and have the right part number in your hand before you call the supplier.
