Dynapac CA280STD 2011 Parts Catalog – OEM Factory Specs

If you are ordering parts for a Dynapac CA280STD 2011 Parts Catalog roller, you need the right numbers. I have seen too many guys guess at part numbers and end up with a box full of wrong seals or a steering cylinder that does not fit. This is a 220-page factory catalog straight from Dynapac, not some aftermarket reprint that swaps out figure numbers. It covers rollers with serial number 10000113x 0A000001 and up, which is the second edition (SCA280STD-4EN2) published in 2011. The engine is a Cummins 4BTA 3.9C diesel. If you work on these rollers, you need this on the bench next to the coffee cup.

Parts Catalog Structure for the CA280STD

The book is organized the way a mechanic thinks: by major assemblies. You get separate sections for Service kits, Repair kits, Frame, Drum, Engine (including fan clutch, cooling, combustion air, fuel, exhaust), Transmission (rear axle with limited slip or no-spin option), Hydraulic system (propulsion, vibration, steering, brake, tank, central test panels), Electrical equipment (system, control panel, optional beacon/back-up alarm/compaction meter), Drivers platform (canopy, ROPS, cab options, wipers, mirrors), Decals, Standard equipment, and Optional equipment (including air conditioner and heater). Each exploded view includes a parts list with class codes and notes. Parts indicated by a dot and moved right are included when buying the assembled unit above.

Why OEM Factory Specs Matter

Aftermarket catalogs often use generic drawings or mismatch part numbers. This Dynapac original uses factory part numbers like 4812156751 for the 50-hour service kit, 4700938527 for the 250/750-hour kit, and 4700950196 for the 500-hour kit. The serial number break is critical – page 1 tells you this catalog is valid from 10000113 x 0A000001. Order a part for the wrong series and you get a different bolt pattern. I have been there. Not doing it again.

Does This Manual Cover Your Serial Number?

Look at the serial number plate on your roller. If it starts with 10000113x 0A000001 or higher, this 2011 catalog (issue SCA280STD-4EN2) is correct. If your machine is older than that, you need the earlier issue SCA280STD-4EN1 from 2010. The catalog tells you that on page 1: it lists both issues. Never ignore that line – I have seen a shop order a steering valve for the wrong serial range and lose a whole day.

Ordering Parts: The Right Way

Page 2 of this catalog lays out exactly what you need to give the parts counter: machine type, roller serial number, quantity, part number, denomination, and dimensions if ordering by length. In six languages. I keep a copy of that page laminated near the phone. If you skip the serial number, expect delays. The catalog also includes a numerical index at the back so you can cross-reference a part number back to its assembly drawing.

Transmission and Drivetrain Breakdown

The Transmission section covers rear axle and wheels, with two differential options: limited slip (part 4700383857) and no-spin (part 4700383856). Each includes differential housing, brakes, and planet gear breakdowns. The hydraulic system is detailed with pump and motor numbers for propulsion, vibration, and steering. For example, the steering valve is 4700376000 and steering cylinder is 4700392002. If you need a vibration motor, it is 4700395386. All factory numbers – no guessing.

3 Major System Sections to Check First

Hydraulic system – propulsion pump 4700395385, motor 4700375999. Engine – cooling system, fuel system, exhaust. Drivers platform – cab options with wipers, mirrors, work lights. The optional equipment section covers air conditioner and heater units with their own part numbers like 4700383413 for the condensor assembly. If you have a machine with a heater, part 4700385222 is your heater unit.

Electrical Equipment and Options

The electrical section shows the entire wiring system, control panel, and optional rotating beacon, back-up alarm, and compaction meter. If your roller has a Sauer Danfoss or Rexroth central test panel, those are listed separately. The variable rear axle motor option (propulsion motor 4700373361 and pump 4700380830) is also covered. Never replace a sensor without checking the schematic against the actual machine – wire colors here are factory correct.

FAQ

Can I use this catalog to order parts for a CA280STD built in 2009?

Only if the serial number is 10000113x 0A000001 or higher. Earlier machines require the 2010 issue (SCA280STD-4EN1). Check your serial plate.

Does this catalog include torque specs for the drum bearings?

No. This is a parts catalog, not a service manual. It gives part numbers and exploded views. For service procedures, get the factory repair manual.

I have been turning wrenches for 28 years. When I need a part number for a Dynapac CA280STD, I reach for this catalog. It keeps the guesswork out and the billable hours in. Access the Factory Manual and keep it on the tablet next to your toolbox.
