Dynapac SD2550CS 2015 Parts Catalog

Ordering the wrong part for a Dynapac SD2550CS paver costs you money and downtime. I have watched guys order three different conveyor chains because they trusted a third-party list. The Dynapac SD2550CS 2015 Parts Catalog is the factory document that eliminates that problem. 893 pages of exploded diagrams and genuine part numbers, keyed to specific serial number breaks. This is what the assembly line uses.

A repair manual tells you how to take it apart. A parts catalog tells you what to put back in. This catalog lists every nut, seal, hose, and plate for the SD2550CS. Sections cover wear part kits for rubber plates, conveyor chain, auger wings, and service kits at 500 and 1000 hours. You get the exact part number, quantity, and the illustration that shows where it lives.

I have used this catalog on several paver rebuilds. When you need a conveyor motor gasket, you flip to page 45 and see the exploded view of the conveyor motor assembly. The part number 4812031231 is right there. That is the difference between getting the job done and ordering the wrong part twice.

Dynapac SD2550CS 2015 Parts Catalog: What’s Inside

Dynapac divides the manual into two main areas: Service, repair and wear part kits, and Mechanical. Under Mechanical you get Main frame, Conveyor, Push roller (hydraulic), Hopper, and Covering. Each section has sub-assemblies with part number callouts. The catalog also includes pre-packaged kits – like the Wear part kit auger wing Ø500mm – so you order a single kit instead of hunting for individual bearings and seals.

That is the kind of time-saver that pays for the manual on the first order. If you need the previous year’s data, check the Dynapac SD2550CS 2014 Parts Catalog.

893 Pages – Broken Down by Serial Number Range

Dynapac breaks the SD2550CS down by build date. You will see entries like ‘Push roller, hydraulic, cpl. (To 10002121K0C002520 / 10002119E0C001787)’ and then a separate listing for machines built after that serial. That level of granularity is missing from aftermarket copies. You must match your machine’s serial number before you order. Page 75 shows the push roller assembly for earlier machines – do not skip that step.

For machines with a later serial number, the catalog directs you to page 83. That is how Dynapac avoids mix-ups. The manufacturer, Dynapac, designs these machines to be repaired with factory-correct parts. Aftermarket catalogs often consolidate multiple variants into one, and that is where mistakes happen.

Service Kit Groupings and Wear Part Kits

This catalog includes pre-assembled service kits for maintenance intervals: Service kit 500 hrs TIER 3, Service kit 500 hrs Plus TIER 3, Service kit 1000 hrs TIER 3, and Service kit 1000 hrs TIER 3 stage 2. Each kit lists the individual components with part numbers. You can order the whole kit or source parts individually. Also included are Wear part kits for rubber plates, conveyor chain, conveyor drive, reversing roller, conveyor plates, conveyor guide plates, and auger wing.

If you are doing a conveyor overhaul, the Wear part kit conveyor chain is listed on page 7. That saves you from cross-referencing roller chains from generic tables. Do not waste time guessing – use the factory grouping.

Does This Catalog Cover the Conveyor and Auger Systems?

Yes. The conveyor section includes Gr.04 Conveyor, double no. of bars, the conveyor motor (4812031231), limit switches (PLC), potentiometers, and the chain guide and tensioner. The auger system appears under the wear part kits and also in the mechanical sections. Every bolt, bearing, and hydraulic line is called out. The catalog even differentiates between left-hand and right-hand conveyor limit switches – part numbers 4812044937 and 4812044936. That level of specificity is why OEM documentation beats aftermarket lists.

For the operator’s perspective, consider the Dynapac SD2550CS, SD2550C Operators Manual – OEM 568-Page Factory Specs. That manual covers operation and safety, while this parts catalog handles ordering.

Get the Right Part Number on the First Order

Here is the bottom line: aftermarket parts catalogs on websites usually copy the diagrams but leave out serial number breaks, supersession notes, and sometimes the correct quantities. This Dynapac document is the original 2015 publication. It shows you the exact part number you need. You still need to verify current availability with a dealer, but you start with the right number.

I have worked on enough pavers to know that ordering a ‘close enough’ part leads to fitment issues. For example, the Steering guide (4812036083) is unique to this paver. A third-party list might give you a generic guide that does not line up with the bolt holes. Not worth the call-back. Get the factory part number from this catalog.

FAQ

Can I use this parts catalog to rebuild the engine?

No. This catalog lists parts for ordering, not overhaul procedures. You need the service manual for that.

How do I know if a part number is still current?

Dynapac part numbers can supersede over time. The catalog reflects the numbers as of the 2015 publication date. If your machine has been updated under a service bulletin, the original number may have changed. You should always verify with the manufacturer’s current system before ordering. However, this catalog gives you the correct starting point. It shows the exact component in the exploded diagram, so you can describe it to the parts desk. I have had situations where aftermarket lists gave me the wrong number for an auger gear, but the factory catalog diagram showed the correct one. Use it as the foundation, then confirm current availability. That approach keeps your machine running instead of waiting on a return.

If you are tired of ordering the wrong parts and waiting on re-ships, get the factory document. Access the Factory Manual from AutoRepairManuals and keep it in your shop iPad. That will save you the headache. Pair it with the Dynapac SD2550CS SD2550C Operators Manual – Factory Specs & Safety for a complete shop reference.
