Dynapac SD2550CS 2014 Parts Catalog – If You’re Ordering Parts Without This, You’re Wasting Money

I’ve been turning wrenches for 28 years. You know what burns my time? Watching a guy order the wrong drive gear box because he guessed the serial number range. This Dynapac SD2550CS 2014 Parts Catalog is 949 pages of factory-correct part numbers, exploded diagrams, and cross-references that go down to the nut and bolt. If you maintain one of these pavers, you need this on your tablet, not a PDF from some forum.

Gr.02 Track Group: Left and Right Assemblies with Drive Gear Box Numbers

The track group section covers both long right-hand (4812043024) and left-hand (4812043025) assemblies. Each includes the track drive (4812043886), drive gear box (4812035017), and track chain (4812043901) with the wear part kit for rubber plates (4812035551). The manual also lists the track cleaner assembly (4812043329) and the locking lever (4812043349). If you need to rebuild one side, the part numbers are identical except for orientation – double-check the serial number prefix. This catalog is valid for SD2550CS machines with serial number 0G001000 and up. I’ve seen shops order the wrong track roller (4812043052 vs 4812043053) because they skimmed the drawing. Don’t be that guy.

What Systems Are Covered in This Parts Catalog?

Seven main groups: Gr.01 Main frame (including side arm guiding and splash guard), Gr.02 Track group (two variants, one for later serial ranges), Gr.03 Push roller hydraulic system, Gr.04 Conveyor (single and double bar versions), Gr.05 Thermo hopper and front hopper flap assemblies, Gr.06 Side screed arms with hydraulic locking, and Gr.07 Drive for Tier 3 engine. Each group breaks down into subassemblies with individual part numbers, quantities, and exploded-view drawings. The conveyor section alone has 30+ part numbers for wear parts, chain guides, and tensioners. You want to know what conveyor motor fits? It’s 4812031231, and the hydraulic conveyor block is 4812029121.

949 Pages – But You Need to Read the First Two Pages

The opening pages (page 1-3) contain the legal warnings and the statement that this catalog contains no safety regulations – it’s strictly for parts ordering. Any damage from using unauthorized parts voids the warranty. The table of contents starts on page 4 and runs through all 949 pages. Every assembly has a page reference. For example, the main frame (Gr.01) starts on page 7, the track group on page 11. But here’s the kicker: the manual lists which assemblies apply to your specific serial number range. If you have an older machine, you may need the alternate track group (Gr.02, part number 4812027763). Ignoring that will cost you shipping fees and downtime.

Verify Your Serial Number Before You Order a Single Part

The catalog is keyed to serial number 0G001000. Some sections list additional valid serial numbers like 0G000988, 998, 1001, 1016, and beyond. The hopper groups have five different part numbers depending on the build date. If you order a front hopper middle long (4812028712) without checking your serial against the note “Valid for s/n: 0G000988, 998, 1001, 1016, ff,” you could end up with a piece that doesn’t bolt up. I don’t care if the parts guy says it “looks close” – use the factory documentation.

Conveyor and Hopper Assemblies: Exploded Views and Wear Kit Numbers

Two conveyor variants exist: the standard (Gr.04, 4812027438) and the double-bar version (4812028401A). Each has its own wear part kit for conveyor plates (4812028402) and guide plates (4812028403). The hopper section covers thermo hopper (Gr.05, 4812044750) with bulk material flap (4812028563), and the front hopper flap version (4812044751). Part numbers like 4812029458 for the hopper lock appear across multiple hopper variants – that’s the factory doing you a favor by keeping common parts common. Still, the manual shows exactly which lock goes to which assembly.

Source Authenticity: OEM Dynapac Printing, Not Aftermarket Rework

This is an original Dynapac parts catalog published in 2014 by Dynapac GmbH, Wardenburg, Germany – a subsidiary of Atlas Copco. The cover says “ORIGINAL DYNAPAC” and page 1 carries the copyright. Any unauthorized use or copying is prohibited. That tells me it’s the real deal. Aftermarket parts catalogs often use generic illustrations or miss supercessions. This one lists every part number, every revision note, and the serial number ranges. Dynapac engineering put this together for their dealers. If you’re working on a paver, you want dealer-level accuracy. For context on why OEM documentation matters in heavy equipment, check the Automotive Industry Overview on Wikipedia.
