Dynapac CA402D Parts Catalog – 354 Pages of Factory Specs

I’ve been wrenching on heavy equipment for 28 years. You call me when a part number doesn’t match and the job’s on hold. That’s why Dynapac CA402D Parts Catalog sits on my bench – not some generic aftermarket PDF that swaps illustrations and hopes you don’t notice. This is the original OEM document from Dynapac, part number SCA402D-4EN2, covering rollers from serial number 10000118x0A000001 onward.

If you’ve ever ordered a steering cylinder seal kit for a CA402D and got the wrong one, you know the pain. This catalogue eliminates that guesswork. It’s 354 pages of exploded diagrams, part numbers, and quantities – the same data Dynapac dealers use. Ordering protocol is spelled out on page 2: machine type, serial number, quantity, part number, denomination, dimensions. Follow it, and the right parts show up.

Engine, Hydraulics, Drum, and Beyond: What’s Covered

Open this catalogue and you’ll find sections for every major assembly. The table of contents lists Service kits (50h, 500h, 1000h), Repair kits (steering hitch, eccentric shaft, drum rotation, shock absorber, F/R control button), Frame (scrapers, hitch, noise-suppressed hood options), Drum (cartridge vibration side and drive side, drum gear 4700372987), Engine (Cummins QSB 4.5, cooling, combustion air, fuel, exhaust), Transmission (rear axle limited slip and No-Spin options with differential and planet gear breakdowns), Hydraulic system (propulsion front and rear, vibration pump 4700383958 with rotary group and valve block, steering cylinder 4700392002, pilot valve 4700372424, brake system, oil tank, dual speed drum drive), Electrical equipment (relay and fuses, instrument panels, emergency stop, lights, compaction meter options, GPS), and Drivers platform (cabs 4700383030 and 4700392479 with interior, door, heater, wipers, mirrors). Decals and standard equipment round it out.

354 Pages of Exploded Views and Part Numbers

Every page is a working document. The exploded views are drawn to Dynapac’s original engineering specs – not redrawn by a third party who missed a bushing. Each part number is listed with quantity required and notes like “included when buying the assembled unit above” (page 3 explains that dot-and-indent system). This is the same document that parts countermen use. When you need 4700945789 Service kit 50 h, you see exactly what’s in it. No guessing.

Why OEM Documentation Beats Aftermarket Copies

I’ve seen aftermarket parts catalogs that swap a bolt grade or omit a seal because they “looked the same.” That costs you downtime. This is a direct factory scan – no OCR errors, no re-labeled illustrations. Dynapac CA402D Spare Parts Catalogue is the genuine article. Compare it to Dynapac CA402D 2011 Parts Catalog from the same source – consistency across revisions. The earlier DYNAPAC CA402D Spare Parts Catalogue SCA402D-3EN3 was superseded by this 4EN2 edition. That’s how OEMs handle changes. Aftermarket reprints don’t.

Use the Ordering Protocol on Page 2

Flip to page 2. It tells you exactly what information to provide when ordering spare parts: 1. Type of machine, 2. Roller serial number, 3. Quantity required, 4. Part number, 5. Parts denomination, 6. Dimensions when ordering per length. It’s printed in English, Swedish, German, Italian, Spanish, and French – so you can hand it to any supplier. Follow that, and you avoid the headache of wrong parts. This is the same protocol Dynapac recommends in their Automotive Industry Overview – precision in identification.

Audience Fit: Who Needs This Catalogue?

If you maintain a fleet of CA402D rollers, you need this. If you’re a shop that subcontracts compaction work, you need this. Even a home mechanic who bought a used CA402D at auction – without this catalogue, you’ll waste hours cross-referencing parts on forums. It’s a parts catalog, not a service manual, so you won’t find torque specs or step-by-step rebuilds. But it gives you the exact part numbers and exploded views you need to order the correct components. Pair it with a service manual for complete coverage.

Dynapac CA402D Parts Catalog: What the TOC Reveals

The table of contents is organized by assembly groups. Each group has multiple subgroups with part number references. For example, under Hydraulic system > Vibration system > 4700383958 Vibration pump, you get two subassemblies: 4700937167 Rotary group, cpl and 4700937168 Valve block, cpl. That level of detail lets you rebuild instead of replacing entire pumps – saving money and downtime. The Electrical section even covers option packages like Compaction Analyzer, GPS, and tachographs.

Does this catalogue include torque specifications or repair procedures?

No. This is a parts catalog. It provides exploded views and part numbers only. You need the service manual for torque specs and disassembly steps.

Can I use this to rebuild the hydraulic pump for my CA402D?

Yes, with the right companion documents. The exploded view of the vibration pump (4700383958) shows the rotary group and valve block as separate assemblies with their own part numbers. You can order the individual components – bearings, seals, valve spools – without buying a complete pump. However, disassembly and reassembly procedures, including torque values and clearances, require the factory service manual. This catalogue gives you the parts identification; the service manual gives you the how-to. Together they cover every aspect of a hydraulic pump rebuild.
