Dynapac CA300D Parts Catalog – 246 Pages of OEM Spare Parts

I’ve been wrenching on heavy equipment for 28 years, and the single biggest time-waster in this trade is ordering the wrong part. You pull a pump, find the number is worn off, guess at a replacement, and three days later the machine is still sitting. The Dynapac CA300D Parts Catalog kills that guesswork. This is the same 246-page bound book that Dynapac dealers use. It’s not a reprint or a scan of a scan – it’s the original factory PDF from the Atlas Copco group, valid for rollers starting at serial number 10000115x0A000001. Every part number, every exploded view, every service interval kit is laid out so you can order with your eyes closed.

Wasted a morning on a phone call trying to cross-reference a piston seal? I’ve done it. That stops here. This catalog gives you the exact Dynapac part numbers for service kits at 50, 250/750, 500, and 1000 hours. It also lists repair kits for the steering hitch, eccentric shaft, drum rotation, and shock absorbers. You get the frame sections, drum cartridge details, engine components for the Cummins 4BTA 3.9C, transmission options, and the full hydraulic system breakdown. No more calling the dealer and hoping the kid at the counter knows what a “vibration pump” means. You’ve got the number right in front of you.

Service Kits and Repair Kits

The first section in the Dynapac CA300D catalog covers scheduled maintenance. Service kit 4812156751 for 50 hours, 4700938527 for 250/750 hours, 4700950196 for 500 hours, and 4700950197 for 1000 hours. I’ve seen shops wire together a generic filter set and blow a seal two weeks later. Don’t. The O-ring compounds and filter micron ratings are specific to the CA300D. Repair kits follow: steering hitch (4700938558), eccentric shaft (4700945657), drum rotation (4700938891), and shock absorber kit for the drum (4700938881). Each kit includes every gasket, seal, and fastener you need – not a “might fit” assortment. When I rebuilt a drum cartridge on one of these, having the right eccentric shaft kit saved me a trip to the parts store.

Frame, Drum, and Engine Sections

Under the Frame heading you get the main structure, scraper beams, hitch, side covers, and options for urethane rubber or spring steel scrapers. The Drum section breaks down the drum itself, the vibration-side cartridge, drive-side cartridge, and the drum gear (4700380462). I’ve seen guys try to order a drum motor by measuring bolt patterns – that’s how you end up with a $2,000 paperweight. The catalog gives you the exact assembly drawing and part numbers. The Engine section covers the Cummins 4BTA 3.9C, fan and fan clutch, cooling system, combustion air, fuel system, exhaust, and the pre‑air cleaner option. If you need a fan belt or a fuel injector, you’ll find it here.

Hydraulic System: Factory-Coded Components

This is where the Dynapac CA300D Parts Catalog really pays for itself. The hydraulic system is split into propulsion (front and rear), vibration, steering, and brake systems. Each component has a unique seven-digit part number. Front propulsion motor 4700371509, rear hydraulic pump 4700395385, vibration pump 4700395384, vibration motor 4700395386. Steering valve 4700376000 and steering cylinder 4700392002. There are also central test panel options from Sauer Danfoss and Rexroth. If you’re rebuilding the hydraulic oil tank or replacing a seal in the brake system, the exploded view tells you the stack order and the correct hardware. No more “that looks like it fits.”

Transmission and Rear Axle Options

The CA300D came with multiple rear axle configurations: a limited-slip axle (4700383857), a standard axle (4700393002), and a No-Spin option (4700383856). Each axle group includes differential housing, brakes, and planet gear assemblies. The Parts Catalog lists every gear, shim, and bearing. I’ve seen a differential setup fail because someone swapped a planet gear from the wrong axle. The manual prevents that by giving separate part numbers for each variant. If you’re replacing a wheel motor or a brake disc, you need the correct axle code. Page 2 of the catalog reminds you to quote the roller serial number – that’s the only way to match the exact axle type.

Why Use OEM Parts Documentation?

I’ve got a stack of aftermarket parts catalogs in my office that are useless for a Dynapac machine. They take a generic drawing, slap a “similar to” label, and leave you guessing. This is the real deal – printed by Dynapac (now part of the Dynapac group) and delivered as a PDF with searchable bookmarks. The index includes numerical listings so you can cross-reference any number. If you’re working on a DYNAPAC CA300D Spare Parts Catalogue SCA300D-1EN7 or need parts for related models like the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec or the Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer, this is the only source I trust. For a broader perspective on why documentation matters in heavy equipment maintenance, see this Automotive Industry Overview.

Does this catalog include torque specifications for the CA300D?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views, not torque values or repair procedures. You need the separate service manual for assembly specs.

Can I use this PDF on a tablet in the shop?

Yes. The file is a standard PDF with bookmarks for every major section – service kits, frame, drum, engine, transmission, hydraulic system, electrical, driver’s platform, and decals. I load it on a cheap rugged tablet and zoom in on the exploded drawings. You can search by part number instantly. That beats flipping through a greasy paper catalog any day.

Look, I don’t sell fluff. I sell tools that keep your machine running. If you need to order parts for a Dynapac CA300D vibratory roller, this catalog is the difference between a five-minute parts lookup and a week of downtime. Access the Factory Manual now and get back to turning wrenches.
