Dynapac CA300D Parts Catalog – OEM Factory Spare Parts Guide

If you’ve ever ordered a replacement part for a Dynapac CA300D vibratory roller and got the wrong bearing or a hose that’s two inches short, you already know the pain. A tenth of an inch off on a hydraulic fitting can sideline a machine for a whole shift. That’s why this Parts Catalog exists – it’s the exact same document the Dynapac dealer uses when you call in a part number. 316 pages of exploded diagrams, factory part numbers, and ordering instructions. No reprints. No aftermarket nonsense.

I’ve spent enough years wrenching on heavy equipment to tell you: the difference between an OEM catalog and a third-party parts list is the difference between a 100% correct part and a “close enough” gamble. Close enough costs you overtime. The CA300D uses a CUMMINS 4BTA 3.9C diesel engine – that engine has specific fuel injectors, gaskets, and filters that don’t interchange with any other model. This catalog shows every one of those components with the original Dynapac part numbers.

Spare Parts Ordering Instructions – What You Need to Give the Dealer

Page 4 of this catalog spells out exactly what information to provide when ordering: machine type, roller serial number, quantity, part number, denomination, and dimensions for meter goods. Miss one of those six items and you’ll get a “we need more info” email. The manual also includes a notes section on page 5 for your own markings. I’ve seen guys skip the serial number and end up with a part that fits a CA300 but not the D variant.

Engine Group Parts – CUMMINS 4BTA 3.9C Coverage

The CA300D Parts Catalog dedicates multiple sections to the engine. You get exploded views of the cylinder head, fuel system, cooling, and lubrication circuits. Each component is labeled with its part number and the quantity per machine. If you need a thermostat housing gasket, you’ll see it listed with the correct height and material spec. This isn’t a generic engine manual – it’s specific to the Dynapac installation.

Vibratory System Components – Drums, Bearings, and Mounts

Vibratory rollers live and die by their bearings. This catalog shows the eccentric weight assembly, the drive motor, and the isolation mounts. Part numbers for the seals and bearings are right there – no cross-referencing from a generic bearing catalog. The Vibratory Roller CA300D section (starting after the engine group) lists every wearable item you’ll need for a drum rebuild.

Hydraulic and Electrical Schematics – Pictorial Only

Because this is a parts catalog and not a service manual, you won’t find torque specs or wiring diagrams. What you do get is a set of assembly drawings that show how every hose, fitting, wire harness, and connector goes together. The part callouts identify each hose length and fitting thread. If you’ve ever chased a hydraulic leak and couldn’t find the right O-ring, these illustrations save you from pulling three hoses to get one number.

Is This Manual for DIY Mechanics or Professional Shops?

Both. A home-garage owner who maintains his own CA300D will use this catalog to order exact parts from the local Dynapac dealer. A fleet shop will use it to stock common consumables and avoid last-minute part number calls. The 316 pages cover the entire machine: frame, cab, steering, brakes, and options. There’s even a section for “parts service info” (page 5) where you can record dealer contact and price updates.

Why OEM Documentation Beats Aftermarket – Every Time

Third-party parts catalogs often copy drawings from earlier revisions or skip components. This one is the genuine Dynapac publication SCA300D-1EN7, valid for serial numbers starting with 74220300. The Dynapac engineering group updates these catalogs when component suppliers change. Using an old copy means you might order a part that’s been superseded. This PDF is the current release from 2009-04, still in use today. I’ve seen aftermarket catalogs list a gasket that doesn’t exist for the 4BTA – that costs you a week of downtime.

FAQ

Does the catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. You’ll get part numbers and assembly drawings, but no bolt torque values.

Can I use this to order parts for a CA300 (non-D) model?

Likely not. The CA300D has a different drum assembly and engine mounting. Always check your serial number against the valid range printed on page 3.

What format is the manual delivered in?

PDF. 316 pages, indexed by bookmarks. You can search by part number or component name across the entire document.

How do I know if my serial number falls within the covered range?

The catalog covers rollers with serial numbers from 74220300 and up. If yours is earlier, you’ll need the previous issue (SCA300D-1EN6). The page 3 table lists all past issues.

This is the manual that should be sitting on your workbench next to the laptop. Access the Factory Manual and stop wasting time calling dealers just to get a part number.
