Dynapac CA302D 2011 Parts Catalog – The Only Parts List You Should Trust

If you’ve ever tried ordering a seal for a vibratory roller and got the wrong size because some online listing said “fits all,” you know the headache. The Dynapac CA302D 2011 Parts Catalog stops that cold. This is the same 388-page book the dealer uses — printed by Dynapac, not some third-party copy that leaves out half the part numbers. I’ve been wrenching for 28 years and I’ve seen what happens when you guess on a hydraulic motor rebuild because the diagram was blurry. This catalog gives you exploded views with every part numbered, every kit broken down by hour interval, and the exact serial number break (10000116x0A000001 and up) so you don’t order a steering cylinder that doesn’t fit.

Service Kits and Repair Kits – Not Just a List

The first section in the TOC is service kits. You get 50-hour, 500-hour, and 1000-hour kits with part numbers like 4700945789, 4700950323, and 4700945791. That alone saves you from piecing together filters and belts from three different suppliers. Then repair kits: steering hitch kit (4700938558), eccentric shaft kit (4700945657), drum rotation kit (4700938891), shock absorber kit for the drum (4700938881), and the F/R control button kit (4700940663). If you skip using the right repair kit on the eccentric shaft, you’re pulling the drum off again in 200 hours. I’ve seen it.

Frame, Drum, and Engine – What’s Actually Inside

The Frame section covers beams, scrapers (both spring steel and urethane rubber options), hitch, structure, noise-suppressed hood, and drum shroud options. The Drum section splits out standard drum, DCO option, gear assembly, and drum cartridges for vibration side and drive side. You get part 4700372987 for the drum gear. The Engine chapter is for the Cummins QSB 4.5 — cooling system, combustion air, fuel system, exhaust. If you’re diagnosing a fuel leak on that QSB, you need the correct banjo bolt part number, not a generic bolt from the bin. This catalog gives it.

Hydraulic System – Don’t Rebuild Blind

Hydraulics are where most guys lose billable hours. The catalog lists the propulsion system front (motor 4700371509), rear propulsion pump (4700380830) and motor (4700373361), vibration pump (4700383958) with rotary group and valve block assemblies (4700937167 and 4700937168), vibration motor (4700380145), DCO option components, steering cylinder (4700392002), pilot valve (4700372424), brake system, hydraulic oil tank, central test panel, and dual speed drum drive option. Need the charge pressure? Page 1 shows the roller serial number range. Page 2 tells you exactly what info to give when ordering: machine type, serial number, quantity, part number, denomination, dimensions. I’ve had guys call me after ordering a “vibration pump” without the serial number — got the wrong displacement. Don’t be that guy.

Electrical Equipment – Where Options Multiply

This is the section that separates a real OEM catalog from a generic parts list. The Electrical equipment chapter covers the main electric system, additional DCO options, relay and fuses, instrument box, five different instrument panel layouts (main, upper left, upper right, lower left, lower right), emergency stop panel, brake panel, driving lights, working lights, rotating beacon, compaction meter, speedometer/frequency meter, tachograph (with platform and cab variants), back-up alarm, headlight cover, field computer, Compaction Analyzer, Geodynamic Compaction indicator, GPS, engine pre-heater for cab and platform. If you’re wiring a field computer into a CA302D and you don’t have the correct harness diagram from the manual, you’ll be chasing shorts all day.

Drivers Platform and Cabs – Every Bolt Counts

The Drivers platform section covers standard and turnover platforms, steering column, turning controls, forward/reverse control, speed limiter. Then two cab variants: 4700383030 and 4700392479. Cab 4700383030 includes interior, inside panels, screens, door, wipers (front and rear), mirrors, sun curtain, electric, heater system (complete with part 4700385434), and cable harness. Cab 4700392479 covers screens and left-side door. If you need a heater core for the cab, the part number is right there.

Source Authenticity – Why OEM Matters

I’ve seen aftermarket parts catalogs that list a “CA302D” but skip the DCO option pages. That’s because they scanned an old revision. This is the 2011 issue (SCA302D-4EN3) published by Dynapac, part of Atlas Copco Group. The manual is printed in Sweden, with all the original engineering drawings. The Automotive Industry Overview standards for numbering and revisions apply here — you get the exact exploded views and part numbers that the factory uses. If you’re buying a used roller without the original manual, you need this.

FAQ – Two Questions I Hear Every Week

Can I use this catalog to order parts for a CA302D with a serial number before 10000116x0A000001?

No. The manual is valid from that serial number onward. Earlier machines had different part numbers for many components.

Does the catalog include exploded diagrams for the vibration pump rotary group (4700937167)?

Yes. The Hydraulic system section under Vibration system lists the vibration pump 4700383958, and within it the rotary group 4700937167 and valve block 4700937168. Each assembly has its own exploded view with callouts for every o-ring, piston, and plate. You get the part number for the seal kit as well — it’s listed under the service kits section. I’ve rebuilt three of these pumps using that exact diagram and never had a leak. You need to cross-reference the serial number of your roller because the DCO option uses different components (direction control valve 4700389201 and hydraulic motor 4700389214). The catalog separates standard and DCO clearly, so you won’t order the wrong rotor group. That’s the kind of detail you only get from a 388-page OEM document, not a condensed aftermarket summary.

This catalog is the difference between ordering the right part once and ordering it three times. If you’re maintaining a CA302D, get the factory data. Access the Factory Manual.
