Dynapac CA 30, CA 30D Parts Catalog – Factory OEM Spare Parts Manual

If you are wrenching on a Dynapac CA 30 or CA 30D vibratory roller and you do not have this Parts Catalog open on your bench, you are guessing. Guessing means ordering the wrong hydraulic pump, returning it, losing a day. I have seen it too many times. This is the same 148-page document that Dynapac shipped with the machine—factory exploded views, genuine part numbers, and a numerical register that lets you cross-reference anything. That is what you get when you access the factory manual from AutoRepairManuals.

148 Pages of OEM Spare Parts Data

Page counts do not lie. The manual splits into 11 groups, starting with General View (page 1) and running through a full Numerical Register at the end. Group 1 covers the Frame—tractor upper section, radiator stand, steering link. Group 2 gets into the Drum assembly, including the torque hub and drive unit. If you need to replace a shock absorber on the drum or order a new planet gear, the diagram on page 6 of the group tells you exactly which part number to call your dealer with.

Engine and Fuel System: What Group 3 Covers

Engine parts for the Deutz diesel F6L 912 are shown with the air cleaner, fuel system, and hydraulic pump gearing all broken out in separate sections. The fuel system page lists injectors, lines, and the lift pump as individual line items. No generic “fuel pump assembly” label—you get the exact OEM number. That matters when you are ordering from a parts counter and they ask for the suffix.

Transmission and Brake Components – Group 4

Three-speed gear box, wheel axle, planetary gearing, differential carrier, and brake assemblies. The disc brake section inside the gear box group is separated from the service brake on the wheel axle. You can find the brake disc part number without pulling the whole axle. The transmission group also includes the wheel and tire assemblies with rim sizes and bearing numbers.

Does This Manual Include Torque Specs?

This is a parts catalog, not a service manual. You will not find torque values for head bolts or transmission fasteners here. What you will find is the torque hub assembly in Group 2 (Drive Unit) with an exploded view of every bearing, seal, and gear inside that hub. If you are rebuilding a torque hub, you need the parts breakdown to order the correct seal kit. Pair this catalog with the factory service manual for torque specs. That combination covers any rebuild.

Why Factory OEM Documentation Beats Aftermarket

I have seen third-party catalogs that combine multiple model years into one drawing—then you order a part that does not fit. This manual is specific to the CA 30 and CA 30D. The diagrams are drawn from the original Dynapac prints. The numerical register at the back lists every part number from all groups so you can start with a worn bearing number and find its exact location on the explosion. Dynapac themselves published this in Sweden. If you want to understand how the compaction industry standardizes documentation, the Automotive Industry Overview gives context on why OEM sourcing matters.

What the Hydraulic System Group Covers

Group 5 is the thickest section. It splits into propulsion, drum drive (CA 30D only), vibration, and steering. You get separate diagrams for the variable displacement pump, charge pump, control valves, hydraulic motors for wheel and drum drive, and the manifold valve. The steering section covers the wheel tube, steering unit, and steering cylinder. If you are troubleshooting a drift issue, the diagram for the steering control valve shows each spool and seal individually. No assembly-level drawing that hides internal parts.

Can I use this parts catalog to identify parts for the CA 30D drum drive?

Yes. Group 2 and Group 5 both separate CA 30 from CA 30D components. The drum drive hydraulic system is explicitly labeled for the CA 30D on pages 6-24 of Group 5. Each motor and valve has its own diagram with callouts.

How do I find a part number if I only have the old part in hand?

Look up the number in the Numerical Register at the end of the 148-page catalog. That register lists every part number from all groups and tells you the exact page and position number where that part appears on the exploded diagram. For example, if you have a seal from the hydraulic motor, you can find its group and order the correct replacement without disassembling the whole motor again. This saves you from ordering a seal that looks the same but has a different inner diameter – a mistake I have seen cost a shop two days of downtime.

If you work on heavy compaction equipment, you know that one wrong part number can stall a job. This catalog puts the factory identification data in your hands. Stop ordering parts by guess and cross-reference. Access the Factory Manual now.
