Dynapac CA-30, CA-30A, CA-30D, CA-30PD 1984 Parts Catalog

You ever watch a journeyman mechanic burn three hours chasing a part number because somebody lost the original catalog? I have. That’s money down the drain on a job that should take twenty minutes. This 1984 Dynapac CA-30, CA-30A, CA-30D, CA-30PD parts catalog puts every OEM part number, exploded view, and ordering code right on your bench. No photocopies, no third-party reprints, no mislabeled drawings. You get the factory document that Dynapac MFG Inc. issued out of Stanhope, New Jersey, back when they still stamped serial numbers into the frame.

Page 2 of this manual tells you exactly how to read the index – major assemblies listed upfront, reference numbers keyed to exploded views, indented subassemblies with their own quantities. If you’ve ever ordered a steering valve seal and ended up with a retaining ring because the parts guy misread a line, you know why that matters. The entire layout matches the machine as it came off the line.

Engine & Pump Assembly – CAT and Detroit Options

Two engine families are covered in this Parts Catalog: CAT and Detroit Diesel. You’ll find the Engine & Pump Assembly section starting on page 9 for CAT, page 44 for Detroit. The Engine Emergency Shutdown components and Exhaust & Muffler Assembly are listed separately. If you’re pulling a pump drive or rebuilding the traction pump, the exploded views on pages 37 and 45 show every bolt, seal, and coupling.

Electrical Wiring Diagrams – Get the Layout Before You Cut

Electrical gremlins sink more field time than any other system. The E section of this catalog includes full Electrical Wiring Diagrams. Before you splice a single wire on a CA-30D, flip to the diagram pages. You’ll see exactly where the headlights, horn, and tachometer cabling route. No guessing which color wire feeds the vibration control valve – it’s right there in black and white (well, monochrome line art, but you get the idea).

Fuel System, Valve Components, and Hydraulic Schematics

The Fuel System section (pages 13-14 for CAT, 13-14A for Detroit) shows the tank, lines, and filter setup. The Control Valve, Vibration and Dual Amplitude Control Valve sections give you the full valve assemblies, including the steering valve on page 108. Hydraulic schematic pages trace the circuit from pump to motor. When you need a replacement hydraulic oil filter, the part number is in the Hydraulic Oil Filter listing – no cross-referencing required.

3 Model Variants, One Parts Catalog

This catalog covers the CA-30, CA-30A, CA-30D, and CA-30PD. Each model has its own page-number column in the index (right side of page 3). For example, the Drum Module Assembly shows different page numbers: CA-30 and CA-30D share page 85, but CA-30A uses page 83, and CA-30PD uses page 85 again. If you don’t check that column, you’ll order the wrong drum motor. The index also flags which models use a Cab Assembly (page 121 for CA-30, CA-30D, CA-30PD; page 121 for CA-30A as well – but check the footnotes on engine variants).

Source Validity – OEM Print, Not Aftermarket Copy

I’ve handled aftermarket parts catalogs that redraw the illustrations and drop half the callouts. This is the original factory print – Dynapac MFG Inc., revised January 1984. The hydraulic circuit diagrams, the torque specs for the drive hub, the part numbers for the Rollover Protection Structure (ROPS) – all come straight from the manufacturer. You can verify the part numbers against what’s actually stamped on your machine. That level of trust doesn’t exist with a scanned-and-OCR’d third-party version. Dynapac still supports some of these machines, but you need the correct base numbers to order anything.

If you’re working on a similar vibratory compactor from the same era, check out the Dynapac PL2000LS Parts Catalog (258 Pages) – OEM Factory Spec or the Dynapac PL2000LS Parts Catalog – Factory OEM Specs for Cold Planer.

The DYNAPAC CA-30/A/D/PD 1984 Parts Catalog you’re looking at is the exact same document that sat in dealer parts departments from 1984 onward. 168 pages, sectioned by system, keyed to exploded diagrams. Every major assembly from Air Cleaner (page 40) to Water System (page 70) is covered. No filler, no generic illustrations – just the factory data.

FAQ

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities only.

What is the difference between the CA-30 and CA-30A models in this catalog?

The index shows different page numbers for several assemblies between models. For instance, the Drum Module Assembly for CA-30 is on page 85, while for CA-30A it’s on page 83. The wiring diagrams also differ – CA-30 and CA-30D use a CAT engine on page 9, but CA-30A and CA-30PD use Detroit on page 44. The cab assembly and decal locations vary as well. If you have a CA-30A with a Detroit engine, make sure you follow the CA-30A column – ordering parts from the CA-30 column will give you CAT-specific components that won’t fit. The manual clearly separates these by model designation in the index, and each exploded view is labeled accordingly.
