Dynapac CA-15A 1987 Parts Catalog – OEM Exploded Views & Part Numbers

If you’re trying to track down a part number for a Dynapac CA-15A vibratory compactor from 1987, you’ve probably already found out that aftermarket catalogs are useless. The wrong seal, the wrong bearing – that’s time and money gone. I’ve been turning wrenches since before most of you were born, and I learned one thing early: only the factory manual gives you the exact exploded view and part number. This Dynapac CA-15A 1987 Parts Catalog is the real deal – 170 pages of OEM data, not some photocopy of a photocopy.

Any shop that works on compaction equipment needs this on the bench. The manual covers serial numbers from 1651 and up, and splits everything by engine type – Detroit or John Deere. You get the part number, the quantity, and a clear exploded drawing. No guessing, no cross-referencing off blurry scans.

Dynapac CA-15A 1987 Parts Catalog: What’s Inside

The table of contents alone tells you this is a full machine breakdown. General assembly starts on page 2. From there you can jump to any system – power train, hydraulics, electrical, cab, water spray, you name it. The manual is organized the way a mechanic thinks: by functional group, not by some random index. For example, the entire hydraulic system is split into steering, traction, and vibration circuits, each with its own parts list.

One manual. One source of truth.

Electrical Assembly: Detroit vs John Deere

The electrical section is split between the Detroit and John Deere variants. Page 61 starts the Detroit electrical assembly, covering the alternator, starter, and all related wiring. The John Deere version begins on page 63. Both include part numbers for the harnesses, relays, and switches. If you’ve ever tried to order a voltage regulator for one of these machines without the factory diagram, you know the pain. This manual puts the right number in front of you.

What Valve Assemblies Does This Manual Cover?

Valve assemblies are critical on a vibratory compactor. The manual covers the vibration control valve (page 59), the manifold valve assembly (page 76), the steering valve assembly (page 107), and the Quikstop valve (page 57). Each assembly page has an exploded view with index numbers matching the parts list. For the hydraulic brake system on serial numbers 2080 and up, check pages 55A-55B. That’s not info you find in aftermarket catalogs.

Engine & Pump Assembly: Detroit and John Deere Coverage

Two separate engine sections: Detroit on page 15, John Deere on page 17. Each includes the pump assembly mounted to the engine. The traction pump, charge pump, and vibration/steering pump all have their own exploded views. If you’re rebuilding a traction motor, the assembly is on page 75. The charge pump assembly, valid for both pumps, is on pages 73E-73F. This is the level of detail that keeps a job from turning into a scavenger hunt.

170 Pages of OEM Part Numbers – Not Aftermarket Guesses

This catalog runs 170 pages total, with a numerical index from page 108 to page 113. That index lists every part number in numerical order and tells you which page to find it on. You don’t need to flip through the whole book. The exploded views are line drawings, clear enough to read on a greasy workbench. The part numbers are original Dynapac numbers, not some re-labeled cross-reference that may or may not fit.

Use the Exploded Views to Avoid Ordering the Wrong Part

Every major assembly – from the drum assembly (pages 34-35) to the water spray system (pages 41-44) – comes with an illustration that shows how parts fit together. The parts list indents subassemblies, so you know which washers belong to which bolt. For example, under the steering valve assembly, the index number points to a seal and a retaining ring, both indented to show they’re part of that valve. Ordering parts from this manual means you get the right o-ring the first time.

Does this manual include torque specs?

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

How do I use the numerical index to find a part?

The numerical index at the back (pages 108 to 113) lists every part number in numerical order. Find the part number, then cross-reference to the page number given. Then flip to that page, find the index number on the exploded view, and match it to the parts list for the description and quantity. This saves you from flipping through the entire book. I’ve used this method countless times for hard-to-find seals and bearings. It works every time.
