Dynapac CA 252, CA 302, CA 262, CA 362, CA 402 User Manual – Factory Specs That Keep You Out of Trouble

If you’ve ever had a roller come in with a weird hydraulic leak and the aftermarket book told you the wrong filter size, you know the frustration. That’s why I only trust OEM manuals. This Dynapac CA 252, CA 302, CA 262, CA 362, CA 402 User Manual is the real deal – 340 pages of factory-published data from Sweden, not some third-party reprint. I’ve torqued more head bolts than most people have had hot meals, and I can tell you: skipped steps cost time and money. This book covers the whole range of single-drum compactors from the 252 up through the 402, plus the 512/602 variants. The engine section alone will save your back.

This manual is 340 pages. That’s a lot of paper.

Safety Manual: Why You Read It Before Turning a Key

The second section isn’t just boilerplate. Dynapac wrote a dedicated safety manual covering proper operation, lockout procedures, and what to do when you’re working around the roller in a trench. Page numbers are in the document, but I care about the content: it tells you which pins to engage before lifting the hood, and it lists the specific pressure relief valves for the vibration system. If you skip this, you’re asking for a hydraulic injection injury. The aftermarket stuff leaves this out. Not Dynapac.

Operation: Know Your Controls, Not Your Neighbor’s Guess

The Operation chapter lays out the instrument panel, direction control, and vibration settings for each model. The CA 252 and CA 302 share the same control layout, but the CA 402 has a different engine throttle linkage. The manual calls out the difference in a table – something you won’t get from a generic PDF. Need to know the charge pressure for the hydrostatic drive? It’s in the specs. No guessing.

Engine: Instructions and Spare Parts – Two Separate Chapters

Dynapac splits the engine coverage into three chapters: Warranty, Instructions, and Spare Parts. The Instructions chapter (chapter 7) covers the actual service procedures – oil change intervals, filter part numbers, and belt tension specs. The Spare Parts chapter (chapter 8) gives exploded diagrams with order numbers. If you’re swapping a starter on a CA 302, you look up the part number, cross-reference the order number from page 8. No more guessing which starter fits from the shelf. This is the kind of detail that keeps a job from turning into a parts-run marathon.

For standard transmission basics, check Manual Transmission on Wikipedia – but for the Dynapac, stick to the factory book.

Maintenance Interval Schedules – Days, Not Mileage

The Maintenance chapter (chapter 4) is where you spend most of your time. It lists 10-hour, 50-hour, 250-hour, and 1000-hour services with torque specs for the wheel lug nuts and the vibration mounts. I’ve seen guys snap a vibration mount because they used a four-way cross instead of a torque wrench. The manual gives you the values in lb-ft. Follow them. Also, it includes the grease point map for the center joint – overlooked by most DIY guys.

Dynapac User Manual Coverage: Which Models and What’s Inside

This manual covers the CA 252, CA 302, CA 262, CA 362, and CA 402. It’s the same book that came in the dealer’s service kit. If you’ve got a CA 512 or CA 602, the same document covers those as well – the order numbers are listed in the front. The Warranty/Registration section (chapter 1) has the blank forms if you need to file a claim. For the engine, it covers the specific diesels Dynapac used in those years – no guesswork about the injection pump timing.

If you’re working on other compactors, consider the Dynapac C 220 User Manual – Factory Specs for Roller Operation for a smaller tandem model, or the Dynapac CC102C User Manual – OEM Factory Specs & Safety for a different series. Another option is the DYNAPAC CC1000 Operation and Maintenance Manual for larger machines.

For general drivetrain theory, Manual Transmission articles can help you understand the gear ratios, but the Dynapac book has the actual specs for the axle lube.

FAQ

Does the manual include torque specs for the vibration eccentric bolts?

Yes, in the Engine: Instructions chapter.

How do I interpret the spare parts diagrams when the part number is scratched off?

Flip to the Spare Parts chapter. Every diagram has a callout number that links to a table with the official order number (e.g., OMS252EN). You cross-reference that number with the part description – it lists the exact fastener grade and quantity. If the diagram shows a washer that uses a special hardness rating, the table calls it out. I’ve used this method to identify a discontinued hydraulic hose by its bend radius shown in the drawing, then sourced an original equivalent. No aftermarket book will give you that level of detail because they scan from copies and lose resolution. Dynapac printed these direct from the engineering drawings.

Stop wasting time on aftermarket guesswork. Access the Factory Manual – the real 340-page OEM document – and get the specs you can trust on your workbench.
