Dynapac CA 251, CA 301 Parts Catalog – 294-Page OEM Factory Breakdown

You’ve got a roller down, and the parts counter guy reads you a number that doesn’t match anything on the machine. That’s the kind of headache this Dynapac CA 251, CA 301 Parts Catalog kills. 294 pages of OEM exploded views and part numbers – no aftermarket re-drawings, no guessing. If you need a bearing for the drum or a seal for the hydraulic pump, this is the document your parts order relies on. I’ve been wrenching long enough to know that a wrong part costs double: the return fee and the downtime. This catalog eliminates that.

It covers both the CA 251 and CA 301 vibratory rollers, with valid serial number ranges right on page 3. Diesel engine options are Deutz F6L 912 and Cummins 6BT 5.9/C. The whole thing is organized by assembly groups – frame, drum, engine, transmission, hydraulics, electrical – each with its own section and page range.

Frame Ram (10) and Drum Vals (20): Start Your Identification Here

Section 10 diagrams the main frame and ram components. Section 20 breaks down the drum assembly including bearings, seals, and vibration system parts. If you’re replacing a drum motor or a center bearing, these pages give you the exact OEM part number. Don’t rely on aftermarket cross-references – one wrong spline count and you’re pulling the drum again. Use the original factory drawings.

Engine Motor (30): Deutz and Cummins Details

Page 30 kicks off the engine section. It lists every gasket, injector line, and pulley for both the Deutz and Cummins powerplants. The parts catalog doesn’t show repair procedures – that’s what the service manual is for – but it gives you the part numbers to order before you even pull the engine. Check the DYNAPAC CA 251/301 Instruction Manuals Index for torque specs and service intervals; here you get the parts breakdown.

Transmission (40): What’s Covered

Section 40 covers the transmission and driveline. Gears, shafts, shift forks – it’s all diagramed with callouts. The catalog also includes the connecting parts to the drum and axle. If you’ve got a transmission leak, you can pinpoint the exact seal or gasket number without pulling the unit apart first.

Hydraulic and Electrical: Two Systems You Cannot Guess

Section 50 is the hydraulic system – pumps, valves, hoses, fittings. Section 60 covers the Electrical equipment, including the wiring harness and switches. The DYNAPAC CA 251/301 Spare Parts Catalogue includes the same numbering as the manufacturer’s own system, so you can order direct from Automotive Industry Overview standards, but the parts are specific to Dynapac. Don’t substitute without checking the part number index.

Part Number Index: 294 Pages of Cross-Reference

Page 100 starts the numerical part number index. All 294 pages lead to this – a sorted list of every part number in the catalog with the page and section where it appears. Lost a bracket on the driver’s platform? Look up the number in the index, flip to section 70, and order the exact piece. The index saves hours of leafing through sections. It also includes standard equipment (section 90) and optional equipment (section 91) like ROPS or special lights.

Why OEM Print Beats Aftermarket

This is an original Svedala Dynapac publication, printed in Sweden in 1997. The Dynapac factory specs haven’t been reinterpreted by a third party. Aftermarket parts catalogs often use generic drawings or miss superseded numbers. This one has the actual safety-part symbols (page 4) that flag critical components – bolts, pins, hydraulic lines that must meet factory strength. If a part is marked as a safety detail, you don’t sub it out. The catalog tells you which ones those are.

Can I use this catalog to repair my roller?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers only. For repair procedures and torque specs, get the corresponding Instruction Manuals Index.

Does the part number index cover all 294 pages?

Yes, the index on page 100 lists every part number that appears in sections 10 through 91. It’s sorted numerically, so you can find any component’s location in seconds. If you have the old part number from a previous catalog revision, cross-check with this index to see if it was superseded – the catalog’s serial number range on page 3 tells you which machines it applies to. CA 251 from *58310252* and CA 301 from *59010302*.

If you’re keeping a Dynapac CA 251 or CA 301 on the job, this is the document that keeps parts ordering straight. Access the Factory Manual from AutoRepairManuals and put it in your tool crib. You’ll thank yourself the next time a hydraulic hose blows.
