Dynapac CA 151 Parts Catalog – OEM Factory Parts Breakdown

Spent half a morning once chasing a wrong part number from a third-party catalog for a CA 151 drum bearing. Never again. This is the real deal — the OEM Dynapac CA 151 Parts Catalog, 188 pages, straight from Dynapac Heavy Equipment AB in Karlskrona, Sweden. If you are maintaining a CA 151 vibratory roller, you need factory exploded views and correct part numbers, not some aftermarket reprint that skips half the details. Aftermarket crap like that costs you downtime and reorders. This catalog covers every wearable part from the engine deck to the decals on the platform.

Page 3 lays out the group index: Frame (10), Drum (20), Engine (30), Transmission (40), Hydraulic System (50), Electrical Equipment (60), Driver’s Platform (70), Decals (80), Standard Equipment (90), Optional Equipment (91), and the Numerical Register (100). Each group has a blown-apart illustration with position numbers and a corresponding text page listing quantity, part number, and description. That is how you order the correct bearing, seal, or hose — no guesswork.

Engine Group (Group 30): What the Parts Catalog Covers

The CA 150 – CA 152 series originally used a Deutz F4L 912 or a Cummins 4BT 3.9 diesel. This catalog shows every bolt, gasket, injector line, and mounting bracket. You get the exploded view and the part number. No torque specs here — this is a parts catalog, not a service manual. But if you need a cylinder head gasket, you find the right one by referencing the illustrated breakdown. Do not try to use a generic parts list for these engines; the vibration roller installation uses specific brackets and pulleys that differ from a standard industrial engine.

Transmission and Drivetrain (Group 40): Identifying Replacement Parts

Group 40 covers the transmission (kraftöverföring). The CA 151 uses a hydrostatic drive system. The catalog shows the pump, motor, and gearbox components. When the drive motor seal leaks, you need the exact seal part number. This catalog gives you that. Page references within the group help you cross-check. I always keep this open when I tear into a transmission — one wrong number and you are waiting a week for a return.

Electrical Equipment (Group 60): Wiring and Component References

The electrical section covers the starter, alternator, switches, and the wiring harness segments. Each component has a position number. If your CA 151 loses its charge, you can find the alternator part number in this section. The group includes connections for the vibratory control system. Having the OEM part numbers saves you from buying a generic alternator that does not match the bracket or pulley offset.

Hydraulic System (Group 50): Parts Breakdown

Hydraulic system failures on a roller are dangerous. A burst hose or a stuck valve can drop the drum or cause a runaway. Group 50 shows the hydraulic pump, control valves, cylinders, and all hoses with their part numbers. Use this catalog to order the correct O-ring kit for the vibratory valve. Do not trust a universal O-ring assortment — the factory catalog lists the exact size and material. Page 4 explains how to read the catalog: the picture page has exploded views, the text page lists the parts with quantities and numbers. Every part is referenced back to the numerical register in Group 100 if you have an old part number and need the current one.

Frame and Drum Sections (Groups 10 and 20): Structural Components

The frame group includes the main chassis, engine mounts, and ROPS mounting points. The drum group shows the drum shell, bearings, vibration shaft, and scraper bars. If you are replacing the vibration shaft seal, the exploded view in Group 20 saves you from disassembling the wrong end. The catalog also includes decals (Group 80) — those safety labels often get scraped off. Ordering the correct decal keeps your machine compliant and visible to operators.

Source Authenticity: Why OEM Beats Aftermarket

This catalog is the original factory print, not a scanned copy of a copy. Every part number was validated by Dynapac’s engineering department. Aftermarket catalogs often omit the “optional equipment” group (Group 91) or mix up frame revisions. On the CA 151, serial number 598007 and up have different drum bearing carriers. The aftermarket crap I saw had the old carrier numbers. That would have cost my customer a day of labor. Stick with OEM documentation.

Does this catalog give me torque specs for assembling the drum?

No. This is a parts catalog, not a service manual. Torque values require the factory service manual.

How does the numerical register (Group 100) help me find a part I already have?

If you have an old part number stamped on a component — say a hydraulic hose — you can look it up in Group 100. The register lists every part number in the catalog and shows which group and page it appears on. That way you can verify the part is still current and see the exploded view to confirm fitment before you order. I use this constantly when a machine comes in with worn-out parts and the labels are gone. You cross-reference the number, find the illustration, and order the correct replacement without tearing down the whole assembly.

If you work on these rollers regularly, having this catalog on your tablet or in your shop is a no-brainer. Every exploded view, every part number, every group is organized the way Dynapac intended. Access the Factory Manual from AutoRepairManuals and put the guesswork behind you.
