Ammann ASC 250 Parts Catalog – 387-Page OEM Spare Parts Manual

I’ve had more than a few guys roll into my bay holding a parts catalog that looks like it was printed from a blurry fax. They bring the wrong seal, wrong hose, wrong pump, and then wonder why the machine won’t go together. That doesn’t happen when you’re working off the factory Ammann ASC 250 Parts Catalog. This is the same document the dealer uses to look up part numbers – 387 pages of exploded views, reference numbers, and OEM ordering instructions. If you’re maintaining an ASC 250 vibratory roller, this is the only parts list you should trust.

Engine Section: What the Catalog Covers for the Cummins Motor

Section 105 A and 105 B cover the MOTOR CUMMINS in full detail. You get two sub-sections (105-36 being the main engine breakdown) with every gasket, bolt, injector, and filter listed by Ammann’s own part number. No cross-referencing third-party catalogs that guess at the factory spec – this is the exact list from the assembly line. If you need to order a new fuel filter or an entire long block, the exploded view shows you exactly how each piece fits and what number to give the parts counter.

Hydraulics: FAHRAUWIEBSHYDRAULIK and VIBRATORHYDRAULIK

Pages 300 A and 300 B get into the travel hydraulics – pumps, motors, lines, and fittings. Then section 320 covers the vibrator hydraulic circuit. I’ve seen guys order a motor for the wrong function because the aftermarket catalog used a generic photo. This catalog breaks it down by system: travel, vibrator, steering (section 334), and blade hydraulics (section 345). Each hydraulic component has its own sub-number so you can confirm you’re buying the right pressure line or cylinder rebuild kit. The ordering instructions on the first few pages explain how to decode the serial number and machine variant – critical for hydraulic parts that changed between production runs.

Electrical: ELEKTROINSTALLATION and Cabin Wiring

Section 407 (ELEKTROINSTALLATION) and 410 (ELEKTROINSTAL KABINE) give you the wiring layout for the entire machine. Headlights, warning lights, horn, tachometer – everything has a callout. If you’re chasing an electrical gremlin, the parts catalog won’t give you a wiring diagram the way a shop manual would, but it will tell you the exact plug, relay, and fuse part numbers. I’ve used this to order a replacement switch for the front lights (section 421) without pulling the whole harness apart. Combine this catalog with the shop manual and you’ll have the full picture.

Read the Ordering Instructions Before You Call the Dealer

The first few pages after the cover – pages 3 and 4 – contain the official instructions for ordering spare parts in seven languages. The manufacturer specifically warns that if you install parts using procedures outside those in the shop manual, they aren’t responsible for damage. That’s not just legal CYA; it’s a reminder that the parts catalog is a reference tool, not a repair guide. Treat it that way. When you call Ammann or your local dealer, have the serial number (found on the machine plate) and the part number from this catalog ready. It saves time and cuts down on wrong orders.

Why OEM Beats Aftermarket Every Time on This Machine

Aftermarket parts catalogs often take photos from an early production model and apply them to later serial numbers. This Ammann ASC 250 Parts Catalog is the genuine factory release – see the Ammann logo and “ACZ 02/06” date code on the first page. The part numbers change when the engineering team updates components. The catalog reflects those revisions. I’ve had to warranty jobs because a generic list gave me a bolt with the wrong thread pitch for the vibrator mount. That’s time you don’t get back. Stick with the OEM document.

Frequently Asked Questions

Can I use this parts catalog to do repairs, or is it only for ordering parts?

It’s a parts catalog, not a shop manual. You get exploded views and part numbers, but no torque specs or removal procedures. Use it alongside the factory shop manual for repairs.

How do I know if a part from an earlier serial number fits my ASC 250?

The catalog is organized by machine serial number range – see the note on page 3 (the “Serial Nr. 16-” line). Ammann updates the part numbers when changes occur. If your serial number falls after the break, use only the numbers listed for your range. Mixing them up can cause fitment problems, especially in the hydraulic and engine sections. I always write the serial number on the cover page before I start ordering. It’s saved me from buying the wrong steering cylinder twice.

Stop guessing which part fits. 387 pages of factory data means every bolt, hose, and motor is listed with the correct Ammann number. If you want to keep your ASC 250 running without wasting time on returns, Access the Factory Manual now.
