Ammann AC110-3N Parts Catalog – What a Real Mechanic Sees

You are tearing down an AC110-3N that came in with a busted hydraulic line and a burnt-out solenoid. The machine has been sitting for two months because the shop before you ordered the wrong steering cylinder seal twice. That is what happens when you rely on aftermarket parts lists that copy from a copier of a copy. The Ammann AC110-3N Parts Catalog I am about to describe is the black-and-white, 160-page binder that kills that guessing game. It is printed from the original Ammann Schweiz AG files – no translations lost, no re-drawn diagrams. If you need a part number for a seal, hydraulic hose, or electronic control box, this is where you start.

Safety First: Battery Disconnect Before Welding

Flip to the first few pages – there is a big boxed warning in German, English, and French: “Bei Schweissarbeiten an der Maschine muss die Batterie abgehängt werden.” That means disconnect the battery before any welding on the machine. Ammann knows that the electronic control unit will take a spike from the welder and die. Same warning applies to water jets – never spray directly onto electronic components. This is not a suggestion; it is a printed instruction from the factory that you need to show to any welding sub. Skip that step and you are buying a new ECM.

Parts List Structure: How to Read It

The catalog is organized by assembly groups, from the Cummins engine to the vibration drum. Each page is an exploded diagram with reference numbers that tie to a table on the facing page. The tables give you the Ammann part number, the description, and the quantity. You also get the revision index – look for index B on the cover, meaning this version covers serial numbers from 1000 onward. If your machine is older than serial 1000, you need a different catalog. Check the serial plate before you order anything.

7 Systems Covered by the OEM Manual

The catalog splits the AC110-3N into major systems: engine, hydraulic pump and motor, vibration system, steering, water spray, electrical/electronic, and frame/canopy. Each section has its own index page with thumbnail diagrams so you can find the right assembly without flipping through 160 pages blind. Need the charge pressure relief valve part? You will find it under the hydraulic section, grouped with the pump. No cross-referencing a third-party database that guesses the thread size.

Hydraulic Hose and Fluid Warnings

Page 4 of the catalog carries a caution about hydraulic hoses. If the machine has been running on synthetic ester hydraulic fluid (HE), you cannot just swap in any hose. The replacement must be approved by the supplier for use with synthetic esters. And Ammann explicitly forbids converting a used machine to biodegradable fluid – it is a “Verboten” warning in bold. That tells me the factory has seen seal failures from that swap. If you are working on a rental fleet that wants to switch fluids, you need to follow this OEM caution, not a salesman’s pitch.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, the part numbers are direct from Ammann’s own system – you will not get a “equivalent” that has the wrong thread pitch. Second, the safety warnings are original, not summarized or omitted. Third, the layout matches what your dealer looks up – when you call Ammann with an OEM part number from this catalog, they will not argue with you. I have seen aftermarket parts catalogs that combine a dozen models into one PDF and get the illustrations backward. Paying for the real thing up front saves a return shipping charge later.

For related machines, the Ammann AC110-2 Parts Catalog – 182-Page OEM Spare Parts Manual covers the previous generation, and the Ammann Rammax 1515-M/MI/MC/MCI 2010 Parts Catalog – OEM Factory Manual works for the smaller walk-behind rollers. The Ammann ARX 90 2013 Parts Catalog – 328-Page OEM Spare Parts is the one you need if you step up to the larger single-drum model. Keep them all on the same tablet so you don’t mix up part numbers across families.

If you’re unfamiliar with the industry, you might want to read the Automotive Industry Overview for context on how heavy equipment parts distribution works. Also check the Automotive Industry Overview for more background – but honestly, you already know that Ammann builds rollers in Switzerland, and their parts catalogs are not toys.

Does This Catalog Cover the Cummins Engine?

Yes. The AC110-3N uses a Cummins diesel – the catalog has a dedicated section with the engine exploded view and all serviceable part numbers including the injector pump, filters, and gaskets. It does not give you overhaul torque specs, though; that is what the service manual is for. This is a parts catalog, not a service manual. You need the parts catalog to order the correct piston rings and the service manual to know the ring end-gap. Keep them together.

What is the difference between this Parts Catalog and a Service Manual?

The Parts Catalog gives you exploded diagrams and part numbers. It does not contain procedures, torque specs, or troubleshooting. That is the service manual. You need both for a full overhaul.

Does the catalog include hydraulic hose lengths and fittings?

Yes. Each hydraulic hose is shown in the diagram with the exact Ammann part number and the length code. No need to measure the old hose if the crimp fitting is still legible.

My roller has serial number 998 – will this catalog work?

The cover states serial number 1000 and up. The catalog indexed with “B” revision may not cover early machines. You need the version that matches your serial number range. Call the dealer to confirm.

Are the part numbers still current?

This is the original factory catalog file, printed around the time the machine was built. Some parts may have been superseded. Always check with Ammann before ordering. The catalog gets you the starting point.
