AGCO Allis AA6.125 2005 Parts Catalog

I’ve seen more tractors torn down because a guy guessed a part number than I’ve seen broken axles. AGCO Allis AA6.125 2005 Parts Catalog is not a service manual. It’s an illustrated parts breakdown that tells you exactly which bolt, seal, or gear you need. No aftermarket cross-reference garbage. Factory-original 535 pages printed in 2005. If you’re rebuilding a hydraulic pump or replacing a transmission bearing, you want the OEM part number from this book, not an internet forum guess.

General Information: What This Section Covers

Section One of the catalog starts with INFORMAÇÃO GERAL – General Information. It explains the part number structure. Each part has a 7-digit code (like 161168M4) plus a figure reference. The example on page 3 shows columns: asterisk indicates a change from the last edition, part code, component numbers, observations, quantities, and description in Portuguese, English, and Spanish. Special notes tell you that an “X” in the quantity column means “as needed.” This is not a repair guide. It’s an ordering document. Use it to get the right part on the shelf before you open a wrench.

Symbols and Notes: Reading the Codes

Flip to the Symbols page and you’ll see what each icon means. The manual uses standard AGCO symbols for things like “service part” or “superseded number.” There’s also a section on ALTERAÇÕES DESDE A ÚLTIMA EDIÇÃO – Changes After Previous Publication. When AGCO issues a bulletin, this catalog tracks the revision. The page footer includes the catalog number CPHYPER E01 and edition date. Manual corrections get inserted as bulletins; new editions roll up all supplements. This is how real OEM documentation works.

Group Index and Numerical Index: Finding Parts Fast

The catalog includes a GROUP INDEX ALPHA and a NUMERICAL PART NUMBER INDEX. If you need steering components, you look up “Steering” in the group index, get a figure number, then flip to Section Two. Or if you already have a part number, the numerical index tells you which figure and row it appears on. This is faster than any parts counter computer system. The index covers every group from engine to chassis to electrical. You don’t need to flip through 535 pages blind.

Illustrations with References: Section Two Breakdown

Section Two is where the catalog earns its keep. Each page has a FIGURA (illustration) with numbered callouts and a corresponding TABLE COM AS REFERÊNCIAS (part number reference list). Every bolt, nut, washer, gasket, hose, and bracket is shown. The table includes quantities, descriptions, and the part number. For example, a differential kit shows item 1 as kit 161168M4, item 2 as crown wheel 361901M1, and item 3 as pinion. This level of detail stops you from ordering the wrong internal gear.

Why Factory OEM Documentation Matters

Aftermarket parts catalogs often combine multiple model years or skip revisions. This one is the exact bulletin set that AGCO Allis issued for the AA6.125 tractor in 2005. It’s multilingual (Portuguese, English, Spanish, French) because these tractors sold globally. The part numbers are direct OEM – no cross-reference needed. When you order a part using this catalog, you get the piece that fits. I’ve seen a guy install a wrong bearing because he used an aftermarket catalog that didn’t show the update after a revision. That cost him two days and a ruined gear set. Trust the factory print.

Audience Fit: Who Needs This Catalog

If you own an AA6.125 and do your own repairs, you need this. If you run a small tractor shop, put a copy on the parts counter. Beginners: don’t try to order parts by guessing. This catalog is for anyone who wants the correct fastener or seal without pulling the old one and measuring it. It’s also useful for restorations – you can identify missing parts and locate them. The agricultural community around San Antonio uses these tractors for hay fields and small farms. You don’t want downtime waiting for the wrong part.

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and illustrates assemblies. Torque specs are in the service repair manual.

How is the part number structure organized?

Each part gets a 7-digit code (e.g., 161168M4) with a figure reference. Columns indicate whether the part has been revised (asterisk), its component relationship, quantity, and description in four languages. The bottom of each page has the catalog number, edition, and generation date. Supplements are issued for new or revised pages; the edition number increments.

Can I use this catalog for the AA6.150 or AA6.190?

No. Each model has a separate parts catalog. The AA6.125 shares some components with other models, but the part numbers and illustrations are specific to this chassis. For the AA6.150, see the AGCO ALLIS TRACTOR AA6.150 Parts Catalog 2007. For the AA6.190, use AGCO ALLIS TRACTOR AA6.190 Parts Catalog 2007. For the AA6.220, get AGCO ALLIS TRACTOR AA6.220 Parts Catalog 2007.

Is the manual in English?

Yes. The catalog is printed in Portuguese, English, Spanish, and French. All part descriptions and tables are multilingual. The headings are in Portuguese but the symbols and numbers are universal. English-speaking users can navigate using the numerical index and figure callouts without needing translation.
