AGCO 5100 2005 Parts Catalog

You got a combine header down in the field, and the local parts house hands you a generic break-down they printed off some online forum. That’s how you end up with a wrong auger drive sprocket and a customer chewing you out. I’ve seen it a hundred times. The AGCO 5100 2005 Parts Catalog puts an end to that. This is the exact factory book AGCO shipped to dealers – 277 pages of exploded diagrams, part numbers, and assembly breakdowns for the 5100 Draper Header (25, 30, and 36 foot models). No reprints, no aftermarket scans. You get the same schematics the factory technicians used when building these headers.

What’s Inside This 277-Page Parts Catalog?

Nine clearly marked sections. Section 1 is general info and the alphabetical index – that alone saves you time hunting for a part. Sections 2 through 9 cover drives, adapter, electrical, sickle, draper, header frame and shields, hydraulics, and decals/kits. Every major assembly is broken down into individual components with callouts and reference numbers. Need the electrical harness for a 36-foot header? Flip to section 4 – pages 4-2 through 4-7 show the electrical assembly and harness service parts. That’s the real wiring, not some generic diagram. The hydraulic motor for the reel drive? It’s on the gearbox assembly pages in section 2. You get the part number, the quantity needed, and the exact orientation for installation.

Electrical Systems: Wiring Harness and Assembly Diagrams

Section 4 is dedicated entirely to electrical. Three separate spreads: electrical assembly pages 4-2/4-3, another assembly view on 4-4/4-5, and electrical harness service parts on 4-6/4-7. If you’re chasing a short in the reel fore-and-aft electric kit (pages 9-60 through 9-63), you need these diagrams to trace wires back to the correct connectors. The catalog shows the harness routing and the exact connector part numbers. Using aftermarket electrical parts on a combine header is asking for intermittent failures – the OEM catalog gives you the factory wire colors and pin locations. Don’t guess.

Finding the Right Part Number – The Alphabetical Index

The index at the back (starting on the second page of the book) lists every major assembly alphabetically – Adapter Mounting, Auger Assembly, Canvas Deck, Clutch, Gearbox, Hydraulic Cylinder, you name it. Each entry gives the exact page range. For example, “GAUGE WHEEL KIT (FIXED) 9-36, 9-37” tells you exactly where to look. That kind of organization is missing from third-party PDFs that just dump raw scans. This catalog was designed so a busy technician can find a part in under a minute. Pair it with a related manual like AGCO GC54G Parts Catalog – 15 Pages of Factory Part Numbers if you need something smaller.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs often re-draw diagrams and re-number parts. I’ve seen them swap left and right sides, or miss a washer that’s critical for proper bolt preload. AGCO printed this catalog in 2005 under copyright – every part number traces back to the original engineering release. When you order a “REEL DRIVE HYDRAULIC MOTOR ASSEMBLY” from section 2, you get the factory number that matches the AGCO supply chain. That matters when a dealer looks up your order.

Who Needs This Catalog?

If you own a 5100 Draper Header (2005 or similar), you need this book. If you’re a shop owner with a row of them coming in for preseason prep, you need a copy on every tech’s tablet. The hydraulic section alone – pages 8-10 through 8-25 – covers reel cylinders, slave cylinders, conveyor drives, flow control valves. Trying to rebuild a canvas drive motor without the exploded view? You’ll end up with leftover parts. The sickle section (section 5) gives you the complete cutterbar assembly breakdown. I’ve used these exact pages to order sickle sections for a 36-foot header – the part numbers matched the old GM parts box I had in the corner.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are found in the factory service manual.

Can I use this to rebuild the draper header?

Yes, for identifying every bearing, roller, and chain link. You get the OEM part numbers for the deck assemblies (left/right, 25/30/36 foot), draper assemblies, and mounting brackets. Rebuilding without this is guessing.

Is this the same as a service manual?

No. A service manual includes procedures, clearances, and torque values. This catalog gives you exploded diagrams and part numbers only. You need both books to do a full overhaul. The catalog ensures you order the correct parts; the service manual tells you how to install them.

What years and models are covered?

2005 model year 5100 Draper Headers in 25, 30, and 36 foot widths. The combine adapter section covers mounting to multiple combine models – check the alphabetical index under “Adapter Mounting” for compatibility.
