Deutz Fahr 5680 Parts Catalog – Factory Parts List PDF

Years in the shop have taught me one thing: if you’re ordering parts for a combine without factory part numbers, you’re going to waste money on the wrong stuff. The Deutz Fahr 5680 Parts Catalog is the only document I trust when a 5680 rolls in needing a chopper rebuild or a chaff spreader swap. This isn’t some aftermarket rewrite – it’s 32 pages of OEM exploded views with Deutsch‑Fahr’s own reference codes. You want the right knife set for the KPAB straw chopper? Page 2 has the 4U.36.1 drawing with all dimensions. That’s the difference between a Saturday job and a two‑week wait for a return.

KPAB-Straw Chopper Assembly: What’s Covered

The index splits the chopper into three subgroups: knives (4U.36.1), V-belt (4U.36.2), and the frame assemblies. Each section includes the exact part number for every bolt, bearing, and guide roller. The KPAB‑STRAW CHOPPER BASIS FRAME (4U.36.102) drawing shows mounting holes and weld points – handy when a frame cracks from a rock strike. Also listed: the distributor box (4U.36.103) and its electric regulation unit (4U.36.104). If your machine has the SRX option, you get separate entries for the SRX‑only frame (4U.36.109) and distributor box (4U.36.110). No guessing whether a part fits.

Knives and V-Belt: Specific Part Numbers

Knife section lists every blade in the set with its length and thickness. The V‑belt entry gives the cross‑section and effective length – vital when you’re matching aftermarket belts to the OEM spec. One wrong groove angle and the belt slips off within an hour. This catalog eliminates that. The diagram on the knife page (page 2) marks wear limits; you can compare a used blade against the factory profile without measuring. That’s the kind of detail a parts counter can’t give you over the phone.

SRX Variant Differences: Not Just a Trim Level

Owners of the 5680 with the SRX package often assume the chopper parts are identical to the base model. They aren’t. The catalog dedicates six sections to SRX‑only components: mounting frame (4U.36.112 and 4U.36.113), deflector sheets (4U.36.114), and vee belt clutch (4U.36.115). If you order a standard basis frame for an SRX machine, the bolt holes won’t line up. I’ve seen that mistake cost a farmer two days of downtime. The catalog makes it impossible to mix them up because the SRX part numbers start with a distinct prefix.

Parts Catalog Structure: 32 Pages of Factory Drawings

Thirty‑two pages doesn’t sound like a lot until you realize each page is a dense exploded view with 10–15 callouts. The chaff spreader section alone covers four variants (4U.36.118 through 4U.36.122), including the Heuling brand spreader. Every sheet shows fasteners, torque specs for the mounting bolts, and clearances for the spreader vanes. The index at the front is page numbered so you can jump straight to the assembly you need. No flipping through generic diagrams that sort by alphabetical name – this follows the factory build sequence.

Why Dealer Documentation Matters

Aftermarket parts catalogs often redraw the illustration and lose the subtle indicator marks – like which side of the V‑belt pulley faces forward. This is the original PDF from Deutz Fahr, not a scan of a reprint. The lines are sharp, the part numbers are legible, and the callout arrows point exactly where they should. Cross‑referencing with FAHR HD 300 Parts List or the Deutz Fahr Raps Parts Catalog (Cutting Table) gives you the bigger picture of the whole combine driveline. The Deutz Fahr M2680 Parts Catalog Index also shares the same indexing format, so you can move between manuals without re‑learning the system.

Outside the barn, understanding how manufacturers structure parts documentation is a skill that carries over to other equipment. The Automotive Industry Overview uses similar exploded‑view conventions. And if you’re new to reading parts books, the Automotive Industry Overview article can help you interpret callout numbers.

Does the catalog include exploded views for the hydraulic system?

No. This is a parts catalog focused on the chopper and accessories. Hydraulic pumps and valves are not covered. You need the service manual for that.

Can I use this to order parts for a 5680 with the SRX package?

Yes. The catalog has separate sections for SRX‑only frames, distributor boxes, regulation units, mounting frames, deflector sheets, and vee belt clutches. Look for the “FOR TYPE SRX ONLY” label in the index.

What page shows the chaff spreader for the Heuling system?

Pages near the back – reference numbers 4U.36.118 through 4U.36.122. Each Heuling spreader has its own drawing with part numbers for vanes, motors, and mounting brackets. Check the index for exact page numbers as the PDF is not sequentially paginated.

Are torque values listed for the chopper mounting bolts?

Yes, they appear on the basis frame drawings (4U.36.102 and 4U.36.109). Always verify with the factory spec – do not guess.

Before you order one more set of knives or a belt that fits “close enough,” get the original factory breakdown. Access the Factory Manual and keep it on the tablet in the cab. That 32‑page file will save you the headache of wrong parts and the trip back to the dealer.
