New Holland 8070, 8080 1979 Parts Catalog

If you’re wrenching on a New Holland 8070 or 8080 combine from the 1979 model year, you need a parts catalog that shows you exactly what goes where, with the factory part numbers, not some aftermarket artist’s rendering. This is the real thing—269 pages of OEM breakdowns, straight from the Zedelem plant. I’ve been in this trade for 28 years, and I can tell you: when you’re hunting for a hydraulic brake shaft or a stone trap bracket, the difference between a correct part number and a “close enough” guess is the difference between a running combine and a weekend wasted on returns.

7 Systems Covered – From Brakes to Unloading Reel

This catalog breaks the New Holland 8070 and 8080 into 7 major system groups: belts & chains, straw handling, operator platform, drivetrain, hydraulics, harvesting components, and final drives. Each group is further split into left-hand and right-hand assemblies where applicable. You get exploded views for every subassembly, plus the corresponding part numbers, quantities, and any special notes like “AR” (As Required) or “NSS” (Not Serviced Separately). Need to find the brake pedal linkage? That’s in Group 16 and 17. The brake assembly itself is Group 42. The indexing is done by pictorial index—look at the picture, find the group number, flip to the page. No guesswork.

Hydraulic Brake Shaft Assembly – Real-World Use Case

You’re a home garage mechanic with a 8080 combine that’s lost brake pressure. The pedal goes to the floor. You pull the floorboard and see a line leaking near the hydraulic brake shaft. Without this catalog, you’re pulling random fittings and hoping. With it, you flip to Group 14 (Hydrostatic steering drive) and Group 17 (Circuit for hydraulic brakes). The exploded diagram shows the exact shaft, the bushings, the seals, and the hardware. You order the correct part numbers—no trial and error. That’s the difference between one trip to the dealer and three.

Source Authenticity: OEM vs. Aftermarket Documentation

I’ve said it a hundred times: aftermarket parts catalogs are a gamble. They’ll redraw a diagram from memory, miss a fastener, or renumber a part. This New Holland 8070, 8080 1979 Parts Catalog is a direct scan of the factory-issued document—printed in 1979, multilingual, with the official New Holland part numbers. The abbreviations are the same ones the dealer uses: “CD” for check digit, “w/a” for welded assembly. If you’ve ever ordered a part from a third-party book and got a wrong shipment, you know the pain. This manual eliminates that. Refer to the Automotive Industry Overview to see how OEM specs maintain consistency across decades.

Does This Catalog Cover the Unloading Reel and Hydraulic Lines?

Yes. The catalog includes Group 104-115 (Unloading reel and hydraulic) and Group 40 (Hydraulic lines). For the hydrostatic drive version, the hydraulic filter and reservoir are Group 39. For the mechanical drive, hydraulic equipment is Group 46. Every line, fitting, and seal is listed with dimensions—tube sizes in millimeters and inches, straight lengths available as service parts. If you need a pre-bent tube that’s no longer available, the catalog tells you what straight stock to buy and how to cut it. That’s the kind of detail that saves you a welding job in the field.

3 Groups Every Owner Should Bookmark

If you own a 1979 New Holland 8070 or 8080, bookmark these three groups: Brakes (Group 42), Hydraulic valve (Group 26), and Transmission gearbox (Group 41). Those are the high-wear areas that combine owners call me about. The brake group shows the discs, seals, and return springs. The hydraulic valve group shows the three-way valve and its seals. The transmission group shows all the gears and studs. Having these pages printed out and laminated in your toolbox is cheap insurance.

FAQ

Does this catalog include torque specs for the brake assembly?

No. This is a parts catalog, not a service manual. It shows exploded diagrams and part numbers, but does not list torque values or assembly procedures. For that, you need the separate service manual.

Can I use this catalog to order parts for a 1980 model 8070?

This edition is valid from machine serial numbers listed inside. It replaces previous issues. If your 1980 machine falls within the serial range, the part numbers will match. Check the serial number prefix on page 1. If your machine is newer than the catalog’s validity range, you may need a later supplement.

Stop chasing ghosts with aftermarket diagrams. Grab the real OEM document. Access the Factory Manual and get the part numbers that match your combine.
