John Deere 25 1989 Parts Catalog

I’ve seen guys order the wrong decal kit three times in a row because they went off a memory of what the sticker looked like. That’s $150 and a weekend shot. If you’re working on a John Deere 25 combine header transport frame from 1981 through 1985, you don’t need guesswork — you need the actual grid index. This Parts Catalog from 1989 gives you the factory part numbers straight from the Deere engineering drawing. No reprint. No third-party abridgment. 13 pages of what actually bolts onto that frame.

Serial Number Plate Location – Page 2

The first thing most people screw up is ignoring the serial number. This manual puts it front and center: the plate is on the front cross beam. Without the serial number you’re ordering parts for someone else’s frame. The catalog lists part applicability with ranges like 1501- or -000000. If there’s any xxxxxx in the serial column, that means Deere made a change during production and the exact number wasn’t recorded when the catalog went to print. You’ll still get the right part if you read the footnotes.

Bolt Strength Identification – SAE Grade 8 vs Grade 5

Page 3 spells out the difference clear as day. Bolts and cap screws that need high-strength qualities equivalent to SAE Grade 8 are marked HS SAE 8 in the catalog. Everything else is Grade 5 or lower. On a header transport frame that’s hauling a combine head down a highway, you absolutely need Grade 8 for the hitch bolts. If you sub in a Grade 5 because that’s what you had in the drawer, you’re asking for shear failure at 65 mph. The manual tells you which is which. Use it.

Decals, Emblems, and Slow Moving Vehicle Sign – Alphabetical Index

The index lists DECALS on page 10, EMBLEM – SLOW MOVING VEHICLE right after. If you’re restoring a frame or need to pass a DOT inspection, the reflective SMV emblem and the warning decals have their own part numbers. Don’t buy a generic kit — the Deere decal kit has the exact adhesive and UV resistance specs. The alphabetical index also covers KIT, DECAL so you can order the whole set without hunting through 50 pages.

Frame and Hitch – Section F

Section F covers F02 through F08 and F25. That’s the main frame rails, the hitch bracket, the light bar bracket, and the wiring harness brackets. If you’re replacing the tongue or the clevis, you need the F-section exploded views. The grid numbering system means you find the part by coordinates, not by flipping pages randomly. Once you locate the illustration, the key number references the parts list with the correct quantity and finish. Works even if you’re standing in a dusty barn with a flashlight.

Why OEM Documentation Beats Aftermarket Copies

I’ve had three different aftermarket catalogs try to sell me a wiring harness bracket that was for the wrong continent. This manual lists separate part numbers for France-built frames — see LIGHT BAR, TRAILER (FRANCE) and WIRING HARNESS BRACKETS (FRANCE) in the index. Aftermarket reprints either omit those or merge them into one generic bracket that doesn’t fit. The OEM grid index also includes the change indicator line in the left margin, so you can see what was revised after the original print date. You can’t get that from a scanned PDF that some guy photoshopped.

3 Reasons to Choose This 1989 OEM Parts Catalog

• Serial number cross-referencing – Every part tied to a production range. No guesswork on supersessions.
• Bolt strength callouts – HS SAE 8 vs standard Grade 5. That’s a safety issue, not a preference.
• Complete goods listings in bold – Bold-face type means order separately as a complete assembly, not individual pieces.

Who Needs This Manual

If you own a 25 series combine header transport frame — whether it’s a barn find, a fleet unit, or a daily hauler — you’re the guy. Home garage guys who insist on doing their own repairs will save the headache of ordering wrong parts. Dealership parts countermen use this exact catalog to look up numbers. It’s the same document that was on the shelf at your local John Deere dealer in 1989. Nothing’s been changed, abbreviated, or simplified.

Frequently Asked Questions

Does this manual include torque specifications for the hitch bolts?

No. This is a parts catalog, not a service manual. It tells you which bolt to order (part number, grade, length), not how tight to torque it. For torque specs on the header transport frame, look at the separate OEM technical manual for the 25 combine.

Can I use this to identify parts on a frame built after 1985?

This catalog covers frames manufactured 1981-1985. Frames built later might have different part numbers even if they look identical. Always verify the serial number against the listing on page 2. If your frame’s serial number is higher than the last number shown, you need the updated catalog from the later production year.
