John Deere 918, 920 1998 Parts Catalog

If you’ve ever tried to order a replacement auger bearing for a 918 or 920 draper platform using a third-party parts list, you know the pain. The serial number breaks are wrong, the part numbers don’t match, and you end up with a box of hardware that fits nothing. That’s why I don’t touch aftermarket parts catalogs. The John Deere 918, 920 1998 Parts Catalog is the factory-issued document that Deere dealers use. 131 pages of grid-indexed parts breakdowns, grouped by assembly, with serial number ranges down to the last digit. No guesswork.

Grid A: Frame and Front Attachments

The catalog is organized into grids A through F, plus L. Grid A covers the frame, hitch, and front shields. If you need a new torque tube or leveling rod, you’ll find the exploded view under A02. Page 2 shows the serial number plate location—critical information before ordering. Use the correct serial number, or you’ll get the wrong part. Every assembly includes a note like ‘918 ( -635900)’ or ‘920 (646301-656300)’ so you know which revision fits. For related cutting platform parts, see the John Deere 900 Series Cutting Platform Parts Catalog.

Does This Manual Cover the Auger Drive?

Yes. The auger drive sections appear under Grid C and Grid E. You’ll find separate listings for 918 and 920 depending on serial number range. The index includes ‘Auger Drive 920 (646301-656300)’ and ‘Auger Drive 920 (656301-666300)’ among others. If you’re rebuilding the cross auger, the part numbers for bearings, shafts, and fingers are all there. No need to cross-reference aftermarket tables.

3 Critical Sections for Draper Maintenance

First, Grid B: reel arms and cutterbar. The ‘Bolted Knives and Guards’ section for 918 gives you the exact blade and guard part numbers. Second, Grid D: draper and belt drives. You’ll see the roller and idler assemblies. Third, Grid F: hydraulic components. Those sections alone save you hours of hunting through generic agricultural parts lists.

Verify Serial Number Before You Order

Look at page 2 of the catalog. The serial number plate is on the left-hand side of the frame for 918 platforms. For 920, the same applies. The format is H0 + model + configuration suffix + sequence number. Use that number when referencing any grid. If you skip this step, you’ll order parts for a 918 built before 635900 when your machine is a later build. That’s a wasted trip. The manual also cross-references to John Deere 4500, 4600, 4700 2000 Parts Catalog – OEM Grid Index for related platform components.

Alphabetical Index: Finding Parts Without the Grid

The back of the catalog includes an alphabetical index from A to L. Need ‘Auger Fingers – 920 (656301- )’? Look under A. The index directs you to the grid and the specific part number. This is faster than flipping through grids if you know the part name. But verify the serial range—many parts have multiple entries based on production changes. If you’re curious about the diesel engines that power the tractors pulling these platforms, read this Wikipedia article on diesel engines for general background and this Wikipedia article on diesel engines for technical details.

Aftermarket catalogs copy the grid numbers but often omit the serial number breaks. That’s how a rookie ends up ordering a reel arm for a 920 built after 656300 when his machine is a 646301-656300 build. This factory catalog gives you every revision.

Does this parts catalog include repair procedures or torque specs?

This is a parts catalog only. It lists part numbers, not repair steps or torque values. For service procedures, get the technical manual.

How do I find the correct part for my 920 with serial number 656301?

Look in the alphabetical index for the part name, e.g., ‘Auger Drive 920 (656301-666300)’. Note the serial range that includes your number. Then go to the grid indicated (e.g., C14). The exploded diagram shows the part with the key number. Match that key number to the parts list for the correct OEM part number. Always cross-check the serial number note at the top of each grid page. Deere often revises parts mid-production, so using the wrong range will give you the wrong revision. The catalog is accurate as of 1998, but later revisions may exist—check the latest service bulletin if your machine is newer.

If you’re tired of ordering wrong parts and wasting money, stop using aftermarket lists. Access the Factory Manual from AutoRepairManuals—it’s the same one John Deere dealers pull up on their screens.
