John Deere 4630 1996 Parts Catalog – Factory Specs for Real Parts

If you’ve ever spent half a Saturday chasing a part number that turned out to be the wrong seal, you know what I’m talking about. Aftermarket catalogs guess. Factory documentation doesn’t. That’s why I keep a copy of the John Deere 4630 1996 Parts Catalog on the bench next to the torque wrench. 856 pages of what John Deere actually built, not what some third-party decided to print. Every grid, every index, every serial number break — it’s all there because Deere put it there.

Decode the Serial Number: Which 4630 Do You Have?

First thing you do when a 4630 rolls in is check the serial plate. The catalog starts with that. Page 2 shows the tractor serial number format: H for Quad-Range, P for Power Shift, W for Syncro-Range. Then the engine serial number on page 3 — six cylinders, 404 cubic inches, turbocharged and intercooled. The short block serial number is stamped into the block near the old plate; page 5 shows exactly where to look. If you miss that step, you’re ordering parts for the wrong build date. I’ve seen guys install the wrong clutch pack because they skipped it. Don’t be that guy.

Grid Index Structure: Three Minutes to Any Part

The catalog uses a grid system. Each section is broken by assembly — 01A, 01B, 01C right through 01F, then 02B, 02C, and so on. You don’t flip through 856 pages guessing. Need the front axle parts? Look up grid 01F. The index at the back of each section tells you exactly which figure and key number to use. I teach my junior techs to mark the grids they use most with sticky tabs. Saves me from hearing “where’s the steering gear” every Monday morning.

Short Block Identification for Engine Overhauls

When you’re rebuilding the 404 diesel, the short block serial number is critical. The catalog lists replacement short blocks with the prefix RG SB. Pages 4–5 give you the production date code and component sequence. You’ll see things like RE603860295 — that’s a service part number with a month and year of assembly. If you order a short block without checking that number, you might get the wrong ring pack or rod bearing. I’ve seen it. The factory catalog stops that before it starts.

OEM Documentation vs Aftermarket Reprints

I don’t trust aftermarket parts catalogs. They copy old images, miss updates, and sometimes swap part numbers because they think “it’s close enough.” This is the genuine John Deere publication — printed by Deere & Company in 1996, with all rights reserved. The serial number plates, the engine codes, the grid figures — they came straight from the Moline, Illinois design office. If you need to know the correct hydraulic filter for a 4630 built in 1982, this catalog has it. The aftermarket ones don’t. For more context on how these engines work, check this Wikipedia article on diesel engines.

Is This 856-Page Catalog Right for Your 4630?

If your tractor is a 4630 with a Quad-Range, Power Shift, or Syncro-Range transmission, yes. The catalog covers all three. It includes the basic tractor, engine, Roll-Gard, and Sound-Gard body serial plates. You get the full section list: 01A through 01F for the front and main assemblies, 02B through 02G for the powertrain, 03B through 03D for the rear. No missing grids. No reprints of a later edition that drops the Syncro-Range parts. This is the 1996 edition — the one that matches the last production runs.

If you work on other models, you might need the John Deere 4630 1996 Parts Catalog – Factory OEM Specs for your own rig, or the John Deere 2130 Parts Catalog – Factory Specs for Correct Part Identification for smaller frames. For the 4000 series, check the John Deere 4500, 4600, 4700 2000 Parts Catalog – OEM Grid Index.

FAQ

Does this catalog include torque specs for the head bolts?

No. This is a parts catalog. Torque values are in the service manual. But if you need the correct head gasket part number, it’s in here.

How do I look up a part without the grid number?

Use the index at the back. It lists every component alphabetically and gives the grid reference. Covers 856 pages, so be patient. It works.

Can I use this catalog for a 4630 built after 1996?

If the tractor is a 1996 model or older, yes. The publication date is 1996, but the content covers all 4630s produced up to that point. Later serial number breaks would need a newer supplement.

What’s the difference between a factory catalog and a third-party reprint?

The factory catalog comes directly from John Deere’s engineering files. Third-party reprints often scan old copies, miss updates, and sometimes substitute generic part numbers. I’ve seen reprints list a $10 O-ring as a $150 housing because the image was wrong. Pay for the factory one. It’s cheaper in the long run.

You’re tired of wasting time on wrong parts. I get it. So stop guessing. Access the Factory Manual and start ordering the right pieces the first time. Every grid, every number, every serial break — it’s all there because John Deere put it there. That’s the only way I work, and it should be the only way you work.
