John Deere 4630 1996 Parts Catalog

You are rebuilding a John Deere 4630 and you need the correct Parts Catalog. This is the factory book – not a third-party reprint. I have used these documents for over 28 years. They are the only source for the exact OEM part numbers and applications. This one runs 856 pages and covers the 1996 model year.

I have lost count of how many times I have seen a guy pull a part off a salvage tractor and assume it fits because it looks close. On the 4630, the 404 cubic inch engine had multiple versions depending on the serial number range. Aftermarket parts sites will not tell you that. This catalog will. It gives you the serial number breakdowns for the basic tractor, engine, short block, Roll-Gard, and Sound-Gard body. Page 10-2 shows you exactly where the basic tractor serial number plate is located – rear of the transmission case. Page 10-3 does the same for the engine serial number, right-hand side behind the injection pump. If you skip those steps, you order the wrong piston ring set and waste a week.

Serial Number Location: Start Here

Every 4630 tractor has five serial number plates: basic tractor, engine, short block, Roll-Gard, and Sound-Gard body. The catalog breaks down the format for each one. For the engine, it designates the number of cylinders (6), cubic inch displacement (404), type of air intake (turbocharged and intercooled), factory user, version, serial number, and manufacturer. The short block serial number plate is attached to replacement short block assemblies with two 2-37H44 drive screws. You stamp the previous engine serial number into the blank space provided. Dealers rely on that reference. So should you.

Engine Parts Grids: Section 01 Breakdown

Section 01 of the catalog is divided into grids 01A through 01F. Each grid covers a specific subsystem of the engine. For example, 01A02 through 01A25 cover the engine block and cylinder head components. 01B01 through 01B25 cover the valve train and camshaft. 01C01 through 01C25 go into the lubrication system. 01D01 through 01D25 handle the fuel injection system. 01E01 through 01E25 cover the cooling system. 01F01 through 01F09 cover the turbocharger and intake manifolds. If you need a part for the 6-cylinder engine, you start here. Cross-reference the grid number with the illustration and parts list. Do not guess.

Transmission and Drivetrain: Section 02 Coverage

Section 02 covers the transmission and drivetrain. The grids are arranged differently: 02B08 through 02B25 for the Quad-Range transmission, 02C01 through 02C24 for the Power Shift, 02D01 through 02D24 for the Syncro-Range, 02E01 through 02E25 for the final drives, 02F01 through 02F25 for the differential and PTO, and 02G01 through 02G18 for the rear axle and brakes. You have to identify which transmission your 4630 has – the serial number prefix tells you: H for Quad-Range, P for Power Shift, W for Syncro-Range. The catalog does not make that obvious on every page, so read the front matter carefully.

Hydraulic System Parts: Section 03 and Beyond

Section 03 gets into the hydraulic system. Grids 03B08 through 03B25 cover the hydraulic pump and controls, 03C01 through 03C25 cover the hydraulic cylinders, and 03D01 through 03D19 cover the filters, lines, and cooler. The catalog does not include repair procedures – it is a parts catalog. But if you know what you need to order, this is the only reliable reference. Aftermarket catalogs often lump multiple transmission types into one generic page. This does not. Each part number is specific to the serial number range and transmission type.

Why OEM Documentation Beats Aftermarket

I have seen aftermarket parts catalogs that group the 4630 with the 4640 and call it close enough. It is not. The 4630 uses a different short block, different injection pump, and different final drive ratios. The OEM catalog from John Deere – published in 1996 – uses the original Deere & Company grid system. Each part is illustrated with a callout number and a table of part numbers, quantities, and descriptions. No abbreviations that make you guess. No vague references to “similar” models. This is the document that John Deere parts departments use. If you are rebuilding a 4630, you need it.

Understanding the diesel engine itself can be helped by this Wikipedia article on diesel engines and this Wikipedia article on diesel engines for background on the 6-cylinder 404 inline design. But for actual part numbers, stick with the factory source.

Frequently Asked Questions

Does this catalog include part numbers for the engine?

Yes. Section 01 covers the engine in grids 01A through 01F with full part numbers and illustrations.

What transmission types are covered in the catalog?

The catalog covers the Quad-Range, Power Shift, and Syncro-Range transmissions for the 4630. Each has its own grid set in Section 02. You need to know your transmission letter code from the serial number.

How do I find the right part for my 4630 if I don’t know the serial number?

You have to locate the serial number. The catalog tells you exactly where each plate is located – basic tractor at rear of transmission case, engine behind injection pump, etc. Without the serial number, you cannot narrow down the part. Do not skip this step – it is the difference between ordering the correct piston and ordering a paperweight.

Is this a service manual or a parts catalog?

This is a parts catalog only. It contains part numbers, diagrams, and quantities. It does not contain repair procedures or torque specs.

Other related manuals you may need: John Deere 4630 Tractor 1996 Parts Catalog, John Deere 2130 Parts Catalog – Factory Specs for Correct Part Identification, and John Deere 4500/4600/4700 Compact Utility Tractors Index. These are all factory-verified documents from the same source.

If you are serious about getting the right parts for your 4630, stop cross-referencing generic websites. Access the Factory Manual directly from AutoRepairManuals. It is the same 856-page PDF that John Deere dealers use. No reprint. No guesswork. Just the original OEM file with all serial number charts and grid illustrations. Get it, print the pages you need, and keep them greasy on the workbench.
