Perkins 5C, 6, 702, 704 Parts Catalog

If you are working on a Perkins 5C, 6, 702, or 704 and you’re guessing part numbers from a third-party website, you are wasting time and risking ordering the wrong piece. I see it every week — a tech orders a cylinder liner based on a photo, gets it in hand, and it’s the wrong height. Then the machine sits. This 151-page factory Perkins 5C, 6, 702, 704 Parts Catalog gives you the exact OEM part numbers, supersessions, and change levels so you order once. That’s the difference between a two-hour job and a two-day headache.

What This Parts Catalog Covers

Perkins built these engines across multiple production changes. The catalog breaks down every major assembly for the 5C, 6, 702, and 704. You get the cylinder block group (section 11-2), the crankshaft and timing gear, flywheel housing, auxiliary drive, and engine mountings. The table on page 2 tells you which build code — E or F — applies to your engine serial number range. For example, a 5C with engine build E uses a different cylinder block than the F variant. That information is printed right there, not buried in a forum thread.

Page 1: The Structure You Need

The opening page of the catalog shows you exactly how the manual is organized. Eight main sections: Cylinder block, Crankshaft, Timing gear, Flywheel housing, Auxiliary drive, Engine mountings, plus language-specific headings for French, German, Danish, Swedish, Spanish, Portuguese, and Italian. If you’re working on a rebuild and need piston liner part numbers, you go to the Cylinder Block section. The exploded diagrams (like the one on page 3) show each fastener, gasket, and plug with the corresponding part number listed below. That’s the kind of clarity that keeps your bench clean and your parts bin accurate.

Build Codes and Change Numbers

Perkins changed parts across production runs. The catalog lists change numbers for each model. For the 5C, change number E4707389 separates the earlier from the later builds. The 702 uses change M2966. The table on page 2 tells you which sections apply to which build. If you have a 704 with build code F, you order the cylinder block part number from the F column — 90063, not 90062X. Getting that wrong means the oil pump pipework won’t line up. The catalog even notes superseded numbers: 83983 was replaced by 84683, then by 90062X. You don’t have to cross-reference three different sources. It’s all here.

Why OEM Parts Catalog Beats Aftermarket

Aftermarket parts listings often skip the supersession history. You order what you think fits, but the original part has been updated twice. Then you get a box with a stud that doesn’t match your block because the thread pitch changed. This catalog is a direct Perkins factory print — not a photocopy of a photocopy. The part numbers are straight from the original engineering releases. For example, the cylinder block on page 4 lists item 1 with multiple part numbers: 83983, 84683, 90062X, 90063. The note says “Use 92933 with new bolt pump and pipework.” That kind of detail comes from the OEM, not from a third-party reprint. If you want to understand why your engine has a different breather pipe, this Wikipedia article on diesel engines explains the design evolution, but for the exact part number you need the factory source.

Using the Catalog on the Bench

This is a parts catalog, not a service manual. It won’t tell you how to torque the head bolts. But if you are rebuilding a 5C and need the correct main bearing cap bolt — item 17 on page 4, part number 32114116 — you see it in the diagram with the washer and tabwasher. You order those numbers. The catalog also lists plug sizes and gasket part numbers. That saves a trip to the dealership when the bolt supplier sends the wrong pitch. Count the pages: 151 pages of organized, cross-referenced data. That’s three times the thickness of most aftermarket catalogs, and every page is specific to these four engine models.

Who Needs This Manual

If you own a forklift, generator, or agricultural machine with a Perkins 5C, 6, 702, or 704, you need this catalog to order replacement parts. DIY mechanics working in a home garage will use it to match old parts to new numbers before placing an order. Professional techs in diesel shops will keep it on the bench to verify supersessions. The build codes are critical — if you have an early 702 (engine build F) and order parts for a later E build, the cylinder liner won’t seat. The catalog makes those differences obvious.

Does this catalog cover engines built after 1990?

No. It covers 5C, 6, 702, 704 engines up to the change numbers listed.

How do I use the change numbers and build codes to find the right part?

First, locate your engine serial number and find the change number in the table on page 2. For a 5C, change E4707389 means “early” (E) build. Then cross-check the part number columns — “Build E” or “Build F” — in each section. For cylinder block, the F build uses 90063; the E build uses 90062X. If a part shows “Superseded”, order the latest listed part number. The diagram pages also list quantities; don’t order 4 liners when the block takes 6. Double-check the “Qty. off” column. For example, the 5C uses 4 cylinder liners (item 4 on page 4) while the 702 uses 6. That kind of data matters when you’re at the parts counter.

Access the Factory Manual directly from this page. You get a digital PDF that you can print or view on a tablet next to your engine stand. No shipping delays, no missing pages. The file is scanned from an original Perkins document, so every part number and diagram is legible.
