Caterpillar 3512B 2007 Parts Catalog – Factory OEM PDF

If you have ever ordered a gasket, injector, or piston ring for a Caterpillar 3512B 2007 Parts Catalog and got the wrong part because some aftermarket site listed a universal number, you know exactly why I am writing this. This is the factory PDF – SEBP3916-31, May 2007 – not a scanned copy of a copy. 152 pages of genuine Caterpillar part numbers, exploded-view diagrams, and ordering codes. No third-party shortcuts. No guesswork.

152 Pages of Factory Part Number Data

This PDF was published by Caterpillar in 2007 for the 3512B Marine Engine. The file is a direct digital copy of the printed manual – not a reprint, not a condensed version. It includes the full Product and Dealer Information section, part number tables for every subsystem, and the official Caterpillar SIS update notes. You get the same document dealers use when they look up a part on their terminal.

Where to Find Your Engine Serial Number

Page 3 of the catalog shows the Product Information page where you record the engine serial number, transmission serial number, and generator serial number. If you do not know your S2L1-Up prefix, you will order the wrong part. The manual tells you exactly where to locate the identification plate. Caterpillar 3512B Engine 2007 Operators Manual covers that plate location in more detail, but this parts catalog gives you the serial number ranges used for part allocation.

How This Catalog is Organized

Each major engine group has its own section – cylinder block, cylinder head, fuel system, lubrication, cooling, air intake, exhaust, and electrical. Every section opens with an exploded line drawing showing how the parts fit together. Below each drawing is a table with the part number, description, and quantity per assembly. You do not have to guess whether a 1N-1234 fits your build. The catalog lists it with the correct serial number range.

Understanding the ‘General Information’ Section

The manual opens with a note about “General Information” for new parts manual features. That page tells you what changed in this 2007 edition compared to earlier prints. It also explains how to interpret the SIS designation and the compact disc availability. If you skip that page, you might miss a superseded part number or a discontinued item. Read page 1 before you place your first order.

Aftermarket vs OEM: Why This Catalog Saves You Time

An aftermarket parts list might say “replaces OE number 123-4567” but they do not always cross-reference the exact casting revision or the torque-to-yield spec that came with the original part. This catalog gives you the Caterpillar part number as it shipped from the factory. When you order that part number from any Caterpillar dealer, it matches. No returns because the aftermarket catalog said “fits 3512B” but the bolt holes were off by 2 millimeters. I have seen it happen. You need the OEM document. Caterpillar 3512B, 3524B Technical Manual – 106-Page OEM Factory Specs gives you the torque values and clearances – but this parts catalog gives you the numbers to order. Stick with factory data. Automotive Industry Overview shows how global supply chains rely on standard part numbering systems – Caterpillar’s is one of the most precise in the industry. Automotive Industry Overview reinforces that with tens of thousands of parts, the OEM catalog is the only reliable source.

One more thing – do not trust a third-party site that claims they have the same catalog. They often miss pages, use low-resolution scans, or omit the serial number cross-references. This access is the original 152-page PDF, searchable, printable, and watermarked only with the AutoRepairManuals branding. You keep it on your tablet or computer. No shipping delays.

Does this parts catalog include engine overhaul procedures?

No. This is strictly a parts catalog for ordering replacement components. Go to Caterpillar C15 2006 Parts Catalog – Factory OEM 884 Pages for a different engine, or use the technical manual for disassembly steps.

How do I know which part number applies to my engine serial number?

Every part table in this catalog is organized by serial number prefix (S2L1-Up). You look up your engine serial number on the identification plate, then find the corresponding column in the parts table. If your engine falls outside the prefix range shown, the part may not be correct. I have seen guys order a cylinder head gasket for an earlier build and blow a coolant seal. Check the serial number range before buying anything.

The only way to keep a Caterpillar 3512B running with the right parts is to use the factory catalog. Access the Factory Manual now and stop relying on aftermarket guesses.
