Caterpillar 815F 2002 Parts Catalog – Factory OEM, 600 Pages

You’ve got a 815F soil compactor with a busted hydraulic line, and the aftermarket parts book you bought off some website gave you a part number that doesn’t cross. Now you’re staring at a machine that’s down and a parts counter guy who can’t help because your serial number doesn’t match the generic lookup. I’ve seen it a hundred times. That’s why I only spec OEM parts catalogs in my shop. The Caterpillar 815F 2002 Parts Catalog is a factory-printed, 600-page reference that lists every fastener, seal, and assembly with the correct part numbers tied to your machine’s exact serial range. No guesswork, no “close enough” numbers. You get the same information Caterpillar dealerships used in 2002.

Caterpillar 815F 2002 Parts Catalog: What’s Inside 600 Pages

This manual covers four distinct serial groups: BKL1-Up (machine), 3PD1-Up (engine), CGT1-Up (transmission), and 6YT1-Up (torque converter). Each group has its own illustrated parts breakdown. The engine section is built around the 3176C power plant. You’ll find exploded views of the cylinder head group, fuel system, and cooling system. Every part is labeled with a reference number and the Caterpillar OEM part number. The transmission and torque converter sections are separate because they share no common parts with the engine or chassis – and don’t let anyone tell you otherwise. I’ve seen guys order a transmission input shaft using a machine serial number and wonder why it didn’t fit. The manual makes it clear which group you need to look in.

Machine Serial Number Ranges: BKL1-Up and Beyond

Page 1 of the catalog shows the machine prefix BKL1-Up. That tells you this manual applies to 815F compactors built from the first machine with that prefix onward. If your compactor has a plate that starts with BKL, you’re covered. The engine prefix 3PD1-Up, transmission CGT1-Up, and torque converter 6YT1-Up are listed right under the model name. Don’t rely on the engine serial alone – the machine’s PIN must match the model designation. I’ve seen a 3176C engine swapped into a different chassis; the parts catalog won’t help you if the machine serial is off. Check the Identification Plate location (section of the O&M manual) before you order anything.

Engine Serial Numbers and the 3176C

The 3176C engine is a six-cylinder direct-injection diesel. This parts catalog groups the engine components by function: cylinder block, cylinder head, fuel system, lubrication, cooling. Each group starts with an overview page showing the assembly, then individual exploded views. If you need a piston kit, you look under the cylinder block group, find the piston and connecting rod assembly, and read the part number. No flipping through vague generic diagrams. The catalog uses OEM part numbers only – not aftermarket cross-references. That means when you call the dealer, you give them the exact number from this book and they order it. No delays.

Transmission and Torque Converter: Separate Groups

The transmission group (CGT1-Up) covers all internal and external transmission parts: clutches, bearings, shafts, and the housing. The torque converter group (6YT1-Up) is a separate section. Why? Because the torque converter is a standalone unit with its own serial range. If you try to order a torque converter seal from the transmission group, you’ll get the wrong part. The manual lays out both groups with clear labels. For example, the torque converter stator shaft is listed only in the 6YT group. Save yourself the headache and always check the serial prefix for the component you’re working on.

Get the Part Number Right the First Time

Here’s the workflow I teach every new tech: 1) Locate the machine PIN (product identification number). 2) Write down the engine, transmission, and torque converter serial numbers from their respective plates. 3) Open the manual to the group that matches the serial prefix. 4) Find the illustrated view of the assembly you’re repairing. 5) Read the part number from the table next to the reference number. Do not skip step 2. I can’t count how many times a guy ordered a part using the machine serial alone and got the wrong transmission seal because the transmission had been swapped. This manual forces you to verify each component’s serial range. That’s the difference between a shop that keeps machines running and one that keeps parts on order.

Product Identification Plate Locations

The manual includes pages for recording your machine’s information: model, PIN, engine serial, transmission serial, torque converter serial, and attachment serials. These are the same forms Caterpillar used for dealer records. Fill them out and keep a copy in the machine. On page 2, you’ll find a note referencing the Operation and Maintenance Manual for exact plate locations. If you don’t know where the plate is, don’t guess – look it up. The plate on the 815F is typically on the right side of the frame near the operator station. The engine plate is on the valve cover. Write down every number before you open the parts catalog.

Why Factory Parts Catalogs Beat Aftermarket Knockoffs

Aftermarket parts catalogs often reprint generic diagrams with part numbers that have been superseded or are completely wrong. I’ve had a customer bring in a part number from a third-party manual that turned out to be for a different model year. The 2002 Caterpillar 815F Parts Catalog is scanned from the original dealer document – not a copy of a copy. The part numbers are the same ones Caterpillar used in 2002. If a part has been superseded, the catalog shows the original number so you can trace it through Caterpillar’s system. This manual is 600 pages of verified data. That’s real factory density.

Frequently Asked Questions

Does this parts catalog include repair procedures?

No. This is a parts catalog for ordering correct replacement parts. You need the separate service manual for removal and installation steps.

How do I find the correct part number for my 815F?

Start by locating all four serial numbers: machine PIN, engine, transmission, torque converter. Match each to the prefix in this manual (BKL1-Up, 3PD1-Up, etc.). Then find the assembly group in the catalog that matches the serial prefix. For example, if your engine serial starts with 3PD, look in the engine group. The exploded diagram will show the part with a reference number. The table next to it lists the OEM part number and quantity. Write down the number exactly as shown. Do not add hyphens or spaces – Caterpillar part numbers are alphanumeric with no separators. Double-check before ordering. This manual contains the same data the dealer uses.

Can I use this manual for a Caterpillar 816F or 814F?

No. This manual is specific to the 815F Soil Compactor with the serial ranges listed on page 1. The 816F has a different chassis and engine configuration. Using this catalog for a different model will give you incorrect part numbers. Order the correct manual for your machine.

Is the entire manual in English?

The technical content (parts lists and illustrations) is mostly English, but the first few pages include French, Spanish, and Portuguese translations for the product information and dealer contact sheets. The part numbers and diagram callouts remain in English throughout.
