Caterpillar 236, 246, 252, 262 2011 Parts Catalog | OEM 686 Pages

Description

Ordering the wrong part for a 236 or 262 is a fast way to burn money and stall a job. I’ve seen guys pull a cylinder head, then find out the gasket set they ordered doesn’t match the serial number break. That’s a two-hour drive to the dealer and a whole afternoon wasted. This Caterpillar 236, 246, 252, 262 2011 Parts Catalog puts the factory part numbers in your hands before you pull a single bolt. 686 pages, direct from the OEM, no aftermarket guesses.

Caterpillar 236, 246, 252, 262 Parts Catalog: The Foundation of Any Repair

Every engine and machine group is laid out with exploded diagrams and corresponding part numbers. Need the piston and rod assembly for a 252? Page 56 shows the PISTON & ROD GP with every ring, pin, and clip listed. The serial number ranges are right there on page 1: 4YZ4000-Up for the 236, 5SZ4000-Up for the 246, CED1-Up for the 252, FDG1-Up for the 262. Match your machine’s PIN to the correct section before you order anything.

Engine Arrangement: Finding Your Engine Group

The ENGINE ARRANGEMENT starts on page 7. You get ENGINE AR-PRIMARY and INSTALLATION AR-ENGINE. Below that, BASIC ENGINE splits into 22 subgroups—CAMSHAFT GP (page 16), CRANKSHAFT GP (page 22), CYLINDER BLOCK GP (page 24), CYLINDER HEAD GP (page 29), and so on. Each group has its own parts list. The diagram shows fastener locations and quantities. If you need the oil pan gasket for a 3034 engine, go to PAN GP-OIL on page 48. That page lists the pan, the drain plug, and every bolt with thread size and length. No guessing.

7 Systems Covered: From Cooling to Fuel

Beyond the engine block, this catalog covers all major systems. The COOLING SYSTEM (page 66) includes RADIATOR & HYD OIL COOLER GP, WATER PUMP GP, and CONNECTION GP-WATER. The AIR INLET AND EXHAUST SYSTEM (page 109) gives you AIR CLEANER GP, TURBOCHARGER GP (page 137), and MUFFLER GP. The FUEL SYSTEM (page 146) covers FILTER GP-FUEL, GOVERNOR GP, and FITTING GP-FUEL LINES. Each section has its own parts breakdown. You can trace a fuel line from the tank to the injector without lifting a wrench.

OEM vs Aftermarket: Why Factory Diagrams Matter

Aftermarket parts catalogs often merge multiple years into one drawing. A 2009 bracket might look the same as a 2011, but the bolt pattern shifted. Caterpillar updates part numbers with engineering changes. This 2011 catalog captures those changes exactly. The SUPPLEMENTAL COOLANT ADDITIVES section on page A8 tells you which coolant conditioner part number fits your machine. The MAINTENANCE PARTS section on page A9 gives you the right filter and belt numbers. That’s information you won’t find in a third-party reprint. I’ve been burned by generic catalogs; I only trust the Caterpillar factory document.

Does This Manual Include the Supplemental Coolant Additives Section?

Yes. Page A8 lists SCA part numbers and concentration requirements. If you’re servicing a 246 that runs in high-heat conditions, you need that data. The same section tells you how to maintain freeze protection without over-dosing. Skip it and you risk cavitation damage.

FAQ

Is this a repair manual or a parts catalog?

It’s a factory parts catalog. Use it to identify part numbers, not repair procedures.

How do I find the correct part number for my engine?

Flip to the Engine Arrangement section starting on page 7. Find your engine serial number range—4YZ4000-Up, 5SZ4000-Up, etc. Then go to Basic Engine, page 16, and locate the specific group like Cylinder Head GP on page 29. Each component is shown in an exploded diagram with a callout number. Cross-reference that callout with the parts list beside it. That gives you the OEM part number. Do not guess based on visual matching alone—Caterpillar updated parts over production years and the 2011 catalog captures those changes. If you order by eye, you might get the wrong piston or gasket. Use the manual.

After you get the catalog open, take the time to read the GENERAL INFORMATION section on page A4. It explains how to decode part number changes and supersessions. The REPAIR ALTERNATIVES page A7 shows you when to rebuild versus replace. That kind of data saves hours of wasted research. For the Automotive Industry Overview context, remember that factory parts documentation is the backbone of safe, reliable repairs. Nobody in my shop touches a machine without the correct parts catalog open.
