Caterpillar 320D L, 320D 2010 Parts Catalog

Nothing burns my time like a part that doesn’t fit because someone pulled a cross-reference from a third-party list. You order a hydraulic line for a 320D L, get it on the truck, and the flange bolt pattern is off by a quarter inch. That’s a half-day lost, a machine down, and a client looking at his watch. This Caterpillar 320D L, 320D 2010 Parts Catalog is the only source I trust for pulling the exact factory part number the first time. 603 pages of OEM exploded diagrams and index lines – not a reprint, not a scan of a scan. This is the actual SEBP4874-11 document Caterpillar released in August 2010, covering machine serial numbers FAL1-Up and KCF1-Up with the C6.4 engine.

Engine Arrangement Coverage: From Cylinder Head to Oil Pan

Open to the ENGINE ARRANGEMENT section starting on page 50, and you’ll find every group Caterpillar engineered into this machine. The BASIC ENGINE subsection (page 79) breaks down the CAMSHAFT GP, CRANKSHAFT GP, CYLINDER BLOCK GP, and CYLINDER HEAD GP – all with original part callouts. Need the PISTON & ROD GP? Page 104. The LUBRICATION SYSTEM chapter covers the ADAPTER GP-REMOTE OIL FILTER and LINES GP-TURBOCHARGER OIL separately. That level of granularity is what keeps you from ordering a generic “engine oil line kit” that doesn’t match your machine’s configuration.

7 Major Machine Systems With OEM Part Identification

MACHINE ARRANGEMENT runs from page 1 through 49, covering every option group: CHASSIS AR, DISTRIBUTION AR, OPTION AR-HYDRAULIC, OPTION AR-COUPLER, OPTION AR-ELECTRICAL, OPTION AR-LIGHTING, and SPECIAL AR. Each one lists the component group (GP) with its own part number. For example, the OPTION AR-CONTROL group inside the hydraulic section is a separate subsection – that’s where you find the pilot valve and joystick numbers. I’ve used this catalog to match a regional option (OPTION AR-REGIONAL page 42) on a 320D brought in from a different dealer network. Without it, I’d have been guessing at the pilot line routing.

Who Needs This Parts Catalog?

If you own a 320D or 320D L excavator and do your own maintenance, you need this. Home garage enthusiasts who take on heavy equipment repairs? Same. You’re ordering a water pump, a cylinder head gasket set, or a fan pulley – you want the factory number so you don’t get a reman part that’s been superseded twice. The GENERAL INFORMATION section (page A6) explains how Caterpillar identifies parts and where to find the product identification number. That alone saves you from calling the dealer and reading them the serial number wrong.

For professional mechanics, this catalog is billable-hours insurance. You aren’t wasting shop time chasing a part that doesn’t exist. You flip to the INDEX (page A17), find the component, and get the reference page. That’s it.

Supplemental Coolant Additives and Maintenance Parts – Factory Specs

The front matter includes SUPPLEMENTAL COOLANT ADDITIVES (page A10) and MAINTENANCE PARTS (page A11). That section lists the exact Caterpillar part numbers for coolant conditioner, fuel filters, oil filters, and other routine replacement items. Don’t trust a parts store cross-reference for coolant additives – the wrong SCA concentration can eat your liner seals. The REPAIR ALTERNATIVES chapter on page A9 tells you when a part can be serviced versus replaced. This is straight from Caterpillar’s engineers, not some aftermarket editor.

Frequently Asked Questions

Does this manual cover the 320D L and the standard 320D?

Yes. The catalog covers both models under one part number SEBP4874-11. Machine serial numbers FAL1-Up (320D) and KCF1-Up (320D L).

Are torque specs included in a parts catalog?

It’s a parts catalog, not a repair manual. Torque values are in the service manual. This catalog gives you part numbers and exploded views only. For installation torque, get the factory service manual.

Can I use this to identify parts for a 2011 or 2012 model year?

This catalog was published August 2010, so it covers the 2010 model year and earlier builds. Later machines may have updated part numbers or supersessions. You’ll want the latest revision from Caterpillar for newer machines. That said, many 2011 machines share the same C6.4 engine and major chassis groups, so it’s a strong starting point if you check the serial number range. The best practice is to cross-check the part number with your local dealer’s system if the machine is outside the listed serial range. I’ve done that plenty of times – it still saves me from ordering a completely wrong hydraulic pump because the pilot line banjo bolts differ between Option AR-Control groups. The catalog’s exploded diagrams let you see exactly which banjo bolt your group uses, so you can confirm the thread pitch and seat style before you order. That kind of visual confirmation is something an aftermarket parts website can’t give you.

Is this a PDF or a printed manual?

It’s a digital file – the original OEM PDF. You can print pages as needed. No binding to break, no oil-stained pages you can’t read.
