Caterpillar C4.4 2007 Parts Catalog – Factory OEM Specs

You know the feeling. You’re ordering parts for a C4.4 and you pull up some third-party parts diagram that looks correct but the part number is off by one digit. Next thing you know, the camshaft doesn’t fit the bore, or the valve guide is the wrong length. That’s billable time burned and a customer waiting. This 2007 Caterpillar C4.4 2007 Parts Catalog is the only reference you should trust on the bench. It’s the exact same PDF the dealer uses. 803 pages of factory-verified part numbers, exploded views, and group listings for the Industrial Engine. No aftermarket reinterpretation.

Engine Arrangement and Basic Engine Coverage

The manual opens with the ENGINE ARRANGEMENT section – ENGINE AR and ENGINE AR-PRIMARY. That gives you the top-level assembly layout. Then it dives into BASIC ENGINE. Under that you’ll find ADAPTER GP-AUXILIARY DRIVE, BALANCER GP, BELT TENSIONER GP, CAMSHAFT GP, CRANKSHAFT GP, CYLINDER BLOCK GP, CYLINDER HEAD AS, CYLINDER HEAD GP, PISTON & ROD GP, ROCKER ARM GP, and VALVE MECHANISM GP. Every group has its own page with a diagram and a table of part numbers, quantities, and descriptions. Need to identify a balancer for an engine serial number 4441-Up? The Camshaft group will show you the exact gear and bearing part numbers.

What Does the Parts Catalog Actually List?

This isn’t a repair manual – it’s a parts identification bible. Each section covers specific systems: LUBRICATION SYSTEM (Breather GP, Pump GP-Engine Oil, Filler GP), COOLING SYSTEM (Water Pump GP, Radiator GP, Fan GP), AIR INLET AND EXHAUST SYSTEM (Turbocharger GP, Inlet Manifold GP, Pipe GP-Exhaust), FUEL SYSTEM (Injector GP-Fuel, Fuel Injection Pump GP, Lines GP-Fuel). If you’re rebuilding a cylinder head, you’ll turn to CYLINDER HEAD AS or CYLINDER HEAD GP for the valve stem seals, retainers, and springs. The exploded diagrams show every fastener – no guessing what bolt goes where.

Camshaft GP, Crankshaft GP, Cylinder Head GP – Why Factory Specs Matter

I’ve seen guys order a camshaft from a cross-reference list only to find the journal diameters are wrong for their block. The factory catalog lists the part number specific to the C4.4 Industrial Engine with the correct grind and timing gear. Same for the Crankshaft GP – you get the exact front pulley, rear seal adapter, and keyway dimensions. The Cylinder Head group includes the valve guide and seat part numbers. If you’re swapping a head, you’ll need those numbers to order new valves and keep the compression ratio correct.

3 Reasons to Trust OEM Documentation Over Aftermarket

First, aftermarket catalogs often merge revisions. This manual is dated December 2007 (SEBP4124-07) and covers engines with serial number prefix 4441-Up. Second, the graphical quality – the exploded views are high-resolution scans, not fuzzy copies. Third, the PART NUMBER INDEX at the back lets you search by part number across all chapters. No flipping through 10 sections. You go straight from the index to the page. That saves time when you’re standing at the parts counter with a customer breathing down your neck.

Get the Right Torque Data from the PART NUMBER INDEX

The index itself is multilingual – INDEX, INDICE, ÍNDICE, STICHWORTVERZEICHNIS. But more importantly, each part listing includes the torque specification reference if applicable (though the actual torque values are in the Service Manual, not this catalog). What the index does give you is immediate cross-reference between a part number and its group location. Need the glow plug for the electrical system? Look up the part number in the index, find the page for GLOW PLUG GP under ELECTRICAL AND STARTING SYSTEM, and order the right one. You avoid the headache of a mis-shipped part.

FAQ

Does this catalog include torque specifications for the cylinder head bolts?

No. This is a Parts Catalog. Torque values are in the Service Manual. Use the separate Caterpillar C4.2/C6.4/C4.4/C6.6 ACERT Engines Service manual for assembly specs.

How do I find the part number for the valve mechanism cover gasket?

Go to the BASIC ENGINE section, look for COVER GP-VALVE MECHANISM. The diagram shows the gasket part number and quantity. If the engine serial number falls within 4441-Up, the part number listed is correct. Verify the serial number on the engine data plate – the manual includes a Product Information page where you can note the engine serial number for reference. If your engine has a different prefix, check the “General Information” section for supersession notes. The 803-page format means every revision up to 2007 is captured, so older part numbers are noted as “R” (replaced by) where applicable. This is the factory document, not a reprint – the page numbers match the original Caterpillar SEBP4124-07 book.
