Caterpillar 740 2007 Parts Catalog – Factory OEM Specs

If you’ve ever ordered a part for a 740 articulated truck and got the wrong one because the aftermarket catalog had a typo, you know the headache. I’ve seen it cost a shop a full day’s labor. This Caterpillar 740 2007 Parts Catalog is the real thing – straight from the factory, 1102 pages of part numbers, illustrations, and serial number breaks. No reprints, no third-party interpretation. Just the data Caterpillar wants you to use.

1102 Pages of Factory Parts Data – What You Get

Every page in this Parts Catalog is a direct copy of the master document Caterpillar issued in August 2007. The manual covers the 740 articulated truck powered by the C15 engine. You get the complete Machine Arrangement, Engine Arrangement, Basic Engine, Lubrication System, Cooling System, Air Inlet and Exhaust System, Fuel System, Electrical and Starting System, and Power Train. Each section is broken into “groups” – for example, under Basic Engine you’ll find ACTUATOR GP- VALVE, CAMSHAFT GP, CYLINDER HEAD GP, and so on. That’s how you find the exact part number without flipping through a generic index.

Engine Arrangement and Basic Engine: Where the Valve Actuator Lives

Need a new valve actuator? Look under BASIC ENGINE → ACTUATOR GP- VALVE. The manual lists every part in that group with its Caterpillar part number, quantity, and illustration reference. Same for the transmission – the ENGINE & TRANSMISSION AR section shows the full assembly. For torque converter and output transfer gear, the serial number prefixes are on page 1: B1P1-Up (Machine), LHX1-Up (Engine), MRF1-Up (Transmission), TCY1-Up (Torque Converter), A5L1-Up (Output Transfer Gear). Verify your serial number before ordering.

Does This Manual Cover the Transmission and Power Train?

Yes. The POWER TRAIN section is massive – it includes the axle arrangements (front, center, rear), differential carriers, transmission case, brake and torque converter coolers, and the control groups for transmission hydraulics and differential lock. Page 2 in the manual shows the fields you need to fill out for your machine’s serial numbers. Fill that out first. It saves you from ordering the wrong axle bearing.

Why You Need the OEM Parts Catalog, Not a Reprint

Aftermarket parts catalogs often skip the “SUPPLEMENTAL COOLANT ADDITIVES” section or the “REPAIR ALTERNATIVES” notes. That’s where Caterpillar tells you which coolant additives are approved for the 740. I’ve seen head gasket failures from using the wrong coolant additive. The OEM catalog also includes the MAINTENANCE PARTS section with filter and belt part numbers. Don’t trust a reprint that might have lost a page. This is the original PDF.

Valve Actuator GP: Ordering the Right Part

Under BASIC ENGINE, the ACTUATOR GP- VALVE group lists the actuator assembly, mounting hardware, and seals. Each part has a unique Caterpillar part number. Cross-reference with the INDEX at the back (English, plus French, Spanish, Portuguese, German) if you’re working with a multilingual crew. The manual’s organization is logical: every system is its own chapter, then groups within. Once you get used to it, you’ll find any part for the Engine, Transmission, or Valve in under a minute.

How to Use This Manual Faster

Start with the TABLE OF CONTENTS. It’s hyperlinked in the PDF. Click “ENGINE ARRANGEMENT” to jump to that section. The machine arrangement (CHASSIS AR, GENERAL AR, INSTALLATION AR-MACHINE) is first, then the power train. If you’re rebuilding a C15, open the BASIC ENGINE section and look for CYLINDER HEAD GP, PISTON & ROD GP, or the VALVE MECHANISM COVER GP. The part numbers are listed with illustrations – no guesswork. For context on the larger automotive industry, see Automotive Industry Overview.

No, it’s a parts catalog, not a service manual. It lists part numbers and illustrations. For wiring diagrams, you need the service manual.

How do I find a part number for the valve actuator?

Look in the ‘BASIC ENGINE’ section under ‘ACTUATOR GP- VALVE’. The manual groups parts by system, then by group. Each group has an illustration and a list of parts with part numbers. Use the index at the back to cross-reference.

Can I use this for a 2008 model?

This manual covers 2007 740 articulated trucks with specific serial number ranges. Check the serial number prefix on page 1 to confirm fit. The 2008 model may have different part numbers.
