Caterpillar 740B, 735B, T4R, L4E, L4D 2011 Operators Manual

I have seen guys pull an aftermarket reprint off the internet, skip the safety section, and end up with a pinched hand because the steering frame lock procedure was wrong. That does not happen with this book. This is the original 2011 Caterpillar 740B, 735B, T4R, L4E, L4D 2011 Operators Manual – 149 pages of factory-sourced instructions that match what shipped in the literature holder of every 740B and 735B articulated truck. If you run a shop in San Antonio or wrench on Cat iron anywhere in North America, you need this on the bench, not a PDF someone scanned sideways.

Serial Number Prefixes T4R, L4E, L4D – Why They Matter

Page 1 of this manual lists the exact serial number prefixes: T4R, L4E, L4D, and also T4P. That means every procedure, every torque value, and every fluid capacity in this book was written for those specific machines. I do not care if the aftermarket guy says his manual covers “all models.” When you are torquing the wheel bearing nut on a 735B with a T4E prefix, you need the Cat spec, not a guess. The manual tells you to store it in the operator’s compartment, seat back literature holder, or the literature holder – because Cat expects you to have it with the machine. Period.

Safety Section – Not Just a Liability Waiver

The safety section starts with basic precautions and lists the exact location of every warning sign and label on the machine. It even references safety.cat.com. I have seen techs skip the “Lock Out / Tag Out” procedure because they thought it did not apply to an articulated truck. Then they lost a finger. This manual does not let you skip. It tells you to read and understand the basic precautions before operating or performing lubrication, maintenance, or repair. That is not optional – it is printed in black and white on page 2. The foreword also says: “Whenever a question arises regarding your machine, or this publication, please consult your Caterpillar dealer for the latest available information.” So if something does not look right, you call the dealer. You do not guess.

Operation Section – Gauges, Switches, and Controls

This section is written for the new operator and as a refresher for the experienced hand. It covers gauges, switches, machine controls, attachment controls, transportation, and towing. Every photograph and illustration shows the correct procedure for checking, starting, operating, and stopping the machine. One thing I always tell new guys: do not rely on muscle memory. The operation section explains the basic techniques – and then says “skill and techniques develop as the operator gains knowledge of the machine and its capabilities.” That is honest. It also notes that some photos may show details or attachments different from your specific machine, because guards and covers might have been removed for illustration. So look at the text, not just the picture.

Maintenance Interval Schedule – The One Safe Source

The maintenance section is structured around the Maintenance Interval Schedule (MIS). That schedule lists items to be maintained at specific service intervals, plus a “When Required” category for things like air cleaner replacement. Each item points you to the exact page in the manual where the step-by-step instructions live. The manual calls the MIS an index or “one safe source” for all maintenance procedures. Use the service hour meter to determine intervals – but calendar intervals (daily, weekly, monthly) are acceptable if they come first. Under extreme dust or wet conditions, you adjust accordingly. If you are working on a 740B that runs in a quarry in Texas, you are not following the 500-hour oil change from a generic manual. You follow the factory schedule that accounts for severe conditions.

If you need to service the drivetrain, the Manual Transmission section in the factory manual covers shift points and lubrication specs. For other Cat powerplants, the Manual Transmission section from the OEM powertrain documents will cross-reference directly.

Source Authenticity – OEM Print vs. Third-Party Scans

I do not trust aftermarket documentation. Point blank. I have seen third-party manuals that omit the foreword, skip the safety label locations, and misprint the torque values for the brake release system. This manual is a direct print from the original 2011 Caterpillar publication SEBU8345-00. It is not a copy. It is not a reprint. It is the exact document that would have come with the truck from the factory. The PDF you access from AutoRepairManuals is a scan of that original – not a retyped version that introduces errors. That is why the page count is 149 pages, not 120 or 175. That is why the serial number blocks are correct. If you want to verify, check the safety.cat.com reference – it is still active as of 2024. Third-party sellers cannot offer that.

For comparison, check out the Caterpillar 3508, 3512, 3516 2009 Operators Manual – OEM Specs for large diesels, or the Caterpillar C18 2004 Operators Manual – Factory Specs & Safety for industrial engines. If you need hydraulic excavator coverage, the Caterpillar 330D Hydraulic Excavator Operator Manual uses the same documentation philosophy.

Frequently Asked Questions

Does this manual include wiring diagrams or electrical schematics?

No. This is an Operators Manual, not a Service Manual. It covers operation, maintenance intervals, lubrication, basic troubleshooting, and safety. For electrical diagnostics you need the separate Caterpillar Service Manual for the 740B/735B. That said, the operation section does describe gauge functions and warning lights – enough for an operator to know what a red light means before calling a tech.

Will this manual work for a 740B with serial number T4P?

Yes. Page 1 lists T4P as one of the serial number prefixes covered.

Every time I see a machine come in with a service record that used aftermarket specs, I know the next job will be fixing something that was torqued wrong. Stop that cycle. Access the Factory Manual from AutoRepairManuals and put the right numbers on the job.
