Allison CLBT 700, CLT 700, HT 741 and HT 748 Transmission Service Manual

Allison HT, HTB, CLT and CLBT 700 series transmissions sit between the engine and the drivetrain on cranes and other heavy machines, taking engine torque and sending it to the wheels or the carrier. When one needs pulling, refitting or setting up in your own shop, you want the workshop procedure in front of you. That's what this manual is for. It's the book a technician opens when the machine is out of warranty and the job is yours.

What this manual helps you do

• Follow the removal sequence to pull the transmission from the vehicle.
• Prepare the transmission for installation before it goes back in.
• Prepare the vehicle for installation so the fit-up goes right the first time.
• Install the transmission into the vehicle, step by step.
• Verify your work with the checks and adjustments section, and keep up with preventive maintenance.

Who this is for

Independent repair shops, rental fleet mechanics and crane service technicians who handle Allison 700 series units themselves. It also suits plant maintenance staff with a used machine that arrived with no paperwork.

FAQ

Q: What do I receive and how is it organised?

A: One PDF file, 54 pages, in English. The text is searchable, so you can jump straight to a procedure. Sections run from external views of each model through preventive maintenance, removal, installation, checks and adjustments, and customer service.

Q: Which transmissions does it fit?

A: Allison CLBT 700, CLT 700, HT 741 and HT 748. The publication number is MT1958EN, titled "HT, HTB, CLT, CLBT 700 Series Mechanic's Tips." The external views also show the HTB 748, HT 755CR, HT 755DR and CLBT 755, which helps you identify what's on your bench.

Q: How does it fit the job I'm doing?

A: If you're taking a transmission out of a crane or carrier and putting it back, the manual follows that job in order. It's a complete manual for that work, and it's short enough to read before you pick up a wrench.

Pull the transmission, refit it and run the checks with the procedure open beside you.
