This tool helps you to do the job smoothly and perfectly, without using much effort or causing damage to your CV boot and axle. Read below for everything about the automotive CV boot clamp tool including what it is, how to use it, and what’s the best type.

Introduction to the CV Boot Clamp Tool

The CV boot clamp tool, or CV joint boot clamp tool, is a type of tool used to install CV joint boot clamps easily and safely. There are two main types of the device:

  • CV boot band clamp tool
  • CV boot clamp pliers

The CV boot band tool is used on band style clamps, which are also one of the most common (and easy-to-install) types of clamps. The tool is a combination of two different mechanisms: a clamp winder and clamp cutter.

A handle located on the side of the CV boot banding tool, as the device is also called, operates the winding mechanism to tension the clamp while a lever works the cutter.

The CV boot clamp pliers on the other hand, is a special type of pliers- or pincers- that installs ear type or crimping style clamps. There’s also a version of the tool for earless clamps and you get to choose the best type for your application.

The CV Boot Clamp Kit

The CV joint boot tool is often used as a single tool but you can also purchase in the form of a kit. The kit usually includes the different kinds of the tool: banding clamp tool and the boot band pliers. As you can guess, having a CV boot clamp kit offers the advantage of being able to service different cars.

Now that you are conversant with the two types of CV boot tools and their functions, let’s move onto how to use them. This will allow you to install various types of boot clamps, including the ear types used on front wheel drive cars.

Steps to Install a CV Boot Clamp with CV Boot Clamp Tool

Start by preparing your tool. If using a CV band clamp tool, ensure that it’s working and that the winding mechanism is lined up properly. Ensure, too, that the cutting lever is correctly positioned on the side. Check the CV boot to see that it’s properly seated on the CV joint assembly.

How to Use a CV Boot Clamp Banding Tool

Step 1: Undo the band style clamp then wrap it around the CV boot, making sure that it seats on the existing groove on the boot. Pull the free end (tail) of the clamp so it tightens around the boot.

Step 2: Insert the extended end of the clamp into the CV boot band tool. Slide it all the way through the cutter, winder, and up to the end. Pull the clamp over the end of the tool and bend it slightly.

Step 3: At this point, you want to use the CV boot clamp tool to tighten the clamp. Do so by turning the winder until the head of the tool just touches the clamp around the boot. Give the handle one last turn until there no more length of clamp or banding to tension.

Step 4: Flip the boot clamp tool over so the clamp’s end bends over the buckle-like clip or clasp. Then, turn the cutting lever to nip the excess length of the banding. This will release the tool and allow you to finish the clamp installation.

Step 5: Using a needle-nose pliers, bend the clamp’s tabs so they press against the bent part. Use the hammer to gently tap the tabs down. Your CV boot camp is now fully installed! Do the same with the clamp for the other end of the CV joint boot.

Step 1: For the ear type clamp, insert and position it around the boot. It may need adjusting based on the situation.

Step 3: Inspect the clamp to ensure the procedure worked properly and that the lamp is adequately securing the boot.
