If you’re a mechanic, you know how important it is to have the right tools for the job. One tool that should be in every mechanic’s toolbox is a crankshaft bolt removal tool. This tool is essential for removing and installing the crankshaft bolt on any engine. In this article, we’ll discuss everything you need to know about crankshaft bolt removal tools.
What Is a Crankshaft Bolt Removal Tool?
A crankshaft bolt removal tool is a special tool designed to remove the crankshaft bolt from an engine. The bolt holds the harmonic balancer or pulley onto the crankshaft. It can be difficult to remove without the proper tool.
Why Do You Need a Crankshaft Bolt Removal Tool?
Without a crankshaft bolt removal tool, trying to remove the bolt can be difficult, if not impossible. The bolt is typically torqued on at over 100 ft-lbs of force, which makes it extremely challenging to remove without the right equipment. Using other tools, such as pliers or a wrench, can damage the bolt or even break it off completely.
How Does a Crankshaft Bolt Removal Tool Work?
A crankshaft bolt removal tool works by applying force to the bolt while keeping the harmonic balancer or pulley stationary. The tool typically consists of a set of bolts with a center rod that screws into the center of the crankshaft. Once in place, the bolts are tightened against the harmonic balancer or pulley, holding it in place while pressure is applied to loosen the crankshaft bolt.
Types of Crankshaft Bolt Removal Tools
There are several different types of crankshaft bolt removal tools available on the market today. Some are specific to certain makes and models of vehicles, while others are more universal.
Socket Type
The socket type of crankshaft bolt removal tool is one of the most common types on the market. It features a socket that fits over the bolt head and a center rod that screws into the crankshaft. The socket is typically held in place with a set of bolts that tighten against the harmonic balancer or pulley.
Impact Type
An impact type of crankshaft bolt removal tool uses an air impact wrench to apply force to loosen the bolt. This type of tool is typically faster than other methods but can be more expensive.
Hydraulic Type
A hydraulic type of crankshaft bolt removal tool uses hydraulic pressure to apply force to loosen the bolt. This type of tool is typically more expensive than others but can be useful for heavy-duty applications.
Electric Type
An electric type of crankshaft bolt removal tool uses an electric motor to apply force to loosen the bolt. This type of tool is typically less powerful than other types but can be more convenient for smaller jobs.
How to Use a Crankshaft Bolt Removal Tool
Using a crankshaft bolt removal tool is relatively straightforward, although there are some steps you should follow to ensure you use it correctly.
Step 1: Remove the Accessory Belt
Before attempting to remove the crankshaft bolt, you’ll need to remove any accessory belts that might be in the way. This will give you better access to the crankshaft bolt.
Step 2: Secure the Harmonic Balancer or Pulley
Once you have access to the crankshaft bolt, you’ll need to secure the harmonic balancer or pulley using your chosen method. Make sure it’s held securely in place so it doesn’t move when you start applying pressure to the crankshaft bolt.
Step 3: Apply Pressure
Using your chosen method, apply pressure to loosen the crankshaft bolt. Be careful not to apply too much pressure, as this can damage the engine or break the bolt off completely.
Step 4: Remove the Bolt
Once you’ve loosened the crankshaft bolt, you can remove it using a standard socket wrench or breaker bar. Be sure to keep track of any washers or spacers that might be on the bolt so you can replace them correctly.
Conclusion
A crankshaft bolt removal tool is an essential piece of equipment for any mechanic. Without one, removing and installing the crankshaft bolt can be difficult, if not impossible. With several different types available on the market today, there’s sure to be one that fits your needs and budget.
