If you're an eager DIYer who likes working on challenging repair tasks, you most certainly have tried pulling out a gear with your bare hands at least once. And what's frustrating about that attempt is that you have proven it to be futile. There are just some things beyond your strength. That is why we now have a jaw grip puller.
This tool is designed to work in a way that the tri-jaws are mounted on the gear while a threaded column pushes on to remove the gear. No doubt, this is the most effective way for anyone to pull those gears and bearings off from a very tight column. So don't act like you're some superhuman. Get yourself a jaw grip puller.
Determine the reach and spread of the part that you are going to pull. Once you've got these details, you will have a clear idea as to which size of jaw grip puller is perfect for the job. Most product descriptions include these details, so it will be easy for you to pick out what you need.
Made of steel
Because jaw grip pullers are used to resist so much pressure and are highly tensed, they are typically made of strong materials like steel. Most jaw pullers in the market are either made of alloy steel or chrome vanadium steel.
Alloy steel is a preferred material for jaw grip pullers because of its obvious durability. Jaw grip pullers made of alloy steel are strong enough to carry out the job of pulling gears and bearings, but they are not as sturdy as those made of vanadium steel.
Vanadium steel has excellent properties to boast of especially when it is heat treated. It has good resistance to wear and fatigue, and it can hold up to erosion and oxidation. It is proven to be tough despite its light weight.
Other things to consider
You would want your jaw grip puller to have a firm grip and to access tight spots easily without ever slipping. You would also want a puller that you could set up fast and without a fuss. In the first place, you decided to use that tool for things to be convenient for you. It will definitely defeat the purpose if the tool itself is not user-friendly. And lastly, you would want the nuts in your puller to be dug in real tight. You don't want any part of your tool to be disfigured once it makes an impact.
