A lathe belt may at one point need to be replaced. You will not need to panic as the job of replacing this is not one that is very difficult. It is always a good idea for you to pay close attention to your lathe belt so that you will be able to properly prepare for it to be replaced. With the right amount of tools and know how you will find that the job itself is one that is pretty simple to do.

Step 1 – Prepare for Drive Belt Removal

The first thing that you will need to do is get the drive belt removed. Get your manufacturer’s guide out so that you will be able to properly get all of the lathe covers removed. Once you have done this, you will be able to get the power source taken off from your lathe. Simply unplug it or throw the breaker. If you have a newer tool then you will have a lock out option that you can also use. Get the belt completely tightened until you can see it. From there, it is time to get the two bolts that are holding the swing arm where it is. Remove them from the adjustment nut.

Step 2 – Removal of Drive Belt

There are four bolts that are going to need to be removed. They are what holds the bearing assembly to the drive shaft of the lathe. Your drive shaft is going to end up hanging only by the speed belt. This will help you to be able to easily have access to the belt and get it removed. Get a good look at the belt to see any problem areas. Look over the cogged wheels to make sure that there is no left over debris from the old belt.

Step 3 – Drive Belt

Once you have inspected the area you will then be able to get the drive belt replaced. You will begin by getting the drive assembly as well as the lower wheel moved and out of your way. Once you have done this you are ready to put in the new belt. In order to do this you will get the belt stretched into its proper location, you can do this with your fingers and any sort of blunt tool.

Step 4 – Drive Belt Replacement

It is now time to put the drive bearing assembly back where it is supposed to go. Be sure to get it bolted down into place. From there, it is time to get the speed adjustment arm reattached and bolted as well. The wheel that you use to adjust the lower pulley as well as the speed adjustment wheel will need to be reattached as well. Make sure that they are attached as close as they can get. Get the belt tightened onto the drive assembly and get the lathe covers replaced. You will simply go in the reverse order that you did when removal took place.
