How to Replace the Timing Belts on an Onfloor EZV Sander

Thursday, May 28, 2020 Travis McCutchen

If you notice that one of your sander pad is not turning or it's wobbling, then your belt may be broken. There are a couple of reason on why your belts get broken and one of them would be related to studs that we find in the floor, studs left behind from a tool, a piece of equipment that's been bolted down to the floor, or a wall that's been bolted down to the floor. It may also be that your belt has worn out from over usage. What ever it may be, we need to replace the belts and this article will walk you through the process.

Needed Tools

Rubber Mallet and Safety Knife

You will need the rubber mallet for the removal and installation process. The safety knife on the other hand is for cutting the timing belt loose.

REPOSITION THE HANDLE

Please be sure that the power cord is unplugged before servicing.

Before we start, please make sure the machine is not plugged into the power source, utilize the lockout tagout procedure and refer to the EZV manual.

To begin working, pull the pin out of the handle, reposition the handle to the upright position, reinstall the pin, and then lay the machine back and rest it on the floor.

test the timing belts

First, you should test the timing belts before you replace them using the following steps. Turn one of the sander pads by hand. When you're turning the pad, the other two should also turn in unison. If one or both of the other pads do not spin, then the belts have either become worn and have come loose, or they're broken. If this is the case, then you must replace all three belts.

If your pads are bolt-on style pads, then you'll need to remove the bolts first. You can also check on this article on how to remove a bolt-on sander pad on an OnFloor OF16S EZV Sander.

Remove the cover plate

Using the #3 Phillips-Head Screwdriver, or the H8 Allen Head if your model requires it, remove the eight screws that attach the sander plate to the machine.

Remove the cover plate by sliding the flat screwdriver between the cover plate and the inner drum and prying it off. You may also find it easier to just stand the machine up and allow the cover plate to fall off.

The machine shown in this video does not have belt plates covering the belts. If your machine does have them, then you will need to remove the three plates by taking out the nine screws that attach them before going to the next step.

Cut the old belts

Now, carefully cut all three old belts off with the safety knife and remove them.

install the new belts

To install the new belts, begin with the furthest gear in on the center pulley. Apply the belts to the center pulley first. Line up the notches on the belt with the teeth on the gears. Then wind the belt until it catches and is taut on the gear. Then repeat this with the other two belts and make sure that all three spin properly.

Reinstall the deck plates

Once all three belts have been installed, reinstall the deck plates if your machine has them. If not, just reinstall the sander plate with all of the eight screws.
