Hi There,

Here's a step by step guide that will explain in detail how to remove the top cover on your Hoover. The repair was written for a different problem then one you're experiencing, but you can follow along step by step to see how you can remove the top cover.

If you haven't already purchased the actuator arm, here's a link for you to the part on Amazon

Here's the repair guide:
Step 1. Make sure that the vacuum is unplugged. Turn the machine upside down so that the brushes are facing upwards. I find the easiest way to do this is to put the brushes on top of a counter top or work bench with the handle of the vacuum resting on the floor. Remove the four screws that hold the bottom plate in place. Remove the bottom plate, both belts and then the roller brush from the machine:



Step 2. There are 3 screws that hold the top brush cover in place that need to be removed. On the right side the screw is down below the transmission to the right. There's also a screw in the agitator tray, in the middle that needs to be removed. NOTE: This small screw in the agitator tray is only present on some models, you's may or may not have this little screw, but all models will have all other screws circled. I have circled both screws that need to be removed:


The screws on the left side that need to be removed are also circled. One screw holds the upper brush cover on, and the other two screws secure the hose in place. Remove all three screwI have a Hoover Model #U6430-900, Self-propelled - e00d104.jpgs the transparent hose cover:



Step 3. After all of these screws have been removed, there are two clips that are the last things holding the top brush cover onto the vacuum. Use a flat head screwdriver to push these clipI have a Hoover Model #U6430-900, Self-propelled - 2_bing.gifoth the left and right sides. The right side clip is near the pulley that the flat I have a Hoover Model #U6430-900, Self-propelled - b39ff0c.jpgc="/uploads/images/2_bing.gif" alt="2_bing.gif" /> rides on, and the left side clip is next to the internal hose.



Step 4. Once both of these clips have been pushed so the unhook from the lower agitator housing, remove the top cover.

Once you have removed the top cover, here's a link to a guide that will show you how to replace the actuator arm itself:
