How to Change Actuator on Hoover Self-Propel vacuum Cleaner - Step by Step\015\012\015\012 \015\012This is a notorious problem for the Hoover WindTunnel Self-Propelled Models. What happpens is that the handle of the vacuum that controls the transmission is controlled by an actuator arm that is attached to a cable that runs down through the machine. The poor design of this self propelled system is design in such a way that if you pick up the vacuum using the handle (this is natural way to do it, I'm guilty of this as well), it puts too much strain on the actuator arm that controls the self-propelled mechanism, and causes the nut, washer, and screw to strip right out of the actuator arm. This explains why your handle is so loose. You may verify this by looking at the gap between the upright body, and the lower agitator housing, right where the vacuum pivots when you step on the handle release pedal. You should see when you move the handle up and down that the cable and nut are the only parts moving, and you should be able to see where the nut did sit inside of the actuator arm before it was stripped. The good news is that this is a relatively inexpensive part, and the repair is really not that difficult.
\015\012I will explain step by step, and include pictures so that you may see how to replace the part that's broken.
\015\012Always be sure your vacuum is unplugged from the electrical outlet before performing any kind of service!
\015\012Tools and materials:
\015\012Torx bit or driver size T-25
Flat blade screwdriver
Phillips screwdriver
Actuator arm – Hoover part number 43143046
\015\012Here's the picture of the part that probably needs to be replaced.
\015\012Step 1. Place your vacuum cleaner upside down with handle resting on the floor and brush roll housing resting on a work bench.
Remove 4 screws from rug plate and set rug plate aside.
\015\012Step 2.
\015\012Remove power drive belt, brush roll belt and brush roll.
\015\012Step 4.
\015\012Remove 6 screws as shown. Also remove duct hose cover and small plastic section that was under brush roll in upper left corner.
\015\012Step 5.
\015\012Place vacuum right side up on top of work bench with handle all the way back. Using a flat blade screwdriver; gently pry the top cover away from the bottom housing in the area shown by(#1) arrows. Leave the 2 adjustment knobs(#2) in place.
\015\012Step 6. If the self-propel adjustment cable HAS NOT broken away from the actuator arm, proceed as follows; mark the position of the cable(#1) in relation to the cable retainer with a black magic marker to avoid having to readjust the cable position. Remove the screw(#2) (usually a Torx T-25 size screw) and cable retainer. Next, using a flat blade screwdriver; slide the ‘C’ ring (#3) off the metal post. Bend the metal bracket up off the post just enough so you can lift the damaged actuator up and off the post. Slide your new actuator arm back over the metal post. Slide the ‘C’ ring back over the post.Lock the self- propel cable back in place with screw and retainer. Test to ensure the power drive is adjusted correctly; CAUTION, YOU ARE ABOUT TO COME VERY CLOSE TO MOVING MACHINERY, NO NECKTIES, NECKLACES, LOOSE SHIRT TAILS,UNACCOUNTED FOR TOOLS OR CLUMSY FINGERS ARE ALLOWED FOR THIS NEXT STEP!!! Reinstall the power drive belt, plug your vacuum cleaner back in and turn it on. Check to make sure the handle is in the neutral position; observe that the power drive is NOT moving. Push the handle slightly forward. You should see the power drive wheels move in the forward position. Pull the handle back, you should see the power drive wheels move in the reverse position. Some finer adjustment may be necessary.
If the power drive cable has broken away from the old actuator; just try to get the new actuator arm as straight as possible. Using the handle and while observing the cable moving back and forth through the retainer area; move the cable all the way forward, then pull it all the back, try to gauge where the middle of the forward and reverse position would be and lock the cable down. Perform testing procedure as in previous paragraph. Again, some fine readjustment may be necessary.

Poor suction The actual sweeper seems to work ok, but the hose attachment has some suction but not enough to pick up things I think it should and not enough to make the power brush spin. I've checked everywhere I can for clogs, but I can't see anything. And there doesn't seem to be any way to check to hose itself for clogs. I've cleaned out the container and the filters, but there's still a problem.

Check the inlet down by the brush roll, make sure it is open, if it is then the hose itself must have a clog. If the hose comes off, drop something like a marble in one end and see it it comes out the other end, if it doesn't then you have a clog. ...
