Accessing self-propelled cable

The self-propelled does not work. How do I find a diagram of how to access and replace. I need to know if I just need the cable or more parts.

    Ours broke where the cable ties into the housing, probably from picking it up by the handle in the self propel mode. I dont think it needs a new cable, just the part where it attaches in the base. Would anyone know that part number and better yet where to get it from? Also, I could use those exploded views, where did you get them from? Thanks.

    The 'fat' drive belt has sliced a gash in the plastic housing. What caused this? When I opened and removed the housing, should there be a device that keeps the belt from slipping off the drive wheel? Drive wheel slides along the axle...should there be a nut that prevents this?



    Does anyone have an exploded diagram with part numbers and also a how to disassemble guide?

The first thing to do is replace the flat belt (38528035), this belt will stretch after a short period, it is the one that drives the drive mech. Also the cable may have broke, if you look down on the right side, you can see the cable, did it break there or is the #34 actuator(#43143046) that the cable attaches to broke. The cable (#43211019)sometimes breaks on the upper end #14, take the handle off and you will be able to tell.

Move the carpet height control switch to a higher position if the vacuum is difficult to push. If the setting is too low for the carpet being cleaned, the brushes press against the floor preventing the vacuum from moving easily.Set to a medium-high height setting then check.Slide the "Self-Propel" button to the "ON" position if the cleaner does not self-propel. -----------
The self-propel feature operates only when the cleaner switch and the self propel button are both ON. ---------- Try this settings and check.This should help.Thanks.Helpmech.

Hoover wind tunnel won't self propel


There are really two reasons why the self-propelled wouldn't work. It could either be the belts on the vacuum cleaner are stretched or broken. The belts on this model control both the self-propelled transmission, as well as the brush roller. Here's a video that shows you how to inspect the roller brush and belts to make sure that they are installed properly and working. Try this repair first, as this is the easier one to fix.


The other problem if the belts are installed properly that would cause the self-propelled wouldn't work would be the self-propelled actuator arm. There is a cable that starts at the handle of the vacuum, and runs all the way down to the floor head of the vacuum that controls the transmission. As you pull backwards on the handle of the vacuum, the cable pulls this actuator arm backwards, which then turns the wheels backwards, and when you push forward it turns the wheels forward.

The problem with the way it's designed however, is that if you pick up the vacuum cleaner by the handle of the machine rather then using the carrying handle on the back of the vacuum, it causes too much tension on the actuator arm, and will cause the cable to rip right out of the arm.

This is a VERY common problem on this model. To check and see if this part is broken on your vacuum, step on the handle release pedal so that the handle is in the vacuuming position, push the pedal a second time so the machine lays flat on the floor.

Now if you look right behind the height adjustment switch, and the rug / floor switch where the floor part meets the upright part, you should see a cable that connects into the actuator arm. Pull up and down on the handle and look for movement. Is the cable loose with only a nut attached to it, or is it resting in the actuator arm?

Here's a very helpful link that shows you exactly how to replace the actuator arm:

Self-propel switch arm broke off where control cable was attached. Looking for instructions as to how to gain access to that switch arm to replace it.


Greetings from GoVacuum,

This is a farily common repair on this model. What ends up happening is that when someone picks up the vacuum cleaner by the handle of the machine, which on this model also is the controller for the self-propelled transmission, it places too much strain on the actuator arm of the vacuum cleaner.

You can do the best to try and not pick up the machine by the handle, but instead using the carrying handle on the back of the vacuum cleaner, this is distribute the weight much better, and even make the machine seem less heavy, and this will also prevent the actuator arm from breaking again in the future.

Now for fixing your vacuum, Please click the link below for an excellent tutorial on how to replace this part;

How To Replace The Actuator Arm On a Self-Propelled Hoover Windtunnel Upright Vacuum


We have also put together a very helpful video for your vacuum cleaner on how to replace the belts. The belts on this model are also a frequent issue we see with these self-propelled Winddtunnels. In fact, for best results you should change the belts once a year, even if they are not broken, because they do heat up and stretch to a point where they don't work as well as a new belt would. The video also explains how you can maintain the roller brush will help you get the longest life possible out of your belts.

Self propelled feature does not work. I replaced


There is a cable from the handle down to the transmission on this machine that breaks all the time or the cable is mounted to a plastic piece that is broken. That will need to be replaced.

Hoover wind tunnel u5755-900. smoke, smell. self-propel


Can you verify the model number? However, based on your posted description, it sounds like the flat belt is either broken or fell off. to access the belts turn it over and remove the bottom plate (4 screws). the Flat belt will connect to the motor shaft in the back and the large black pulley.

Self Propelled does not work


if you look below the headlamp of your vac you will find a cable that attach's to a piece called the actuator arm. either this piece is likely broke or the cable itself. always work the power drive smoothly or things will break. also could be that the smooth belt is stretched and will cause the same problem. belts should be replaced every 4 months. good news is all parts above should be under $5. dont let anyone tell you that you need a power drive assy, that usually isnt the case. good luck!!!

No suction


Flip the machine upside down and remove the four screws from the baseplate. Replacement should be fairly self-explanatory from there. If it's a self-propel model, note that the v-belt in the front WILL look loose normally, so it does not usually require replacement.
If you have a self propelled model, the belt you need ends in 035, if it's non self propelled it ends in 033.
Contact me if you need more assistance in changing the belt.

I don't know how the end fits back on the replacement cable.


Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Hoover U6437-900 / U6439-900 Windtunnel Vacuum. There is a hook on the bottom of the vacuum and @ the top by the handle as well. You may what to get a schematic or owner’s manual to see how they hook up because of the newer and different Model #’s for Hoover. The Hoover Self-Propelled works on when the handle is lower to a comfortable position then the self-propelled drive may just need and adjustment. There is a self-propelled rod that controls the self-propelled feature and it either needs adjustment or replacement or the part that hold it may be broken but either one can be fixed. So feel free to contact your local vacuum cleaner dealer with questions. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Hoover U6616-900 Windtunnel Bagless Upright
I would contact either the local vac dealer or to contact the Hoover Factory or Manufacturer to get the owner’s manual to get an exploded view of the self propelled cable or have the email or fax the information that you need, but they should be able to send you an owner’s manual so you can try to fix it yourself. You don’t want to exceed the repairs cost to the price of what you paid for it. The decision should be yours, example: if the repairs costs are $200.00 and you paid $279.99 then @ that point you would have to decide if the repair costs are worth or do you want to pay the lower cost of repair and continue on. Just a suggestion... You may want to check with your local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
