Hoover U4395 Vacuum fan (impeller) broke

The plastic fan (impeller) on my U4395 Custom Convertible broke. I was able to order a new fan, but now I'm having problems taking off the old one. Is the motor pull for the belt right or left hand thread? Also, is there a recommended way to remove the pulley?

I've done these impeller replacements on two different Hoover convertibles.

Yes it's a left handed thread on all classic convertibles - loosen it clockwise (reverse thread)

After getting married, my wife upgraded the vacuum to one of those fancy looking ones that claims to produce healthy air has a sleak plastic finish. It was a piece of junk - and the old man was right about the old days and I insisted on another Hoover convertible. It was a small victory but my marriage has prospered and our house has been well cleaned by that powerful 5 amp motor and solid beater bar.

We did however manage to break another impeller in the second antique awhile back (you can only vacuum up change and small tools until one goes in wrong):
My second Hoover's spindle was really corroded and the smooth round pulley nut does not have wrench sides and must have needed like 50-100 ft lbs. not inch lbs. but I was experienced from like 15 years prior (and I obviously needed to save grace regarding old vacuums so failure was not an option) How the heck you say? Once the impeller is broken from your failed attempts, You can more easily get a grip on the impeller chunky broken area at the shaft level with the large 1 foot tongue and groove Channellock pliers (no damage to the spindle this way) then a "14 pipe wrench clockwise on the pulley nut while tightly gripping the Channellocks will take it right off. File or lightly grind or sandpaper the marred pulley nut so it doesn't wear on the belt (there will be little teeth marks on the edge no big deal to smooth) - Put the pulley nut back on with automotive thread anti-seaze. The vacuum may outlive you and the next person only has to figure out the reverse threads and won't have to fight the corroded threads.

It should. You can call Oreck and talk with them and give them the serial number off your vacuum and they can look it up and tell you for sure if it will fit or not.

No your motor is going bad. Have you ever owned an electric fan. If you can remember when the motor started going bad on it the fan would quit turning on its own.Your vacuum is doing the same thing. Please call Hoover and order a new one or go to ebay type in the make and model..

My Hoover upright vacuum has gotten very loud. I have checked the roller, belts and hoses but I haven't found anything. What could the problem be? thanks

Most Hoover uprights are a "fan first" design, meaning that all dirt enters the motor , hits an impeller fan and is blown from there into the bag. You will need to open the vac, remove the belt and two C shaped clamps holding the motor in place and remove the 4 screws holding the fan cover. Look for a broken or damaged blade on the fan. It is a threaded fan and can be purchased at most vac shops. Reassemble in opposite order.

How to replace fan impeller on old Hoover upright. Taking off the belt pulley is giving me the problem.

Depends on how old it is ... if it is real old try putting a open end wrench on metal belt pully, and then hit wrench with a hammer i think counter clockwise to loosen

I broke a piece of plastic off my furniture attachment and now it will not spray cleaner or suction. Can I get a replacement and will it suction again?
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Yes, the best 2 places to get the part or to order the part is your local vacuum cleaner dealer in your area or to contact the Hover website or cust serv line @ the Hoover factory that I will list below, if they do not have the part in stock they can order it for you – make sure you hive them the brand name and model # and sometimes they ask for the serial #. 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 steam vac

I had the same problem just before the impeller broke. Lower the handle and check the hose connection at the bottom is not broken. Turn the unit on with the handle down, then check the suction on the accessory hose, leae it disconnected. Take off the bottom container, and check the suction on the round intake tube (lower one towards the front), with the handle up and with the handle down. If the suction increases dramatically when the handle is lowered, the impeller is probably in it's self-destruct stage. (same as mine). Soon the impeller will break off, and BINGO no suction at all.

Good luck!

Hoover Elite II Model # u4689-910 Impeller replacement

I have had to use a dremmel tool to cut the plastic around the shaft, you can also something sharp and a hammer to break away the remainer of the fan. There are no threads on the fan so to keep truning it may or may not get it off. Just have to watch and not damage the motor shaft and housing.
