Hello convertible fans! I have a late 80's/early 90's Hoover convertible high performance that I got from eBay almost a year ago and when I got it, it worked pretty good till in December when I was using it it somehow made a weird lawn mower like noise and I was like "What!?",so I thought the belt broke and got caught on the fan but it wasn't it and I thought the fan might have got broken but I checked with a flashlight and it wasn't it either,so I don't know I haven't been using it for almost a year and I hope someone knows the problem because I have know idea.

I have had several plastic base Hoover Convertibles that the plastic brushroll housing either wears or breaks altogether, allowing the brushroll to spin freely in the housing. I would check this first.

Well actually there's no belt on the brushroll now,the brushroll is all good,it's the motor,is there a way I can send you a short video of the vacuum running for a few seconds?

Hello,
You might check the carbon brushes as they can cause loss of power and sputtering. Remove them to check their condition and that they are not stuck in place.
Good luck,
Pete

Hello,
Yes I understand, and to be honest I do not remember how the hood is removed LOL. If it were the Classic Convertible of the 60's & 70's I could tell you in a flash. I know I removed that style of hood many times at the shop. I believe it has 2 phillips/cross screws on the bottom that need to be removed. A picture of the bottom would help my old brain remember or better yet a Vacuumland Member jumping in and telling how to remove the hood.
Sorry I was not able to help,
Pete

Yes....

It is two Phillip head screws on either side if the base, kind of towards the front wheels. That's it, then the hood should lift off.  The motor lifts out when the 4 screws on the base of the motor are removed.

 

In a slightly off subject question...Is that your Kenmore Twinfan upright in your cover pic? I have never seen that model before, if it is, please post some good clear pics of that.

Gabriel,

There's one more clue: the impeller fan. Would it be broken (missing fins)?

One question, whenever I get a new fan for this vacuum, which ones better? The 6 blade or 11 blade? Thank you.

Well good news! I ordered a new genuine 6 blade fan for this hoover on eBay. I took a closer look at the fan and I see a crack spot on it. So maybe someone can tell me how to take the vacuum apart or maybe take it to a decent vacuum shop around Dallas?

There are two Fillips Head screws on the underside of the machine. Take those out. Set the height to HIGH and tilt the handle back 1 setting. Lift the hood off.
Disconnect the belt, then undo the 4 screws that hold the bottom of the motor to the base. Lift the motor and the fan is exposed. Use a big flatblade and while holding the Fan, turn the belt pulley CLOCKWISE to remove it.

Gabriel,

Your Hoover High Performance Convertible is a model U4727-900 if I am right, right?

Anyway, here's a parts diagram and list covering this machine as taken from my big HESCO Hoover Repair Parts Catalog (dated June 1996).

Well I took the vacuum apart and I’m trying figure out if I’m actually doing this right? I didn’t use instructions surprisingly.

Well the new Hoover fan has finally arrived and I’m having a little hard time right now. I’m trying to figure out how I’m going to replace the old with the new. The fan bar is supposed to screw off.

Hold the fan, then with vice grips or a large flatblade, twist the belt pulley CLOCKWISE.

Got it. But when you mean vice grips you mean pliers right?

I’m trying to take the pulley off clockwise but it doesn’t want to.

It will take some substantial force.
Vice grips are pliers that stay locked in whatever you clamp them on with spring tension.

If you still can't get it while holding the fan, push a small screwdriver in this hole (backside of motor) to lock the Armature shaft.

Yes it was a challenge to unscrew that pulley. But I did it!
