Title: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 08:39:30 PM
Hi!

Time for another refurb thread, and this one came as one lot of 3. Some we have seen/will see.

[attachimg=1]

From the first generation of Turbopower

[attachimg=2]

[attachimg=3]

From September 1984

[attachimg=4]

[attachimg=5]

I did the usual before video


Then by the looks of it bought it in from the rain and removed the 2 handle screws

[attachimg=6]

Off

[attachimg=7]

The wiring harness locating peg came out next

[attachimg=8]

Pop the switch out

[attachimg=9]

Undo the wires and remove it all from underneath

[attachimg=1]

Bag time now

[attachimg=2]

To get the bag door off, remove the 3 screws on the trunnion cover. Holding the bag door at an angle makes easy access to the 2 top ones

[attachimg=3]

Lift the whole thing off

[attachimg=4]

I don't usually do this but one of them was broken so I gingerly popped the bag door hinges out, and removed them from their holder

[attachimg=5]

[attachimg=6]

The air freshener, which had mutated into some foul, acrid smelling creature comes off next

[attachimg=7]

[attachimg=8]

Then we can remove the latch and handle for the bag door

[attachimg=9]

The bag clip came off the Sainsburys bag and in the bin that went

[attachimg=1]

Onto the bag fill tube now, 2 screws and it pulls out

[attachimg=2]

[attachimg=3]

Wiring cover next

[attachimg=4]

[attachimg=5]

The motor wires can be unscrewed from the block first

[attachimg=6]

and the whole spine cable can be withdrawn, and the handle socket removed

[attachimg=7]

Time to dig out the autoflex housing screw

[attachimg=8]

Sometimes they just pop out, but usually you need to put a screw into them and pull with pliers

[attachimg=9]

All this cable brake is loose and ready to come out now

[attachimg=1]

We can disconnect the brown wire from the Autoflex assy

[attachimg=2]

But first the blue needs to come out, from by the motor. So...

[attachimg=3]

Height adjuster knob off

[attachimg=4]

Baseplate off

[attachimg=5]

[attachimg=6]

Brushroll off

[attachimg=7]

Hood off

[attachimg=8]

Unplug the wires from the motor and pull them through, then the autoflex unit can be removed

[attachimg=9]

The whole cord reel will loose tension, but don't worry about that for now.

Separate the reel and cable guide by removing the plug on the end of the flex.

[attachimg=2]

[attachimg=3]

Then the brake lever can be removed

[attachimg=4]

[attachimg=5]

Wonder WTF all that string is doing there...

[attachimg=1]

The flex has strain relief in the form of this rubber ring around the first loop of flex

[attachimg=6]

To remove, undo the 2 cord terminal screws

[attachimg=7]

And a cord clamp

[attachimg=8]

Then, feeding the flex out of the rubber ring it can all come off!

[attachimg=9]

I bet the Hoover dealer chaps ruddy hated sticking a new cord on an autoflex turbopower!

35+ years of filth can be seen in the bellows

[attachimg=1]

Back up top though, the cord rewind button can be slid out

[attachimg=2]

The choc block unscrews too

[attachimg=3]

Onto the brushroll now, which was a bit peaky...

[attachimg=4]

[attachimg=5]

I don't think it's a genuine roller, although it's in good nick. Never seen a genuine Hoover brushroll axle rust like that.

[attachimg=6]

[attachimg=7]

Under the bearing carriers was certainly a bit filthy

[attachimg=8]

More grot on the other side

[attachimg=9]

Nice worn Quаltex belt here

[attachimg=1]

Belt guard slides out from underneath

[attachimg=2]

Under the hood was very grimy

[attachimg=3]

Motor has certainly not seen a clean for many decades

[attachimg=4]

Original genuine lightbulb is removed

[attachimg=5]

Then we can get to the back chassis pivot clamps!

[attachimg=6]

[attachimg=7]

Very carefully remove the back chassis from the base

[attachimg=8]

[attachimg=9]

Next up is to remove the big motor clamp

[attachimg=1]

Then we can pull the motor out

[attachimg=2]

I presume it's for use in the home...

[attachimg=3]

The anti vibration sponge was pulled off as it's always full of grit and needs washing properly.

[attachimg=4]

This is something you only do on these first generation Turbopowers, remove the front wheel spring clamps! They did away with these very early on

[attachimg=5]

The wheels and spring then come out as usual

[attachimg=6]

Because the axle is particularly dirty, I dismantled the front wheels too

[attachimg=7]

The two tabs holding the stepper for the height control on can be pushed down and off now

[attachimg=8]

Then removed fully

[attachimg=9]

Post by: beko1987 on July 06, 2020, 09:15:22 PM
Furniture guard is removed now

[attachimg=1]

Then the recline lock pedal

[attachimg=2]

Rear wheel caps now (these pop off from behind, never lever them off from the front or you'll snap the tabs)

[attachimg=3]

Then the wheels themselves can come off, removing the small circlip along the way

[attachimg=4]

Nice and un-worn

[attachimg=5]

Time to strip the motor down now. Rubber ends off

[attachimg=6]

Bellows removed

[attachimg=7]

And it's time for wiring! The pictures below make sense to me as I took it apart, but the black wire comes from the first carbon brush

[attachimg=8]

Which is in fab order

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:19:17 PM
Then the red wire goes off to the bulb holder

[attachimg=1]

Which just pulls off

[attachimg=2]

This brown goes from the terminal to coil

[attachimg=3]

The same with the blue on the other side

[attachimg=4]

One last black going to the other carbon brush

[attachimg=5]

Now we need to open the fancase. Pop the 3 metal clips off

[attachimg=6]

and separate the fancase

[attachimg=7]

Using a big flatblase screwdriver in the slot at the back of the belt spindle, turn the fan off the armature

[attachimg=8]

One metal and one fibre washer will sit beneath it. The fan still had sand on it from the before video

[attachimg=9]

Post by: beko1987 on July 06, 2020, 09:22:34 PM
Now, undo the 4 screws

[attachimg=1]

and remove the bottom half of the motor

[attachimg=2]

Depress the tabs locking the carbon brush holders in and push those out and that is all the wiring disconnected.

[attachimg=3]

This rusty mess is easier than it looks. A good small screwdriver will pop the metal lock washer up and out. It might split it in 2, which is fine as it pushes back down, and makes it easier to extract

[attachimg=4]

[attachimg=5]

That done, the field coil can be removed from the motor housing

[attachimg=6]

Then the armature itself

[attachimg=7]

The top bearing has anti vibration stuff over it's bearing

[attachimg=8]

It just pops out

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:25:26 PM
Like so

[attachimg=1]

A bearing puller next gets the bearing off

[attachimg=2]

Then the cooling fan twists off too

[attachimg=3]

It was proper clogged up, this is what makes Turbopower cleaners sound like shit nowadays unless they've been done by a collector.

[attachimg=4]

That done, everything was washed

[attachimg=5]

Dried and..

[attachimg=6]

[attachimg=7]

Polished

[attachimg=8]

Then laid out

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:27:54 PM
It came up really quite well!

[attachimg=1]

[attachimg=2]

And with all the metalwork run over the wire wheel, it was time to fit the armature back together, with a nice new 608ZZ bearing

[attachimg=3]

and the spotless cooling fan

[attachimg=4]

[attachimg=5]

Belt spindle end spring and dampers are refitted

[attachimg=6]

[attachimg=7]

and the armature sat in

[attachimg=8]

Then the coil can be fitted in place

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:31:10 PM
The new fancase bearing can go into place and the old clip re-used

[attachimg=1]

Carbon brushes refitted

[attachimg=2]

The 2 halves can then be screwed together. Once all 4 screws are tight, it should spin freely and sound smooth.

[attachimg=3]

The wiring can start going back on now

[attachimg=4]

Then the fan, with the 2 washers first

[attachimg=5]

[attachimg=6]

[attachimg=7]

This next bit looks worse than it is as I was struggling with a drying up tube, and it's just sat on the top of the groove, so when the fancase is refitted it squashes out evenly.

[attachimg=8]

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:34:08 PM
Any squeezage can easily be sorted with a quick wipe down anyway afterwards

[attachimg=1]

We'll refit the bellows (make sure the lock part of the cable tie is at the top of the motor. If it's at the bottom the bag compartment catches it...)

[attachimg=2]

Time to fit some wheels, with a nice smear of grease on everything

[attachimg=3]

[attachimg=4]

[attachimg=5]

More grease on the pivot point of the recline pedal

[attachimg=6]

and it's fitted along with it's spring

[attachimg=7]

Furniture Guard slotted on

[attachimg=8]

Then the height adjuster bits

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:38:07 PM
The front wheels can be assembled now, with some grease too to prevent re-corroding

[attachimg=1]

Wheels fitted

[attachimg=2]

Wheels retained

[attachimg=3]

Time to fit the motor now, and a smear of washing up liquid/glass cleaner around the small rubber mount, then over the mating face of the large fan rubber mount. Pop the belt spindle end in first and push, the fancase side will slide easily into place ,it's a tight fit. Pop the big clamp on

[attachimg=4]

Time to fit a back chassis. Refit the white recline bush (it only goes on one exact way)

[attachimg=5]

Moar grease

[attachimg=6]

And fit it all together

[attachimg=7]

And clamp

[attachimg=8]

Onto... the autoflex module!

[attachimg=9]

Post by: beko1987 on July 06, 2020, 09:41:40 PM
Our cable is lovely and clean and brown

[attachimg=1]

We start the loop off through the donut

[attachimg=2]

Then it went over the reel, and pulled together. The cord got fitted to the terminals and then the clamp, and adjusted so it sat correctly

[attachimg=3]

Then I followed the service manual

[attachimg=4]

(which does work well, it is fairly easy to do) to refit and tension the reel assembly

[attachimg=5]

[attachimg=6]

Cord brake stuff back together

[attachimg=7]

Helps to hold the flex in place as you do this otherwise it shoots off into the cord reel and you have to tension it all over again!

[attachimg=8]

Screw the 2 cord guide screws in

[attachimg=9]

Post by: beko1987 on July 06, 2020, 09:45:08 PM
Wire the (frankly far too modern) plug back on

[attachimg=1]

And screw the autoflex assembly into place.

[attachimg=2]

Bag compartment loom now

[attachimg=3]

[attachimg=4]

and hidden away!

[attachimg=5]

Now, we can fit the trunnion cover to the rear chassis

[attachimg=6]

and move onto the brushroll! Vibration washer in

[attachimg=7]

Then new (non genuine) brushroll bearings

[attachimg=8]

I found 2 brand new genuine plastic caps too

[attachimg=9]
Title: Re: Hoover Turbopower Autoflex U2198 - Restoration and Rebuild.
Post by: beko1987 on July 06, 2020, 09:47:27 PM
Brushroll assembled

[attachimg=1]

[attachimg=2]

[attachimg=3]

The belt was very worn, so I grabbed another one

[attachimg=4]

[attachimg=5]

Baseplate on

[attachimg=6]

Height knob fitted

[attachimg=7]

A smear of black silicone applied to the busted screw cover to make it less obvious

[attachimg=8]

Handle back on

[attachimg=9]

The bag door latch can be fitted, and the bag door itself snapped onto new hinge brackets

[attachimg=1]

[attachimg=2]

Was then time for some detailing

[attachimg=3]

I found some cracks whilst doing this though, so out with the glue!

[attachimg=4]

[attachimg=5]

And the wax to try and hide this huge scrape

[attachimg=6]

I was finding it hard to sleep at night knowing there was a Dyson belt on this Hoover, so I found a genuine belt and a genuine bulb to replace the blown one

[attachimg=7]

One last look under the hood

[attachimg=8]

[attachimg=1]

Yup, that's better!

[attachimg=2]

[attachimg=3]

And the result of this extensive rebuild? It runs like a dream


Thanks for reading.

Epic rebuild as ever.  :bow:

Is that one for the personal collection or a flogsie? What are they worth nowadays?

Neither, was a refurb job for another collector. One as minty as this one should be rights fetch a few hundred quid, tidy but basic U2332's are fetching 100 now.

I had the Red one that went alongside it (there's a refurb thread on it) and I sold that for 80 which was far too cheap but I needed rid of stuff fast etc.
