Hi!

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

ila_rendered

From the first generation of Turbopower

ila_rendered

ila_rendered

From September 1984

ila_rendered



I did the usual before video


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

ila_rendered

Off



The wiring harness locating peg came out next

ila_rendered

Pop the switch out

Undo the wires and remove it all from underneath

ila_rendered

Bag time now



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

ila_rendered

Lift the whole thing off

ila_rendered

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

ila_rendered

ila_rendered

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



ila_rendered

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

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

ila_rendered

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

ila_rendered

ila_rendered

Wiring cover next

ila_rendered

ila_rendered

The motor wires can be unscrewed from the block first

ila_rendered

and the whole spine cable can be withdrawn, and the handle socket removed

ila_rendered

Time to dig out the autoflex housing screw

ila_rendered

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

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

ila_rendered

We can disconnect the brown wire from the Autoflex assy

ila_rendered

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

ila_rendered

Height adjuster knob off

ila_rendered

Baseplate off



ila_rendered

Brushroll off

ila_rendered

Hood off



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

ila_rendered

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.

ila_rendered

ila_rendered

Then the brake lever can be removed

ila_rendered



Wonder WTF all that string is doing there...

ila_rendered

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

ila_rendered

To remove, undo the 2 cord terminal screws

ila_rendered

And a cord clamp



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

ila_rendered

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

ila_rendered

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

ila_rendered

The choc block unscrews too



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

ila_rendered

ila_rendered

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.

ila_rendered

ila_rendered

Under the bearing carriers was certainly a bit filthy

ila_rendered

More grot on the other side

Nice worn Quаltex belt here

ila_rendered

Belt guard slides out from underneath

ila_rendered

Under the hood was very grimy

ila_rendered

Motor has certainly not seen a clean for many decades

ila_rendered

Original genuine lightbulb is removed

ila_rendered

Then we can get to the back chassis pivot clamps!

ila_rendered

ila_rendered

Very carefully remove the back chassis from the base

ila_rendered

Next up is to remove the big motor clamp

ila_rendered

Then we can pull the motor out

ila_rendered

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

ila_rendered

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



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



The wheels and spring then come out as usual

ila_rendered

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



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

ila_rendered

Then removed fully

Furniture guard is removed now

ila_rendered

Then the recline lock pedal

ila_rendered

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

ila_rendered

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

ila_rendered

Nice and un-worn

ila_rendered

Time to strip the motor down now. Rubber ends off

ila_rendered

Bellows removed

ila_rendered

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

ila_rendered

Which is in fab order

Then the red wire goes off to the bulb holder

ila_rendered

Which just pulls off

ila_rendered

This brown goes from the terminal to coil

ila_rendered

The same with the blue on the other side

ila_rendered

One last black going to the other carbon brush

ila_rendered

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

ila_rendered

and separate the fancase

ila_rendered

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

ila_rendered

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

Now, undo the 4 screws

ila_rendered

and remove the bottom half of the motor

ila_rendered

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

ila_rendered

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

ila_rendered

ila_rendered

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

ila_rendered

Then the armature itself

ila_rendered

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

ila_rendered

It just pops out

ila_rendered

Like so

ila_rendered

A bearing puller next gets the bearing off

ila_rendered

Then the cooling fan twists off too

ila_rendered

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

ila_rendered

That done, everything was washed

ila_rendered

Dried and..

ila_rendered

ila_rendered

Polished

ila_rendered

Then laid out

It came up really quite well!

ila_rendered

ila_rendered

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

ila_rendered

and the spotless cooling fan

ila_rendered

ila_rendered

Belt spindle end spring and dampers are refitted

ila_rendered

ila_rendered

and the armature sat in

ila_rendered

Then the coil can be fitted in place

ila_rendered

The new fancase bearing can go into place and the old clip re-used

ila_rendered

Carbon brushes refitted

ila_rendered

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

ila_rendered

The wiring can start going back on now

ila_rendered

Then the fan, with the 2 washers first

ila_rendered

ila_rendered

ila_rendered

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.

Any squeezage can easily be sorted with a quick wipe down anyway afterwards

ila_rendered

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...)

ila_rendered

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

ila_rendered

ila_rendered

ila_rendered

More grease on the pivot point of the recline pedal

ila_rendered

and it's fitted along with it's spring

ila_rendered

Furniture Guard slotted on

ila_rendered

Then the height adjuster bits
