Hoover Purepower S3155 - Stripdown & Full Restoration!
« on: March 17, 2020, 01:39:40 PM »
A year or so ago, a viewer of my youtube channel sent me this, a wonderfully rare, special edition Hoover Purepower!



It was very complete



Dates from 1997

ila_rendered

And has a see-through cleanerhead

ila_rendered

It's also got a poorly motor


So let's get it apart, and we shall start by removing the cable

ila_rendered

and the tools

ila_rendered

And the hose

ila_rendered

The ends of the hose pop off and unscrew nicely to aid washing the hose

ila_rendered

and the crevice tool can be removed

Now we can remove the post motor filter



Which looks nice*

ila_rendered

The inside of the cover wasn't too bad though

ila_rendered

And gives us a date of 1997 for itself

ila_rendered

The diagram on the back has survived nicely

ila_rendered

Inside the machine looks very grim though



Moving up to the top and we can take the main handle off



Which just unscrews

ila_rendered

Under the handle is another screw

Followed by 2 more under the bag door

ila_rendered

This reveals the wiring

ila_rendered

Hoover still held the royal warrant at this time

ila_rendered

With that off, the PCB that drives it all can be slid out

ila_rendered

The opaque cover plate screws onto the PCB and comes out with it

ila_rendered

ila_rendered

Screws on nicely though

ila_rendered

ila_rendered

This is the slider mech for the speed control

See, seethrough!

ila_rendered

The mains switch seems to mount up top

ila_rendered

ila_rendered

But remove the cover and the switch is actually sideways inside the housing

ila_rendered

This clamp releases the mains cable, which can then be removed easily

ila_rendered

The air pipe can come off the bag full indicator sensor



And with another screw the housing for it all pulls out

ila_rendered

To remove the wires from the housing the horrible spring slip needs to be removed

ila_rendered

Bag door seal can come out now

Bag door time now



Which doesn't take long as there's only one latch here

ila_rendered

ila_rendered

DON'T

ila_rendered

The bag holder unscrews from the back chassis

ila_rendered

bringing with it some of the tool holder from the back which shares its screws

ila_rendered

The bag fill spout can be unscrewed now

ila_rendered

Which brings the rest of the tool holder with it

ila_rendered

Nice bit of build up under here

The filters can now be removed

ila_rendered

And that's the top end stripped! We can move onto the bottom half now

ila_rendered

The hood unscrews

ila_rendered

And the rubber seal pulls off

ila_rendered

ila_rendered

Onto the next layer, and time to take the brushroll out

ila_rendered

The Dyson belt worked well

ila_rendered

Brushroll stripped

ila_rendered

Front bumper removed

Time to separate the two parts now. Flick the locking rings out

ila_rendered

 and remove them

ila_rendered

The two halves will be apart now. I remove the brushroll seals from the bottom and top of the housings

ila_rendered

Wheel glamor cap is popped off

ila_rendered

And the wheel very gently popped off it's stub

ila_rendered

ila_rendered

The broken lock pedal was extracted

ila_rendered

The retaining clip for the front wheels removed

ila_rendered

The front wheels can then be pivoted up and removed

ila_rendered

And split apart further

ila_rendered

The height adjustment plate pops out under the wheels

ila_rendered

And that's the bottom chassis stripped!

ila_rendered

Time to remove the motor cover!

ila_rendered

Which is carbon dust-tastic!

ila_rendered

The motor can be lifted out

ila_rendered

All rubber seals are removed

ila_rendered

It's so filthy!

Onto the motor now!

ila_rendered

Unplug everything

ila_rendered

Slide the thermal cutout away

ila_rendered

Then remove the carbon brushes, and unplug the wires and unbolt the top housing

ila_rendered



Then tap the fancase off

ila_rendered

Remove the fans

ila_rendered

And we can find our utterly shagged bearing!

ila_rendered

Remove that, and find a replacement

Then wash everything!

ila_rendered

Clean everything else that can't be washed

ila_rendered

Polish everything that can be polished

ila_rendered

Then it's time to re-assemble it



Starting with the new bearings on the armature

ila_rendered

ila_rendered

Then fit the armature to the fancase



Fans on (the fan was washed as well)

ila_rendered

Then the fancase goes on

Top holder can go on now over the coil once fitted

ila_rendered

ila_rendered

Then everything is wired up

ila_rendered

Moving onto the machine, and the bag full air tube, spinal wire and motor housing seal is re-fitted

ila_rendered

Then the motor fitted

ila_rendered

The (much cleaner) motor cover can go back on

ila_rendered

and be screwed down

ila_rendered

Bottom chassis time

ila_rendered

Height adjustment mechanism back on

Front wheels re-assembled

ila_rendered

With a smear of grease to stop the wheels squawking in use

ila_rendered

ila_rendered

Adjuster change plate clipped in

ila_rendered

And the wheels are fitted. Time for a new recline lock assembly

ila_rendered

ila_rendered

Fitted! Along with the rear wheels, which also got a smear of lubrication

ila_rendered

ila_rendered

Brushroll seals pushed back in

ila_rendered

Time to re-build the brushroll

ila_rendered

And refit it

ila_rendered

The top half retaining rings get placed into position now

ila_rendered

And as the top half drops down the rings should close up nicely and hold it all into place

ila_rendered

(Fit a belt at this stage) and fit the bumper and fit the hood cover down onto the lower part

ila_rendered

ila_rendered

Then turn around and see the hood rubber seals behind you, so have it all apart again and fit those

ila_rendered

Bag fill port now!

ila_rendered

Which means the tool holders get fitted too

Bag holder and it's corresponding rear piece

ila_rendered

Then a nice genuine bag!

ila_rendered

Take the shiny bag door

ila_rendered

And fit the latch to it

ila_rendered

Fit the bag door seal

ila_rendered

Then piece the wiring back together for the switch and associated

ila_rendered

ila_rendered

Refit the switch cover to the switch

ila_rendered

Then take the even more see-through after a polish top cover

And fit it to the PCB

ila_rendered

Then fit it all to the machine, along with the cover

ila_rendered



Top handle now. The plastic spacer tube goes in first

ila_rendered

Then the handle afterwards



Re-fit the post motor filter cover latch

ila_rendered

And the cover to the machine



Then lob it all to one side whilst you wait for the postman to come...
