Title: Hoover Purepower S3155 - Stripdown & Full Restoration!
Post by: beko1987 on March 17, 2020, 11:39:40 am
A year or so ago, a viewer of my youtube channel sent me this, a wonderfully rare, special edition Hoover Purepower!

[attachimg=1]

It was very complete

[attachimg=2]

Dates from 1997

[attachimg=3]

And has a see-through cleanerhead

[attachimg=4]

It's also got a poorly motor


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

[attachimg=5]

and the tools

[attachimg=6]

And the hose

[attachimg=7]

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

[attachimg=8]

and the crevice tool can be removed

[attachimg=9]

Now we can remove the post motor filter

[attachimg=1]

Which looks nice*

[attachimg=2]

The inside of the cover wasn't too bad though

[attachimg=3]

And gives us a date of 1997 for itself

[attachimg=4]

The diagram on the back has survived nicely

[attachimg=5]

Inside the machine looks very grim though

[attachimg=6]

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

[attachimg=7]

Which just unscrews

[attachimg=8]

Under the handle is another screw

[attachimg=9]

Followed by 2 more under the bag door

[attachimg=1]

This reveals the wiring

[attachimg=2]

Hoover still held the royal warrant at this time

[attachimg=3]

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

[attachimg=4]

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

[attachimg=5]

[attachimg=6]

Screws on nicely though

[attachimg=7]

[attachimg=8]

This is the slider mech for the speed control

[attachimg=9]

See, seethrough!

[attachimg=1]

The mains switch seems to mount up top

[attachimg=2]

[attachimg=3]

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

[attachimg=4]

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

[attachimg=5]

The air pipe can come off the bag full indicator sensor

[attachimg=6]

And with another screw the housing for it all pulls out

[attachimg=7]

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

[attachimg=8]

Bag door seal can come out now

[attachimg=9]

Bag door time now

[attachimg=1]

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

[attachimg=2]

[attachimg=3]

DON'T

[attachimg=4]

The bag holder unscrews from the back chassis

[attachimg=5]

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

[attachimg=6]

The bag fill spout can be unscrewed now

[attachimg=7]

Which brings the rest of the tool holder with it

[attachimg=8]

Nice bit of build up under here

[attachimg=9]

The filters can now be removed

[attachimg=1]

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

[attachimg=2]

The hood unscrews

[attachimg=3]

And the rubber seal pulls off

[attachimg=4]

[attachimg=5]

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

[attachimg=6]

The Dyson belt worked well

[attachimg=7]

Brushroll stripped

[attachimg=8]

Front bumper removed

[attachimg=9]

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

[attachimg=1]

 and remove them

[attachimg=2]

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

[attachimg=3]

Wheel glamor cap is popped off

[attachimg=4]

And the wheel very gently popped off it's stub

[attachimg=5]

[attachimg=6]

The broken lock pedal was extracted

[attachimg=7]

The retaining clip for the front wheels removed

[attachimg=8]

[attachimg=9]

The front wheels can then be pivoted up and removed

[attachimg=1]

And split apart further

[attachimg=2]

The height adjustment plate pops out under the wheels

[attachimg=3]

And that's the bottom chassis stripped!

[attachimg=4]

Time to remove the motor cover!

[attachimg=5]

Which is carbon dust-tastic!

[attachimg=6]

The motor can be lifted out

[attachimg=7]

All rubber seals are removed

[attachimg=8]

It's so filthy!

[attachimg=9]

Onto the motor now!

[attachimg=1]

Unplug everything

[attachimg=2]

Slide the thermal cutout away

[attachimg=3]

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

[attachimg=4]

[attachimg=5]

Then tap the fancase off

[attachimg=6]

Remove the fans

[attachimg=7]

And we can find our utterly shagged bearing!

[attachimg=8]

Remove that, and find a replacement

[attachimg=9]

Post by: beko1987 on March 17, 2020, 12:12:43 pm
Then wash everything!

[attachimg=1]

Clean everything else that can't be washed

[attachimg=2]

Polish everything that can be polished

[attachimg=3]

Then it's time to re-assemble it

[attachimg=4]

Starting with the new bearings on the armature

[attachimg=5]

[attachimg=6]

Then fit the armature to the fancase

[attachimg=7]

Fans on (the fan was washed as well)

[attachimg=8]

Then the fancase goes on

[attachimg=9]

Top holder can go on now over the coil once fitted

[attachimg=1]

[attachimg=2]

Then everything is wired up

[attachimg=3]

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

[attachimg=4]

Then the motor fitted

[attachimg=5]

The (much cleaner) motor cover can go back on

[attachimg=6]

and be screwed down

[attachimg=7]

Bottom chassis time

[attachimg=8]

Height adjustment mechanism back on

[attachimg=9]

Front wheels re-assembled

[attachimg=1]

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

[attachimg=2]

[attachimg=3]

Adjuster change plate clipped in

[attachimg=4]

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

[attachimg=5]

[attachimg=6]

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

[attachimg=7]

[attachimg=8]

Brushroll seals pushed back in

[attachimg=9]

Time to re-build the brushroll

[attachimg=1]

And refit it

[attachimg=2]

The top half retaining rings get placed into position now

[attachimg=3]

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

[attachimg=4]

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

[attachimg=5]

[attachimg=6]

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

[attachimg=7]

Bag fill port now!

[attachimg=8]

Which means the tool holders get fitted too

[attachimg=9]

Bag holder and it's corresponding rear piece

[attachimg=1]

Then a nice genuine bag!

[attachimg=2]

Take the shiny bag door

[attachimg=3]

And fit the latch to it

[attachimg=4]

Fit the bag door seal

[attachimg=5]

Then piece the wiring back together for the switch and associated

[attachimg=6]

[attachimg=7]

Refit the switch cover to the switch

[attachimg=8]

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

[attachimg=9]
Title: Re: Hoover Purepower S3155 - Stripdown & Full Restoration!
Post by: beko1987 on March 17, 2020, 12:29:40 pm
And fit it to the PCB

[attachimg=1]

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

[attachimg=2]

[attachimg=3]

Top handle now. The plastic spacer tube goes in first

[attachimg=4]

Then the handle afterwards

[attachimg=5]

Re-fit the post motor filter cover latch

[attachimg=6]

And the cover to the machine

[attachimg=7]

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

[attachimg=8]

[attachimg=9]

With a brand new height adjustment knob

[attachimg=1]

[attachimg=2]

And some nice new genuine belts

[attachimg=3]

[attachimg=4]

[attachimg=5]

[attachimg=6]

We can glue the tiny piece of damaged plastic back on

[attachimg=7]

[attachimg=8]

Give it all a good coat of wax or 3

[attachimg=9]

Post by: beko1987 on March 17, 2020, 12:34:33 pm
Then give it all a good buff, refit all the tools and call it done!

[attachimg=1]

[attachimg=2]

[attachimg=3]

[attachimg=4]

[attachimg=5]

[attachimg=6]

[attachimg=7]

[attachimg=8]

It looks so much better now it's clean and polished! But does it work any better?


Yep! Another quite rare Hoover saved, another collector has had it for a while now, infact he is on here so maybe we'll get a status update on it in time!

Thanks for reading!

Garish colour isnt it?  :whist11:

It's a while since we've had a good Beko strip down topic.

Super as ever.  :bow:
