Title: Hoover Senior 652a/6525a - Restoration for the ManchesterVacs museum!
Post by: beko1987 on October 29, 2020, 02:53:13 pm
This came my way a fair while ago now, with a brief to make one good one out of 2 if possible. It might be possible...


1 and 3/4 of a Hoover Senior

[attachimg=1]

[attachimg=2]

One with decent original paint, one already re-painted

[attachimg=3]

We have a 652a from 1970

[attachimg=4]

[attachimg=5]

And a 6525c from 1972

[attachimg=6]

[attachimg=7]

I started with the complete one

[attachimg=8]

Bag off

[attachimg=9]

Not too ancient paper bag fitted

[attachimg=1]

Bag holder is in good order

[attachimg=2]

The bag bolt was removed

[attachimg=3]

Don't think this has been cleaned recently!

[attachimg=4]

Took the flange off the bellows

[attachimg=5]

And noticed the nice original fluted flex fitted

[attachimg=6]

As we remove the handle bolt

[attachimg=7]

Luckily we don't need to care about these handles as Stuart had the good set powdercoated I think, so these are just so I can use it

[attachimg=8]

[attachimg=9]

We need these bits though

[attachimg=1]

Bottom handle retaining plate and bolt

[attachimg=2]

This handle has seen some use

[attachimg=3]

Under the handle are 2 screws that hold the little plate on

[attachimg=4]

Which has been smashed about before

[attachimg=5]

Then a cord clamp

[attachimg=6]

Which pulled out of the handle bail casting then could be removed from the cord

[attachimg=7]

[attachimg=8]

Can get into tearing this down now!

[attachimg=9]

Baseplate off first

[attachimg=1]

[attachimg=2]

The belt was a genuine old Hoover one

[attachimg=3]

Time to get the Agitator stripped! One end cap came off

[attachimg=4]

And I could tap the axle through

[attachimg=5]

And strip each end down

[attachimg=6]

These were scrap

[attachimg=7]

Brush strips slide out now

[attachimg=8]

Brushroll done, it's time to get back to the machine

[attachimg=9]

The tool entry port was in good condition, with it's original paint

[attachimg=1]

Rear wheels now. Circlip off on one side

[attachimg=2]

And one wheel washer and clip comes off

[attachimg=3]

Then the circlip that sits behind the wheel can come off

[attachimg=4]

Other wheel was oddly far far dirtier...

[attachimg=5]

Wiring now!

[attachimg=6]

Cover plate off

[attachimg=7]

Which was hiding some grot

[attachimg=8]

2nd switch cover now

[attachimg=9]
Title: Re: Hoover Senior 652a/6525a - Restoration for the ManchesterVacs museum!
Post by: beko1987 on October 29, 2020, 03:12:38 pm
[attachimg=1]

They are a pretty switch

[attachimg=2]

Under the switch box looks like it's been underwater once

[attachimg=3]

Power switch now

[attachimg=4]

Heavily used

[attachimg=5]

[attachimg=6]

We can take the hood off now

[attachimg=7]

[attachimg=8]

And begin to get properly dirty...

[attachimg=9]

Post by: beko1987 on October 29, 2020, 03:16:27 pm
Hood retaining brackets off

[attachimg=1]

Then I found the headlight bulb and laughed

[attachimg=2]

Worked well, can't fault it that!

[attachimg=3]

Time to get the handle bail off, starting with the first circlip

[attachimg=4]

The height adjuster bar falls off now

[attachimg=5]

Then the height adjuster pedal slides off

[attachimg=6]

This is a holder for the flex as it comes down

[attachimg=7]

Moving to the other side, the recline pedal comes off with one screw

[attachimg=8]

[attachimg=9]

With that off, and all circlips removed, the whole bail bar taps out of the handle bail, finally releasing the bag flange lock and spring

[attachimg=1]

And the handle bail is also free

[attachimg=2]

[attachimg=3]

We start by removing the wiring block cover

[attachimg=4]

and finally get rid of the mains cable, which has been looked at before

[attachimg=5]

[attachimg=6]

The flex itself can be pulled out of the external protector

[attachimg=7]

First 2 wires off are for the switch

[attachimg=8]

Then the resistor for the headlight wires

[attachimg=9]

A wire clamp needs loosening

[attachimg=1]

And all of this can be withdrawn

[attachimg=2]

An screw here

[attachimg=3]

removes the wiring connector

[attachimg=4]

Then, the motor can be unscrewed from the chassis. Nice original clean paint came to light!

[attachimg=5]

Sort this out in a second

[attachimg=6]

After the front wheels

[attachimg=7]

Which were Genuine Hoover compared to the rear wheels which were replacements.

[attachimg=8]
[attachimg=9]

The final 2 fingers for the painted chassis was they had painted the bumper too!

[attachimg=1]

and painted it whilst the motor was fitted...

[attachimg=2]

One carbon and link wire removed

[attachimg=3]

More wires and carbons removed

[attachimg=4]

[attachimg=5]

Time to remove the top bearing

[attachimg=6]

Not too filthy

[attachimg=7]

Cooling fan off

[attachimg=8]

And we can remove the screws that allow the motor cover to be removed

[attachimg=9]
Title: Re: Hoover Senior 652a/6525a - Restoration for the ManchesterVacs museum!
Post by: beko1987 on October 29, 2020, 03:30:43 pm
Coil is unbolted

[attachimg=1]

Then the fan is held and the armature is untwisted from the belt spindle

[attachimg=2]

Fan was full of grub

[attachimg=3]

All the fan spacers removed

[attachimg=4]

And I chipped off the rock hard motor seal

[attachimg=5]

[attachimg=6]

And finally I had the nice looking plug off for washing

[attachimg=7]

That's one of them stripped (the 6525c) and ready for washing

[attachimg=8]

And using the bag we removed as a bin for all the rubbish this generates

[attachimg=9]

Time to strip the 652c down

[attachimg=1]

Baseplate was filthier

[attachimg=2]

Belt was way more perished and not a Hoover belt like the other machine

[attachimg=3]

Brushroll was awful

[attachimg=4]

End caps far rustier

[attachimg=5]

[attachimg=6]

Pretty much 0 paint left on this one!

[attachimg=7]

The plastic bushings some of these had hanging on in there

[attachimg=8]

Brush strips were way more worn than the other ones too!

[attachimg=9]
Title: Re: Hoover Senior 652a/6525a - Restoration for the ManchesterVacs museum!
Post by: beko1987 on October 29, 2020, 03:37:04 pm
Also note plastic brushroll end caps, a sure sign of prior work

[attachimg=1]

Tool port cage was far worse paint wise

[attachimg=2]

[attachimg=3]

Switch was just as dirty

[attachimg=4]

Nice front wheels

[attachimg=5]

Stripped underneath

[attachimg=6]

Copy/paste with the motor stripdown, although this did have an original Hoover flex fitted before it was chopped off in the distant past

[attachimg=7]

Out

[attachimg=8]

Motor was a fair bit dirtier

[attachimg=9]

Caked on crap splattered around the cooling fan

[attachimg=1]

And under the fan

[attachimg=2]

Both fans!

[attachimg=3]

Tore the rest of it apart

[attachimg=4]

And had to chip the lower bearing out to uncover it

[attachimg=5]

But, despite all this, the hood was in pretty good condition

[attachimg=6]

Under the filth

[attachimg=7]

Both motors went back together from a big pile

[attachimg=8]

Spins with a small breeze now!

[attachimg=9]

Post by: beko1987 on October 29, 2020, 03:45:32 pm
Agitator shells got cleaned up

[attachimg=1]

[attachimg=2]

And primered then sanded

[attachimg=3]

Both motors are done

[attachimg=4]

And everything else was washed, polished, run over the wire wheel and became ready to go back together again

[attachimg=5]

Built both brushrolls up with new bearings

[attachimg=6]

[attachimg=7]

And cleaned up end caps

[attachimg=8]

[attachimg=9]

The good thing about doing this from 2 machines is I can choose the parts that came out the best, on silly things like these front wheel axles

[attachimg=1]

The best wheels

[attachimg=2]

[attachimg=3]

After lots of polishing the original paintwork is firmly in patina territory, rather than trashed!

[attachimg=4]

Best stick the motor down

[attachimg=5]

Plug all the wires back in and route them all

[attachimg=6]

[attachimg=7]

An brushroll and new belt fitted

[attachimg=8]

These parts were the lesser of a pair

[attachimg=9]

We take a slight tangent here. On both of the machines so far, neither had a complete handle bail's worth of non damaged parts. So I paid postage for this poor old thing

[attachimg=1]

[attachimg=2]

Can't notice much difference tbh...

[attachimg=3]

[attachimg=4]

Especially after I polished the hood

[attachimg=5]

Soon we have lots of parts again

[attachimg=6]

And a correct 652a rear wheel axle

[attachimg=7]

A much nicer lower handle cover

[attachimg=8]

And most needed, a non bent handle bail axle

[attachimg=9]

Time to rebuild

[attachimg=1]

Axle in one side, then fit the spring and flange latch

[attachimg=2]

Wire clip and circlip

[attachimg=3]

Height adjust pedal

[attachimg=4]

A non bent height adjuster bracket came out of the scrapper too

[attachimg=5]

Recline lock can be built up

[attachimg=6]

[attachimg=7]

Rear wheel axle fitted with the space shim

[attachimg=8]

[attachimg=9]
Title: Re: Hoover Senior 652a/6525a - Restoration for the ManchesterVacs museum!
Post by: beko1987 on October 29, 2020, 04:01:44 pm
A non cracked tool port diverter flap came up too!

[attachimg=1]

A spring hole is drilled into the 652a chassis for the height adjuster spring

[attachimg=2]

[attachimg=3]

That's all looking much better

[attachimg=4]

Time to build the cable up quickly

[attachimg=5]

Find a more appropriate bulb

[attachimg=6]

[attachimg=7]

Fashion a bag flange seal out of silicone

[attachimg=8]

And with the handle from the scrapper fitted it looks a fair bit better

[attachimg=9]

It all works alot better too!


I guess we need some up to date pics of it now...

I like doing these sort of refurbs, open a box of rubbish and find a diamond in the rough!

Speaking of which, the 262 wants to come home!

Here's piccies of the 652 today.

[attachimg=1]

[attachimg=3]

I'd like a new badge on the head if one crops up.

262 still needs paint, been raining here constantly, and now it's sunny I'm neck deep in my day job...
Haven't got the kids this weekend, concerted effort is needed
