Hoover 875

[beko1987]

Today has been a sad day, a colleague who myself and a few other people were close to passed away on Saturday from a heart attack, so we were all told to do whatever we needed to do today.

So I came home and started to strip the 875 down. The chap that passed was always interested in my hobby, and we talked often about it and other vintage stuff.

So, straight away the bag is almost pretty screwed. To get it out of the top slide I had to bend the slide open and prise the bag out with a screwdriver. A small amount of damage was done, tbh it was pretty un-avoidable

Another general picture

The bag as a whole is ok. It's come up nicely wit ha good vac with the Miele (on very low power) and now doesn't billow out dust when you even think about moving it.

Would I be wise to try and wash it? Was thinking of soaking it in warm water only, several times, so soak for 4 hours, rinse in a clean container, then another soak in warm water with maybe some light detergent, then rinse and dry in the sun. Once it is clean I have a plan to fix the cloth, hopefully involving my stepmum and her sewing machine, with some patches added for strength. This will have to wait for now though.

There was a while load of dust, and alot of short dog hairs. And almost an entire ball worth of string

 

[beko1987]

Had to do this outside.

Also, the handle and cord cover is looking pretty past it. Is there anything I can use to either reverse this or stop it getting any worse?

 

[beko1987]

Another main question, how do I get the fan blades off the motor?

And my favorite picture so far:

Is this what our American friends call a 'coffee-can' hoover?

 

[gottahaveahoove]

Yes, they are the coffee cans.

And, I send condolences for the loss of your friend. It can be difficult.

But, best of luck with your restoration.
John.

 

[beko1987]

Thanks John. Lots of us got together earlier and had a brandy and cigar in his memory!

Stripped her down a bit more

Have got the motor apart now, and cleaned it up. I love the bearings that strip apart completely, so easy!

Re-assembly, I missed a washer, and know think I know where it goes, so that will fix it, it's leaning towards a brush, and trips it's fuse after a few on/off's

I put a belt on her (new 612) and got 9ish seconds of lovely purring and the sound of the brushroll pounding the carpet, then blew the fuse.

Have left it for now, will go back later and repair the motor.

Also had a 20 minute play on the hood with some 0000 wire wool and de-greaser, and it comes up a treat!

Will put some pictures up later, but have a video of the motor without a belt fitted

I have the same problem with some of my early HOOVERS : the handle cover and cable cover get sometime a sort of "rubber cancer" and start disintegrating. I think the plaque that covers the switch were simply "rubberized" with a sort of isolating paint, in order to improve isolation in this risky area, i suppose. Should it get worse, I would scrub it away and repaint the plaque with an ordinary paint that matches with the handle. Rubberized paints are anyway available in shops ( we call it CHLOROCAUCCIU' in Italy ) as it is often used for isolating old swimming pools or ponds, etc ). As far as the rubber handles, I was lucky enough to find a cheap NOS black handle for my model 160 ( which was falling into pieces like a biscuit and disintegrated completely when I removed it to fit the new one ) but still have to find a brown replacement for one of my HOOVER 262....by now I am keeping it "as is" cause I don't feel like fitting a different handle from other models and make a fake...curiously enough, other handles from the same period are perfectly kept and still soft, maybe they were better kept or simply maybe HOOVER Perivale might have used poor quality rubber during the WAR period, who knows ?!
By the way, I try to keep my rubber parts always polished with mineral oil ( the one used for sewing machines ) and sometimes treat them with few PNEUS OIL even if this sometimes give a "sticky" effect that attracts dust more then ever ! Hope this helps ! guido

Cheers for the tip Guido, I think mine are too past it for that, only thing to do to them now is be very careful!

Hit a bit of a block with this now, it won't run!

What happened is:

Ran fine
Stripped it down, re-assembled the motor with a circlip in correctly placed
Motor ran, wit ha slight lean though
Motor vlew the fuse with the belt and brushroll connected, as it pulled the motor even further. Did run like a champ for about fifteen seconds though
Realised where the circlip went, fixed the issue and it did not run at all
Put it in the corner for a month
Had another look the other day, motor spins nicely by hand, cheked the wiring, it looks ok. Changed the fuse in the plug, switched it on and the motor jumped to pin up then blew the fuse...

Where would it be broken!! About to start tracing the wires back to check that I haven't trapped one, but I don't think I have. Mains cable is new (short bit I found for testing purposes, will treat her to new flex when she is working again)

Very positive day yesterday!

Spurred on by a reply on Hooverland (it is still going!), I had half an hour with the 875 yesterday, determined to find the source of the deadness!

So, motor stripped down for the billionth time! (Needs to come apart again in the future for re-sealing but meh)

I unscrewed the cable from the plug at the end, chopped off the ring terminals as it wouldn't fit in the spring and pulled them through. Removed the spring as well.

And immediatly saw this!

'Found' some cable

Choppy choppy

crimpy crimpy

and lots of heatshrink. Also covered the original other cable, to prevent this happening again.

Fed the cable back through the spring, re-connected the plug, re-fitted the spring to the motor housing and pegged it into place

Looks a bit naff, but it is safe, which I suppose is the main thing!

You can't really see it though, so thats ok!

Back together

Happy with that, I connected the handle, put a 3a fuse into the plug and... Nothing.

Some swear words were said, and I started to pack up. However, glancing over my box of crimps, I found some spade connectors which fitted the prongs of the plug, so wired the flex directly to the motor and...



Sounding lovely after the motor rebuild too. Think I need new carbon brushes though, as you can see the sparking is excessive, and they make the tickety noise heard when on.

Excited by this, I unplugged it, put the new belt back on and the belt guard, and saw and heard the beater bar for the first time (and I imagine the first time it's turned either in anger for decades)



Had to push down on the front due to lack of weight from the handle. As you can see, it certainly beats. A hurricane was emitted from the rear too!

So, the issue lies within the handle, so I checked and found enough cable to do a new run up the handle. I only had to remove the socket at the base...

Tapped th wooden dowel out

From Hoover 875

and that's where it went downhill again! The socket was in tight, possibly corroded. I tried several ways, and ended up snapping a massive chunk off. So, my next task is to smash the remains out, and remove the cable. Plan A to re-connect everything is using the spade terminals, and just to be careful when removing the handle. Plan B is to find another socket, but I imagine that's going to be pretty tough!

Still, she runs! Will try to bodge it back together so I can run it around the front room and finally use it for the first time in months!

<span style="font-family: tahoma, arial, helvetica, sans-serif;">Wow, you've put a lot of good effort into bringing this back to working order. When you get it painted, it will look sensational. Congrats!</span>
