New here... Into the Aussie Hoover (blackstone type) washing machines

[chlorinedreams]

A look at the seal assembly

In the pic the components in the line 32353401 and below make up the kit

Still will post rl pic, they come supplied all in a sealed bag.

Blackstone

Not sure if this is identical... But not being out of au I have not seen a blackstone machine irl

The link I've posted is for a seal assembly minus bush... Still yet to look through what I have...are not sure if I got one with or without bush....

Machines in this era were fitted with porous bushes, and it was practise for the better to soak these in oil for a day before install or fit and soak for a while before sending back into service

Thanks so much

I will order the kit asap and get started.

Thank you for the write-up, it is really helpful and the cleaning pointers were good too.

I suppose you know this: placing the fill control switch in Special Woolens in any part of a Normal cycle locks the timer where it is. It also opens both water solenoids if it is only on cold before. So if you want an extreme long spray rinse, put the switch to Special Woolens once spraying has commenced. This will also activate both hot and cold water solenoids for a mixed spray.

The Special Woolens switch is actually like a secret menu in these machines. Turning the switch part way between Special W and either hot or cold also does other things to the timer. Interesting to experiment.

Any extra info or pics on the earlier enamel tub seal would be appreciated too. I confess it wasn't too clear to me what you meant when you described them briefly before.

I'll be taking the spin tub out of my 600 soon for a general inspection and clean up - will take pics.

Thanks again Baily

500 and 600 outer tub seals

Hey Baily I saw in your second link (reply 40) main tub seal for 500-600 enamel tub machines. I was under the assumption that these had been discontinued? Is that not so? I had better get one of these too.

Also not sure where the porous bush went ...
And do you think my 40 year old bush would still be any good when I need to do this job on my 600? Right now all is well but I like to be ready.

Incidentally the ad says this bush was for 500-700 machines. That's incorrect. The 700's were the first machines to adopt the plastic outer tub and electric pump FYI

Seal

Thanks for the photo. The part does look exactly like the Blackstone seal.

One difference--I've never seen one separated from the mount and bearing. They were sold as one part, including the ceramic ring that rides on top. Price was less than $100. Fairly common repair job in the Blackstone machines. The spring inside the rubber would get out of shape, so the ceramic ring would not lay flat , causing leaks. Either that, or the bearing would leak.

Whatever the case, it still required removal of inner tub. Many times corrosion would prevent the agitator from lifting up. The diecast part that held the tub onto the shaft was another potential problem. Sometimes it did not survive the disassembly.

There was no avoiding the repair job--otherwise there was water leaking down the shaft.

Kit ordered

Thanks I placed an order for the newer type seal. Do you by any chance have the p/n for the enamel tub seal?

Here's a pic of an old Aussie laundry in Greenwich, Sydney. The machine is a 1980 Hoover 725

 

[chlorinedreams]

Old order numbers

They listed the older assembly as HA075

 

[hoover525]

Rather than HA002?

Rather than HA002?

BTW Merry Christmas guys.

Yeah I see from the research I've done there is a large rubber block mount at the base of the enamel tub machines, and this is no longer available. However I'm told that it's possible to repurpose it with what is available for plastic tub set ups.

Can I please show you what I have and maybe you can say if it's enough to fix a leak on a 600 (enamel tub old style Blackstone) machine.

Check out the oil spatters inside the washer compared to when I first posted. Is this from the oil in the felt bush leaking out?

Thanks again for all your helpful information

Inside oil spatter pics

Here is what the inside of my machine looks like after the leak started. Not sure where this oil has come from?

 

[hoover525]

Here are some pics a friend sent me

Here are some pics a friend sent me of a 600 series tub seal. Just need to work out how I can use this with the items in the pic I posted before. Thanks

 

[blackstone]

In the picture in reply #49, it shows the complete seal. Can you remove the black rubber center piece from the metal base? Perhaps with an arbor press. If so, you should be able to insert the new piece (upper left of reply #47).

As for the oil splatter, how is the gasket between the 2 halves of the transmission?

 

[hoover525]

oil splatter

Hi Fred,

I pulled the machine apart today as the leak had gotten so bad. The oil spatter was caused by water borne oil dipping on to the top of the transmission and then being distributed on the walls of the machine when it spun.

The gasket's fine. There was grease packed in around the tub seal that came down when it leaked.

Interesting thing is that more than 1/2 of the seal was missing. The spring-loaded rubber part and ceramic disk were not in the machine. Only the lower seal that sits in the metal part of the rubber block was there. Amazed it didn't leak before.

Ii am just wondering where the felt gasket goes. Is it under the main seal or on top of it?

Thanks guys

 

[blackstone]

I'm having a difficult time trying to imagine how the machine did not have a waterfall underneath, considering that the ceramic ring was missing. That ring, riding on top of the matching surface of the spring-loaded rubber mount, was what kept the water inside the inner tub; yet allowed for spinning.

I have never seen the felt piece. Even if it were to be used as a spacer, it should have been a waterproof material.

Sounds as if this machine had been taken apart and put back together haphazardly, without the right parts. However, it did seem to work good enough, up to now.

 

[hoover525]

Thanks for that

Well at least I have all the parts now. Could I ask one more question? How does the ceramic part sit? Rubber side up or down? Thanks.

 

[blackstone]

Ceramic side down, so that it rides on surface of the rubber seal.

When installing the ceramic/rubber ring, the rubber will have a tendency to not stay in place, and separate from the ceramic. Use a metal washer to push down on the rubber. This applies even pressure to the rubber, keeping it in place, between the shaft and ceramic.

Do you have any metal washers with the kit? They are used to set the correct height of the spin tub. I am assuming there is a notch in the shaft, which must line up with opening in the agitator mount.

If you need images of this, I could check my service manuals, and scan it in.

 

[hoover525]

Yes please!!

Thanks Fred, if you have time to scan that I would be very grateful. I was advised to put the rubber side down, and I did. Later today I will put it on the proper way. But those scans would be MOST appreciate.

Thanks again for all your help.

Cheers,
Erik

 

[hoover525]

No metal washers in the kit

And yes there is a notch the spin tub has to line up on. I'm lucky - my machine hasn't seen much use and there is hardly any electrolytic reaction to the metal.

Apparently the part with the spring-loaded rubber seal and ceramic disk are almost all gone. I'd better grab another one before it's too late.

Regards
Erik

New 1971 pump

Hi all, recently I found a used 1971 pump in black rigid plastic. Installed it and it works great. So glad to get that cheap white plastic aftermarket pump out. I'll keep it as a spare

 

[blackstone]

Here are a couple of scans, showing the tub mount.

The reason for having the metal washers is to ensure that, when the collector tub is installed, there will be sufficient pressure on the ceramic disk. The disk must touch the top surface of the spring-loaded rubber seal to make it waterproof. Since the height of the collector tub is not adjustable (it lines up with the notch in the shaft), the addition of metal washer underneath it might be necessary. The service manual does not give this information.

Instead, it gives such "useful" information, like "remove front panel." Duh.
