Metal twin-tub Hoovers?

Personally I think you, me a Launderess have the right idea here. It's off we all 3 three have a Hoover and a BD WP/KM portable.

Anywho, it looks lie you've found yourself a Hoover 0510. Some points here, the hose WILL break. I goes through the entire machine and gets brittle and hard. Launderess has a stash of these if you're nice ;) The pump should be savable, they're put together much better than the poly-tub later Hoovers, they're somewhat repairable. Usually a good clean and lube works wonders. The little rubber cap on top of the pump where the dial rod hooks in will be the source of much pain. The pump works on the principle of much suction, it either sucks from the spin side or the wash side via a diverter plunger. With the Hoover pump design, what looks like a dust cap is actually an integrated shaft seal for the plastic shaft. Problem is, when this piece starts to deteriorate, it starts sucking air into the pump during draining and reduces the speed of draining greatly. You can't really repair it, it's brittle rubber by this age, but you can get a flat washer and some small o-rings to remedy the situation for the most part.

I have included a link to some pics of my pump tear down. I used some 3-in-1 oil for the impeller shaft. If the bearing isn't worn this should work for lube, if it is worn, I've used automotive wheel bearing grease with success. Silicone/RTV in addition to the o-rings work to seal the pump back up, infact the aluminum base of the pump will probably be eroded enough to where an o-ring on it's own will not work anyway. Don't forget to replace the metal shims where the halves meet. The nice thing about the pumps in the old SS tub models is that it's the same pump the British versions use. Spares can still be had since they were made into the 90's there, but domestics are few and far between. I have NIB one from last year when Woods went under. The pump belts always look like that, it'll hold up for a long time, Also you can't wash in this thing with the lid on, the torque of that fixed drive motor will throw water everywhere. You can also e-mail me if you need any other pics or questions. It's nice to help someone out whose helped me :)

Checkrate/Likes Yes, those are aluminum lids, and almost everything else is sheet metal and stainless steel. It will agitate. It will spin. It won't pump. And it LEAKS. Feel free to chime in! NorfolkSouthern

Checkrate/Likes *Will Have To Look It Up In My Hoover Repair/Service/Parts Ma* But nice looking machine you have there none the less. Same as mine. Just off the top of my head, if the unit will not pump more likely than not the pump is has either choked up and or simply no longer good and requires replacement. Pumps on this model of Hoover TT were the weakest link, and were prone to leaks and such. Good news is that unlike pumps today, the ones in this machine were built to be taken apart and repaired. Bad news is finding replacement parts is often as difficult as finding new pumps. First take the back off the unit and then engage the spin can/pump and see what happens if anything. If the motor is powered up, but the belt will not turn, stop the spinner and gently tug on the belt to turn the pump pulley. You want to see if the thing will move at all and what sort of resistance you are getting. These pumps do not remove all the water from the drains, thus often there is lots of undissloved detergent, muck, hard water minerals and god only knows what else down there. With regular use the pump will move some of this sediment down the drain, however if the unit is allowed to sit unused for long periods of time, the stuff simply rots/drys out into a hardened mass My unit arrived nearly MIB, including under the bonnet, but the pump was a mess, and had to be replaced. If you require parts, check the archives for my posting of what is in my stash, and let me know. Am always willing to do a deal with a club memember! LOL By the way have two MIB Hoover TT pumps for this model, but am sort of "hoarding" as they are darn hard to find, and one never knows when one is going to need a replacement. However as the "Widow and Orphan" fund is rather low, may be tempted to part with one..... LOL L.

Checkrate/Likes *Pump repair* I'll chime in with my 2 cents' worth ... I took apart my pump, cleaned the soap encrustation around the seals, and put it back together, sealing the seam with silicone. Works great now, although I would still like to replace the top rubber gasket on the outside - it's become cracked with age and there is still a very small leakage issue.

Checkrate/Likes *It's definitely the pump* Well, I got the thing apart, cleaned it up, got it to turn, then lubed the rubber O ring with petro jelly. That didn't work. So, I suppose I could try the silicon rubber trick to see if that will do the trick. Here's a shot of the engine compartment from the bottom. As you can see, the pump's drive belt has seen better days. Also, the leak in the pump is where the two bakelite pieces join together. The only thing that holds the pump together is a metal coat hanger thing that snaps over the top!

Checkrate/Likes *The spinner* You can see the rubber piece that goes over the cloths during the spin on the left, along with a partial shot of the owner's manual. I will send a more detailed shot of that as soon as I get the chance.

Checkrate/Likes *One thing worth checking...* if the pump pulley turns freely, it's possible that there may be a problem with the outlet valves. They are made of two rubber cups on a spring which holds one or the other against the washtub or spin can outlets to prevent water flowing from one tub to the other. It seems if the machine is unused for some time, the rubber valve cup that is held shut can stick to the pump body, so that when the valve dial is turned the valve sticks and the spring gets pulled out, meaning the valve stays shut. To check this, disconnect the hoses from the tubs to the pump, and turn the valve dial, checking that the valves both open correctly. Both Hoover TTs I've owned had this problem due to disuse. Hope that's some help!

Checkrate/Likes *Got the pump apart last night* What's happening, is that the O ring between the lower pump body and valve cup is not forming a seal. The valve works fine. Also, the impeller turns freely. I did take a look at macboy91's link, and can see that the pump can be completely dissasembled. So, I will get it apart again and clean the area around the impeller. One note: some of the bakelite is chipped where the clamp latches on, so it may not hold together anymore after I get it apart. So, I may end up having to find a new pump. But I'll do the best I can with what I got. Laundress: Please feel free to contact me through the site. Also, thanks for your help! NorfolkSouthern

Checkrate/Likes *Thanks* Well, I don't see any pumps there that look like the one in mine. But, you do have a black tub drain hose that I could use. The one I have doesn't leak that I know of, but it does look like it's getting a little fragile. The drain hose to the sink seems to be in OK condition, but one of those spares would certainly be nice. More on my pump: I'm starting to get the idea that JB Weld may be the only option I have left. When I get another chance, I may go for it and see what happens. I don't think I can avoid the silicon for the upper valve cup, but I sure am thankful the rubber valves are in good shape.
