Hi All,
So, just over a year old Zanussi ZWF1431W washing machine changed by someone’s insurance Co because of failed drum bearings.
The plastic tub was sealed but is now it two nice pieces (thanks to my Bosch sabre saw). 😉
The drum pulley removed (two legged puller) and the drum has come out (hide mallet), the brass bush on the drum spindle seems in good nick. I just need to get the bearings and seal out (ran out of time today). The one bearing I can see is a 6206z (cheap / easy enough).
I haven’t looked closely yet but would there normally be fairly specific part numbers on all the bits .. like the drum / spider etc?
Do we know if it is (or isn’t) the same component as fitted into the splittable tubs please (I think I remember someone suggesting it wasn’t)?
Anyway, I’d thought I’d bring those interested in this project and / or helped me previously, up to date.
All the best ..

Re: ZWF1431W now a twin tub! 😉
Can I ask the obvious, how are you going to stitch it back together. Or was this investigative surgery in the course of research?

A bit of both Alex, 🙂 Don Quixote 😉

Well, to be honest I’m not sure yet and I’ll tell you why.
Firstly I wasn’t sure if what would normally be the lugs that are used to carry the (17?) bolts that hold the two halves together contained anything, like a metal barbed spike (something that would have been a one_way_trip type of cpmpressive thing to support the halves whilst being joind (assuming it wasn’t friction welded etc)). To find out I thought the eaiest way was to first cut the tub in half. It turns out they are solid and so I’ll probably simply drill them out to 6mm diameter and use stainless bolts and nylock nuts / washers (same price for 17 of them as one Zanussi bolt)! 😉
Interestingly I have managed to retrieve (nearly intact) the triangular ‘lip’ that used to sit in a mating groove and sandwich the rubber seal that would have been in there on the non welded version. If I could re-glue that to the cut half I might even be able to use one of the std seals, backed up by some silicone adhesive (as opposed to selant) or some of the more industrial ‘snot’ as used on cars by the likes of 3M. Tigerseal also might be worth an experiment.

I couldn’t stand the suspence and have now taken the remaining bearing and seal out. It turns out the worst bearing was the the outer one and that seems to have failed due to water build up between the two bearings (the inner shield of the outer bearing being very rusty). On previous machines I have noticed a hole under casting on the spider allowing this water out? Is this a feature on the ISE Machines, a small hose taking any water from between the bearings to the pump out pump or into a small chamber with a fluid sensor bringing up a ‘Main seal leaking’ LED? 😉
Anyroadup, in case these sound familiar …
Seal:
40.2-72-11/14 CFW 124966700 RWDR-KombiInner bearing: SKF BB1-3241 304049C
Outer bearing was: 62062
Thoughts, If the inner bearing was a double sealed type rather than shielded, if the water had got past the main seal it wouldn’t have had anywhere else to go other than possibly between the inner bearing and shaft. Had the outer bearing also been double sealed and the gap between them ‘drained’, might they have lasted longer (we know that’s not the idea but ..)?
All the best ..

think you’ll find that’s a 6206 -Z (suffix is a single shield/seal , double-suffix =both sides )
If you can’t drill a hole directly from outside tub to inside gap between front seal and front bearing, I’d suggest you assess grooving a “gutter” under the front bearing,to your drain-hole….that should be at least 1/4″ diameter,as the surface-tension of a bead of water will otherwise tend to plug the hole.
forget Stainless bolts, cad/zinc plated/passivated will be fine….all the rest of the tinware in the cabinet is plated, isn’t it?
Yes, the U-pol product appears to be the same as Sikaflex….U-pol is well known for “bog” (body-filler! ) in the motor-trade (aka “kipper” 😀
erm, maybe you can get the mods to amalgamate all your threads on this machine? it’s getting “hunt the saga!Re: ZWF1431W now a twin tub! 😉

Yeah, my bad Steve, can’t read my own writing and obviously wasn’t thinking either!

Understood. I can’t remember if there is enough ‘meat’ in the cast iron bearing carrier for something that big but if there isn’t (and assuming there isn’t a web to drill through that takes me to the outside) couldn’t I drill through the casting through into the back of the tub and out the back of the tub and bond in a length of stainless / rigid plastic tube or fill one of the internal webs with resin or summat?

Look, I *like* stainless ok, and can probably find / buy stainless stuff easier than anything else (trade). And I’m not sure what the rest is? I think it’s either enamelled white steel, plastic, ally or stainless (like the one way hose clips). I think the only plated bits are the top support (although that’s quite big) and the springs.

Good, as I have a tube of it in white. 😉

I wasn’t sure if my other questions were directly related to the other threads or if anyone would see them on the end of the first one? (but I’m happy for them to be anywhere!) 😉
All the best ..
