WDD960P 7Kg load
The bearings have done on this washer dryer 1 and a half year old, does this have the 30 or 35mm bearing kit?
Has anyone else done the bearings on one of these 7Kg machines, take it they have a different cross piece?Re: Hotpoint WDD960P bearings gone
Doesn’t list bearings, that suggests it may have the 35mm ones but this is Indesit we are talking about, does have a split tub though. 🙂
It shows the drum spider but there is no separate part number in the parts list, only an inner drum. :rolls:
Might be a case of strip it down first, unusual for the 35mm bearings to fail so soon though. 😕
Re: Hotpoint WDD960P bearings gone
sorry for hte hijack bo/jim but just interested apart from diameter how much difference 5mm actually makes to the lifespan of them? is there any sort of mathematical equation that is used to dictate size of race used? sort of like how ohms law is used to determine cable diameter??
Re: Hotpoint WDD960P bearings gone
Had a few washing macine bearings failing but not the washer dryers, watch when you fit them as i have had a few call backs for noise, and found the rear bearing was loose i usauly fit the bearings and secure them with bearing fit now so far not had a call back on these ones. JJ

I guess its all about load v surface area gandh, the 6207/6206 combo in the 35mm kit will have an easier time dealing with a given pressure transmitted through the drum shaft than the 6206/6205 set up in the 30mm.
Its mainly about the front bearing i would think though.. imagine the sheer leverage on the thing on full spin 😯Re: Hotpoint WDD960P bearings gone
I think its due to the design of the shaft and seal,how come the 6205 and 6204 smaller bearings fitted to Hotpoint 95 series and WM range lasted a lot
longer although the bearings on newer machines with faster spin speeds are bound to wear sooner surely.Mike

Re: Hotpoint WDD960P bearings gone
This always baffles me too. Seems these big bearings fail frequently and catastrophically, shattering the shells.
I wonder if it’s the extra distance / speed they have to travel for the same number of revs. compared to a smaller bearing.
Compare also the tiny bearings and shafts used in spin driers of the past.

A, but spin dryers are upright, very little water in drum either so no massive weight load on the bearings.
I find the WMA 35mm with the later, Rubena water seal have in general been fairly decent.
I have fitted large numbers of rear halfs and bearings with the Rubena seal over the past five years and have not been back to a single one of them for subsequent bearing failure.

Ah, you noticed that, too. Don’t forget they also go about 3000 rpm, albeit with a smaller diameter, and last about 15 years on average. 😆

What amazed me about the first WMA’s was somebody actually got paid to sign off that truly awful seal set up, how in their wildest dreams did they think it would last ?
Or maybe that was the point ❓ Came back to bite them on the arse though ‘cos loads failed within 12 months if i remember rightly 🙂Re: Hotpoint WDD960P bearings gone

incidentally would same bearings on say a 6kg drum that was deep f2b but narrow in diameter wear quicker than those with a shallow drum f2b and widest diameter?
