ParticipantThanks Dave. That ebay item is one I contacted the seller about but he says it is not for a WKD28350gb/03 it is for a WKD2835gb/03 but that machine doesn’t exist according to Bosch!!:(
I am also looking at this one as a possibility: http://www.ebay.co.uk/itm/235301013219
What do you think?

Moderatorstill think the one i found is a better bet
if you go to the Bosch site and start typing numbers you get to WKD2835 and Bosch give you a list of possibles. youi can either have a 0 or a 1 after the 5. But none of the alternatives have /03 on the end so the ebay seller has to have mis read the number. Have a careful look at his pics against your motor then it says you can make an offer
the Indesit motor you list looks like it has a smaller pulley and thats a no no

ParticipantThanks Dave,
I totally agree which is why I messaged the seller in the first place and later told him about WKD2835 not being valid. He said he would look into it and get back to me but has not done that so far.
I was going to message him again today but wonder if the best thing would be to simply make an offer on it and take the risk it would be a suitable replacement. At worst it would still provide me with authentic replacement brushes and holders to go on my motor to help it keep running in the interim.
What do you think?

ParticipantJust a follow up to add. Looking again at the item the case structure is slightly different to mine so not sure it is a CSET motor and I had asked him to let me know what the printed details on the top of the case are and he has not done so therefore unable to check its spec.

Moderatorcset motor brushes are used by more than one manufacturer
these should be the same. just look at the pics and the way the carbon is facing the correct way
one thing that worried me about the pictures of your carbons above is the lower one does not seem to be angled on the end the same as the one above. did you have them in the correct position when you fitted them ?Dave

ParticipantWell spotted Dave! When this motor stopped running many months ago one brush was worn to the point of not reaching the commie – hence why it stopped. While I sourced replacement brushes (and in order to keep “my boss” able to do the washing) I found two old brushes from some other motor that were the right width and thickness (but not able to substitute as wires were different and they were just too short). So I ground the ends of the existing brushes flat and removed the wires of these extra brush ends and ground their ends to the correct angle and pushed them in to the holder as a sandwich to try. It worked very successfully (no sparking etc) for a couple of weeks until the new brushes arrived. In fact it was so successful I might (in hindsight) have been better to leave them in rather than having put in what have turned out to be very poor replacements.
I have found these two brush ends again last night so today am going to try the bodge again and see how that goes while looking for the longer term solution.November 22, 2023 at 5:06 pm #488612johnboy183
ParticipantWell the repeat “bodge” went very well using the half brushes from before and the original longer brass holders. I first of all just ran the motor on the floor connected to the loom and it ran well with only tiny intermittent sparking as the brushes moulded to the commie. I also ran it like this using the programmes to execute a spin. The motor ran progressively faster though all its stages reaching 17,000 rpm which would equate to about 1700 at the drum (don’t forget it had no load as it was unconnected). At that speed there was a fair amount of commie sparking but looking at it closely it was all at the edges of the brushes – still bedding in I think – as there was no smoke and the motor casing remained only warm. (Dave – I did video this as you suggested but it was very shaky with a lot of wasted video – will try and edit to shorten and see if I can post it).
I then installed the motor, loaded it with washing and ran a full 2 hour programme while observing for any sparking at the motor. Again at wash speed the sparking was almost non existent and at full spin the drum reached 1300rpm which would be normal as the load was quite unbalanced I suspect. At that speed again there was more sparking at commie but no more than earlier observed and no smoke or overheating.
When the wash finished I ran a spin mode with the drum empty and the drum reached just on 1350rpm.
I then removed the motor and checked the commie and brushes and they showed no overheating or heavy blackening of the commie.
Today I have ordered a set of Ceset brushes and holders and will repeat the above when they arrive.
I contacted the seller of the Indeset motor and asked re the pulley diameter and as you guessed it was 19mm (and mine is 22mm).
The guy selling the Bosch motor with the missing 0 in its description I contacted again but am getting no helpful reply and he still seems reluctant to discuss the model number so that I could go ahead (and he is a big established parts seller!).
A possible solution would be to buy the Indeset motor and swop the pulley from mine to it (as I suspected they are only heat shrunk onto the shaft so removal should be straightforward in my workshop).
Again any comments or thoughts on the above would be very welcome.November 22, 2023 at 6:12 pm #488613electrofix
Moderatoryou cant be certain of the spec of the indesit motor. i agree its most liklely the same but it could have a different tacho coil or other detail. the plug might not be the same etc
as for changing the pulley thats a gamble only you can assessDave

ParticipantOk Dave thanks. Time to just sit and think I guess.
November 26, 2023 at 8:32 pm #488615johnboy183
ParticipantOn my motor label it has
MCA 61/64 – 148/SM7
Anyone explain what these figures relate to so I can understand their importance on sourcing a replacement?
Thanks
