Re: Bosh WFX2867 Carbon brush replacement

Dear All
Some good news. Have replaced brushes and motor is turning. But as soon as I switched on there was rasping sound from the motor. The rasping sound was present when I manually tested the motor before re- installing, so perhaps it has something to do with angle of brushes. I was pretty certain to make sure the angle was correct bu twill check again. Is there a wearing in period for the brushes?
Many Thanks
Lou.

Re: Bosh WFX2867 Carbon brush replacement

thank you. There is a 6 pin ( I think plug) connector lead which I have removed from the motor. And since the pairs are 1+2 etc, it shouldn’t matter if I do test on motor pins from left to right.

Also forgot to thank nomad paul for his comments re the sharp edges on teardrop, Unfortunately for me, I read it too late. ( not too bad a cut though( But other should take note
Thanks again.
Lou

Re: Bosh WFX2867 Carbon brush replacement

thanks very much. Will update you once I have the brushes on Tuesday or Wed hopefully.
One last stupid question re continuity test. Once I have replaced brushes, I set the meter on the continuity setting and take a reading by touching each probe to the carbon brushes?

Thanks very much CJA.
I am going to ask something really stupid. Do I tilt it forward or backwards.
I assume it is forwards to let the motor housing drops slightly forward?
Also is this the same a letting the motor drop down? ( saw it mentioned in one the threads elsewhere) I have also seen some replacement motors for around £130. Hope it doesn’t come to that
Thanks again
Lou

Many Thanks for your responses.
I can remove the bolt in tear drop using ratchet. But not sure how I can acess the other 2 bolts holding motor. They face the other way. Will racthet do it ?
I have a basic multi meter. How would I test the motor?
Thanks again
Lou
