Took the lid off and the drum is decidedly twisted to left hand side!

Re: Hoover Logic 1200 A3786

After a bit of a struggle I’ve managed to fit the new anti twist kit and new brushes.

I have the feeling that I have done something wrong when replacing the brushes.

Stupidly, I took the old ones out before the new ones arrived, so I may have done something wrong?

When the machine tries to engage the motor there is a noise like a Drrrrr Drrrr and no sign of life from the motor. There may have been a slight spark around the brushes but it’s difficult to see.
the drum and motor both turn freely by hand.

Hopefully, I have just fitted the brushes incorrectly, have any of you experts any suggestions and hopefully just tell me that I have done something daft?

I wouldn’t like to think it was a bin job after all this work! :eeek:

I checked the new carbon brushes and discovered that one was only just touching the armature and the other wasn’t touching at all. They were a wee bit tight, so I rubbed them down with emery paper and resolved that problem. Armature was a bit grey and manky so I cleaned that. The noise has now gone but the motor will barely turn and smells a bit hot.
Do you think the motor is knackered?

Re: Hoover Logic 1200 A3786

the wire on the brush where have you put it ?

a lot of people put it on the field coil by mistake and there is a terminal on the brush holder

Re: Hoover Logic 1200 A3786

Not sure how to describe it Dave,
One brush only has one terminal, the other one two that appear to be bridged.

on that side I have 4 terminals two are occupied and the middle 2 are bridged. I have the brush connected to the right hand one.

I don’t think it’s quite the same, I have attached a photo of the way that I have mine.

Re: Hoover Logic 1200 A3786

not sure what you mean

if you mean thats where the brush wire was the answer is no

also both brushes have to be in the correct position you have only pictures one of them
