Thanks both vitesse, Arctic and Simon, I take apart again and have a look.
Can I ask when the fan is started does should it start with a jolt/ kick? My just starts slowly and builds up speed |

Check all electrical connections including your soldered braid (you did solder them didn't you?). Also, as Vitesse says and with the help of Arctic's picture, look carefully at the condition of the commutator. If the fan was left for a long period after it first gave trouble and a brush wore so badly that its spring popped out of the holder and contacted the commutator, you will have irreparable damage.

i did not solder them as I did not have a 300w soldering iron, so I used the method of joining the using the connectors in the original how to, no good?

Had a look again and cleaned those gaps with a hobby knife, I think that did the trick as it starts straight away, no gradual speed up.
But fan is still rattling, if I spin it manually it is ok, but once on it rattles, any suggestions? |

Could a worn commutator cause the blades to wobble a bit?
I’d like to post a photo of mine, but it’s been so long since I did I cannot see any options to do so. All the springs are perfect, there was a bit of brushes still on two, but my commutator is scored a bit. |

Check that the fan blade is fully secure, sometime over time the tags on the rear wear down so blade could wobble, use a 15mm thin wall socket on the front nut and turn the blade anti-clock wise to make sure it's completely tight, you can even then drill a 3mm hole and add a grub screw.
Purple marks where to drill and add self tapper securing screw, if needed ? 1 2 3 Tags marked with yellow dots. 4
