Class 110 motor failed

[RogerT]

Hi All,

I have a boxed, Green, Class 110 set, which has been stored for many, many, years. A couple of years ago, I unpacked it and it ran like a dream. Until the lockdown, I have run it maybe 2 or 3 times. Recently, I have been running it frequently until, suddenly, it stopped.

No short circuit. Checked everything, cleaned everything, no luck, except the first time I put the brushes back it ran, then stopped again.Tried power to both brushes, still nothing. I then noticed that if I tried to turn the motor by hand,on the gears, with power applied, it would then run slowly, on its own, in one direction only, then would not restart until the same was done again.

 

Any ideas, please?

Hiya

 

I don't know if this helps or not, but back in April I had a similar thing happen to my Late BR Class J15 - & I also asked for help on this Forum & they help me get it going again - take a look at my video & see what you think - it might give you some ideas to what to do...

 

Hope that this helps  😀

You do not mention lubrication.  Is the bearing where the armature/commutator shaft passes through the metal motor casing lubricated?  If not, a very small amount of model oil behind the metal gear on that shaft may help.  Also the spigots around which the 4 transfer gears rotate.  Are the drive axles rotating freely in the bearings where they pass through the housing?  Also are the brush springs keeping the brushes in contact with the commutator face and are the slots between the commutator segments clear of debris?

[RogerT]

I have tried it with all transfer gears removed. I have removed and reinserted brushes and applied power to brush holders. 

I have now lubricated, as suggested, but it still needs manual assistance to get the motor turning, then will not restart after stopping.

have not been able to thoroughly check the commutator as I cannot separate motor from the bogie. I have applied pressure with flat blade screwdriver but lug will not release and in danger of breaking off.

In that case, it may be that one or more of the armature windings have failed.  If you are unsure of removing the motor from the bogier frame, I would suggest sending the complete bogie to the likes of Scalespeed (www.scalespeed.co.uk) who offer a reconditioning and, if necessary, armature rewinding service.
