Ringfield 3 pole motor / removal of brass cog

[Stephen-1214472]

Hello

I have a noisy 3 pole ringfield motor in an old HST.

It looks clean and all seems ok, but it traditionally makes a racket and on a post somewhere I read it’s probably my the bearing behind the brass cog.

Can I remove the brass cog?

Should I let oil trickle down behind the cog with it in place or try and remove it?

White lithium grease was also suggested, but this won’t trickle so maybe I can take the cog off and squish some grease on the shaft the brass cog is attached to?

Any suggestions before boredom and frustration take over and I find out the hard way you can’t take it apart

Many thanks

If the "racket" the motor emits is a squealing screech, together with a momentary loss of power, then the cause probably is a dry bearing behind the spur gear.

There is no need to remove the gear: simply apply a very small amount (not a "dribble") of suitable model oil with a pin or straightened paper clip immediately behind the gear and it will percolate down in to the bearing.

Agree with going spares comment also you need to puta spot of oil on the bearing in the front of the motor between the brush holders.

Do you mean here?

Yes they do.

I use fishing reel oil stats in place and lasts a long time and that's not a fisherman's tale.

Hi

Yes that is the spot indicated in your photo

Don't what ever you do remove the brass pinion unless you have to. From my experience once they have been removed and replaced, they slip. I use silicon oil with a nozzle so it gets behind the pinion.
