silencing a noisy model locomotive

- A few weeks ago I re-motored my freelance locomotive no. 17 William Wallace. This model has an ancient Arnold mechanism and began running erratically. The new motor improved the running, but it remained very noisy. I traced the cause to the knuckle clutch between the motor and the worm shaft. Yesterday I put a little silicone sealant into the clutch, which reduced the noise considerably. Note that the motor and worm shafts need to be aligned exactly to prevent binding.
A rubber sleeve would transmit quietly and still have a little leeway for misalignment. But you've got a good result anyway. !
An elegant solution. Well done
