Luke, the noise is kind of a "catch 22" situation. The larger gear on the #3 shaft was originally made out of Phenolic. The phenolic gear silenced the noise. Unfortunately that gear eventually dissolves, thus the gear comes apart. Fortunately you have one that has been replaced with either iron or probably brass. I, on the other hand, can't seem to find a replacement gear for the phenolic since I don't have any specs to give Boston Gear. If you have any suggestions, Im all eyes.
Thanks and good luck,
Greg
