I'm trying to fix this baby up to (at minimum) good operating condition. She runs well enough right now, but there's some kind of oscillating issue. As you can see from the photos, the washer is worn. With it's "tongue", it should lock on the grooved shaft, but the tongue is nearly gone and no longer locking appropriately. So I'm assuming I'll need one of those. Secondly, I don't understand why but the brass oscillating gear engages the worm sometimes, then other moments, it slips. If I grasp the oscillating knob when it's all together and the oscillation is engaged, there is play, enough where I can feel the gear make and miss contact with the worm. Examining the brass oscillating gear, it does not looked stripped. Neither does the worm. What am I missing?    |

change the washer, maybe it is skipping in and out of the groove. Any signs of this on the shaft?, not that you can see thru that sea of bananna pudding in the transmission!!. |

Yes, the washer is definitely skipping, and that is new grease I put in. Where can I get a new washer for this thing? Is that why the gears are not engaging? Doesn't seem like the washer is the only reason... |

While the gear may not be stripped, it's looks so worn that it might as well be and could easily 'skip a beat' while trying to oscillate. I'd be willing to bet that the other brass gear has the same level of wear as well. |

Yeah - to me anyhow, that gear in the first picture looks pretty much shot. It been riding on top of the teeth and has actually worn most of the teeth away. It's been riding in the parts marked red when it should have been riding in the blue. Looks like 50% or more of the tops of the teeth are just gone. I'd guess that both gears probably need to be replaced for that to ever work "just right" again. Attached Image (viewed 121 times): Last edited on Wed Jul 1st, 2009 02:04 pm by Richard Larson |

Gotcha! Thanks guys. I didn't realize I was looking at a worn-down oscillating gear. Now I know. Who reproduces these plus the worm, if I need it? Darryl? |

Evan; Can you post some dimensions of the gear? Like outside diameter, thickness, hole diameter? Even a picture with the gear setting on or near a ruler would work. I'll check my parts and see if I have one. John |

Evan - If you google Boston Gear and look in their online "Open Gearing" catalog under worm gears you might find what you need. Dave |

I would think that your best bet would be to get on the BST and see if anyone has a parts fan with gears you could use. |
