Hi Jim - thoughtful offer but according to Todds' profile he hasn't visited us for awhile. You might try sending him a personal message.My Router # 315.17380 I've used for 40 years died last week. I would have gone in this week's trash, but I saw your note. I've attached a photo of the whole assembly. I guessing you only need the small gear in the middle. Send me money for postage and it is yours.
