After a year and a half of table use, I broke the collet locking pin on my PC 890 router. Probably didn't engage it fully or used a bit too much muscle tightening a 1/4" shank bit at one time or another. I've ordered another pin and have it in hand.
Problem is, replacing the pin requires removing a threaded retainer that has no visible means of applying any torque to unscrew it. It is just flush with the housing and there are no holes or slots to use a wrench on.
Has anyone got any suggestions or has run into this before? The parts list/blowup is located at http://media.ptg-online.com/20050113080243_8901.pdf . The pin is part #21 and the retainer screw is part #23.
