I needed to work on the eject mechanism. I carefully measured the standoffs on the original part and engineered an alternate plan since I didn't have the time to replicate the part exactly. Instead I opted to buy some off the shel threaded inserts with nylon sleeves.
For the base which holds the eject bracket; I got a 7/8" threaded #8-32 standoff from Master-Carr.com #91125A210. This piece would be mounted to the top with an #8-32 screw and would provide the rotation point for the eject bracket. To space the arm off the base I went with a 3/8" nylon spacer with 1/4" I.D. and 1/2" O.D #94639A141.
Then goes the bracket arm. For the top of the bracket; I went with a PRess-Fit Drill bushing, 0.25" ID, 0.5" OD @ 3/8" length or #9491A252. I topped it off with two flat washers (think they were 1/4") and star washer and another #8-32 machine screw.
For the plunger arm which goes into the solenoid; I went with a 0.25" tall round spacer with a 1/4" OD and and 8-32 screw thread, #91125A140. The nylon spacer on top was a 1/8" long with 0.25" ID and 0.5" OD.
Here's a picture of the original eject mechanism vs the new one:
Here's the mechanism with the coil and other hardware transferred:
And mounted in the PF:
My only concern is vibration loosening the #8-32 screws holding the threaded inserts in place. As a result; I may end up locktite-ing the screws in place later.
