help with delrin rod repair please

[leaverus]

how in the heck are you guys removing the bearing to get the brass tube out without destroying the bearing?

[bostonkiter]

Best advice I can give: Secure the part with a c-clamp and a few blocks of wood to a table. Position a razor blade / utility knife blade between the flange of the bearing and the housing. Tap LIGHTLY at a few different points around the flange and it should come out.

Good luck.

I think there is a good video on this subject.

I have heated the yoke where the bearing is pressed in, and pushed gently on the brass tube. The bearing pops right out, with a bit of heat.

For replacing broken rods, you don't even have to worry too much about how hot the yoke gets. To a point, the hotter the better. The last time I use that method this, and the only successful time, I heated it with a butane torch enough to partially melt the Delrin and the bearing came out with very little force.

I had to replace one too a few months ago and I used also a heat torch and a cutter knife to release the flanged bearing.
Don't use to much force on the bearing with the knife otherwise you can cut them right through.

Good luck

I poke them out with a small diameter hex driver pushed through from the opposite end and have yet to damage or ruin a bearing. I certainly wouldn't recommend hammering on them using this method though.
