Replacement 6mm Ball Oiler / Oil Hole Cover / Button Oiler

i just bought a 10 pack from precision Matthews to replace the set that were non-functional on my import rotary table, they work and fit well in the 6mm slot. Prices was right too. They also have 8mm
PM Ball oilers
I was getting ready to order a pack for the Birmingham, then just for kicks I went out and measured the one I just popped out of the cross-slide, and it is 1/4". :(
 
Just curious, what’s the best way to remove the old ball oilers? I have a couple on the cross slide of my PM1127 that need to be replaced (or cleaned out). I think they’re just pressed in.
 
I don't know if this is the ultimate and correct removal procedure . I drilled the top off, removed the ball and spring. Used a tap, maybe m5? cap screw and claw to pry out with a piece of wood under it. They popped out without any surrounding damage. Tapped in with plastic hammer

FInd a sheet metal screw or a wood screw where the outer thread diameter is just smaller than the outer ball-oiler diameter.
Screw the screw into ball-oiler, and use a wrench (or puller) to pull it out.

Thanks, I’ll give it a shot.

Screw in a sheet metal screw and then pull the oiler out. A pry bar or similar works well.
 
Looks like McMaster only has the lidded type in 6mm.
