Ive actually have used a drill . A bit that is same size as the coil opening. The new sleeve will be tough to get in . I usually put a little mill wax on it and goes right in .
Jamb a tiny screwdriver between the coil sleeve and the coil. Tap it in with a hammer and crush the sleeve on itself. Then pull it out.
If the inside of the coil is chewed up or warped I would go ahead and replace the coil and sleeve.
You should not have to force a new sleeve in.
It was a plastic sleeve. Once I folded some of edges towards the middle, the yellow nut driver pushed it right through with a hammer.
Be sure to ohm out that coil, if excessive heat caused the original sleeve to become damaged the coil might be bad and need full replacement.
It’s been a while, but if you have a letter drill blank set a letter x or y drill blank fits nicely in a coil to tap a sleeve out
pound out with nut driver . works well. Start with yellow (5/16) and when end of sleeve is at coil surface, use the green (3/8) nutdriver to knock it out of the coil. The yellow will actually fit inside the coil sleeve after pounding and get stuck if you keep at it, so you may have to switch it as it is flush with coil entrance..
the green is the same circumference as the sleeve so it rests against the sleeve's edging as its pounded out.
you cant use the green from the start as it will slip off the edge of the sleeve.
