Help on repairs!!

[Richard Moody]

The jack flange may need protek on the bushing.  If that does not work a
shrinking solution might work.   But you did try what Bob Davis says?,
press down on the key next to the capstain...if the jack then pops into
place it is a tight key bushing front or center or both.---ric
