Jon,
This may be a bit late now but if you still have trouble removing the
bushes, try the following.
If the bushes were a firm or tight fit when installed, using a hacksaw (or
mini hacksaw blade) through the hole in the bush, carefully cut through the
bush lengthways being very careful not to cut into any of the parent
material around the bush. This will allow the compressive forces on the
bush to be relieved once heat is applied.
If you have access to a lathe, make a mandrel with a small shoulder on it
such that the reduced part of the mandrel fits neatly inside the bush, the
shoulder pushes on the end of the bush and the outside diameter of the
shoulder part is slightly less than the outside diameter of the bush.
After cutting the bush as aforementioned, place the mandrel in the bush and
heat it being careful not to heat the surroundings. (may need a shield to
stop this)
Once the mandrel is hot enough to soften the loctite, push on the mandrel to
remove the bush. You may need to devise some gadget to provide some
mechanical advantage to do this subject to where the bush is and how much
room you will have to work in.
Good luck.
