Removing a Trunnion with a siezed Bolt.

[Matt Elan]

You may be lucky using heat on the ends of the bolt but you need a lot of heat to break the bond between the bolt and the bush. Doing heat will eventually burn out the nylon top hat bushes. When I had this problem many years ago on my spitfire there was one solution. Use a thin cutting disc or hacksaw to cut the bolt and bush between the wishbone and the trunnion - there is just enough space in the ‘rim’ of the top hat bushes to do this without damaging the wishbone or trunnion.
If you’ve used heat and burnt out the bushes it can be a bit easier to get the saw onto the bolt and bush.
