I have to replace my main gear over-center links. SB20-155 indicates that on some aircraft it can be done without removing the entire gear. My serial number apparently falls under the category that requires removing the gear. The problem is that one bolt holding the link to the gear cannot be removed easily. Has anybody replaced the link on an older aircraft without fully removing the gear? My shortcuts usually end up taking twice as long as doing things right, so I figured I'd ask.
