Took roll bellcrank bushings apart as they were binding a bit when I torqued up the bole that passes through the bushing. The bush should be long enough to allow free motion of the bellcrank on the bush with the central bolt torqued. Mine were a bit tight, so they came out, reamed the bellcrank hole a little, sanded the bushing with 400 grade sander and then re-assembled. Works much better now. Geased up, ready to go!
