I've decided to 'bite the bullet' and replace the old hardened engine mount bushes in my RV-4 with a set of J-1552 Lord mounts in place of the old 71032 Lycoming ones.
I'm told that they are dimensionally equivalent, so no bolt length etc changes.
My plan is to support the engine, loosen all the mount bolts and then replace the bushes one at a time without removing the engine.
Has anyone tried doing it this way or anticipates any problems with my plan?
