Got my Alternators Prime today and I'm having lots of difficulties with the shoulder hinges. Folding them outwards when transforming from truck to robot is a bit stiff, but folding them back inwards is a right pain in the buttocks. It seems like the central pin on which the engine compartment and hood hinges is just a tad too long and hinders the shoulders. I can clearly see marks on the hinges from the pin. Anybody else have this and knows a (relative) easy solution? I'm overseas, so returning is not an option. Thx in advance!
