Some exciting news! First i was able to finally open up the FS5W71C 5-speed Transmission. Turns out the reason i wasn’t able to open it earlier was because had removed the wrong locking spring *lol*. Small part – big problem. This is the one to remove on the main shaft bearing, not the small one in front of the bearing 🙂 Finally disasembled and ready for checking. My unprofessional first check revealed that it’s in quite good condition and no need for a big rebuild, but i will have a professional look over it and definitly will replace a few wear-parts anyway and have the housing repainted. Even better news…
