At my age, it's not so unusual that my coupler pocket and coupler will sag a bit. I have shimmed the coupler inside the pocket, but the pocket still has quite a bit of sag. The problem is made worse by trying to match it up to a BLI GG-1, which has a naturally high coupler. Before I go opening up the combine, how can I cinch up the sag?

Does anyone have any tips for lubricating the belt drive in a 2-8-0? Like what "grease" to use, disassembly ideas...etc. I need help! My guess is that it most likely laid on the warehouse shelf for quite awahile, and now the belt is making clicking noises...
