Gear damage Baleno

Hello to the Suzuki round, I, for a few years at MT, since 2000 Baleno – Kombi owners have now the rare problem of the gearbox. Since the noises of the bearings were already very annoying, I removed the gearbox and want to replace the bearings. I unscrewed the black transmission cover. Three screws of the bearing cover were broken off and lay around in the gearbox. What must I consider when cutting the gearbox and has already someone the Rep. kit offered in the net about 120,00 1.6 he year 2000, 120 000 km, which always went well, until the end, then something like that. Greetings from Hessen Paul
