I cannot find my original post, so here it is again. The crankcase seal (where the gearbox shaft goes through) leaks. I need to replace it. I need to know if this can be done without pulling the engine. There is a 2.5" frame support bar under the shaft that could be cut and re-welded to possibly get to the seal (Good idea - bad idea?). One member said that the engine mounts can be loosened (sp?) to 'jockey the shaft at an angle to get the seal out for replacement. What are my options here?
