I have a FD731V two cylinder in a Hustler SuperZ. After 800 hrs it started blowing oil from under the flywheel. When I pulled it apart I found the top crank bearing bushing and top crank seal out of the engine housing. I bought a new bearing and seal and installed them. Everything was fine for a few hours and than here came the oil again. Same Problem except now the bearing was turning in the engine housing. The housing must be replaced because it acts as the race for the bearing.
Has anyone else had this problem? I change the oil regurarly and this in a 2007 Hustler. I don't thing that a blocked port would build up enough oil pressure to blow the bearing and seal out. I think it was a factory problem and I will paobablly just buy a new engine.
ANY ADVICE?
Thank You:confused:

Call Hustler and see if anyone else has had this problem on that model and see if they have a solution or, if your lucky they will fix it as a recall, or at least tell you if you can do anything besides change the engine.
