Hello everyone im new here and not even sure im in the right place to send a message . I have just acquired a 2006 husqvarna tc450 and it was getting coolant in the oil so I read up on the issue and removed the water pump housing the impeller nut was rusted on and i removed that but when i tried to remove the impeller the shaft slipped out from the bearing about a cm. I couldn’t tell at the time because the engine was still closed up , so being so stupid i reckoned that if it was still ok inside and i turned the rear wheel the shaft would spin but it locked up after about half a revolution and thats where its is where the mistake was made i believe. Is it possible to unlock it by reversing the back wheel im not clued up about engines but im learning fast the hard way hahaa thank you
