Pulled the main wheels, pulled all the bearings, cleaned off the old grease, which actually wasn't bad, repacked the bearings with fresh grease and assembled.
I bought an RV3 today... It needs work. It's in rough shape, it needs some love. It will take some time to get it airworthy. It needs the engine baffling replaced, and the cowl needs work, but the engine is strong and in good shape.
