Hey guys Got a bit deeper into the 775; has a bad seal on the input shaft letting it pour fluid into the center gearbox. 2 questions: 1-how do u get that right side unit out? looks to be "wall to wall" drive unit with shafts sticking thru the walls. 2-shows that it could have Vickers or Cessena units; how do I tell which I have? Thanks! Lew
