JD 513 Cutter Seal

RobS · Aug 26, 2002

My rotary cutter is leaking gear oil from the lower seal (below the deck). I have an exploded view showing the parts and am prepared to replace the seal myself if I can. Does anyone know if this can be done by simply removing the blade holder and such, or does the whole output shaft need to come out? I'm sure these gearboxes are pretty generic. Thanks ahead of time for the help /w3tcompact/icons/smile.gif

It appears from the breakdown... after you remove the seal "holder", the output shaft will probably also come out with ease...

You'll want to check the shaft for being true anyways... normally the seal doesn't start leaking unless the shaft has taken a few good hits...
