Out mowing with the AC 160 (leaky seal?)

Got the AC 160 mower out yesterday now that the ditch is somewhat drier here in IL. But man, I am getting a lot of oil leaking onto the deck from the gearbox... Any idea if I can replace the seals on this thing or what to do (or is corn head grease the way to go)?

It does a good job cutting -- but still ran into some mud!

Spent a good... hour out there down in the valley. Hit a log the size of my leg that had fallen in the winter; thankfully the rattle clutch still works good. Will have to get down there with the other tractor and chainsaw and move a few more downed trees.
 
The seal should be available from Motion Industries or Kaman Bearing. With exact sizes, or a number. Jim

Awesome, thanks!

(quoted from post at 14:26:56 06/16/20) Is the gear-box vent open??

I should check that....any idea where the vent is?

I have a manual, but it's in my folk's attic.
 
Maybe on the - plug - you take out to fill oil into gear box?? Or anywhere above the oil level of the
oil in the gear box. On top-- side- to let out air when the oil heats up??

Hmmm seems like I have just "plugs" on both the "fill hole" (that is basically a 90 degree pipe elbow that faces up?), and the side hole which I have always assumed is the "level plug", for how I've always filled it. Don't see a vent in either, unless I am missing something.

Will have to check on top or the back plate maybe?
 
Here's some photos, if anyone wants to point out where they think a breather may already be...

Put it on your "to do list", then put corn head grease in it to get by until it comes to the top of the list :)
