Popped my first transmission

[Sparky-(Admin) 26,511]

  I know the WH isn’t a bulldozer (no I don’t)

  Just driving around looking at flowers (no I wasn’t) 

  So there I was pushing railroad ties with my GT-1600 when it made a weird noise, moved forward another foot and then she went into “infinite neutral mode” . Towed her into the ER and the hubs are good, the trans drive pulley and keyway are good and of course the fluid is clean/full. 
  Jack up and it makes some weird and horrible noises when it’s spun. And one time it actually locked up.  
  Have a few (4 spares) transmissions here so it’ll get a new trans. Busted one is the original 1” axle unit with 4 pinions. I’ll install a trans with a 1-1/8” axles and 8 pinions.

8 speed are no longer indestructible I take it?

  I think I might have been asking to much of it.  I have owned this one for at least 15 years and it’s been worked hard! Never was used for easy leisurely mowing. Always towing and plowing snow dirt and stone (and today it was railroad ties). 
  It does have the weaker of the 8 speeds so it’ll be getting an upgrade with the new trans.

A 4 pinion transmission is VERY different from the heavy duty  8 pinion version.

Never broke one, but I only have 1, 1" 4 pinion 8spd that doesn't get worked.

Something got caught in the gear teeth. 

Open it up because you can't break it any more than all ready broke. Interested to know what let go.

While you have the transmission out, check the mounting plate for cracks.

My money is on the differential - as in one or more of the pinions decided enough is enough. You did not drop the plow first before all this? Very optomistic of you!

@Sparky doesn't need to be optimistic. He has several spares.

Haha! Good eye Bill.

  Actually was just running it on jackstands to see what the transmission would do and how it sounded (both were bad). Was hoping to find a sheared key on the drive pulley. 
  It’s “plowless” now while it awaits surgery.

Gotta open her up just to entertain us, we all need a little tractor porn to start the day.        We want to see Mike up to his elbows in gear oil and parts and pieces.

Surgery, no... transplant, yes. A much easier task when dealing with an early one pedal short frame tractor. To switch yours, you will fill a coffee can with fasteners & small parts - not counting the small trophy fiddely-bits inside the Unidrive...

Gear oil smell wafting into the house! WHO'S WITH ME!!!!

Ah, yes, the unmistakeable lingering fragrance of 90 weight in the drain pan & on the parts! BT, DT.
