We've all seen many indications of "Pond Family frugality" but that's a first.  

 

Likely been into since OE.

Finally got a chance to open up this tranny. Was very anxious to check out the carnage. 

First surprise that I found was that right hand outer diff cover was cast steel, the left hand side was aluminum.  Inspected all gears and every thing look great. Then....I pulled the diff apart. This is where I found the issue, I did a really good job of making "tranny gravel".

 

First the 520 uses different bearings to support the diff side plates,  that have a larger ID. Plan as of now is to turn down the side plates on the outer diff plates so that they will fit in the 1533 bearings that are in the tranny.

The side plates on the 8 speed diff I used for the pictures fit in the 1533 bearings. Unfortunately I have no idea what tractor that parts transmission came from.   

PS I call dibs on any salvageable parts from that 6 speed diff if you ever ready to turn it loose. Especially those pinion carriers.

Carnage indeed ... gives new meaning to grind me a pound... cant find em grind em..

Thinking one of those gears needs to find a place of honor on the tractor. Or made into hitch pins at the least...

Flip the pinions or weld the pinions??

I would say whatever is strongest (weld) but flipping is reversible.

Axle is splined to a gear. Probably the same thing happened as this.

On the fence as to weather or not I will lock the 8 pinion diff

Could you just weld up the LSD diff to lock it and put it back in using the same bearings? Lotsa damage from the grinding teeth floating around. Even the pinion carriers seem a bit gouged out. I suspect that reduced engagement between the pinions and the axle gear is what led to an initial slip and then wreckage.

An option that I had not considered, Thanks.

As long as one can use the stronger 520 end plates? See why not with the mods.
