I'm new and need some help with my John Deere 855 tractor

[Joenicholsonj]

Hello,

My name is Joe! I've owned and tinkered with about army thing that has a motor.
It has 1200 hrs on the motor.
The tractor runs and operates perfectly. I also have a model 70 front end loader and model 7 backhoe.
Today I was changing the hydro oil on my JD855 4WD tractor. When I removed the housing for the internal filter that is in the rear end of the tractor, below the PtO, I found a small, 3/4" square piece of cast aluminum about 1/8" thick in the bottom below the wire mesh filter. I don't know where this broke away from and wonder what I should do next. I did use a bore scope and looked inside to see if I could find where it came from but no luck

Any help would be greatly appreciated.

Thanks!

Welcome from Va, hope you find out that it won't hurt anything!

Thanks! Me too! I have no idea how longs it's been in there. This is the first time I've changed that oil. It's been 3 years and 100 hours since I bought it.

Here is a couple of pictures of the piece.

Welcome to TBN. Not sure what that is. Hopefully someone will come along and know what it is.
