...found these on the magnet. It's from an 1886-05. I strained the waste oil but there was nothing else except what appeared to be tiny sparkly pieces in the bottom of the drain pan. There were no strange noises from the transaxle before or after the change. I pushed some dirt with it last night for 1/2 hour and it did fine. This tractor is new to me. Thoughts?

A couple of pieces are bigger than I like to see, but if it's quiet and works good, I wouldn't get bent out of shape. Just run it a few hours and change it again, if you find big pieces again, well you may be headed for trouble, but I'll bet you'll just find the normal metallic sparkle.

When I changed mine the other week I had some filings. Not as big as those bits

 

Tell you what though, a new filter & oil has transformed the drive & deck lift performance :thumbs:

You won't know for sure unless you open up the housing, but my money is on your looking at pieces of your bull gear ( the teeth ) , that size of metal is not a good sign on this particular rear end. Unfortunately Bolens had issues with their "precision cast " internal components on the early Sundstrand pumped rear ends. Eventually it will knock all the teeth off of it. Run it as is ? Your call, it is a problem and it will continue to worsen my opinion based on my experience with these rear ends.

Good points Wrenchin, and I agree, I just don't have the time to tear into right now. I just acquired the tractor and it has a lot of needs. I plan to blow snow with it this winter and I'm getting it ready to do that. Hopefully it will do OK.

Very comman in the early Bolens rear ends that had the Sundstrand 15 pump.  Bolens did not heat treat the bull gear the right way when they were built.    If you need any help or info on this rear end I am just south of you in Mi.
