50 hour Hydro Oil for the non believers

[grm61]

I did my 50 hour service a while back.
I poured my old hydro oil into the buckets the new oil came in, they then sat in my shed for two weeks before I took them to dump at the recyclers.

There has been alot of discussion on whether or not to do the hydro at 50 hrs, here is a pic of each bucket bottom after a couple weeks of sitting before being emptied, this is what had settled to the bottom.

I would say this represents about a third of what was still suspended in the oil, as you could still stir it with your finger and see metalic tracers.

The floaty stuff got mostly poured out when I emptied the buckets, there were pieces as big as a dime.

I can't discern what you're showing us from the pics. What you're showing is what was drained out of the sump, or filters or both? Since it came out of the tractor it would seem it was not going to the filters, and *stayed in the bottom of the sump?
*That is, if the contents of the filters are not included in your bucket mix.

If it feels good do it.

When I did my 400 hr hydro oil change there was a great deal of metal filings stuck to the magnets on the two drain plugs and the magnet inside the hydro filter. Plus there was enough silt (like in your photos) that I felt that changing the oil was a good move (although several folks here said it as not necessary). I have a DK45S where the planetary final drives don't have/need drain plugs, just the two large plugs on the tractor center line. Those big magnets did make it hard to get the threads started when I re installed the plugs (probably the most frustrating part of the job). One tip I should have offered is to put a big piece of cardboard under the tractor to make it easy for you to to slide in and out and around.

That is what was drained out of the tractor sump and rear final drives.
I had ran the tractor around for a while right before I drained the oil to get things stirred up.
The oil from the filters went in my automotive drain pan and into my engine oil waste jug.
The filters were discarded, I did not cut them open.

Drain again after 100 hours and you will get the same silt stuff again.

I think that's why I have one eye that looks off to the side:laughing:

Did you do a Hyd oil change at 50 Hours?

I pulled the strainer on my BX25 at 50 HRs and found the same kind of stuff, tablespoon full. Cut the filter open and found the same. So: I changed the fluid after getting the HST back up to operating temp. Found more stuff. Another new filter. I work my tractor hard for its size (1000 hrs/3 years) so I now change lube, HST fluid, and filters every 200 Hrs. I seem to have gotten all that stuff out as I have found no more. I also had a problem with black gunk in the fuel filter for about 3 changes, that has cleared up now also. I want mine to last for awhile so fluids and filters are cheap insurance especially as I get the fleet discount at NAPA (30-50%).

How many hours do you feel you have added to the life of your equipment.

And as an unbeliever (based on the provided example. Which failure have you avoided?

I have a tractor that was made in 1950 and has exactly TWO fluid changes in it's life span and the last was about 15 years ago.

engine oil more regularly ;-)
IT's still a work horse!
