this is very bad

I changed the hydro fluid on my 4300 hst this weekend. I bought it used so I don't know the life it had before me. That stuff is not gold in the black bucket it is all the shavings after I poured the hydro oil out of the bucket. The other picture was the metal around the screen. It was caked in clumps. I even saw bits of blue from something I don't know.

Is that a five gallon pail....

 

[darrenjttu]

No its a one gallon

how many hours? did everything work ? only thing really to do at this point is change both filters and if it has a cartrigage filter for 3 point up top change that and refill and use . I have seen some older tractors that have not had proper service with more metal or brass than that if you want you could wash with 5 gallons of diesel fuel then redrain and see if anything else come out

It has over 3000 hours on it. Every thing works. I changed removed the 3 point filter and it had metal shavings in it too. I found some blue bits in there too. I also stripped the threads of that filter so I have ordered another one.

I'm with the Marine. Fill her back up with new filters and run it. After a few dozen hours you might change the filters again and dissect them. But if it's still working fine that is only going to stress you more. Not knowing the history this could be from many things. I certainly wouldn't go on a hunt chasing a failure that isn't bothering anything up to this point.

Yes I have changed all the fluids and I wont go looking for problems. Here is the fuel filter I changed last week and all the junk I pulled out of the sediment bowl.

There is good advice given above. Change filters, fill it up and maybe change just the filters in another month or two. Those probably were original filters and I've seen worse.

A agree that is a lot of trash and filings but why it is there is unknown. Before I did anything else I would want to assess the operation of the tractor and all related hydraulic functions. So if you have replaced the fluid, filters and cleaned the screen, how well does it operate now? I would also recommend you save out some clean buckets to catch the new oil again later.

While the shavings look bad this could have been left over from a previous repair, no way to know. There is also the possibility you have failing parts in the case or pump, I would conduct a pressure test of the hydraulic system and see how it turns out. If the tractor seems to perform well under load and everything appears to work well I would work it hard enough to get the hydraulic oil warmed up fully and then drain again to see how much trash I could get out of it. Check the screen again too. You should get a lot less filings the second time. If you get less filings then refill and use it for a few months and pay attention to any sounds of failure.

If you have refilled the fluids and operate the tractor and have problems then you will need to make the repairs. I would not jump to doomsday conclusions just yet.


edit to add You guys must type faster than me, I agree with the others above good advice and the same as I recommend,

Might not hurt to flush the fuel tank .
