ok I have a 2002 763 and I was getting my chain case flooded with all my hyd fluid so I replaced both carrier seals and one drain case filter (didn't see the 2nd one) well after replacing all that it done good ran it out in the yard for a while and then put it up for about 5 days and the hyd fluid never leaked out so today I went and worked with it and 4 hours later it stops moving and my luck it has no hyd fluid. So I guess I will change the seals again and the other case filter that I never changed. So my question is what is the chance its something else?
