Message: <blockquote data-quote="bttpe" data-source="post: 116817" data-attributes="member: 19457">First thanks to both of you for the reply.  I hope I can communicate the problem well enought to help others that use this site.  The input I get really makes a difference in resolving some of these complicated issues.  Interesting replies.  We have not resolved it yet.  I have the top cover off and all of the oiled dumped (20+ gallons).  Up on jack stands we can force the fwd/rev levers and do not see hyd oil passing by the carrier seal.  We did see a little oil leak out on the floor (the drain plug is removed).  We did pull case drain hoses off both side.  On the right side we did that at the connection to the upper resivoir.  The filters are removed and it flowed 'alot'.  On the left side the hydrostat case drain connects to the motor case drain.  We pulled that filter out and have flow both ways. a) flow out of the hydrostat case drain b) flow out of the drive motor case drain.  I've tried a tee fitting here connecting to the resivoir and it didn't fix it. Notable when we bench tested this setup there was zero hydrostat case drain flow and zero motor case drain flow.  That would not be same today.  Up next we will install a tee fitting on both sides and record pressure of the case drains.  Then we are rebuilding the drive motors using seal kits from Loader Part Source.  I'll remeasure the pressure on both sides (filters out and filters in) and report what is happening.  Thank you.</blockquote>
