Message: <blockquote data-quote="Land-Tech Custom Landscap" data-source="post: 122340" data-attributes="member: 22437"><p>I had this happen to mine and it almost drove me crazy!!  This will sound out of this world but my problem was a bad hydraulic hose coming from the chain case filter.  Brdgbldr is correct that it is the seal going bad so I replaced mine.  Sometimes it would last 20 min, sometimes it would last weeks, but eventually it would fail again.  I replaced all of the o-rings in the carrier, nope, that wasnt it, and every time it did this it would pump $50-100 dollars worth of hydraulic oil into the chaincase.  UGHHH  I was going crazy and every bobcat mechanic knew they had the answer but none ever did.  Finally this old mechanic said that the seal is a 2 sided seal and that mine was building up pressure on the outside and pushing it in.  He said check that tiny hydraulic line on the top of the carrier and see if it is blocked or clogged.  I said no way, its brand new.....Guess what, the brand new hydraulic line coming from the chain case filter down to the carrier that was brand new, they had over crimped the fitting.  This would not allow the oil to flow through the line, it would build up pressure against the seal and eventually blow it out (or actually in).  I took the lines off and just tried to blow through them, thats how I found out which one it was.  I replaced the line with another new one and have not had a problem since.</p></blockquote><p></p>
