Message: <blockquote data-quote="camelchop" data-source="post: 78273" data-attributes="member: 11226"><p>FOREMOST - I apologize if this is a redundant inquiry. I did perform a search in this forum and the first few pages didn't yield any hits. Earlier this afternoon, I received a call from a buddy who performed some excavation work related to a pad I am getting ready to pour for a double wide to sit upon. He had left his Case 450CT and headed off to another job. I was using it at my property and broke a track. Unbeknownst to all, the unit had a severely worn idler, we assume causing too much lateral movement/improper tension. Eventually the machine found the weakest spot in the track I guess and it ripped. It gets worse.... Now, after retrieving the machine last week, he has experienced an issue with the relief valves, first starting with the machine lifting a full load in the bucket. He took the unit to a shop and diesel was discovered in the hydraulic tank. I put 21.x hours on the unit and filled it twice IN THE PROPER tank on the right side of the unit. He is a great friend, long history, etc. He isn't pointing fingers, but provided reasonably confident assurance the unit was not exhibiting such performance issues prior to it operating at my property/my use. We are unfolding an investigation, but it is doubtful anyone is going to burst forward and accept responsibility for the error if someone did. I had various parties "helping" (or not) during the span which the machine was present. The shop has switched the forward and reverse dump valves, flushed the system, and replaced the fluid. The service technician advised the machine was "on borrowed time" with the drives and possibly the pump. He advised it is currently operating closer to its normal considering its hours, etc. My questions are: a) Is it inevitable the drives will fail prematurely? Like in dozens of hours, not hundreds, or thousands. The unit has 2,700 hours on it now. b) What symptoms would this machine exhibit during operation after the hydraulic system was contaminated initially? (I don't have a threshold for what its normal would be...I noticed, as did the owner when he retrieved the unit, the area of the hydraulic reservoir where it appeared it had been "belching") Would the mixture foam when agitated? c) Does the Case 450CT come with 10W-30 OEM and what would mixing traditional hydraulic fluid into the system do? Same extent as the diesel? I also have a Ditch With 3500 and asked someone to add hydraulic fluid and am wondering if he topped off the wrong machine. Again, in a direct confrontation it is unlikely I will get any party to admit doing so. And regardless, ultimately it is my responsibility to my friend.</p></blockquote><p></p>
