Hey everyone. I'm new to the group. I have an l3600 I bought back in 2001 and have worked the heck out of it and it's been a great reliable machine. Looking at adding a newer to me model. The unit I'm looking at is a 2010 l5240 enclosed cab ac et. It is hst drive. Has roughly 1400 hours on it, and is in a dealers lot. The question I have is the dealer said complete hst drive has been replaced by them and upgraded to 60 series. They said about 100 hours ago it came in with catastrophic hst failure, metal shavings in fluid etc so they replaced the whole hst system. Not sure what would even cause this. Wondering if this is something to be overly concerned about or with the whole new system should it be fine, well as fine as a used unit can be. It is extremely clean other than the failure they described and repaired. I can't find anything about hst failure being a common issue. Any input greatly appreciated.
