Hello I have owned my 743 for 15 years, maintained it regularly. Today I was plowing snow on the driveway and it came to a grinding stop-barely any drive or boom/bucket lift. Sounds like the main hydraulic pump motor packed in.. it's literally screaming when I lift the cab. I can't stand letting it run anymore in case it creates further damage or grenades! Please note: I was able to keep it in high idle and slowly move (barely) it out of the main driveway. **This was an instantaneous failure, there was no sign of any pore operating performance that I could hear or see prior. No low oil condition. Lookin for your insight, please. I'm mechanically inclined with a shop but haven't had any experience tearing a Bobcat hydraulic motor apart. What am I in for? I noticed some reman sellers online. Any recommendations Are there complete rebuild kits? Thank you in advance!
