Mori Seiki MH-1500G need some assistance with TROCHID pump working correctly
Machine was bought used. I inherited it when I took this job before me nobody in the company could even use it. I was hired specifically to grow the machine shop and use the machines. I have operated engine lathes so most of that was straight forward this is a good machine. So far, I have fixed the brake reconnected the carriage lock down bolt and changed the spindle head oil. I was about empty. Now my issue is the Trochoid pump meant to bring oil up and around to spindle bearings. It turns seems to work functionally but does not do as the book says and draw oil up into the trough around the spindle head to oil the bearings. I have verified everything is turning and running. It just does not draw oil up where it needs to go. During operation you should see oil dripping in the sight glass shown in the picture and that does not ever happen. I have had the top cover off and the shafts are spinning. pulled the Trochoid pump it seems to turn properly but still nothing. I feel I am looking over and missing something simple that should solve the problem. Anyone else have this machine or one of the variants that has solved this problem?
