Hello all I'm new to this site and have a question. We have a bunch of new spare motors that have to be rotated on a monthly basis. Two of them are plain bearing motors with forced lubrication. Not lift oil just pressure fed. One of them we have a pump set up we manufactured and use 797 turbine oil to feed oil to it just so we can hand rotate it. 797 is a ISO vg 32, which the manufacture calls for. The other motor that has pressure lube calls for ISO VG 68. We were wondering if it would be a problem to use the same 797 if it was just used for hand rotation of motor, that way we wouldn't have to build an entirely new pump skid.
