the specs for two different lubricants (P-38 & P-55) are 135-165 S.U.S. @ 100°F and 194-236 S.U.S. @ 100°F. i believe ISO 32 should work fine for the first oil which is lubricating the headstock gearbox and i'm "thinking" ISO 46 should be the replacement for the second oil though it could be just a touch on the heavy side. the second oil is for the Bilur pump on the feed gearbox and apron gearbox which also feeds the ways on the carriage and crossslide.
any input is appreciated
tnx
