So, Vitrea 41 is (was) 100 grade. Might have some of that..
You are quite correct here - 8 hours of running a machine at the limit is very much not what I’m going to be doing with this.I wonder if we should think about this a little. For a general circulating oil, 100 grade seems to me too thick. Perhaps we are misinterpreting the lubrication plate.
Where it says 'gears and oil nipples', it may mean 'exposed gears' rather than the internal gearbox (and Gamet spindle bearings, etc.). Where do the oil nipples lead to? That might give some qualitative indication of the sort of gears that are suitable for the same oil.
90 weight oil is used in back axles, where the crown gear and differential are partly submerged in it. That seems to me to be a very different situation to a circulating oil. Maybe you can make some judgement of the oil weight currently in there when you drain it.
Even if it is a heavy oil, its original specification would have been for hard industrial use - 8 hours a day, 5 days a week. You are never likely to stress the machine that much. If you put something too heavy in it, the oil will never warm up and circulate properly. Trying to push a thick oil around in a cold workshop will also make the motor and oil pump work harder, drawing more current and if your supply is only just adequate, it may not help you in the winter.
So I took the side covers off, used my sump sucker to pull 2 and something gallons of sh1t out, cleaned with my pump action applicator full of heating oil, and refilled with 15/40 semi synth engine oil. Now I smell like a heating boiler, wife banned me from the kitchen.You are quite correct here - 8 hours of running a machine at the limit is very much not what I’m going to be doing with this.
It would seem so, hoffman xls is a light duty deep roller, inch and threequarter might be the id or the od - I suspect IDIs that an abbreviation for Hoffmann?
