Recently became the owner of a 75GM loader. I need to change the hydraulic oil. I am not sure if ISO 46 is needed or something else heavier for use in Carolina. Also any advise on this machine would be appreciated.
Michigan/Clark 75? never heard of that one.
Was a popular machine back in the day. Is it a straight 75, 75B or 75C? Someone should be along that knows what hyd. oil it uses.
It's a straight frame built in the 60's, with a Detroit 5043-7101 2 cycle engine. Transmission oil levels are correct but slips after short use.
