Hi there I just picked up a old mustang 345 skid steer and am in process of rebuilding the rams because the seals are shot in them.. so after inspecting the Hydraulic fluids in it ( for the rams and the drive motors on it) . they should really be changed.. I've searched the net and called my local gehl dealer but of course they didn't have a answer for me.. So I'm here looking for a bit of help .. anyone on here have any idea on what fluids should go in the hydraulic rams tank and in the tanks for the drive motors on both sides??? Thanks in advance
