I just bought a Komatsu PC27R. I used it a little and all works fine, I changed all the fluids and filters. When changing hydraulic fluid, I used Universal Tractor Hydraulic Fluid from TSC. The premium stuff. Now after using it for around 10 hours the pump is whining when under a load and the bucket cylinder has started to leak a bit. I looked online and found that this machine is supposed to use 10W motor oil in the hydraulics.
Anyone with any experience with this change in oil causing a problem?
