Anyone ever replaced the way lube metering valves on a GT-20? Z axis isn't too bad to get to but X looks like it's going to be fun. Honestly might have to pull the turret and table. There has got to be a better way. This is a 2006 machine. Also Haas is recommending mobile 1 5w20 full synthetic over the old vactra 2. Anyone have any thoughts on this? I am trying to clean out the whole system.
