Don't. Use. HyGard.
Yeah. I knew that.
But I gots CRS.
I also gots plenty of HyGard here on hand.
I also just changed out the reverser oil in the 420c today. Sounded fine in forward. Really noisy in reverse! Oops! Now I remember! HyGard is too thin. So, drain it back out and put some heavier stuff in. Ah. Much better!
Problem is I won't do this for another 2-3 years and I bet that pesky old CRS will strike again!

And, yet I didn't put it in the hydraulic system. I *did* remember to not use HyGard there.

I keep other hydraulic oil on hand for the old stuff. Sits right next to the HyGard buckets. And, yet, CRS! Sigh.
