782 slowly back to life - when to change hydro fluid

[bpientka]

I have slowly collected parts needed to bring a engineless 782 back to life. While I have tested the hydro basic function (using a drill) it has not been run in years (5-10)

The fluid looks ok and I do plan on doing a hydro fluid change and filter. Including opening rear cover and cleaning out.

My question is should I change fluids before starting things up or should I run it a little bit before doing the change?

Any thoughts?

If your going to change it anyways, do it before you run it. No sense in running a bunch of garbage through the hydro if you intend to change it right after.

Just fill it with genuine Hytran Ultra from the get go and you be set.

Thanks, I also figure when things are drained it would be a good time to pull the pump and replace the cork gasket.
