Thread: S2a remote servo unit booster - pics anyone?

Thanks John, that’s how the box came from the previous owner. what would be the least intrusive way to replace the grease with oil? I really don’t want to pull the box out.

I think you'd have to take the side plate off the box to remove any grease
Plus you need to think about why it was switched to grease, probably need to remove the shaft and fit a new O-ring. A bit like swivels, switched to grease when the seal leaks.
Sideplate gasket a few dollars O-ring about 20cents from an O-ring supplier.

You can remove the steering box without removing the wing,have done a few in the past and have 2 more to do.....
