Just wondering if the trim hydraulics are rebuildable. My will bleed off (down) after a period of idle time. Seems this would be a checkball or o-ring on the return side causing this. Fluid level is good, no visible external leakage.
I have heard they are not and need to be replaced and that they can be rebuilt. Seems it would be simple enough if I could find a drawing. I know i should post some sort of mfg/model # & will later but wanted to post before I forgot.
Any words of wisdom regarding rebuilding the unit?
