We have a 1980 Seneca II (PA-34-200T). Does anyone know how to or know where I can find the manual to flush the gear hydraulic system? I.E. - do you disconnect the high or low pressure lines and for which cycle?

Also need to find the hydraulic system capacity.

I have the maintenance manual (part number #761-590), but this information is not in it.

I would appreciate any and all help!
