Does anyone have experience/instructions on removing or replacing the Hoff Valve in a piper Lance?

Just remove the differential girdle-spring and it'll pop right out.
 
My concern is having to replace the orings inside valve requires dismantling the entire back up mechanism..certain parts should not be adjusted per service manual...has anyone dismantled entire system?
 
Paul I saw that post..I would like to to the person that took it apart..don’t want to get anything out of adjustment
