Do you only have the 3 point problem when you have the power loss? The 2 problems are in 2 different areas. If you have an early 1855, you also need to keep those filters ( hydraulic filter and breather filter) in good shape. Gravity works well but you can not restrict the oil supply to the pump. Also you need to filter the hydraulic oil down to 10 micron. Remember the human eye can not see particeles smaller than 40 micron so you are really removing fine contaminates.
