Reply To: MARK 55 NO VACUUM. SHOULD I WORRY

first 20 lb pressure is very high. 7-8 is all you should be doing . seals can be ruined with to much pressure. second that unit is designed for grease not oil. I use john deer corn head grease. y0ou say you did not take the drive shaft out how did you get to the water pump seal ? that is the one that goes bad most of the time.
