New to the forum. Searched for answer to my question before posting but did not find any answers, only one post un resolved.
FE290 Oil pressure relief valve: My relief valve ball does not seat on the the seat with a 21 MM free length spring. Ball is loose and not in contact with the seal. I have seen this posted on other sites, but found no answers. This engine burned up the counter balance rod and broke the piston rod. Going back together now and found this issue with the pressure relief valve. Never saw one that the ball was not in contact with the seat. Everything looks great, spring is 21 mm and manual says 19MM minimum, but the ball is loose under the seat. This engine burned up from lack of oil so I am not budging until I understand this issue. Maybe Kawasaki wanted it to bypass some right off the bat. Spec on oil pressure is less than .5 PSI which seemed really low to me.
Is the ball supposed to seat on the seat static? Really need to know the answer to this question. I am tempted to shim the spring to bring it in contact and then using a pressure source, apply pressure to the assy to see where it unloads at. Every one I ever saw had the ball in contact with the seat.
Would appreciate some help here. I know what I am doing with engines, but this baffles me and I do not want the rebuild to go south after start-up. Better to wait and get answers.
thanks
