Is a valve body rebuild kit for the 5HP30 with 160 $ too expensive?
Definitely not.
When you ever have replaced a valve body kit, you will never again think about saving $ by replacing just 2 balls.
To get to the balls, you have to disassemble the valve body!
Do you think yoy can re-use baked on gaskets?
