Hi
On the hydraulic pump of the model C ; there are 4 balls
- 2 balls for intake valve item 27 , ref number 70915904 , 5/16" , is it correct?
- Another one is the discharge valve ball. But no Item ? and of course no piece number.
- And the last, Releif Valve item N° 7 reference 70915906 . This should be smaller only 3/16" does this size correct ( the others are 5/16")
What is the reference of this discharge ball?  Or the diameter size

Or i am a little confuse , may item 2 with the Insert assy 70213522, there is a second line with Ball discharge same reference than intake,   but they  put qtty = 2 ? why i see only one?
?
