This aftermarket ball guide pin for the Rexroth A10VO pump has an incorrectly shaped head - you can still mount it, but you will have to cut the spring support shim a little (make small grooves in the places where the pins work). The part does its job - but if you don't know this detail, you will struggle to mount these pins into the barrel assembly.
