ibnxe,
I really can't tell for sure from the illustrations on the linked post and the BX 23 isn't near me. I did the pressure test and increase on my 24 and I am going to mail the gauge and stuff to my friend to use on his 23. I wanted to find out the pressure setting for the 23 before I recommended to him what to do. From what I have read here I am hoping everything is the same.
I have heard, but don't know for sure, that the 24 will lift more than the 23 and my guess is that is because of bigger sized rams and not a different hyd system.
