Kubota B2601 Loader Pressure Relief spring location?

[Rock Crawler]

My buddy has a newer B2601 that he wants to put gauges on and check/shim his loader hydraulics. As is his performance from the loader is such that he will stall out hydraulic lift/curl before ever getting the rear tires to come up. So I told him that I have the gage to install in line, but I am not familiar with his machine and do not have a WSM.

My BX had this pressure relief above the rear PTO shaft, my B2650 has it on the right hand side of the transmission to where you lay under the tractor and reach up between the wheel and the transmission to pull the cover and spring.

Do any of you folks have the location or better yet a picture showing this cover/spring on this B2601?

I also need to get new shims for him to use, I have 2 of the BXpanded supplied shims installed in my B2650, so I found a claim that these are the Kubota shims for the BX/B series... can anyone validate this? I thought that they had a 0.3mm shim as well, but maybe the assumption is that you will stack the 0.1mm and 0.2mm if you need a 3mm?
