About a Massey Fergosun tractor

Hello colleagues, to start I send you a
greeting to all.
I would like to ask you if anyone could give me
a hand with the lifting system of the
Massey Fergoson 1195 tractor.
By mounting the lifting cover of the arms
for the tools they do not want to lift.
My question is that a lever that goes down to hook
with the internal pump is not exactly how it is placed. I have a plane of the explodes, but it does not come out
how the pump is hooked.
When I disassemble the lid I did not realize that by
the hole on the right side, where is the
valvulina level rod can be seen.
If someone could send me a photo of it
or a scheme, I would appreciate it.
