I suggest you spend some time on the Messicks web site looking at part numbers for both models. It will show you if they are different so you at least know that for certain.
I have a M7040 with cab and FEL. Also have the FEL WSM.
Once thing I have learned is that the hydraulic pressure goes to the FEL first then to the 3 pt and remotes. If you are adjusting the hydraulic pressure and only concentrate on the relief valve above the 3 pt, should the loader relief valve be set low, the adjustment for the rear remotes and 3 pt will accomplish nothing. The main hydraulic circuit goes first to the loader valve and then by a power beyond port to the rear remotes and 3 pt.
If the WSM for the loader would help you, pm me with your email and we can make some arrangements to get it to you.
Good luck with you project.
