MF 40 lift cylinder

[TonyDeb]

Need some advise. I have a 72’ MF40 industrial that the 3 point stopped working. I tore into it and found the lift cylinder had cracked. I replaced with used part put back together (which was a bit of a learning curve getting all the linkage back together correctly) fired it up and lift had no power still. Tore into it again and cylinder was cracked again! What’s going on here? The pressure relief valve looks pretty beat up and I will replace but wondering what else I should be checking, I do have the manuals. Thanks!

For sure I would replace the relief valve and also check your feed back adjustment. That looks like the cyl. not the piston. Is the tractor killing when you go up with the 3pt.?
