Hey Tony, I was waiting for the next 'chapter' in the standard diesel saga. Good to hear you haven't given up on it.
The hydraulic system on these definitely has the potential to blow up the lift cylinder and or top cover although I think that will only happen if the relief valve is clogged or has been replaced with an incorrect one that has the relief pressure set to high. I cracked open the cylinder on an MF50 because I forgot to set the lift height limit on the quadrant after putting everything back together and the relief valve didn't blow. I once looked at a TO35 for sale that I could tell was blowing the relief valve the entire time the lift was all they way up due to things out of adjustment. All it would take is something to suddenly clog the valve and Bang!
