Super Shifter As Winch ???

[de_]

Has anyone had good or bad experience trying to us an AM Supershifter as a winch. My big concern is the #4 bolt in the dog and or the connection between the shift shaft and the shift block assembly fails. Last I had one apart, there was a tiny roll pin capturing the shifter shaft. Though it might now be some e-clip or something.
I've heard rumors that a substantially larger diameter pneumatic cylinder (or a force multipler lever) compared to stock 3/4" one is needed for the winch due to the forces. Not sure how the pin or maybe the ball bearing inside the assembly is going to stand up.
