Coned pins for flip axle

That and being on level ground helps

 

Fontains are always hard, they machine pins for a tight fit.
Take to a machine shop and remove a few mm from the thickness and taper the ends.

 

I said I would take a picture if it helped, here's the valve setup I have on my pin on 4th. I hook the air then I use the two valves to fine tune the axle. The blue line goes to the suspension, I close the back one and open the front one that inflates the bags, if I need it down a little I close the front one and open the back. You just have to make sure you open the front one once your hooked up.

 

I tote a little 3 ton bottle jack. Put it under the flip at the pin holes. Work like a champ. Unless it's wet and muddy then it's kinda nasty

 

That works but this is even easier than that.

 

on my Talbert. I just ground down the pins a bit with the grinder to taper them
