Our local dealer (Blesch Bros.) told us to use a craftsman 3/4 wrench and set it between the fitting and stop block. This year we used a 15/16 because our hydraulics are having more trouble keeping it held up for long times.  I'm sure there is a "correct" or "book" way but thats what he told us and its worked good for us!  Good Luck!

Lift assist springs were to be used for a soybean header and the combine equipped with auto-header height control. You need to have them as tight as they will go and still allow the header to get down on the ground. Too loose and your hydraulic oil may overheat and the "automatic" height feature won't work as well as it could. Drive tire size and steering tire size dictate the actual setting but I have set many with 12 inches space between the hydraulic hose fitting and the back of the clamp blocks.

Service manual actually says to install a pressure gage at port on header control valve and set springs so as to get 225 pounds pressure on line to lift cylinders.  I agree with Dr Allis. His way has always worked for me.

Corn and bean head I set the block so the 3/4 on the 3/4 craftsman wrench is on the rib the block is against the end of the wrench (about 4 inches). The wheat head I set the block as close to the rib as possible. This way I just let the head down all of the way and the springs carry the weight.

I agree with Dr. Allis. We had a M&W robot header control and you would mess with the springs until the header would not go all the way down and then back the springs off just about a half inch. Ryan
