I'm thinking of buying my own nitogen test/charging equipment for JD combine Hyd. accumulators with Schaeder valve style fitting.


My book says roughly 800 +/- 100 psi; and also explain the drop test and measurements. (1/2 gallon size)


I haven't seen the actual JD type tooling, but this one I found on this link, sure looks like it will work fine. (And if I find a problem with mine, You guys have posted before, to just use that same tooling, go to combine "recycle yard"  and test a used one, until you find one that holds psi good. = much, much cheaper than new, was mentioned, too) 


Any comments, on this tooling; or any other similiar tooling, would be welcome. Thanks
