I believe that I may be the person Jon is referring to. I changed out the lower volume pump for one of the newer and higher volume pumps on my ’99 LK3054. It was a simple switch with the only modification being the replacement of two bolts with two long studs and nuts. I did this mainly to run a BH off of the remotes. It works great and I have noticed an improvement in all of the hydraulic systems speed. I particularly like the fast dumping circuit of the FEL now, it actually dumps. I don’t remember the cost but I do remember that it was less than a PTO pump for the BH. All in all I would say that it is a useful upgrade. And of course, everyone here who has had the pleasure of dealing with Jon knows that he is a joy to deal with.
