Those instructions are way better, the only other thing was on page 11 where it shows the bottom stopper to be installed. On page 9 it shows three different diagrams and for the ex220-3 it doesn't show it's used for it, i am just curious if that is correct. Thank you
Ok, i definitely would like to hear that theory, also would you know what system pressure should be?
Sorry for the late reply, but your info was very helpful, machine is working good with the conversion.
Hi , I installed thd kit on my 1993 ex200-3 years ago , it’s been painful , I now have realized that the only way to tolerate using the machine is with all washers removed , but main boom and swing simultaneously still will make the engine stall. My new things to try is to try to find a little weaker spring to replace the one in the small valve body that came with the kit, it’s still stroking too fast , or my next idea is to modify the stopper (make it stick up higher to stop the stroke from going so far , has anyone tried this method of not allowing the stroke to go fully open? And has anyone found similar springs for the valve body but a little weaker ???
I would suggest starting from the beginning, which may seem a bit pointless at first, but you may possibly find another issue that is not actually related to the conversion kit you have installed. Double check your kit installation and try checking signal pressures and flow regulation of the pump with a flow meter and loading valve. I had once installed one of these kits to a pump that had been reconditioned with aftermarket parts. The pump when tested would not regulate and cause an engine overloading fault. The pumps aftermarket headcover was actually the issue and not the conversion regulator kit. Many hours spent looking for an issue outside of the pump when it was in fact the pump itself.
That’s the same as what I did on my conversion
just keep an open mind to the possibility that what you have done for the regulator set up maybe correct and that the issue could be within the pump itself. The valve plate assembly in these pumps are common to pick up in the headcovers and they tend to bind which stops the pump from changing its displacement when under load and this then leads to engine overloading.
