Hi -Post from lonepine . I Changed the Orings in the #50 back hoe control valve on my JD 440 CID crawler and when doing so a 0.1405 orifice fell out as I trunned it over and did not notice where it came from.Looking in the parts catalog a 0.219 orifice goes in the boom valve and two 0.1405 orifices go in to the swing valve. some one had the control valve apart before and the two other orifices where missing. I had a machinest make me a anohter 0.1405 and the 0.219 orifices . which where not avilable since 1975 from John Deere Sure need info for the right ports locations to install them.
Locations of the 0.219 orifice in the boom valve and the 0.1405 orifice in the swing valve that has two of them. THANK YOU e-mail-----wildcountry_e@msn.com
