All, Put new hoses on a John Deere 1630 disk plow that had not been used in several years. Luckily the cylinders still had hydraulic fluid in them. Greased it up and gave it a try. Worked fairly well plowing with it behind 4430 for almost an hour, until one of the hydraulic hose 90 elbow adapters came loose from Hydraulic Cylinder TY7176. Seems like the threads are not fitting right. I used a new [b:2a90487eca]tractor supply 1/2" male o-ring (3/4-16 thread) by 1/2"female pipe swivel 90 degree adapter (sku#1818024)[/b:2a90487eca] instead of the John Deere adapter AU11849 (JD didn't have them in stock). The male side mates to cylinder. Evidently threads were not the right size or the cylinder threads have been damaged in past. QUESTION: Can anyone read the JD parts details and see if the threads are 3/4-16 on the cylinder. Any guidance would be appreciated. Thank You
