NOTE: WE BUY AND TRIED THIS REAMER AND WE FAILED..

. Based on the reaming instruction this is what we do. JF010E-OVERSIZED SECONDARY PULLEY CONTROL VALVE

WE ALREADY TRIED SOME OF THE REAMER LIKE U250E F-57917E-TL16, FOLLOWING THE PROCEDURE WE OVERSIZED SECONDARY PRESSURE REGULATOR VALVE AND IT WORKS GREAT. IN THE SAME PROCEDURE WE OVERSIZED FOR THE FIRST TIME JF010E SECONDARY PULLEY CONTROL VALVE BY USING SPEED HANDLE AND THE REAMER PULL ITSELF THROUGH THE BORE, BUT IT STOP IN A CERTAIN POINT (SEE FIGURE BELOW) THE REAMER CAN NOT GO THROUGH AND WE TURN IT BY HAND FOR ABOUT 1 HOURS AND NOTHING HAPPEN, WE USED DRILL AND IT WORKS VERY LITTLE IN AN HOUR. WE TRY ANOTHER VALVEBODY AND THE RESULT WAS THE SAME. WE ALSO TRY TO OVERSIZE JFO11E SECONDARY PULLEY CONTROL VALVE AND THE RESULT WAS THE SAME IT STOP NEAR THE END. MAYBE WE DONT HAVE ANY TRAINING BUT YOU ALREADY GIVE ALL THE INSTRUCTION. WE ONLY FOLLOW THE INSTRUCTION AND WE NEED SOLUTION FOR THIS PROBLEM
