THE SERVICE FLUSHING PROCEDURE FOR ALL CONVERTERS HAS BEEN REVISED DUE TO THE ADDITION OF THE CONVERTER CLUTCH. IN THE REVISED PROCEDURE A PIPE PLUG IS USED TO INSURE THAT REBALANCING IS NOT REQUIRED. THE PIPE PLUG CAN ALSO BE REPLACED IF A LEAK DEVELOPS. FOLLOW THE PROCEDURE BELOW:

1.DRILL A 11/32" HOLE IN THE CONVERTER BETWEEN THE TWO VANE EXTRUSIONS AND ADJACENT TO THE CONVERTER WELD SEAM EDGE. SEE FIGURE 1.

  • A.DRILL THE HOLE TO APPROXIMATE COMPLETION.
  • B.REMOVE THE DRILL BIT FROM THE STARTED HOLE AND COAT IT WITH GREASE TO HOLD ANY METAL CHIPS.
  • COMPLETE DRILLING THE HOLE AT LOW DRILL SPEED. NOTICE: TO PREVENT CONVERTER DAMAGE, DRILL AT RIGHT ANGLES TO THE SURFACE AND SLEEVE THE DRILL BIT SO IT CAN ENTER NO DEEPER THAN 1/4".
