2003/05/26 A Rework Procedure is Now Available to Improve the Mounting of the Ripper Valve {5351, 6310}
Track-Type Tractor:
D10R (S/N: 3KR1-UP; AKT1-UP)

Reference: Service Magazine, SEPD0677, 31 March 2003, "Washers in Ripper Valve Mounting on D10R Prevent Loosening"

Vibration in severe applications may cause the mounting bolts of the ripper valve to loosen on the D10R Track-Type Tractor. Use the following procedure in order to rework the existing hardware. Use the parts in Table 1 to complete the change.

  1. Drill out the existing 3/8 - 16 threaded holes with a 9.5 mm (0.37 inch) diameter. Drill these three holes to a depth of 22 mm (0.87 inch). This may not provide 100 percent cleanup of the existing threads.

  1. Use a bottom tap 7/16 - 14 to tap the same three holes with 7/16 - 14 threads. Tap the three holes to a depth of 17 mm (0.68 inch).
