0000001601 BCS ADJUSTMENT

Test data 104742-7641
BCS adjustment procedure 1. At full boost pressure, set so that the full injection quantity is within the specifications (adjusting point). 2. Perform boost compensator intermediate operation point adjustment (pump speed N1, boost pressure P1). 3. When injection quantity at boost pressure P2 and pump speed N2 is not as specified, loosen nut (A) and adjust position of screw (B) so that injection quantity is as specified. The screw position should be within +-1 turn of initial position. 4. The nut tightening torque is T.
