0000001601 BOOST COMPENSATOR ADJUSTMENT

Test data 104742-7671
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.

Test data 104742-7671
Tamperproof installation procedure A:Cap B:Rubber vibration damper C:Nut D:Cap E:Position of break L1:Inspection dimension Fig. 1 Regulating valve seal 1) Insert the cap A horizontally (press fit). 2) After insertion (press-fitting), tighten the cap to torque T1, and confirm that it is not pulled out at load F1. Fig.2 Full load adjusting screw 1) Confirm the position of the rubber vibration damper (B) and then tighten nut (C) to the torque T2. Fig. 3 External-adjustment type cover governor seal 1) Target breaking torque T3
