Tamperproofing-equipped boost compensator cover installation procedure
After adjusting the boost compensator (A) (B), tighten the bolts to remove the heads.
(1)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads.
(Tightening torque T = T1 maximum)
(2)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads.
(Tightening torque T = T2 maximum)
----------
T1=2.9~4.9N-m(0.3~0.5kgf-m) T2=2.5N-m(0.25kgf-m)
----------
----------
T1=2.9~4.9N-m(0.3~0.5kgf-m) T2=2.5N-m(0.25kgf-m)
----------
Timing setting
(1)Pump vertical direction
(2)Key groove position at No. 1 cylinder's beginning of injection position (at BTDC: aa).
(3)Position of the key groove of the No. 1 cylinder at B.T.D.C. bb (fix the governor flyweight at this position for delivery).
(4)B.T.D.C.: aa
(5)At second timing adjustment, set the camshaft at the * position and tighten the flyweight locknut.
(6)Align the flyweight's timing gear position with the lockpin groove and then fully tighten the flyweight to the camshaft.
(7)Remove the lock pin and adjust the governor. Reinstall the lock pin to fix the flyweight for delivery.
