(2)Tolerance for racks not indicated: +-0.05mm.
(3)RACK LIMIT (When hydraulic cylinder is OFF)
(4)Boost compensator stroke: BCL
(5)When hydraulic cylinder ON: P1
(6)Rack difference between N = N1 and N = N2
(7)Adjust the secondary timing before adjusting the governor.

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.
