0000001901 M-CSD ADJUSTMENT

M-CSD adjustment 1. Fixing the M-CSD (1)At roller holder advance angle d, adjust the lever shaft ball pin so that it contacts the roller holder. (2)At this time, adjust the position of the M-CSD lever (A) using adjusting screw (C) so that the clearance a between the M-CSD lever (A) and the stopper (B) becomes L1. Then fix using nut (D). Tightening torque T1. 2. Fixing CSD lever plate (E) (1)Make the clearance between the CSD lever (A) and the stopper (B) L2. (2)Fix the CSD lever plate (E) using the bolt (F) so that the clearance b between the intermediate lever (G)'s roller (H) and the CSD lever plate is L3. Tightening torque T2. 3. Fixing the FICD screw (I) (1)Move the CSD lever (A) through its full stroke. (2)Adjust the intermediate lever G's FICD lever screw I so that the control lever K's position is e (the gap c between the control lever and the screw M is L4). Then fix using the nut J. Tightening torque T1. 4. V-FICD adjustment (1)Move the actuator O through its full stroke. (2)Adjust the position of the actuator (O) so that the control lever (K)'s position is f [the clearance between the control lever (K) and the screw (M) is c = L5]. Then, fix using the bolt (P). Tightening torque T1.

Tooling and Equipment
The tools shown in Chart F, Tooling for Finding Top Center (TC) Position, are required to complete the procedure.

( 1 ) Refer to the nomenclature chart at the beginning of this manual for item identification.Procedure
Illustration 39 g03425683
Timing Bolt Location (35) 8T-4177 Timing Bolt (36) Timing Hole (37) Flywheel HousingNote: Depending on engine application, timing hole (36) is located at either the left front face or the right front face of the flywheel housing.
Remove plug from the timing hole (36) on the front of the flywheel housing.
Rotate the engine with four large bolts on the front of the crankshaft. Do not use the eight small bolts on the front of the crankshaft pulley as this could cause damage to the engine.
Put 8T-4177 Bolt (35) in hole. Turn the engine flywheel counterclockwise until the timing bolt engages with the threaded hole in the flywheel.Note: If the flywheel is turned beyond the point the timing bolt engages in the threaded hole, the flywheel must be turned back at least 30 degrees clockwise. Again, turn the flywheel counterclockwise until the timing bolt engages with the threaded hole. This procedure makes sure that the play is removed from the gears when number 1 piston is put on TC.
Remove the cylinder head valve cover.
Illustration 40 g03425694
Valve Cover Removed
The intake and the exhaust valves for the number 1 cylinder are fully closed if number 1 piston is on the compression stroke and the rocker arms can be moved by hand. If the rocker arms cannot be moved and the valves are slightly open, the number 1 piston is on the exhaust strike. Refer to Chart E, Crankshaft Positions for Fuel Timing Settings, to determine which cylinders can be checked/adjusted (determined by stroke position of crankshaft when timing bolt is installed).Note: When the actual stroke position is identified, and the other stroke position is desired, it is necessary to remove the timing bolt from the flywheel. Turn the flywheel counterclockwise 360 degrees, and reinstall the timing bolt.
After TC position for a particular stroke is obtained and adjustments are made, remove the timing bolt and turn the flywheel counterclockwise 360 degrees. This will put number 1 piston at TC position on the other stroke. Install timing bolt in the flywheel and complete adjustments for remaining cylinders.Removal and Installation of Unit Fuel Injectors
